AWS Well-Architected

Learn, measure, and build using architectural best practices

AWS Well-Architected helps cloud architects build secure, high-performing, resilient, and efficient infrastructure for their applications and workloads. Based on five pillars — operational excellence, security, reliability, performance efficiency, and cost optimization — AWS Well-Architected provides a consistent approach for customers and partners to evaluate architectures, and implement designs that can scale over time.

The AWS Well-Architected Framework started as a single whitepaper but has expanded to include domain-specific lenses, hands-on labs, and the AWS Well-Architected Tool. The AWS WA Tool, available at no cost in the AWS Management Console, provides a mechanism for regularly evaluating your workloads, identifying high risk issues, and recording your improvements.  

AWS has an ecosystem of hundreds of members of the Well-Architected Partner Program. Engage a partner in your area to help you analyze and review your applications.

Coming soon, a new AWS Well-Architected Management and Governance Lens to help enterprise customers innovate faster and maintain control over cost, compliance, and security. With AWS, customers can achieve visibility and operations at scale across resources, data, and applications in a dynamic cloud environment. Read more about the upcoming AWS Well-Architected Management and Governance Lens.

AWS Well-Architected and the Five Pillars

Framework Overview

The AWS Well-Architected Framework describes the key concepts, design principles, and architectural best practices for designing and running workloads in the cloud. By answering a set of foundational questions, you learn how well your architecture aligns with cloud best practices and are provided guidance for making improvements.

Operational Excellence Pillar

The operational excellence pillar focuses on running and monitoring systems to deliver business value, and continually improving processes and procedures. Key topics include automating changes, responding to events, and defining standards to manage daily operations.

Security Pillar

The security pillar focuses on protecting information and systems. Key topics include confidentiality and integrity of data, identifying and managing who can do what with privilege management, protecting systems, and establishing controls to detect security events.

Reliability Pillar

The reliability pillar focuses on ensuring a workload performs its intended function correctly and consistently when it’s expected to. A resilient workload quickly recovers from failures to meet business and customer demand. Key topics include distributed system design, recovery planning, and how to handle change.

Performance Efficiency Pillar

The performance efficiency pillar focuses on using IT and computing resources efficiently. Key topics include selecting the right resource types and sizes based on workload requirements, monitoring performance, and making informed decisions to maintain efficiency as business needs evolve.

Cost Optimization Pillar

The cost optimization pillar focuses on avoiding unnecessary costs. Key topics include understanding and controlling where money is being spent, selecting the most appropriate and right number of resource types, analyzing spend over time, and scaling to meet business needs without overspending.

AWS Well-Architected Lenses

Lenses extend the guidance offered by AWS Well-Architected to specific industry and technology domains, such as machine learning, analytics, serverless, high performance computing (HPC), IoT (Internet of Things), and financial services. To fully evaluate your workloads, use applicable lenses together with the AWS Well-Architected Framework and the five pillars.
