Amazon QuickSight is a fully managed cloud business intelligence system that gives you Fast & Easy to Use Business Analytics for Big Data. QuickSight makes business analytics available to organizations of all shapes and sizes, with the ability to access data that is stored in your Amazon Redshift data warehouse, your Amazon Relational Database Service (RDS) relational databases, flat files in S3, and (via connectors) data stored in on-premises MySQL, PostgreSQL, and SQL Server databases. QuickSight scales to accommodate tens, hundreds, or thousands of users per organization.
Today we are launching a new, session-based pricing option for QuickSight, along with additional region support and other important new features. Let’s take a look at each one:
Pay-per-Session Pricing Our customers are making great use of QuickSight and take full advantage of the power it gives them to connect to data sources, create reports, and and explore visualizations.
However, not everyone in an organization needs or wants such powerful authoring capabilities. Having access to curated data in dashboards and being able to interact with the data by drilling down, filtering, or slicing-and-dicing is more than adequate for their needs. Subscribing them to a monthly or annual plan can be seen as an unwarranted expense, so a lot of such casual users end up not having access to interactive data or BI.
In order to allow customers to provide all of their users with interactive dashboards and reports, the Enterprise Edition of Amazon QuickSight now allows Reader access to dashboards on a Pay-per-Session basis. QuickSight users are now classified as Admins, Authors, or Readers, with distinct capabilities and prices:
Authors have access to the full power of QuickSight; they can establish database connections, upload new data, create ad hoc visualizations, and publish dashboards, all for $9 per month (Standard Edition) or $18 per month (Enterprise Edition).
Readers can view dashboards, slice and dice data using drill downs, filters and on-screen controls, and download data in CSV format, all within the secure QuickSight environment. Readers pay $0.30 for 30 minutes of access, with a monthly maximum of $5 per reader.
Admins have all authoring capabilities, and can manage users and purchase SPICE capacity in the account. The QuickSight admin now has the ability to set the desired option (Author or Reader) when they invite members of their organization to use QuickSight. They can extend Reader invites to their entire user base without incurring any up-front or monthly costs, paying only for the actual usage.
A New Region QuickSight is now available in the Asia Pacific (Tokyo) Region:
The UI is in English, with a localized version in the works.
Hourly Data Refresh Enterprise Edition SPICE data sets can now be set to refresh as frequently as every hour. In the past, each data set could be refreshed up to 5 times a day. To learn more, read Refreshing Imported Data.
Access to Data in Private VPCs This feature was launched in preview form late last year, and is now available in production form to users of the Enterprise Edition. As I noted at the time, you can use it to implement secure, private communication with data sources that do not have public connectivity, including on-premises data in Teradata or SQL Server, accessed over an AWS Direct Connect link. To learn more, read Working with AWS VPC.
Parameters with On-Screen Controls QuickSight dashboards can now include parameters that are set using on-screen dropdown, text box, numeric slider or date picker controls. The default value for each parameter can be set based on the user name (QuickSight calls this a dynamic default). You could, for example, set an appropriate default based on each user’s office location, department, or sales territory. Here’s an example:
URL Actions for Linked Dashboards You can now connect your QuickSight dashboards to external applications by defining URL actions on visuals. The actions can include parameters, and become available in the Details menu for the visual. URL actions are defined like this:
You can use this feature to link QuickSight dashboards to third party applications (e.g. Salesforce) or to your own internal applications. Read Custom URL Actions to learn how to use this feature.
Dashboard Sharing You can now share QuickSight dashboards across every user in an account.
Larger SPICE Tables The per-data set limit for SPICE tables has been raised from 10 GB to 25 GB.
Upgrade to Enterprise Edition The QuickSight administrator can now upgrade an account from Standard Edition to Enterprise Edition with a click. This enables provisioning of Readers with pay-per-session pricing, private VPC access, row-level security for dashboards and data sets, and hourly refresh of data sets. Enterprise Edition pricing applies after the upgrade.
Available Now Everything I listed above is available now and you can start using it today!

The adoption of Apache Spark has increased significantly over the past few years, and running Spark-based application pipelines is the new normal. Spark jobs that are in an ETL (extract, transform, and load) pipeline have different requirements—you must handle dependencies in the jobs, maintain order during executions, and run multiple jobs in parallel. In most of these cases, you can use workflow scheduler tools like Apache Oozie, Apache Airflow, and even Cron to fulfill these requirements.
Apache Oozie is a widely used workflow scheduler system for Hadoop-based jobs. However, its limited UI capabilities, lack of integration with other services, and heavy XML dependency might not be suitable for some users. On the other hand, Apache Airflow comes with a lot of neat features, along with powerful UI and monitoring capabilities and integration with several AWS and third-party services. However, with Airflow, you do need to provision and manage the Airflow server. The Cron utility is a powerful job scheduler. But it doesn’t give you much visibility into the job details, and creating a workflow using Cron jobs can be challenging.
What if you have a simple use case, in which you want to run a few Spark jobs in a specific order, but you don’t want to spend time orchestrating those jobs or maintaining a separate application? You can do that today in a serverless fashion using AWS Step Functions. You can create the entire workflow in AWS Step Functions and interact with Spark on Amazon EMR through Apache Livy.
In this post, I walk you through a list of steps to orchestrate a serverless Spark-based ETL pipeline using AWS Step Functions and Apache Livy.
Input data
For the source data for this post, I use the New York City Taxi and Limousine Commission (TLC) trip record data. For a description of the data, see this detailed dictionary of the taxi data. In this example, we’ll work mainly with the following three columns for the Spark jobs.
Column name
Column description
RateCodeID
Represents the rate code in effect at the end of the trip (for example, 1 for standard rate, 2 for JFK airport, 3 for Newark airport, and so on).
FareAmount
Represents the time-and-distance fare calculated by the meter.
TripDistance
Represents the elapsed trip distance in miles reported by the taxi meter.
The trip data is in comma-separated values (CSV) format with the first row as a header. To shorten the Spark execution time, I trimmed the large input data to only 20,000 rows. During the deployment phase, the input file tripdata.csv is stored in Amazon S3 in the <<your-bucket>>/emr-step-functions/input/ folder.
The following image shows a sample of the trip data:
Solution overview
The next few sections describe how Spark jobs are created for this solution, how you can interact with Spark using Apache Livy, and how you can use AWS Step Functions to create orchestrations for these Spark applications.
At a high level, the solution includes the following steps:
Trigger the AWS Step Function state machine by passing the input file path.
The first stage in the state machine triggers an AWS Lambda
The Lambda function interacts with Apache Spark running on Amazon EMR using Apache Livy, and submits a Spark job.
The state machine waits a few seconds before checking the Spark job status.
Based on the job status, the state machine moves to the success or failure state.
Subsequent Spark jobs are submitted using the same approach.
The state machine waits a few seconds for the job to finish.
The job finishes, and the state machine updates with its final status.
Let’s take a look at the Spark application that is used for this solution.
Spark jobs
For this example, I built a Spark jar named spark-taxi.jar. It has two different Spark applications:
MilesPerRateCode – The first job that runs on the Amazon EMR cluster. This job reads the trip data from an input source and computes the total trip distance for each rate code. The output of this job consists of two columns and is stored in Apache Parquet format in the output path.
The following are the expected output columns:
rate_code – Represents the rate code for the trip.
total_distance – Represents the total trip distance for that rate code (for example, sum(trip_distance)).
RateCodeStatus – The second job that runs on the EMR cluster, but only if the first job finishes successfully. This job depends on two different input sets:
csv – The same trip data that is used for the first Spark job.
miles-per-rate – The output of the first job.
This job first reads the tripdata.csv file and aggregates the fare_amount by the rate_code. After this point, you have two different datasets, both aggregated by rate_code. Finally, the job uses the rate_code field to join two datasets and output the entire rate code status in a single CSV file.
