Summary

Previously on Mobycast...
In episodes #78 and #79, we broke down the AWS Well-Architected Framework, and covered the first three pillars of excellence: "Operational Excellence", "Security" and "Reliability".
This week on Mobycast, Jon and Chris wrap up their three-part series and discuss the last two pillars of excellence, "Performance Efficiency" and "Cost Optimization". We then bring it all together by explaining how to perform a Well-Architected Review. Spoiler alert: the Well-Architected Tool is a fabulous resource that you need to have in your toolkit.

  • The Well-Architected Review
    • Centered around the question "Are you well architected?"
    • The Well-Architected review provides a consistent approach to review workload against current AWS best practices and gives advice on how to architect for the cloud
    • Benefits of the review
      • Build and deploy faster
      • Lower or mitigate risks
      • Make informed decisions
      • Learn AWS best practices
  • The AWS Well-Architected Tool
    • Cloud-based service available from the AWS console
    • Provides consistent process for you to review and measure your architecture using the AWS Well-Architected Framework
    • Helps you:
      • Learn
      • Measure
      • Improve
    • Improvement plan
      • Based on identified high and medium risk topics
      • Canned list of suggested action items to address each risk topic
    • Milestones
      • Makes a read-only snapshot of completed questions and answers
    • Best practices
      • Save milestone after initially completing workload review
      • Then, whenever you make large changes to your workload architecture, perform a subsequent review and save as a new milestone
