The AWS Well-Architected Framework helps cloud architects build the most secure, high-performing, resilient, and efficient infrastructure possible for their applications. This pillar covers the operations processes that keep an application running in production. In an on-premises environment, these requirements can cause long lead times due to dependencies and therefore must be incorporated during initial planning. The WAF Operational Excellence Pillar The OPS and the Security pillar (SEC) form the core of the AWS Well-Architected framework. © 2020, Amazon Web Services, Inc. or its affiliates. Control access to the Azure resources that you deploy. Think about security throughout the entire lifecycle of an application, from design and implementation to deployment and operations. Consider storing application secrets in Azure Key Vault. A reliable workload is one that is both resilient and available. But each VM in the pool must be able to handle any client request, so the application must be stateless or store state externally (say, in a distributed cache). Everything continues to change—your business context, business priorities, customer needs, etc. It’s important to design operations to support evolution over time in response to change and to incorporate lessons learned through their performance. If the foundation is not solid, structural problems can undermine the integrity and function of the building. Monitoring and diagnostics are crucial. Generating the raw data, from application logs, web server logs, diagnostics built into the Azure platform, and other sources. For example, you must have sufficient network bandwidth to your data center. We believe that having well-architected workloads greatly increases the likelihood of business success. This might lead to over-provisioned and under-optimized deployments.
