Goal: Perform Well-Architected reviews throughout a workloads lifecycle
Target: For Tier1 workloads each stage has a full review, for Tier2 and below workloads the minimum requirement is: In the development stage review Security, Reliability and Operational Excellence. In Performance test review Performance Efficiency and Cost Optimization.
Why? When does it work well or not?: Ensures the correct level review is performed inline with organization requirements. It also allows for tradeoffs if the organization is prioritizing speed to market for some workloads.
Goal: Perform Well-Architected reviews regularly on active workloads
Target: Tier1 workloads will have milestones with all pillars completed at least every 3 months, for Tier2 workloads milestones with all pillars are completed at least every 6 months, all other workloads are to have milestones with all pillars completed yearly.
Measures: Number of milestones completed, number of teams delivering
Why? When does it work well or not?: Ensures workloads are actively maintained and inline with best practices. Will result in higher operational costs if there are minimal changes in the workload, and no additional services/features available.
Now that you have completed the lab, if you have implemented this knowledge in your organization,
you should complete a milestone in the Well-Architected tool. This lab specifically helps you with
