Which of the following are pillars of the AWS Well-Architected Framework?

The AWS Well-Architected Framework is a set of six pillars and lenses that help cloud architects design and run workloads in the cloud. The six pillars are: operational excellence, security, reliability, performance efficiency, cost optimization, and sustainability. Each pillar has a set of design principles and best practices that guide the architectural decisions. High availability is not a separate pillar, but a quality that can be achieved by applying the principles of the reliability pillar. Going global in minutes and continuous development are not pillars of the framework, but possible benefits of using AWS services and following the framework’s recommendations. References: AWS Well-Architected - Build secure, efficient cloud applications, AWS Well-Architected Framework, The 6 Pillars of the AWS Well-Architected Framework
