In 2012, we published the first version of the Framework. In 2015, we released the AWS Well-Architected Framework whitepaper. We added the Operational Excellence pillar in 2016. We released the pillar-specific whitepapers and AWS Well-Architected Lenses in 2017. The following year, the AWS Well-Architected Tool was launched.

In 2020, we released the new version of the Well-Architected Framework guidance, more lenses, and an API integration with the AWS Well-Architected Tool. We added the sixth pillar, Sustainability in 2021. In 2022, dedicated pages were introduced for each consolidated best practices across all six pillars, with several best practices updated with improved prescriptive guidance. By December 2023, we improved more than 75% of the Framework’s best practices. As of November 2024, we’ve refreshed 100% of the Framework’s best practices at least once since October 2022.

What’s new

The Well-Architected Framework supports customers as they mature in their cloud journey by providing guidance to help achieve more operable, secure, sustainable, scalable, and resilient environment and workload solutions.

What’s new

Updates to the Well-Architected content include:

Learn, measure, improve, and iterate

Best practices include regularly reviewing your workloads—even those that have not had major changes. We encourage you to assess your existing workloads as your architecture evolves or business needs change, and create milestones for your workloads as they develop. Use the Well-Architected Framework to guide your design and architecture of new workloads, or of workloads that you are planning on moving to the cloud.

Taking best practices into account early in your process can yield high success rates. In effective organizations, each best practice is considered and prioritized with respect to the goal they are trying to achieve.

AWS Well-Architected helps cloud architects build secure, high-performing, resilient, and efficient infrastructure for a variety of applications and workloads. The Framework is built around six pillars—operational excellence, security, reliability, performance efficiency, cost optimization, and sustainability.

The AWS Well-Architected Framework provides you with a formal approach to compare your workloads against best practices. It also includes guidance on how to make improvements.

Machine learning (ML) algorithms discover and learn patterns in data, and construct mathematical models to predict future data. These solutions can revolutionize lives through better diagnoses of diseases, environmental protections, products and services transformation, and more.

Your ML models depend on the quality of input data to generate accurate results. As data changes over time, monitoring is required to continuously detect, correct, and mitigate issues. This improves accuracy and performance. It also may require you to retrain your model with the latest refined data.

Application workloads rely on step-by-step instructions to solve a problem. ML workloads enable algorithms to learn from data through an iterative and continuous cycle. We are announcing a brand-new version of the AWS Well-Architected Machine Learning Lens whitepaper. It complements and builds upon the Well-Architected Framework to address this difference between these two types of workloads.

The whitepaper provides you with a set of established cloud and technology agnostic best practices. You can apply this guidance and architectural principles when designing your ML workloads, or after your workloads have entered production as part of continuous improvement. The paper includes guidance and resources to help you implement these best practices on AWS.

The Well-Architected Machine Learning Lens components

The Lens includes four focus areas:

1. The Well-Architected Machine Learning Design Principles — A set of considerations that are used as the basis for a Well-Architected ML workload. These design principles are the guiding light for the collection of the best practices in the ML Lens.

2. The Well-Architected Machine Learning Lifecycle — This integrates the Well-Architected Framework into the Machine Learning Lifecycle as can be seen in figure 1.

    • The Well-Architected Framework pillars includes:
      1. Operational Excellence
      2. Security
      3. Reliability
      4. Performance Efficiency
      5. Cost Optimization
    • The Machine Learning Lifecycle phases referenced in the ML Lens include:
      1. Business goal identification
      2. ML problem framing
      3. Data processing (data collection, data pre-processing, feature engineering)
      4. Model development (training, tuning, evaluation)
      5. Model deployment (prediction, inference)
      6. Model monitoring

In the Well-Architected ML Lens whitepaper, the Well-Architected Machine Learning Lifecycle applies the Well-Architected Framework pillars to each of the lifecycle phases.

3. Cloud and technology agnostic best practices — These are best practices for each ML lifecycle phase across the Well-Architected Framework pillars. Best practices are accompanied by:

    • Implementation guidance that provides AWS implementation plans for each best practice with references to AWS technologies and resources.
    • Resources as a set of links to AWS documents, blogs, videos, and code examples as supporting resources to the best practices and their implementation plans.

4. ML Lifecycle architecture diagrams — These illustrate processes, technologies, and components that support many of the best practices, shown in Figure 2. They include: Feature stores, Model Registry, lineage tracker, alarm manager, scheduler, and more. Different pipeline technologies are illustrated using these architecture diagrams.

Where should you apply the Well-Architected Machine Learning Lens?

Use the Well-Architected ML Lens to:

  • Make informed decisions — Plan early and make informed decisions by reviewing best practices before a new workload design begins.
  • Build and deploy faster — Use the best practices to guide you through building new Well-Architected workloads across the ML lifecycle.
  • Lower or mitigate risks — Evaluate existing workloads regularly to identify, mitigate, and address potential issues early.
  • Learn AWS best practices — Use the provided implementation plans as guidance on implementing the best practices on AWS.

Conclusion

The new Well-Architected Machine Learning Lens whitepaper is available now. Use the Lens to help ensure that your ML workloads are architected with operational excellence, security, reliability, performance efficiency, and cost optimization in mind.
