On the 29th November 2018, Amazon introduced the Well-Architected tool. With the help of this tool, AWS users can access their planned architectures vis-a-vis the latest AWS architecture best practices. In addition, AWS users can get guidance on improving their present application architectures. This tool is based on the increasingly popular Well-Architected framework which helps users build secure, high performance, resilient, and efficient AWS-based solutions. This tool provides a consistent approach for users to evaluate planned and existing architectures and provides guidance to help implement designs that scale in accordance with application needs.
Importantly, with the help of this tool users get insights on potential security risks and identify steps to address these risks via the Well-Architected framework. The tool guides the user through a series of question and answers covering different aspects of the five pillars of the AWS Well-Architected framework (namely, operational excellence, security, reliability, performance efficiency, and cost optimization) and at the end gives you a set of recommendations for the architecture. The Well-Architected tool is freely available to all users but is only available in US East (N. Virginia), US East (Ohio), US West (Oregon), and Europe (Ireland).
