Building reliable architectures

Reliability is a critical pillar within the Well-Architected Framework for building robust workloads on AWS. It refers to a system’s ability to perform its intended function correctly and consistently whenever called upon. To put it simply, a reliable system is one you can count on to work as intended when needed. Reliability encompasses the entire lifecycle of a workload, from initial design through deployment and operations, until decommissioning. A reliable system should operate without failure throughout its lifespan. This guidance will provide in-depth, best-practice recommendations for architects and engineers on how to build workloads that adhere to the Reliability pillar’s principles and practices. Following AWS’s reliability tenets allows organizations to create resilient workloads that meet customer expectations, prevent business disruptions, and avoid the costs of system outages. Reliability is foundational to operational...
