As businesses increasingly migrate their applications and infrastructure to the cloud, ensuring resiliency becomes paramount to maintain service availability and minimize disruptions. Resilient cloud architectures are designed to withstand failures and recover quickly from disruptions, offering enhanced reliability and performance. This article provides an overview of resiliency patterns and trade-offs that can help architects build efficient and robust cloud solutions.

‍The Reliability pillar of the AWS Well-Architected Framework focuses on designing and operating reliable and resilient systems in the cloud. It involves building systems that can automatically recover from failures, scale to meet changing demands and maintain availability in the face of disruptions. The Reliability pillar also emphasizes the importance of testing, monitoring, and continuously improving systems to ensure they meet the needs of the organization.
