Chase is planning for a significant workload migration of its systems to Amazon Web Services (AWS) over the coming years.
We have the opportunity to not only take advantage of the modern infrastructure with cloud, but also to design well-architected systems once we modernize our applications. But to achieve success with an AWS system and take full advantage of the processes to deliver software to AWS, we will have to align core concepts and definitions with the industry best practices. In this three-part series, I’ll focus on the availability concept of resiliency and the testing of availability through chaos experiments, then discuss how to establish availability requirements and add them to the deployment module in SEAL.
AWS Well-Architected and the Reliability Pillar
AWS Well-Architected helps cloud architects build secure, high-performing, resilient and efficient infrastructure for a variety of applications and workloads. Built around six pillars — operational excellence, security, reliability, performance efficiency, cost optimization and sustainability — AWS Well-Architected provides a consistent approach for customers and partners to evaluate architectures and implement scalable designs.
