A tool for reviewing workload architecture based on the AWS Well-Architected Framework

About 2 min read

What It Does

AWS Well-Architected Tool reviews workload architecture based on the six pillars of the AWS Well-Architected Framework (Operational Excellence, Security, Reliability, Performance Efficiency, Cost Optimization, and Sustainability) to identify improvements. Reviews are conducted by answering questions, and high-risk items with improvement recommendations are presented.

Use Cases

Architecture reviews of production environments, design validation for new workloads, periodic architecture health checks, and verifying compliance with AWS best practices.

Everyday Analogy

Think of a building seismic assessment. Following an expert checklist (Well-Architected Framework), the building (workload) is assessed and improvements are reported across areas like earthquake resistance (reliability), security (security), and energy efficiency (cost optimization).

What Is the Well-Architected Tool?

The AWS Well-Architected Tool is a self-service review tool based on the Well-Architected Framework - a collection of best practices AWS has systematized from years of experience. Register a workload, answer questions for each pillar, and high-risk issues (HRI) and medium-risk issues (MRI) are identified with specific improvement plans. It's free to use.

Six Pillars and Custom Lenses

The six pillars evaluate: Operations (automation, monitoring), Security (IAM, encryption), Reliability (disaster recovery, scaling), Performance (resource selection, optimization), Cost (waste elimination, pricing models), and Sustainability (environmental impact reduction). Beyond the official AWS lenses, specialized lenses (SaaS, Serverless) and custom organizational lenses can be created. For a comprehensive overview of the six pillars and custom lenses, specialized books on Amazon are a useful reference.

Getting Started

Define a workload in the Well-Architected Tool console, select a lens (AWS Well-Architected Framework), and start the review. Answer each question and high-risk items appear on the dashboard. Create improvement plans and track progress with milestones.

Things to Watch Out For

  • The Well-Architected Tool itself is free. Implementing improvements (adding/changing resources) incurs separate costs
  • AWS partner-led Well-Architected Reviews may qualify for AWS credits through partner programs
