Well-Architected Tool review discrepancies.

If you're experiencing discrepancies in the results or recommendations provided by the AWS Well-Architected Tool, here are some common causes and steps to address them:

1. Incomplete or Outdated Data:
   • Cause: The results of the Well-Architected Tool are based on the data provided at the time of the review. If the data is incomplete or outdated, it can lead to discrepancies.
   • Solution: Ensure that you provide accurate and up-to-date information about your architecture, workloads, and configurations during the review.
2. Misconfiguration or Misunderstanding:
   • Cause: Misconfigurations or misunderstandings about AWS services and best practices can lead to discrepancies in the recommendations.
   • Solution: Review the recommendations carefully and cross-check them with AWS best practices and documentation to ensure they align with your architecture.
3. Customized Questions and Answers:
   • Cause: The Well-Architected Tool allows for customization of questions and answers. If these customizations are not aligned with AWS best practices, it can lead to discrepancies.
   • Solution: Review the customizations made to questions and answers to ensure they accurately reflect your architecture and align with best practices.
4. Changing Architectural Patterns:
   • Cause: Architectural patterns and best practices evolve over time. If your architecture has recently undergone changes, it may not align with previous recommendations.
   • Solution: Regularly review and update your architecture to align with the latest AWS best practices and architectural patterns.
5. External Factors or Compliance Requirements:
   • Cause: External factors or compliance requirements specific to your organization may lead to variations in the recommendations provided by the Well-Architected Tool.
   • Solution: Consider any specific compliance requirements or constraints that may impact the recommendations, and ensure they are taken into account during the review.
6. Lack of Optimization Opportunities:
   • Cause: In some cases, your architecture may already be well-optimized, leading to fewer optimization recommendations from the tool.
   • Solution: Consider that a lower number of recommendations may indicate that your architecture is already well-optimized.
7. Review Customizations and Annotations:
   • Solution: Review any customizations or annotations made during the review process to ensure they accurately reflect your architecture and any additional context provided.
8. Seek Guidance from AWS Experts:
   • Solution: If you're unsure about specific recommendations, consider engaging with AWS Solution Architects or contacting AWS Support for additional guidance.
9. Regularly Reevaluate:
   • Solution: Perform regular reviews using the Well-Architected Tool to ensure that your architecture continues to align with best practices and recommendations.
10. Feedback and Documentation:
    • Solution: Provide feedback on any discrepancies you encounter with AWS. Additionally, document any unique architectural considerations or constraints that may impact the recommendations.

Remember to document any specific discrepancies or issues you encounter during the review process, as this information can be valuable in understanding and addressing the discrepancies.
