  • Addressing redundancy shortcomings
  • Identifying overused resources
  • Flagging potential service limits

Service Limits

Displays your current usage limits for AWS services and resources.
Use Cases:
  • Monitoring current usage against AWS service limits

Security

Specific Optimizations and Checks

Trusted Advisor provides detailed checks for various resource types to offer actionable recommendations.

AWS Trusted Advisor provides a cost optimization check that specifically identifies unattached and underutilized EBS volumes within your AWS environment. These volumes, while not actively used, can still incur storage costs. By flagging these resources, Trusted Advisor helps you reduce unnecessary expenses by either deleting or repurposing them.

Scope and Limitations

Understanding what Trusted Advisor primarily focuses on, and what it does not, is crucial for effective cloud governance.

The categories that AWS Trusted Advisor does not primarily focus on, compared to the given options, is Policy Compliance. While AWS Trusted Advisor can indirectly help improve your security posture and adherence to some best practices that could align with certain policies, it's not designed to specifically check or enforce adherence to regulatory compliance policies like PCI DSS or HIPAA.
Other AWS services like AWS Config and AWS Security Hub are more focused on compliance and governance.