The output columns are as follows:
rate_code_id – Represents the rate code type.
total_distance – Derived from first Spark job and represents the total trip distance.
total_fare_amount – A new field that is generated during the second Spark application, representing the total fare amount by the rate code type.
Note that in this case, you don’t need to run two different Spark jobs to generate that output. The goal of setting up the jobs in this way is just to create a dependency between the two jobs and use them within AWS Step Functions.
Both Spark applications take one input argument called rootPath. It’s the S3 location where the Spark job is stored along with input and output data. Here is a sample of the final output:
The next section discusses how you can use Apache Livy to interact with Spark applications that are running on Amazon EMR.
Using Apache Livy to interact with Apache Spark
Apache Livy provides a REST interface to interact with Spark running on an EMR cluster. Livy is included in Amazon EMR release version 5.9.0 and later. In this post, I use Livy to submit Spark jobs and retrieve job status. When Amazon EMR is launched with Livy installed, the EMR master node becomes the endpoint for Livy, and it starts listening on port 8998 by default. Livy provides APIs to interact with Spark.
Let’s look at a couple of examples how you can interact with Spark running on Amazon EMR using Livy.
To list active running jobs, you can execute the following from the EMR master node:
curl localhost:8998/sessions
If you want to do the same from a remote instance, just change localhost to the EMR hostname, as in the following (port 8998 must be open to that remote instance through the security group):
Through Spark submit, you can pass multiple arguments for the Spark job and Spark configuration settings. You can also do that using Livy, by passing the S3 path through the args parameter, as shown following:
curl -X POST – data '{"file": "s3://<<bucket-location>>/spark.jar", "className": "com.example.SparkApp", “args”: [“s3://bucket-path”]}' -H "Content-Type: application/json" http://ec2-xx-xx-xx-xx.compute-1.amazonaws.com:8998/batches
All Apache Livy REST calls return a response as JSON, as shown in the following image:
If you want to pretty-print that JSON response, you can pipe command with Python’s JSON tool as follows:
For a detailed list of Livy APIs, see the Apache Livy REST API page. This post uses GET /batches and POST /batches.
In the next section, you create a state machine and orchestrate Spark applications using AWS Step Functions.
Using AWS Step Functions to create a Spark job workflow
AWS Step Functions automatically triggers and tracks each step and retries when it encounters errors. So your application executes in order and as expected every time. To create a Spark job workflow using AWS Step Functions, you first create a Lambda state machine using different types of states to create the entire workflow.
First, you use the Task state—a simple state in AWS Step Functions that performs a single unit of work. You also use the Wait state to delay the state machine from continuing for a specified time. Later, you use the Choice state to add branching logic to a state machine.
The following is a quick summary of how to use different states in the state machine to create the Spark ETL pipeline:
Task state – Invokes a Lambda function. The first Task state submits the Spark job on Amazon EMR, and the next Task state is used to retrieve the previous Spark job status.
Wait state – Pauses the state machine until a job completes execution.
Choice state – Each Spark job execution can return a failure, an error, or a success state So, in the state machine, you use the Choice state to create a rule that specifies the next action or step based on the success or failure of the previous step.
Here is one of my Task states, MilesPerRateCode, which simply submits a Spark job:
"MilesPerRate Job": {
"Type": "Task",
"Resource":"arn:aws:lambda:us-east-1:xxxxxx:function:blog-miles-per-rate-job-submit-function",
"ResultPath": "$.jobId",
"Next": "Wait for MilesPerRate job to complete"
}
This Task state configuration specifies the Lambda function to execute. Inside the Lambda function, it submits a Spark job through Livy using Livy’s POST API. Using ResultPath, it tells the state machine where to place the result of the executing task. As discussed in the previous section, Spark submit returns the session ID, which is captured with $.jobId and used in a later state.
The following code section shows the Lambda function, which is used to submit the MilesPerRateCode job. It uses the Python request library to submit a POST against the Livy endpoint hosted on Amazon EMR and passes the required parameters in JSON format through payload. It then parses the response, grabs id from the response, and returns it. The Next field tells the state machine which state to go to next.
Just like in the MilesPerRate job, another state submits the RateCodeStatus job, but it executes only when all previous jobs have completed successfully.
Here is the Task state in the state machine that checks the Spark job status:
Just like other states, the preceding Task executes a Lambda function, captures the result (represented by jobStatus), and passes it to the next state. The following is the Lambda function that checks the Spark job status based on a given session ID:
In the Choice state, it checks the Spark job status value, compares it with a predefined state status, and transitions the state based on the result. For example, if the status is success, move to the next state (RateCodeJobStatus job), and if it is dead, move to the MilesPerRate job failed state.
To set up this entire solution, you need to create a few AWS resources. To make it easier, I have created an AWS CloudFormation template. This template creates all the required AWS resources and configures all the resources that are needed to create a Spark-based ETL pipeline on AWS Step Functions.
This CloudFormation template requires you to pass the following four parameters during initiation.
Parameter
Description
ClusterSubnetID
The subnet where the Amazon EMR cluster is deployed and Lambda is configured to talk to this subnet.
KeyName
The name of the existing EC2 key pair to access the Amazon EMR cluster.
VPCID
The ID of the virtual private cloud (VPC) where the EMR cluster is deployed and Lambda is configured to talk to this VPC.
S3RootPath
The Amazon S3 path where all required files (input file, Spark job, and so on) are stored and the resulting data is written.
IMPORTANT: These templates are designed only to show how you can create a Spark-based ETL pipeline on AWS Step Functions using Apache Livy. They are not intended for production use without modification. And if you try this solution outside of the us-east-1 Region, download the necessary files from s3://aws-data-analytics-blog/emr-step-functions, upload the files to the buckets in your Region, edit the script as appropriate, and then run it.
To launch the CloudFormation stack, choose Launch Stack:
Launching this stack creates the following list of AWS resources.
Logical ID
Resource Type

StepFunctionsStateExecutionRole
IAM role

EMR cluster where Livy is running and where the job is placed.
During the AWS CloudFormation deployment phase, it sets up S3 paths for input and output. Input files are stored in the <<s3-root-path>>/emr-step-functions/input/ path, whereas spark-taxi.jar is copied under <<s3-root-path>>/emr-step-functions/.
The following screenshot shows how the S3 paths are configured after deployment. In this example, I passed a bucket that I created in the AWS account s3://tm-app-demos for the S3 root path.
If the CloudFormation template completed successfully, you will see Spark-ETL-State-Machine in the AWS Step Functions dashboard, as follows:
Choose the Spark-ETL-State-Machine state machine to take a look at this implementation. The AWS CloudFormation template built the entire state machine along with its dependent Lambda functions, which are now ready to be executed.
On the dashboard, choose the newly created state machine, and then choose New execution to initiate the state machine. It asks you to pass input in JSON format. This input goes to the first state MilesPerRate Job, which eventually executes the Lambda function blog-miles-per-rate-job-submit-function.
Pass the S3 root path as input:
{
“rootPath”: “s3://tm-app-demos”
}
Then choose Start Execution:
The rootPath value is the same value that was passed when creating the CloudFormation stack. It can be an S3 bucket location or a bucket with prefixes, but it should be the same value that is used for AWS CloudFormation. This value tells the state machine where it can find the Spark jar and input file, and where it will write output files. After the state machine starts, each state/task is executed based on its definition in the state machine.
At a high level, the following represents the flow of events:
Execute the first Spark job, MilesPerRate.
The Spark job reads the input file from the location <<rootPath>>/emr-step-functions/input/tripdata.csv. If the job finishes successfully, it writes the output data to <<rootPath>>/emr-step-functions/miles-per-rate.
