Service: AWS Well-Architected Tool
Answer:
The AWS Well-Architected Tool is a service provided by AWS that allows customers to review their workloads against the best practices for the AWS architecture. It helps customers to understand the state of their workloads and identify areas for improvement, such as performance, security, cost, and reliability.
The Well-Architected Tool provides a framework of five pillars that are considered key to building and operating well-architected systems on AWS. These pillars are:
Operational excellence: focuses on the ability to run and monitor systems to deliver business value and to continually improve supporting processes and procedures.
Security: focuses on protecting information and systems.
Reliability: focuses on ensuring a workload operates correctly and consistently, recovering from infrastructure or service disruptions, and mitigating disruptions.
Performance efficiency: focuses on using computing resources efficiently to meet system requirements and to maintain that efficiency as demand changes and technologies evolve.
Cost optimization: focuses on avoiding unnecessary costs.
The AWS Well-Architected Tool provides a questionnaire that customers can use to evaluate their workloads against these pillars. The tool provides guidance and best practices to improve each area and helps customers prioritize recommendations based on their business needs. The tool also provides a mechanism for tracking progress over time and for reviewing new workloads as they are developed.
