Cloud Concepts
AWS Well-Architected Framework
A framework for evaluating cloud workloads through six complementary pillars rather than a single architecture checklist.
Key points
- The pillars are operational excellence, security, reliability, performance efficiency, cost optimization, and sustainability.
- A design choice can affect several pillars, so improvement is about informed trade-offs.
- The framework teaches principles; the AWS Well-Architected Tool supports structured workload reviews.
Best-known use cases
- Identify which pillar matches a stated design concern.
- Use the pillars to discuss trade-offs and improvement priorities.
What candidates often confuse it with
- Reliability covers recovery and continued operation; operational excellence covers running and improving workloads.
- Performance efficiency selects and evolves resource use; cost optimization avoids unnecessary cost.
- Sustainability reduces environmental impact; it is not a synonym for reliability.
Key Cloud Practitioner takeaway
Match the concern in the scenario to the pillar definition, not to a product name.