If the Spark job fails, it transitions to the error state MilesPerRate job failed, and the state machine stops. If the Spark job finishes successfully, it transitions to the RateCodeStatus Job state, and the second Spark job is executed.
If the second Spark job fails, it transitions to the error state RateCodeStatus job failed, and the state machine stops with the Failed status.
If this Spark job completes successfully, it writes the final output data to the <<rootPath>>/emr-step-functions/rate-code-status/ It also transitions the RateCodeStatus job finished state, and the state machine ends its execution with the Success status.
This following screenshot shows a successfully completed Spark ETL state machine:
The right side of the state machine diagram shows the details of individual states with their input and output.
When you execute the state machine for the second time, it fails because the S3 path already exists. The state machine turns red and stops at MilePerRate job failed. The following image represents that failed execution of the state machine:
You can also check your Spark application status and logs by going to the Amazon EMR console and viewing the Application history tab:
I hope this walkthrough paints a picture of how you can create a serverless solution for orchestrating Spark jobs on Amazon EMR using AWS Step Functions and Apache Livy. In the next section, I share some ideas for making this solution even more elegant.
Next steps
The goal of this post is to show a simple example that uses AWS Step Functions to create an orchestration for Spark-based jobs in a serverless fashion. To make this solution robust and production ready, you can explore the following options:
In this example, I manually initiated the state machine by passing the rootPath as input. You can instead trigger the state machine automatically. To run the ETL pipeline as soon as the files arrive in your S3 bucket, you can pass the new file path to the state machine. Because CloudWatch Events supports AWS Step Functions as a target, you can create a CloudWatch rule for an S3 event. You can then set AWS Step Functions as a target and pass the new file path to your state machine. You’re all set!
You can also improve this solution by adding an alerting mechanism in case of failures. To do this, create a Lambda function that sends an alert email and assigns that Lambda function to a Fail That way, when any part of your state fails, it triggers an email and notifies the user.
If you want to submit multiple Spark jobs in parallel, you can use the Parallel state type in AWS Step Functions. The Parallel state is used to create parallel branches of execution in your state machine.
With Lambda and AWS Step Functions, you can create a very robust serverless orchestration for your big data workload.
Cleaning up
When you’ve finished testing this solution, remember to clean up all those AWS resources that you created using AWS CloudFormation. Use the AWS CloudFormation console or AWS CLI to delete the stack named Blog-Spark-ETL-Step-Functions.
Summary
In this post, I showed you how to use AWS Step Functions to orchestrate your Spark jobs that are running on Amazon EMR. You used Apache Livy to submit jobs to Spark from a Lambda function and created a workflow for your Spark jobs, maintaining a specific order for job execution and triggering different AWS events based on your job’s outcome. Go ahead—give this solution a try, and share your experience with us!

When I talk with customers and partners, I find that they are in different stages in the adoption of DevOps methodologies. They are automating the creation of application artifacts and the deployment of their applications to different infrastructure environments. In many cases, they are creating and supporting multiple applications using a variety of coding languages and artifacts.
The management of these processes and artifacts can be challenging, but using the right tools and methodologies can simplify the process.
In this post, I will show you how you can automate the creation and storage of application artifacts through the implementation of a pipeline and custom deploy action in AWS CodePipeline. The example includes a Node.js code base stored in an AWS CodeCommit repository. A Node Package Manager (npm) artifact is built from the code base, and the build artifact is published to a JFrogArtifactory npm repository.
I frequently recommend AWS CodePipeline, the AWS continuous integration and continuous delivery tool. You can use it to quickly innovate through integration and deployment of new features and bug fixes by building a workflow that automates the build, test, and deployment of new versions of your application. And, because AWS CodePipeline is extensible, it allows you to create a custom action that performs customized, automated actions on your behalf.
JFrog’s Artifactory is a universal binary repository manager where you can manage multiple applications, their dependencies, and versions in one place. Artifactory also enables you to standardize the way you manage your package types across all applications developed in your company, no matter the code base or artifact type.
If you already have a Node.js CodeCommit repository, a JFrog Artifactory host, and would like to automate the creation of the pipeline, including the custom action and CodeBuild project, you can use this AWS CloudFormationtemplate to create your AWS CloudFormation stack.
This figure shows the path defined in the pipeline for this project. It starts with a change to Node.js source code committed to a private code repository in AWS CodeCommit. With this change, CodePipeline triggers AWS CodeBuild to create the npm package from the node.js source code. After the build, CodePipeline triggers the custom action job worker to commit the build artifact to the designated artifact repository in Artifactory.
This blog post assumes you have already:
· Created a CodeCommit repository that contains a Node.js project.
· Configured a two-stage pipeline in AWS CodePipeline.
The Source stage of the pipeline is configured to poll the Node.js CodeCommit repository. The Build stage is configured to use a CodeBuild project to build the npm package using a buildspec.yml file located in the code repository.
If you do not have a Node.js repository, you can create a CodeCommit repository that contains this simple ‘Hello World’ project. This project also includes a buildspec.yml file that is used when you define your CodeBuild project. It defines the steps to be taken by CodeBuild to create the npm artifact.
If you do not already have a pipeline set up in CodePipeline, you can use this template to create a pipeline with a CodeCommit source action and a CodeBuild build action through the AWS Command Line Interface (AWS CLI). If you do not want to install the AWS CLI on your local machine, you can use AWS Cloud9, our managed integrated development environment (IDE), to interact with AWS APIs.
In your development environment, open your favorite editor and fill out the template with values appropriate to your project. For information, see the readme in the GitHub repository.
Use this CLI command to create the pipeline from the template:
aws codepipeline create-pipeline – cli-input-json file://source-build-actions-codepipeline.json – region 'us-west-2'
It creates a pipeline that has a CodeCommit source action and a CodeBuild build action.
Integrating JFrog Artifactory
JFrog Artifactory provides default repositories for your project needs. For my NPM package repository, I am using the default virtual npm repository (named npm) that is available in Artifactory Pro. You might want to consider creating a repository per project but for the example used in this post, using the default lets me get started without having to configure a new repository.
I can use the steps in the Set Me Up -> npm section on the landing page to configure my worker to interact with the default NPM repository.
Describes the required values to run the custom action. I will define my custom action in the ‘Deploy’ category, identify the provider as ‘Artifactory’, of version ‘1’, and specify a variety of configurationProperties whose values will be defined when this stage is added to my pipeline.
Polls CodePipeline for a job, scanning for its action-definition properties. In this blog post, after a job has been found, the job worker does the work required to publish the npm artifact to the Artifactory repository.

There are seven sections to the custom action definition:
category: This is the stage in which you will be creating this action. It can be Source, Build, Deploy, Test, Invoke, Approval. Except for source actions, the category section simply allows us to organize our actions. I am setting the category for my action as ‘Deploy’ because I’m using it to publish my node artifact to my Artifactory instance.
configurationProperties: These are the parameters or variables required for your project to authenticate and commit your artifact. In the case of my custom worker, I need:
TypeOfArtifact: In this case, npm, because it’s for the Node Package Manager.
RepoKey: The name of the repository. In this case, it’s the default npm.
UserName and Password for the user to authenticate with the Artifactory repository.
EmailAddress used to authenticate with the repository.
Artifactory host name or IP address.
provider: The name you define for your custom action stage. I have named the provider Artifactory.
version: Version number for the custom action. Because this is the first version, I set the version number to 1.
entityUrlTemplate: This URL is presented to your users for the deploy stage along with the title you define in your provider. The link takes the user to their artifact repository page in the Artifactory host.
inputArtifactDetails: The number of artifacts to expect from the previous stage in the pipeline.
outputArtifactDetails: The number of artifacts that should be the result from the custom action stage. Later in this blog post, I define 0 for my output artifacts because I am publishing the artifact to the Artifactory repository as the final action.
