AWS Trusted Advisor is a new component introduced into the AWS Management Console that analyzes usage across services and provides best practice recommendations for optimization. It offers four core checks to help customers optimize their cost, performance, security, and fault tolerance. The integration of AWS Trusted Advisor with Datadog allows users to monitor resource consumption data in real-time, providing actionable insight into their AWS infrastructure. This integration enables users to quickly see how custom optimization recommendations from Trusted Advisor affect their resource allocation and consumption, making it easier to scale their AWS environment. With this setup, users can set up custom monitors and alerts within Datadog to gain more precise control over their services' resource consumption, ultimately improving their AWS performance and usage management.
