Understanding the AWS Well-Architected Review and Its Benefits

For organizations leveraging Amazon Web Services (AWS), a Well-Architected Review can be a game-changer. But what exactly is it, and why should your company consider one?

This blog presents the perspective of a cloud infrastructure expert.

The AWS Well-Architected Review (WAR) is a systematic approach provided by Amazon Web Services to help organizations evaluate and improve the architecture of their cloud workloads. This framework lays out a comprehensive set of best practices for designing and running secure, reliable, efficient, and cost-effective workloads on AWS.

This review is based on best practices across six key pillars: Security, Reliability, Performance Efficiency, Cost Optimization, Operational Excellence, and Sustainability.

  • Security: Ensuring your cloud environment is protected from unauthorized access.
  • Reliability: Building fault-tolerant systems that can withstand disruptions.
  • Performance Efficiency: Optimizing your architecture for speed and responsiveness.
  • Cost Optimization: Identifying opportunities to reduce your cloud spending.
  • Operational Excellence: Streamlining processes for managing and deploying your applications.
  • Sustainability: Optimizing workloads to meet your sustainability targets.

On top of the six areas mentioned above, AWS also allows to extend the review process with optional Lenses. Example focus areas include Serverless, SAP workloads, Healthcare sector, Machine Learning or Migration. Lenses provide a way to consistently measure architectures against best practices and identify areas for improvement in a specific area.

The review itself is conducted by qualified reviewers who examine your architecture against the six pillars of the Well-Architected Framework. AWS solutions architects or certified AWS partners conduct the review, which typically includes the following steps:

  1. Preparation: Gather information about your workload, including its architecture, deployment, and operational practices.
  2. Review Sessions: Conduct detailed discussions with your team to understand how your workload aligns with the Well-Architected Framework.
  3. Identify Issues: Highlight areas where your architecture deviates from best practices and identify potential risks and inefficiencies.
  4. Recommendations: Provide actionable recommendations to address identified issues and improve your cloud architecture.


By undergoing a Well-Architected Review, your organization gains valuable insights into your workload and its operating environment. If you commit to fixing at least 45% of the High findings identified with your WAR partner, AWS will also credit your account up to $5000. 

In conclusion, the AWS Well-Architected Review is a valuable exercise that enables organizations to build and maintain high-quality cloud architectures. An AWS Well-Architected Review is an investment in the future of your cloud infrastructure. By proactively identifying and addressing potential issues, you can ensure your cloud environment is secure, reliable, efficient, and cost-effective, allowing your organization to focus on what matters most – achieving your business goals.
