AWS Trusted Advisor is a service that helps customers optimize their AWS infrastructure, increase performance, and reduce costs. It provides best practices and recommendations based on AWS usage and customer account activity.
Trusted Advisor offers several checks in categories such as cost optimization, performance, security, fault tolerance, and service limits. Each check includes recommendations, severity levels, and instructions for resolving issues.
Here are some examples of Trusted Advisor checks:
Cost Optimization: Identifies opportunities to save costs on AWS usage, such as unused or idle resources, underutilized instances, and non-optimized load balancers.
Performance: Analyzes AWS resources for potential performance bottlenecks, such as high CPU usage, high network usage, and EBS volume queue length.
Security: Evaluates security-related configurations for AWS services, such as IAM user activity, S3 bucket policies, and VPC security groups.
Fault Tolerance: Helps ensure that AWS resources are resilient to failures, by checking for instance redundancy, load balancer configurations, and RDS multi-AZ deployments.
Service Limits: Monitors usage of AWS services and checks for limits, such as EC2 instance limits, VPC limits, and EBS volume limits.
Trusted Advisor can be accessed through the AWS Management Console or through APIs. It is available for free to all AWS customers with Business or Enterprise support plans. Additional checks and features are available for customers with Enterprise support plans.
Overall, AWS Trusted Advisor is a powerful tool for optimizing AWS infrastructure, improving performance, and reducing costs. It helps customers identify potential issues and provides guidance for resolving them, leading to a more efficient and cost-effective AWS environment.
