AWS Trusted Advisor Overview
Trusted Advisor is a service that provides recommendations to optimize your AWS account, aligning with AWS best practices. It's a service that operates across multiple regions. Trusted Advisor offers insights in four primary categories:
Cost Optimization: Suggests how to restructure resources to reduce expenses.
Performance: Identifies potential performance bottlenecks.
Security: Scans for vulnerabilities or weak security configurations.
Fault Tolerance: Recommends practices to enhance service resilience and fault tolerance.
The comprehensive features of Trusted Advisor are exclusively accessible with AWS business or enterprise support plans. Without these plans, access is limited to six core checks, primarily focused on performance and security.

Data is refreshed every 24 hours. However, a manual refresh is possible 5 minutes after the last refresh.
