Announcing updates to the AWS Well-Architected Framework

We are pleased to announce the availability of improvements Well-Architected AWS Framework advice. In this update, we have made changes to the six pillars of the framework: Operational Excellence, Security, Reliability, Performance efficiency, Cost optimizationAnd Sustainability.

A short story

The AWS Well-Architected Framework is a set of best practices that enable customers to assess and improve the design, implementation, and operations of their cloud workloads.

In 2012, the first version of the framework was published, leading to the publication in 2015 of the guidance white paper. We added the operational excellence pillar in 2016. The Pillar-specific white papers And Well-Architected AWS Goals were released in 2017, and the following year the Well-Architected AWS Tool Was launched.

In 2020, Well-Architected Framework content received a major update, as well as other insights and API integration with the AWS Well-Architected tool. The sixth pillar, sustainability, was added in 2021. In 2022, dedicated pages were introduced for each consolidated best practice across the six pillars, with several updated best practices with improved prescriptive guidelines.

Well-Architected AWS Timeline

What’s new

Well-Architected Framework content is constantly updated and enhanced to adapt to the ever-changing and innovative AWS environment, with new and advanced emerging services and technologies. This ensures cloud architects can build and operate secure, high-performing, resilient, efficient, and sustainable systems in the AWS Cloud.

Content updates and enhancements in this release aim to provide more comprehensive coverage across the entire AWS service portfolio to help customers make more informed decisions when developing implementation plans. Services that have been added or expanded in coverage include: AWS Elastic Disaster Recovery, AWS Trusted Advisor, AWS Resilience Center, AWS Setup, AWS Security Center, Amazon GuardDuty, AWS Organizations, AWS Control Tower, AWS Compute Optimizer, AWS budgets, Amazon CodeWhispererAnd Amazon Code Guru.

Pillar Updates

The Operational Excellence Pillar has a new best practice on enabling support plans for production workloads. This Pillar also takes stock of the definition of a customer communication plan in the event of unavailability.

In the Security pillar, we added a new best practice area, Application Security (AppSec). AppSec is complete with eight new best practices to guide customers as they develop, test, and release software, providing guidance on how to review the tools, testing, and organizational approach used to develop software.

The Reliability Pillar has a new best practice on architecting workloads to achieve availability goals and availability service level agreements (SLAs). We have also added the Resilience Shared Responsibility Model to its introductory section.

The Cost Optimization pillar offers new best practices for automating operations in cost optimization efforts and enforcement of data retention policies.

In the Sustainability pillar, we introduced a clear region selection process, as well as tools to properly size services and improve overall resource utilization in the AWS Cloud.

Best practice updates

Implementation guidance and best practices have been updated in this release to be more prescriptive, including enhanced recommendations and steps on reusable architecture patterns targeting specific business outcomes in the AWS Cloud.

No fewer than 113 best practices are updated with more prescriptive guidance on operational excellence (22), security (18), reliability (14), performance efficiency (10), optimization of costs (22) and sustainability (27). Fourteen new best practices were introduced in operational excellence (1), safety (9), reliability (1), cost optimization (2) and sustainability (1).

Of a total of 127 new/updated best practices, 78% include explicit implementation steps to make them more prescriptive. The remaining 22% have been updated by improving their existing implementation steps. These changes are in addition to the 51 improved best practices published in 2022 (18 in Q3 2022and 33 in Q4 2022), resulting in more than 50% of the framework’s existing best practices being updated recently.
