Trusted Advisor
LOW
AWS Trusted Advisor scans your AWS infrastructure and compares it to AWS best practices. It serves as a resource to help reduce cost, increase performance, and improve security by advising on various aspects of your AWS environment.
Learning Objectives
- Understand the core purpose and functionality of AWS Trusted Advisor.
- Identify the categories of AWS best practices that Trusted Advisor evaluates.
- Recognize specific issues, such as unattached or underutilized EBS volumes, that Trusted Advisor helps optimize.
- Differentiate Trusted Advisor's primary focus from areas like regulatory compliance and governance, and identify related AWS services for those aspects.
Categories of Checks
AWS Trusted Advisor focuses on a set of core categories to help optimize your AWS environment, identifying opportunities for improvement across different aspects of your infrastructure.
Trusted Advisor checks are grouped into categories to provide actionable insights based on AWS best practices.
Cost Optimization
Identifies resources that are unused or opportunities to lower your AWS bill.
Use Cases:
- Identifying unattached and underutilized EBS volumes
- Finding opportunities to lower AWS bill
Fault Tolerance
Highlights redundancy shortcomings, identifies overused resources, and flags potential service limits to improve the reliability of your solutions.
Use Cases:
- Improving reliability of solutions
- Addressing redundancy shortcomings
- Identifying overused resources
- Flagging potential service limits
Service Limits
Displays your current usage limits for AWS services and resources.
Use Cases:
- Monitoring current usage against AWS service limits
Security
Trusted Advisor's Security checks look for potential vulnerabilities, like S3 buckets with public access or security groups open to the internet.
Use Cases:
- Identifying S3 buckets with public access
- Flagging security groups open to the internet
Performance
Trusted Advisor checks five categories of best practice compliance, which includes performance, to help optimize your cloud environment.
Use Cases:
- Optimizing the cloud environment
Specific Optimizations and Checks
Trusted Advisor provides detailed checks for various resource types to offer actionable recommendations.
AWS Trusted Advisor provides a cost optimization check that specifically identifies unattached and underutilized EBS volumes within your AWS environment. These volumes, while not actively used, can still incur storage costs. By flagging these resources, Trusted Advisor helps you reduce unnecessary expenses by either deleting or repurposing them.
Scope and Limitations
Understanding what Trusted Advisor primarily focuses on, and what it does not, is crucial for effective cloud governance.
The categories that AWS Trusted Advisor does not primarily focus on, compared to the given options, is Policy Compliance. While AWS Trusted Advisor can indirectly help improve your security posture and adherence to some best practices that could align with certain policies, it's not designed to specifically check or enforce adherence to regulatory compliance policies like PCI DSS or HIPAA.
Other AWS services like AWS Config and AWS Security Hub are more focused on compliance and governance.
Exam Focus
- AWS Trusted Advisor's core categories explicitly highlighted as primary focus are Cost Optimization, Fault Tolerance, and Service Limits. Remember that Policy Compliance (for regulatory adherence) is NOT a primary focus for Trusted Advisor.
- AWS Trusted Advisor is the specific service used to analyze infrastructure for identifying unattached or underutilized EBS volumes for cost optimization.
Glossary
- Cost Optimization
- Identifies resources that are unused or opportunities to lower your AWS bill.
- Fault Tolerance
- Highlights redundancy shortcomings, identifies overused resources, and flags potential service limits to improve the reliability of your solutions.
- Service Limits
- Displays your current usage limits for AWS services and resources.
- Policy Compliance
- Checking or enforcing adherence to regulatory compliance policies like PCI DSS or HIPAA, which AWS Trusted Advisor does not primarily focus on.
Key Takeaways
- AWS Trusted Advisor is an essential service for continuously scanning your AWS environment to ensure adherence to best practices in areas such as cost optimization, fault tolerance, and service limits.
- It helps reduce unnecessary expenses by identifying underutilized resources, like unattached EBS volumes, and improves reliability by highlighting potential issues before they impact operations, though it does not primarily focus on regulatory compliance.
