Think of it as your personal cloud consultant that continuously analyzes your AWS infrastructure and offers recommendations to improve your cloud experience.
For Cost Optimization, Trusted Advisor identifies underutilized resources, idle load balancers, and unassociated Elastic IP addresses that could be eliminated to reduce spending. It helps you right-size your resources by recommending appropriate instance types based on actual usage patterns.
In the Security category, it checks for vulnerabilities such as unrestricted access to security groups, missing MFA on root accounts, exposed access keys, and S3 bucket permissions that might leave your data vulnerable.
Performance checks examine your service configurations to ensure optimal throughput and responsiveness. This includes analyzing EC2 instance utilization and CloudFront configuration optimizations.
Fault Tolerance recommendations focus on improving the reliability and redundancy of your applications by checking for things like RDS backups, Multi-AZ deployments, and Auto Scaling group configurations.
Service Limits monitoring alerts you when you approach AWS service quotas, helping prevent unexpected service interruptions.
The availability of Trusted Advisor checks depends on your AWS Support plan. Basic and Developer support plans receive access to core security checks and all service limit checks. Business and Enterprise support plans unlock the full suite of checks across all categories, plus API access and CloudWatch integration for automated monitoring.
You can access Trusted Advisor through the AWS Management Console, where it displays a dashboard with color-coded indicators showing the status of each check - green for no issues, yellow for investigation recommended, and red for action required. This makes it easy to prioritize which recommendations to address first for maximum impact on your AWS environment.
AWS Trusted Advisor - Complete Guide
What is AWS Trusted Advisor?
AWS Trusted Advisor is an online resource that helps you reduce cost, increase performance, and improve security by optimizing your AWS environment. It acts as your customized cloud expert, providing real-time guidance to help you provision your resources following AWS best practices.
Why is AWS Trusted Advisor Important?
AWS Trusted Advisor is crucial because it: - Helps identify cost optimization opportunities - Improves system performance and reliability - Enhances security posture - Monitors service limits to prevent disruptions - Provides actionable recommendations based on AWS best practices
The Five Categories of Trusted Advisor Checks
1. Cost Optimization Identifies unused resources, idle instances, and opportunities to save money. Examples include underutilized EC2 instances and unassociated Elastic IP addresses.
2. Performance Recommends ways to improve speed and responsiveness. Checks for overutilized instances and CloudFront configuration issues.
3. Security Identifies security gaps and vulnerabilities. Checks include S3 bucket permissions, security group configurations, and IAM use.
4. Fault Tolerance Helps improve application resilience. Examines Auto Scaling, Multi-AZ deployments, and backup configurations.
5. Service Limits Monitors usage against service limits to prevent hitting quotas that could impact operations.
How AWS Trusted Advisor Works
Trusted Advisor inspects your AWS environment and compares it against AWS best practices. It then provides recommendations in three status levels: - Green (OK): No issues detected - Yellow (Warning): Investigation recommended - Red (Action Required): Critical issues need attention
Support Plan Differences
Basic and Developer Support Plans: Access to 7 core Trusted Advisor checks covering basic security and service limits.
Business, Enterprise On-Ramp, and Enterprise Support Plans: Full access to all Trusted Advisor checks, plus programmatic access via AWS Support API.
Exam Tips: Answering Questions on AWS Trusted Advisor
1. Remember the five categories: Cost Optimization, Performance, Security, Fault Tolerance, and Service Limits. Questions often ask which category a specific recommendation falls under.
2. Know the support plan limitations: Basic and Developer plans only get 7 core checks. Full Trusted Advisor requires Business support or higher.
3. Understand it is a recommendation service: Trusted Advisor provides guidance but does not automatically fix issues. Users must take action on recommendations.
4. Differentiate from similar services: AWS Config tracks configuration changes, AWS Inspector assesses security vulnerabilities in EC2, while Trusted Advisor provides broad best practice recommendations.
5. Cost optimization scenarios: When questions mention finding unused resources or reducing AWS bills, Trusted Advisor is often the correct answer.
6. Service limit monitoring: If a question asks about tracking how close you are to AWS service quotas, think Trusted Advisor.
7. Security check examples: Common security checks include MFA on root account, open security group ports, and public S3 buckets.
8. Key phrase recognition: Look for phrases like best practices, optimization recommendations, or improve your AWS environment as indicators pointing to Trusted Advisor.
9. Integration awareness: Trusted Advisor can integrate with CloudWatch for monitoring and EventBridge for automated responses to check status changes.
