The AWS Well-Architected Framework is based on five pillars — operationalexcellence, security, reliability, performance efficiency, and cost optimization.

In AWS Well-Architected Framework, we also may use the following terms:

  1. Component is the code, configuration and AWS resources that together deliver against a requirement. A component is often the unit of technical ownership, and is decoupled from other components
  2. Workload to identify a set of components that together deliver business values. The workload is usually the level of detail that business and technology leaders communicate about.
  3. Milestones mark key changes in your architect as it evolves thru the product lifecycle (design, teseting, go live, and in production)
  4. Architect how components work together in a workload. How components communicate and interact is often the focus of architecture diagrams
  5. Technology Portfolio is the collection of workloads that are required for the business to operate.

When architecting workloads you make trade-offs between pillars based on your business context. For example:

  • You might reduce cost at the expense of reliability in dev environment.
  • For mission critical solutions, you might optimize reliability with increased costs.
  • In ecommerce solutions, performance can effect revenue and customer propensity to buy.

Security and Operational excellence are generally not trade-off against the other pillars.
