The AWS Well-Architected Framework

Architectural Guardrails for Secure, High-Performing, and Efficient Cloud Systems

The Six Pillars

1. Operational Excellence

Run, Monitor, and Improve

Focuses on running and monitoring systems. Key: Operations as Code and Frequent, Small, Reversible changes.

2. Security

Protect Data and Systems

Focuses on asset protection. Key: Strong identity foundation, Security at all layers, and Data Protection.

3. Reliability

Stay Up and Recover

Workload functional correctness. Key: Automatic recovery from failure and Horizontal scaling.

4. Performance Efficiency

Resource Optimization

Efficiency in computing resource usage. Key: Serverless architectures and Going Global in minutes.

5. Cost Optimization

Eliminate Waste

Avoiding unnecessary costs. Key: Consumption model and Measuring overall efficiency.

6. Sustainability

Environmental Impact

Environmental impact reduction. Key: Maximize utilization and selecting energy-efficient regions.

General Design Principles

Stop Guessing Capacity: Use Auto-Scaling to match demand.

Test Systems at Scale: Create production-scale test environments.

Automate Testing: Use IaC to replicate environments effortlessly.

Evolutionary Architectures: Adopt new technologies as they evolve.

Data-Driven Decisions: Use real metrics to inform design.

Improve Through Game Days: Simulate failures regularly.
