Reserved Instances are suitable for stateful workloads that have predictable and consistent usage patterns for a long-term period. By committing to a one-year or three-year term, customers can reduce their total cost of ownership and optimize their cloud spend. Reserved Instances also provide capacity reservation, ensuring that customers have access to the EC2 instances they need when they need them. References: AWS Pricing Calculator, Amazon EC2 Pricing, [AWS Cloud Practitioner Essentials: Module 3 - Compute in the Cloud]

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