After I define the custom action in a JSON file, I use the AWS CLI to create the custom action type in CodePipeline:
After I create the custom action type in the same region as my pipeline, I edit the pipeline to add a Deploy stage and configure it to use the custom action I created for Artifactory:
I have created a custom worker for the actions required to commit the npm artifact to the Artifactory repository. The worker is in Python and it runs in a loop on an Amazon EC2 instance. My custom worker polls for a deploy job and publishes the NPM artifact to the Artifactory repository.
The EC2 instance is running Amazon Linux and has an IAM instance role attached that gives the worker permission to access CodePipeline. The worker process is as follows:
Take the configuration properties from the custom worker and poll CodePipeline for a custom action job.
After there is a job in the job queue with the appropriate category, provider, and version, acknowledge the job.
Download the zipped artifact created in the previous Build stage from the provided S3 buckets with the provided temporary credentials.
Unzip the artifact into a temporary directory.
A user-defined Artifactory user name and password is used to receive a temporary API key from Artifactory.
To avoid having to write the password to a file, use that temporary API key and user name to authenticate with the NPM repository.
Publish the Node.js package to the specified repository.
Because I am running my custom worker on an Amazon Linux EC2 instance, I installed npm with the following command:
sudo yum install nodejs npm – enablerepo=epel
For my custom worker, I used pip to install the required Python libraries:
pip install boto3 requests
For a full Python package list, see requirements.txt in the GitHub repository.
Let’s take a look at some of the code snippets from the worker.
First, the worker polls for jobs:
def action_type():
ActionType = {
'category': 'Deploy',
'owner': 'Custom',
'provider': 'Artifactory',
'version': '1' }
return(ActionType)
def poll_for_jobs():
try:
artifactory_action_type = action_type()
print(artifactory_action_type)
jobs = codepipeline.poll_for_jobs(actionTypeId=artifactory_action_type)
while not jobs['jobs']:
time.sleep(10)
jobs = codepipeline.poll_for_jobs(actionTypeId=artifactory_action_type)
if jobs['jobs']:
print('Job found')
return jobs['jobs'][0]
except ClientError as e:
print("Received an error: %s" % str(e))
raise
When there is a job in the queue, the poller returns a number of values from the queue such as jobId, the input and output S3 buckets for artifacts, temporary credentials to access the S3 buckets, and other configuration details from the stage in the pipeline.
After successfully receiving the job details, the worker sends an acknowledgement to CodePipeline to ensure that the work on the job is not duplicated by other workers watching for the same job:
def job_acknowledge(jobId, nonce):
try:
print('Acknowledging job')
result = codepipeline.acknowledge_job(jobId=jobId, nonce=nonce)
return result
except Exception as e:
print("Received an error when trying to acknowledge the job: %s" % str(e))
raise
With the job now acknowledged, the worker publishes the source code artifact into the desired repository. The worker gets the value of the artifact S3 bucket and objectKey from the inputArtifacts in the response from the poll_for_jobs API request. Next, the worker creates a new directory in /tmp and downloads the S3 object into this directory:
def get_bucket_location(bucketName, init_client):
region = init_client.get_bucket_location(Bucket=bucketName)['LocationConstraint']
if not region:
region = 'us-east-1'
return region
def get_s3_artifact(bucketName, objectKey, ak, sk, st):
init_s3 = boto3.client('s3')
region = get_bucket_location(bucketName, init_s3)
session = Session(aws_access_key_id=ak,
aws_secret_access_key=sk,
aws_session_token=st)
s3 = session.resource('s3',
region_name=region,
config=botocore.client.Config(signature_version='s3v4'))
try:
tempdirname = tempfile.mkdtemp()
except OSError as e:
print('Could not write temp directory %s' % tempdirname)
raise
bucket = s3.Bucket(bucketName)
obj = bucket.Object(objectKey)
filename = tempdirname + '/' + objectKey
try:
if os.path.dirname(objectKey):
directory = os.path.dirname(filename)
os.makedirs(directory)
print('Downloading the %s object and writing it to disk in %s location' % (objectKey, tempdirname))
with open(filename, 'wb') as data:
obj.download_fileobj(data)
except ClientError as e:
print('Downloading the object and writing the file to disk raised this error: ' + str(e))
raise
return(filename, tempdirname)
Because the downloaded artifact from S3 is a zip file, the worker must unzip it first. To have a clean area in which to work, I extract the downloaded zip archive into a new directory:
def unzip_codepipeline_artifact(artifact, origtmpdir):
# create a new temp directory
# Unzip artifact into new directory
try:
newtempdir = tempfile.mkdtemp()
print('Extracting artifact %s into temporary directory %s' % (artifact, newtempdir))
zip_ref = zipfile.ZipFile(artifact, 'r')
zip_ref.extractall(newtempdir)
zip_ref.close()
shutil.rmtree(origtmpdir)
return(os.listdir(newtempdir), newtempdir)
except OSError as e:
if e.errno != errno.EEXIST:
shutil.rmtree(newtempdir)
raise
The worker now has the npm package that I want to store in my Artifactory NPM repository.
To authenticate with the NPM repository, the worker requests a temporary token from the Artifactory host. After receiving this temporary token, it creates a .npmrc file in the worker user’s home directory that includes a hash of the user name and temporary token. After it has authenticated, the worker runs npm config set registry <URL OF REPOSITORY> to configure the npm registry value to be the Artifactory host. Next, the worker runs npm publish –registry <URL OF REPOSITORY>, which publishes the node package to the NPM repository in the Artifactory host.
def push_to_npm(configuration, artifact_list, temp_dir, jobId):
reponame = configuration['RepoKey']
art_type = configuration['TypeOfArtifact']
print("Putting artifact into NPM repository " + reponame)
token, hostname, username = gen_artifactory_auth_token(configuration)
npmconfigfile = create_npmconfig_file(configuration, username, token)
url = hostname + '/artifactory/api/' + art_type + '/' + reponame
print("Changing directory to " + str(temp_dir))
os.chdir(temp_dir)
try:
print("Publishing following files to the repository: %s " % os.listdir(temp_dir))
print("Sending artifact to Artifactory NPM registry URL: " + url)
subprocess.call(["npm", "config", "set", "registry", url])
req = subprocess.call(["npm", "publish", "--registry", url])
print("Return code from npm publish: " + str(req))
if req != 0:
err_msg = "npm ERR! Recieved non OK response while sending response to Artifactory. Return code from npm publish: " + str(req)
signal_failure(jobId, err_msg)
else:
signal_success(jobId)
except requests.exceptions.RequestException as e:
print("Received an error when trying to commit artifact %s to repository %s: " % (str(art_type), str(configuration['RepoKey']), str(e)))
raise
return(req, npmconfigfile)
If the return value from publishing to the repository is not 0, the worker signals a failure to CodePipeline. If the value is 0, the worker signals success to CodePipeline to indicate that the stage of the pipeline has been completed successfully.
For the custom worker code, see npm_job_worker.py in the GitHub repository.
I run my custom worker on an EC2 instance using the command python npm_job_worker.py, with an optional --version flag that can be used to specify worker versions other than 1. Then I trigger a release change in my pipeline:
From my custom worker output logs, I have just committed a package named node_example at version 1.0.3:
On artifact: index.js
Committing to the repo: https://artifactory.myexamplehost.com/artifactory/api/npm/npm
Sending artifact to Artifactory URL: https:// artifactoryhost.myexamplehost.com/artifactory/api/npm/npm
npm config: 0
npm http PUT https://artifactory.myexamplehost.com/artifactory/api/npm/npm/node_example
npm http 201 https://artifactory.myexamplehost.com/artifactory/api/npm/npm/node_example
+ [email protected]
Return code from npm publish: 0
Signaling success to CodePipeline
After that has been built successfully, I can find my artifact in my Artifactory repository:
To help you automate this process, I have created this AWS CloudFormation template that automates the creation of the CodeBuild project, the custom action, and the CodePipeline pipeline. It also launches the Amazon EC2-based custom job worker in an AWS Auto Scaling group. This template requires you to have a VPC and CodeCommit repository for your Node.js project. If you do not currently have a VPC in which you want to run your custom worker EC2 instances, you can use this AWS QuickStart to create one. If you do not have an existing Node.js project, I’ve provided a sample project in the GitHub repository.
