AWS Trusted Advisor will help to optimize your AWS environment by reducing cost, increasing performance, and improving security. It provides real-time guidance to help you provision resources according to AWS Best Practices guidelines.

AWS Infrastructure Optimization

This service provides best practice recommendations in 5 categories:

Cost Optimization: save money by eliminating unused/idle resources or using reserved capacity
Fault Tolerance: increase availability and redundancy by using auto scaling, health checks, multi AZ, and backup
Performance: check service limits, ensure you’re taking advantage of provisioned throughput, and monitor over-utilized instances
Service Limits: checks for service limits >80% of service limit
Security: close gaps by enabling security features and examining permissions

The status check is shown by 3 colors: green (no problem), yellow (investigation recommended), and red (action recommended).
