Abstract
This paper describes the AWS Well-Architected Framework, which
enables customers to review and improve their cloud-based architectures and
better understand the business impact of their design decisions. We address
general design principles as well as specific best practices and guidance in five
conceptual areas that we define as the pillars of the Well-Architected
Framework.