Conclusion
I‘ve shown you the steps to integrate your JFrog Artifactory repository with your CodePipeline workflow. I’ve shown you how to create a custom action in CodePipeline and how to create a custom worker that works in your CI/CD pipeline.

We’re usually averse to buzzwords at HackSpace magazine, but not this month: in issue 7, we’re taking a deep dive into the Internet of Things.
Internet of Things (IoT)
To many people, IoT is a shady term used by companies to sell you something you already own, but this time with WiFi; to us, it’s a way to make our builds smarter, more useful, and more connected. In HackSpace magazine #7, you can join us on a tour of the boards that power IoT projects, marvel at the ways in which other makers are using IoT, and get started with your first IoT project!
Awesome projects
DIY retro computing: this issue, we’re taking our collective hat off to Spencer Owen. He stuck his home-brew computer on Tindie thinking he might make a bit of beer money — now he’s paying the mortgage with his making skills and inviting others to build modules for his machine. And if that tickles your fancy, why not take a crack at our Z80 tutorial? Get out your breadboard, assemble your jumper wires, and prepare to build a real-life computer!
Shameless patriotism: combine Lego, Arduino, and the car of choice for 1960 gold bullion thieves, and you’ve got yourself a groovy weekend project. We proudly present to you one man’s epic quest to add LED lights (controllable via a smartphone!) to his daughter’s LEGO Mini Cooper.
Makerspaces
Patriotism intensifies: for the last 200-odd years, the Black Country has been a hotbed of making. Urban Hax, based in Walsall, is the latest makerspace to show off its riches in the coveted Space of the Month pages. Every space has its own way of doing things, but not every space has a portrait of Rob Halford on the wall. All hail!
Diversity: advice on diversity often boils down to ‘Be nice to people’, which might feel more vague than actionable. This is where we come in to help: it is truly worth making the effort to give people of all backgrounds access to your makerspace, so we take a look at why it’s nice to be nice, and at the ways in which one makerspace has put niceness into practice — with great results.
And there’s more!
We also show you how to easily calculate the size and radius of laser-cut gears, use a bank of LEDs to etch PCBs in your own mini factory, and use chemistry to mess with your lunch menu.
All this plus much, much more waits for you in HackSpace magazine issue 7!
Get your copy of HackSpace magazine
If you like the sound of that, you can find HackSpace magazine in WHSmith, Tesco, Sainsbury’s, and independent newsagents in the UK. If you live in the US, check out your local Barnes & Noble, Fry’s, or Micro Center next week. We’re also shipping to stores in Australia, Hong Kong, Canada, Singapore, Belgium, and Brazil, so be sure to ask your local newsagent whether they’ll be getting HackSpace magazine.
If pressed, I will admit to thinking that, if NIS was good enough for Charles Babbage, it’s good enough for me. I am therefore not a huge fan of LDAP; I feel I can detect in it the heavy hand of the ITU, which seems to wish to apply X.500 to everything. Nevertheless, for secure, distributed, multi-platform identity management it’s quite hard to beat. If you decide to run an LDAP server on Unix, one of the major free implementations is slapd, the core engine of the OpenLDAP project. Howard Chu is the chief architect of the project, and spoke at FLOSS 2018 about the upcoming 2.5 release. Any rumors that he might have passed the time while the room filled up by giving a short but nicely rendered fiddle recital are completely true.

Regardless of your career path, there’s no denying that attending industry events can provide helpful career development opportunities — not only for improving and expanding your skill sets, but for networking as well. According to this article from PayScale.com, experts estimate that somewhere between 70-85% of new positions are landed through networking.
Narrowing our focus to networking opportunities with cloud computing professionals who’re working on tackling some of today’s most innovative and exciting big data solutions, attending big data-focused sessions at an AWS Global Summit is a great place to start.
AWS Global Summits are free events that bring the cloud computing community together to connect, collaborate, and learn about AWS. As the name suggests, these summits are held in major cities around the world, and attract technologists from all industries and skill levels who’re interested in hearing from AWS leaders, experts, partners, and customers.
In addition to networking opportunities with top cloud technology providers, consultants and your peers in our Partner and Solutions Expo, you’ll also hone your AWS skills by attending and participating in a multitude of education and training opportunities.
Here’s a brief sampling of some of the upcoming sessions relevant to big data professionals:
Be sure to check out the main page for AWS Global Summits, where you can see which cities have AWS Summits planned for 2018, register to attend an upcoming event, or provide your information to be notified when registration opens for a future event.
As you can see from my EC2 Instance History post, we add new instance types on a regular and frequent basis. Driven by increasingly powerful processors and designed to address an ever-widening set of use cases, the size and diversity of this list reflects the equally diverse group of EC2 customers!
Near the bottom of that list you will find the new compute-intensive C5 instances. With a 25% to 50% improvement in price-performance over the C4 instances, the C5 instances are designed for applications like batch and log processing, distributed and or real-time analytics, high-performance computing (HPC), ad serving, highly scalable multiplayer gaming, and video encoding. Some of these applications can benefit from access to high-speed, ultra-low latency local storage. For example, video encoding, image manipulation, and other forms of media processing often necessitates large amounts of I/O to temporary storage. While the input and output files are valuable assets and are typically stored as Amazon Simple Storage Service (S3) objects, the intermediate files are expendable. Similarly, batch and log processing runs in a race-to-idle model, flushing volatile data to disk as fast as possible in order to make full use of compute resources.
New C5d Instances with Local Storage In order to meet this need, we are introducing C5 instances equipped with local NVMe storage. Available for immediate use in 5 regions, these instances are a great fit for the applications that I described above, as well as others that you will undoubtedly dream up! Here are the specs:
Instance Name
vCPUs
RAM
Local Storage
EBS Bandwidth

25 Gbps
Other than the addition of local storage, the C5 and C5d share the same specs. Both are powered by 3.0 GHz Intel Xeon Platinum 8000-series processors, optimized for EC2 and with full control over C-states on the two largest sizes, giving you the ability to run two cores at up to 3.5 GHz using Intel Turbo Boost Technology.
You can use any AMI that includes drivers for the Elastic Network Adapter (ENA) and NVMe; this includes the latest Amazon Linux, Microsoft Windows (Server 2008 R2, Server 2012, Server 2012 R2 and Server 2016), Ubuntu, RHEL, SUSE, and CentOS AMIs.
Here are a couple of things to keep in mind about the local NVMe storage:
Naming – You don’t have to specify a block device mapping in your AMI or during the instance launch; the local storage will show up as one or more devices (/dev/nvme*1 on Linux) after the guest operating system has booted.
Encryption – Each local NVMe device is hardware encrypted using the XTS-AES-256 block cipher and a unique key. Each key is destroyed when the instance is stopped or terminated.
Lifetime – Local NVMe devices have the same lifetime as the instance they are attached to, and do not stick around after the instance has been stopped or terminated.
Available Now C5d instances are available in On-Demand, Reserved Instance, and Spot form in the US East (N. Virginia), US West (Oregon), EU (Ireland), US East (Ohio), and Canada (Central) Regions. Prices vary by Region, and are just a bit higher than for the equivalent C5 instances.

