AWS Trusted Advisor

• AWS Trusted Advisor is an online tool that provides real-time guidance to help you provision your resources following AWS best practices.

• AWS Trusted Advisor looks at your entire AWS environment and gives you recommendations in five categories:

1. Cost Optimization

• AWS Trusted Advisor looks at your resource use and makes recommendations to help you optimize cost by eliminating unused and idle resources, or by making commitments to reserved capacity.

2. Performance

• Improve the performance of your service by checking your service limits, ensuring you take advantage of provisioned throughput, and monitoring for overutilized instances.

3. Security

• Improve the security of your application by closing gaps, enabling various AWS security features, and examining your permissions.

4. Fault Tolerance

• Increase the availability and redundancy of your AWS application by taking advantage of automatic scaling, health checks, Multi-AZ deployments, and backup capabilities.

5. Service Limits

• AWS Trusted Advisor checks for service usage that is more than 80 percent of the service limit. Values are based on a snapshot, so your current usage might differ.
• Limit and usage data can take up to 24 hours to reflect any changes.
