AWS Well-Architected Tool

Concept

AWS Well-Architected Tool uses questions and answers to check whether your system follows AWS’s good design principles. These principles are divided into several pillars of the AWS Well-Architected Framework: operations, security, reliability, performance, cost and sustainability. In the tool, you add your system as a workload and answer questions. Based on the answers, it identifies the risks and gives an improvement plan. With lenses, you can add extra questions for specific kinds of systems, such as serverless.

Simple example

An inspection with an engineer’s checklist after building a house — checking that the foundation, electricity and fire safety are all fine.

Why it’s needed

While building a system, some aspect of security, cost or reliability can be missed.

Where it’s used

Reviewing a system’s design, listing risks and making an improvement plan.