Amazon Linux 2 is the next generation of Amazon Linux, a Linux server operating system from Amazon Web Services (AWS). Amazon Linux 2 offers a high-performance Linux environment suitable for organizations of all sizes. It supports applications ranging from small websites to enterprise-class, mission-critical platforms.
Amazon Linux 2 includes support for the LAMP (Linux/Apache/MariaDB/PHP) stack, one of the most popular platforms for deploying websites. To secure the transmission of data-in-transit to such websites and prevent eavesdropping, organizations commonly leverage Secure Sockets Layer/Transport Layer Security (SSL/TLS) services which leverage certificates to provide encryption. The LAMP stack provided by Amazon Linux 2 includes a self-signed SSL/TLS certificate. Such certificates may be fine for internal usage but are not acceptable when attestation by a certificate authority is required.
In this post, I discuss how to extend the capabilities of Amazon Linux 2 by installing Let’s Encrypt, a certificate authority provided by the Internet Security Research Group. Let’s Encrypt offers basic SSL/TLS certificates for DNS hosts at no charge that you can use to add encryption-in-transit to a single web server. For commercial or multi-server configurations, you should consider AWS Certificate Manager and Elastic Load Balancing.
Let’s Encrypt also requires the certbot package, which you install from EPEL, the Extra Packaged for Enterprise Linux collection. Although EPEL is not included with Amazon Linux 2, I show how you can install it from the Fedora Project.
Walkthrough
At a high level, you perform the following tasks for this walkthrough:
Provision a VPC, Amazon Linux 2 instance, and LAMP stack.
Install and enable the EPEL repository.
Install and configure Let’s Encrypt.
Validate the installation.
Clean up.
Prerequisites and costs
To follow along with this walkthrough, you need the following:
Accept all other default values including with regard to storage.
Create a new security group and accept the default rule that allows TCP port 22 (SSH) from everywhere (0.0.0.0/0 in IPv4). For the purposes of this walkthrough, permitting access from all IP addresses is reasonable. In a production environment, you may restrict access to different addresses.
Allocate and associate an Elastic IP address to the server when it enters the running state.
Respond “Y” to all requests for approval to install the software.
Step 3: Install and configure Let’s Encrypt
If you are no longer connected to the Amazon Linux 2 instance, connect to it at the Elastic IP address that you just created.
Install certbot, the Let’s Encrypt client to be used to obtain an SSL/TLS certificate and install it into Apache.
sudo yum install python2-certbot-apache.noarch
Respond “Y” to all requests for approval to install the software. If you see a message appear about SELinux, you can safely ignore it. This is a known issue with the latest version of certbot.
Create a DNS “A record” that maps a host name to the Elastic IP address. For this post, assume that the name of the host is lamp.example.com. If you are hosting your DNS in Amazon Route 53, do this by creating the appropriate record set.
After the “A record” has propagated, browse to lamp.example.com. The Apache test page should appear. If the page does not appear, use a tool such as nslookup on your workstation to confirm that the DNS record has been properly configured.
You are now ready to install Let’s Encrypt. Let’s Encrypt does the following:
Confirms that you have control over the DNS domain being used, by having you create a DNS TXT record using the value that it provides.
Obtains an SSL/TLS certificate.
Modifies the Apache-related scripts to use the SSL/TLS certificate and redirects users browsing the site in HTTP mode to HTTPS mode.
Use the following command to install certbot:
sudo certbot -i apache -a manual \
--preferred-challenges dns -d lamp.example.com
The options have the following meanings:
-i apache Use the Apache installer.
-a manual Authenticate domain ownership manually.
--preferred-challenges dns Use DNS TXT records for authentication challenge.
-d lamp.example.com Specify the domain for the SSL/TLS certificate.
You are prompted for the following information: E-mail address for renewals? Enter an email address for certificate renewals. Accept the terms of services? Respond as appropriate. Send your e-mail address to the EFF? Respond as appropriate. Log your current IP address? Respond as appropriate.
You are prompted to deploy a DNS TXT record with the name “_acme-challenge.lamp.example.com” with the supplied value, as shown below.
After you enter the record, wait until the TXT record propagates. To look up the TXT record to confirm the deployment, use the nslookup command in a separate command window, as shown below. Remember to use the set ty=txt command before entering the TXT record. You are prompted to select a virtual host. There is only one, so choose 1. The final prompt asks whether to redirect HTTP traffic to HTTPS. To perform the redirection, choose 2. That completes the configuration of Let’s Encrypt.
Browse to the http:// lamp.example.com site. You are redirected to the SSL/TLS page https://lamp.example.com.
To look at the encryption information, use the appropriate actions within your browser. For example, in Firefox, you can open the padlock and traverse the menus. In the encryption technical details, you can see from the “Connection Encrypted” line that traffic to the website is now encrypted using TLS 1.2.
Security note: As of the time of publication, this website also supports TLS 1.0. I recommend that you disable this protocol because of some known vulnerabilities associated with it. To do this:
Edit the file /etc/letsencrypt/options-ssl-apache.conf.
Look for the line beginning with SSLProtocol and change it to the following:
SSLProtocol all -SSLv2 -SSLv3 -TLSv1
Save the file. After you make changes to this file, Let’s Encrypt no longer automatically updates it. Periodically check your log files for recommended updates to this file.
Restart the httpd server with the following command:
sudo service httpd restart
Step 5: Cleanup
Use the following steps to avoid incurring any further costs.
Terminate the Amazon Linux 2 instance that you created.
Release the Elastic IP address that you allocated.
Revert any DNS changes that you made, including the A and TXT records.
Conclusion
Amazon Linux 2 is an excellent option for hosting websites through the LAMP stack provided by the Amazon-Linux-Extras feature. You can then enhance the security of the Apache web server by installing EPEL and Let’s Encrypt. Let’s Encrypt provisions an SSL/TLS certificate, optionally installs it for you on the Apache server, and enables data-in-transit encryption. You can get started with Amazon Linux 2 in just a few clicks.
The EU’s General Data Protection Regulation (GDPR) describes data processor and data controller roles, and some customers and AWS Partner Network (APN) partners are asking how this affects the long-established AWS Shared Responsibility Model. I wanted to take some time to help folks understand shared responsibilities for us and for our customers in context of the GDPR.
How does the AWS Shared Responsibility Model change under GDPR? The short answer – it doesn’t. AWS is responsible for securing the underlying infrastructure that supports the cloud and the services provided; while customers and APN partners, acting either as data controllers or data processors, are responsible for any personal data they put in the cloud. The shared responsibility model illustrates the various responsibilities of AWS and our customers and APN partners, and the same separation of responsibility applies under the GDPR.
AWS responsibilities as a data processor
The GDPR does introduce specific regulation and responsibilities regarding data controllers and processors. When any AWS customer uses our services to process personal data, the controller is usually the AWS customer (and sometimes it is the AWS customer’s customer). However, in all of these cases, AWS is always the data processor in relation to this activity. This is because the customer is directing the processing of data through its interaction with the AWS service controls, and AWS is only executing customer directions. As a data processor, AWS is responsible for protecting the global infrastructure that runs all of our services. Controllers using AWS maintain control over data hosted on this infrastructure, including the security configuration controls for handling end-user content and personal data. Protecting this infrastructure, is our number one priority, and we invest heavily in third-party auditors to test our security controls and make any issues they find available to our customer base through AWS Artifact. Our ISO 27018 report is a good example, as it tests security controls that focus on protection of personal data in particular.
