What are the five pillars of the AWS Well-Architected Framework?

The five pillars of the AWS Well-Architected Framework are Operational Excellence, Security, Reliability, Performance Efficiency, and Cost Optimization. This framework was designed to help architects build secure, high-performing, resilient, and efficient infrastructure for their applications while managing costs.

Operational Excellence focuses on operations in the cloud, including monitoring, incident response, and continuous improvement processes. Security ensures that a system is protected against risks by managing access, data protection, and incident response strategies. Reliability emphasizes the system's ability to recover from failures and maintain availability. Performance Efficiency deals with using resources efficiently to meet system requirements while adapting to changing demands. Cost Optimization involves controlling where the money is spent, ensuring that resources are allocated appropriately to minimize costs.

Understanding these pillars is crucial for designing cloud solutions that meet both business and technical requirements, ultimately leading to a well-architected environment that can adapt over time. The other choices listed may contain relevant concepts in cloud design but do not align with the established five pillars of the AWS Well-Architected Framework.