AWS has an increased responsibility for our managed services. Examples of managed services include Amazon DynamoDB, Amazon RDS, Amazon Redshift, Amazon Elastic MapReduce, and Amazon WorkSpaces. These services provide the scalability and flexibility of cloud-based resources with less operational overhead because we handle basic security tasks like guest operating system (OS) and database patching, firewall configuration, and disaster recovery. For most managed services, you only configure logical access controls and protect account credentials, while maintaining control and responsibility of any personal data.
Customer and APN partner responsibilities as data controllers — and how AWS Services can help
Our customers can act as data controllers or data processors within their AWS environment. As a data controller, the services you use may determine how you configure those services to help meet your GDPR compliance needs. For example, AWS Services that are classified as Infrastructure as a Service (IaaS), such as Amazon EC2, Amazon VPC, and Amazon S3, are under your control and require you to perform all routine security configuration and management that would be necessary no matter where the servers were located. With Amazon EC2 instances, you are responsible for managing: guest OS (including updates and security patches), application software or utilities installed on the instances, and the configuration of the AWS-provided firewall (called a security group).
To help you realize data protection by design principles under the GDPR when using our infrastructure, we recommend you protect AWS account credentials and set up individual user accounts with Amazon Identity and Access Management (IAM) so that each user is only given the permissions necessary to fulfill their job duties. We also recommend using multi-factor authentication (MFA) with each account, requiring the use of SSL/TLS to communicate with AWS resources, setting up API/user activity logging with AWS CloudTrail, and using AWS encryption solutions, along with all default security controls within AWS Services. You can also use advanced managed security services, such as Amazon Macie, which assists in discovering and securing personal data stored in Amazon S3.
For more information, you can download the AWS Security Best Practices whitepaper or visit the AWS Security Resources or GDPR Center webpages. In addition to our solutions and services, AWS APN partners can provide hundreds of tools and features to help you meet your security objectives, ranging from network security and configuration management to access control and data encryption.
Attention, case modders: take a look at the Brutus 2, an extremely snazzy computer case with a partly transparent, animated side panel that’s powered by a Pi. Daniel Otto and Carsten Lehman have a current crowdfunder for the case; their video is in German, but the looks of the build speak for themselves. There are some truly gorgeous effects here.

What’s case modding?
Case modding just means modifying your computer or gaming console’s case, and it’s very popular in the gaming community. Some mods are functional, while others improve the way the case looks. Lots of dedicated gamers don’t only want a powerful computer, they also want it to look amazing — at home, or at LAN parties and games tournaments.
The Brutus 2 case
The Brutus 2 case is made by Daniel and Carsten’s startup, 3nb electronics, and it’s a product that is officially Powered by Raspberry Pi. Its standout feature is the semi-transparent TFT screen, which lets you play any video clip you choose while keeping your gaming hardware on display. It looks incredibly cool. All the graphics for the case’s screen are handled by a Raspberry Pi, so it doesn’t use any of your main PC’s GPU power and your gaming won’t suffer.
The software
To use Brutus 2, you just need to run a small desktop application on your PC to choose what you want to display on the case. A number of neat animations are included, and you can upload your own if you want.
So far, the app only runs on Windows, but 3nb electronics are planning to make the code open-source, so you can modify it for other operating systems, or to display other file types. This is true to the spirit of the case modding and Raspberry Pi communities, who love adapting, retrofitting, and overhauling projects and code to fit their needs.
Daniel and Carsten say that one of their campaign’s stretch goals is to implement more functionality in the Brutus 2 app. So in the future, the case could also show things like CPU temperature, gaming stats, and in-game messages. Of course, there’s nothing stopping you from integrating features like that yourself.
If you have any questions about the case, you can post them directly to Daniel and Carsten here.
The crowdfunding campaign
The Brutus 2 campaign on Startnext is currently halfway to its first funding goal of €10000, with over three weeks to go until it closes. If you’re quick, you still be may be able to snatch one of the early-bird offers. And if your whole guild NEEDS this, that’s OK — there are discounts for bulk orders.
Amazon Kinesis Data Firehose is the easiest way to capture and stream data into a data lake built on Amazon S3. This data can be anything—from AWS service logs like AWS CloudTrail log files, Amazon VPC Flow Logs, Application Load Balancer logs, and others. It can also be IoT events, game events, and much more. To efficiently query this data, a time-consuming ETL (extract, transform, and load) process is required to massage and convert the data to an optimal file format, which increases the time to insight. This situation is less than ideal, especially for real-time data that loses its value over time.
To solve this common challenge, Kinesis Data Firehose can now save data to Amazon S3 in Apache Parquet or Apache ORC format. These are optimized columnar formats that are highly recommended for best performance and cost-savings when querying data in S3. This feature directly benefits you if you use Amazon Athena, Amazon Redshift, AWS Glue, Amazon EMR, or any other big data tools that are available from the AWS Partner Network and through the open-source community.
Amazon Connect is a simple-to-use, cloud-based contact center service that makes it easy for any business to provide a great customer experience at a lower cost than common alternatives. Its open platform design enables easy integration with other systems. One of those systems is Amazon Kinesis—in particular, Kinesis Data Streams and Kinesis Data Firehose.
What’s really exciting is that you can now save events from Amazon Connect to S3 in Apache Parquet format. You can then perform analytics using Amazon Athena and Amazon Redshift Spectrum in real time, taking advantage of this key performance and cost optimization. Of course, Amazon Connect is only one example. This new capability opens the door for a great deal of opportunity, especially as organizations continue to build their data lakes.
Amazon Connect includes an array of analytics views in the Administrator dashboard. But you might want to run other types of analysis. In this post, I describe how to set up a data stream from Amazon Connect through Kinesis Data Streams and Kinesis Data Firehose and out to S3, and then perform analytics using Athena and Amazon Redshift Spectrum. I focus primarily on the Kinesis Data Firehose support for Parquet and its integration with the AWS Glue Data Catalog, Amazon Athena, and Amazon Redshift.
Solution overview
Here is how the solution is laid out:
The following sections walk you through each of these steps to set up the pipeline.
1. Define the schema
When Kinesis Data Firehose processes incoming events and converts the data to Parquet, it needs to know which schema to apply. The reason is that many times, incoming events contain all or some of the expected fields based on which values the producers are advertising. A typical process is to normalize the schema during a batch ETL job so that you end up with a consistent schema that can easily be understood and queried. Doing this introduces latency due to the nature of the batch process. To overcome this issue, Kinesis Data Firehose requires the schema to be defined in advance.
To see the available columns and structures, see Amazon Connect Agent Event Streams. For the purpose of simplicity, I opted to make all the columns of type String rather than create the nested structures. But you can definitely do that if you want.
The simplest way to define the schema is to create a table in the Amazon Athena console. Open the Athena console, and paste the following create table statement, substituting your own S3 bucket and prefix for where your event data will be stored. A Data Catalog database is a logical container that holds the different tables that you can create. The default database name shown here should already exist. If it doesn’t, you can create it or use another database that you’ve already created.
That’s all you have to do to prepare the schema for Kinesis Data Firehose.
2. Define the data streams
Next, you need to define the Kinesis data streams that will be used to stream the Amazon Connect events. Open the Kinesis Data Streams console and create two streams. You can configure them with only one shard each because you don’t have a lot of data right now.
3. Define the Kinesis Data Firehose delivery stream for Parquet
Let’s configure the Data Firehose delivery stream using the data stream as the source and Amazon S3 as the output. Start by opening the Kinesis Data Firehose console and creating a new data delivery stream. Give it a name, and associate it with the Kinesis data stream that you created in Step 2.
As shown in the following screenshot, enable Record format conversion (1) and choose Apache Parquet (2). As you can see, Apache ORC is also supported. Scroll down and provide the AWS Glue Data Catalog database name (3) and table names (4) that you created in Step 1. Choose Next.
To make things easier, the output S3 bucket and prefix fields are automatically populated using the values that you defined in the LOCATION parameter of the create table statement from Step 1. Pretty cool. Additionally, you have the option to save the raw events into another location as defined in the Source record S3 backup section. Don’t forget to add a trailing forward slash “ / “ so that Data Firehose creates the date partitions inside that prefix.
On the next page, in the S3 buffer conditions section, there is a note about configuring a large buffer size. The Parquet file format is highly efficient in how it stores and compresses data. Increasing the buffer size allows you to pack more rows into each output file, which is preferred and gives you the most benefit from Parquet.
Compression using Snappy is automatically enabled for both Parquet and ORC. You can modify the compression algorithm by using the Kinesis Data Firehose API and update the OutputFormatConfiguration.
Be sure to also enable Amazon CloudWatch Logs so that you can debug any issues that you might run into.
Lastly, finalize the creation of the Firehose delivery stream, and continue on to the next section.
4. Set up the Amazon Connect contact center
After setting up the Kinesis pipeline, you now need to set up a simple contact center in Amazon Connect. The Getting Started page provides clear instructions on how to set up your environment, acquire a phone number, and create an agent to accept calls.
After setting up the contact center, in the Amazon Connect console, choose your Instance Alias, and then choose Data Streaming. Under Agent Event, choose the Kinesis data stream that you created in Step 2, and then choose Save.
At this point, your pipeline is complete. Agent events from Amazon Connect are generated as agents go about their day. Events are sent via Kinesis Data Streams to Kinesis Data Firehose, which converts the event data from JSON to Parquet and stores it in S3. Athena and Amazon Redshift Spectrum can simply query the data without any additional work.
So let’s generate some data. Go back into the Administrator console for your Amazon Connect contact center, and create an agent to handle incoming calls. In this example, I creatively named mine Agent One. After it is created, Agent One can get to work and log into their console and set their availability to Available so that they are ready to receive calls.
To make the data a bit more interesting, I also created a second agent, Agent Two. I then made some incoming and outgoing calls and caused some failures to occur, so I now have enough data available to analyze.
5. Analyze the data with Athena
Let’s open the Athena console and run some queries. One thing you’ll notice is that when we created the schema for the dataset, we defined some of the fields as Strings even though in the documentation they were complex structures. The reason for doing that was simply to show some of the flexibility of Athena to be able to parse JSON data. However, you can define nested structures in your table schema so that Kinesis Data Firehose applies the appropriate schema to the Parquet file.
Let’s run the first query to see which agents have logged into the system.
The query might look complex, but it’s fairly straightforward:
WITH dataset AS (
SELECT
from_iso8601_timestamp(eventtimestamp) AS event_ts,
eventtype,
– CURRENT STATE
json_extract_scalar(
currentagentsnapshot,
'$.agentstatus.name') AS current_status,
from_iso8601_timestamp(
json_extract_scalar(
currentagentsnapshot,
'$.agentstatus.starttimestamp')) AS current_starttimestamp,
json_extract_scalar(
currentagentsnapshot,
'$.configuration.firstname') AS current_firstname,
json_extract_scalar(
currentagentsnapshot,
'$.configuration.lastname') AS current_lastname,
json_extract_scalar(
currentagentsnapshot,
'$.configuration.username') AS current_username,
json_extract_scalar(
currentagentsnapshot,
'$.configuration.routingprofile.defaultoutboundqueue.name') AS current_outboundqueue,
json_extract_scalar(
currentagentsnapshot,
'$.configuration.routingprofile.inboundqueues[0].name') as current_inboundqueue,
– PREVIOUS STATE
json_extract_scalar(
previousagentsnapshot,
'$.agentstatus.name') as prev_status,
from_iso8601_timestamp(
json_extract_scalar(
previousagentsnapshot,
'$.agentstatus.starttimestamp')) as prev_starttimestamp,
json_extract_scalar(
previousagentsnapshot,
'$.configuration.firstname') as prev_firstname,
json_extract_scalar(
previousagentsnapshot,
'$.configuration.lastname') as prev_lastname,
json_extract_scalar(
previousagentsnapshot,
'$.configuration.username') as prev_username,
json_extract_scalar(
previousagentsnapshot,
'$.configuration.routingprofile.defaultoutboundqueue.name') as current_outboundqueue,
json_extract_scalar(
previousagentsnapshot,
'$.configuration.routingprofile.inboundqueues[0].name') as prev_inboundqueue
from kfhconnectblog
where eventtype <> 'HEART_BEAT'
)
SELECT
current_status as status,
current_username as username,
event_ts
FROM dataset
WHERE eventtype = 'LOGIN' AND current_username <> ''
ORDER BY event_ts DESC
The query output looks something like this:
Here is another query that shows the sessions each of the agents engaged with. It tells us where they were incoming or outgoing, if they were completed, and where there were missed or failed calls.
WITH src AS (
SELECT
eventid,
json_extract_scalar(currentagentsnapshot, '$.configuration.username') as username,
cast(json_extract(currentagentsnapshot, '$.contacts') AS ARRAY(JSON)) as c,
cast(json_extract(previousagentsnapshot, '$.contacts') AS ARRAY(JSON)) as p
from kfhconnectblog
),
src2 AS (
SELECT *
FROM src CROSS JOIN UNNEST (c, p) AS contacts(c_item, p_item)
),
dataset AS (
SELECT
eventid,
username,
json_extract_scalar(c_item, '$.contactid') as c_contactid,
json_extract_scalar(c_item, '$.channel') as c_channel,
json_extract_scalar(c_item, '$.initiationmethod') as c_direction,
json_extract_scalar(c_item, '$.queue.name') as c_queue,
json_extract_scalar(c_item, '$.state') as c_state,
from_iso8601_timestamp(json_extract_scalar(c_item, '$.statestarttimestamp')) as c_ts,
json_extract_scalar(p_item, '$.contactid') as p_contactid,
json_extract_scalar(p_item, '$.channel') as p_channel,
json_extract_scalar(p_item, '$.initiationmethod') as p_direction,
json_extract_scalar(p_item, '$.queue.name') as p_queue,
json_extract_scalar(p_item, '$.state') as p_state,
from_iso8601_timestamp(json_extract_scalar(p_item, '$.statestarttimestamp')) as p_ts
FROM src2
)
SELECT
username,
c_channel as channel,
c_direction as direction,
p_state as prev_state,
c_state as current_state,
c_ts as current_ts,
c_contactid as id
FROM dataset
WHERE c_contactid = p_contactid
ORDER BY id DESC, current_ts ASC
The query output looks similar to the following:
6. Analyze the data with Amazon Redshift Spectrum
With Amazon Redshift Spectrum, you can query data directly in S3 using your existing Amazon Redshift data warehouse cluster. Because the data is already in Parquet format, Redshift Spectrum gets the same great benefits that Athena does.
Here is a simple query to show querying the same data from Amazon Redshift. Note that to do this, you need to first create an external schema in Amazon Redshift that points to the AWS Glue Data Catalog.
SELECT
eventtype,
json_extract_path_text(currentagentsnapshot,'agentstatus','name') AS current_status,
json_extract_path_text(currentagentsnapshot, 'configuration','firstname') AS current_firstname,
json_extract_path_text(currentagentsnapshot, 'configuration','lastname') AS current_lastname,
json_extract_path_text(
currentagentsnapshot,
'configuration','routingprofile','defaultoutboundqueue','name') AS current_outboundqueue,
FROM default_schema.kfhconnectblog
The following shows the query output:
Summary
In this post, I showed you how to use Kinesis Data Firehose to ingest and convert data to columnar file format, enabling real-time analysis using Athena and Amazon Redshift. This great feature enables a level of optimization in both cost and performance that you need when storing and analyzing large amounts of data. This feature is equally important if you are investing in building data lakes on AWS.
