The AWS (Amazon Web Services) Trusted Advisor provides recommendations for security and infrastructure optimization. These recommendations help you follow AWS best practices, so you can reduce costs, improve security, enhance performance, and optimize your infrastructure.
You can follow the AWS Trusted Advisor to optimize your resources and services. Every AWS user has access to the Trusted Advisor core checks and recommendations. There are recommendations for the following categories:
- Security
- Performance
- Service limits
- Cost optimization
- Fault tolerance
You can rely on the Trusted Advisor to improve your cloud environment in the above categories.
Using AWS Trusted Advisor for Security Optimization
S3 Bucket Permissions
The AWS Trusted Advisor searches for S3 buckets with open access permissions. These buckets often result in higher charges, as objects in them access at a higher frequency.
Also, buckets that permit upload/delete access can lead to various security vulnerabilities, as unauthorized users can add, modify, or remove objects.
The S3 bucket permissions check also examines associated bucket policies that may override existing permissions.
Security Groups
MFA on Root Account
IAM Use
RDS and EBS Public Snapshots
AWS Trusted Advisor helps you protect crucial business data by monitoring your RDS and EBS. It provides alerts upon detecting any public snapshot or RDS or EBS Data. A public snapshot is available to all users and accounts.
Trusted Advisor identifies the snapshot and alerts you in real-time so you can investigate it.

Using the AWS Trusted Advisor for Service Limits
The Trusted Advisor service limit check allows you to monitor resource usage and how close you are to reaching your service limits. It’s an essential part of managing deployments in AWS. Once you reach the service limit, you can request an increase or shut down the resources before you reach the limit.
Once a service limit is about to be reached, the AWS Trusted Advisor sends notifications via Slack or email, which enables you to request a quota increase or shut down immediately.
Using Trusted Advisor for Fault Tolerance
The AWS Trusted Advisor provides recommendations on run fault-tolerant systems that can remain in operation in the event of failures.
The Trusted Advisor recommends the distribution of EC2 Instances across different Availability Zones in a region. Since the failure in one Availability Zone doesn’t affect the other, you can protect a single point of failure by launching in multiple zones in the same region.
Other ways in which the Trusted Advisor ensure fault tolerance include:
- Amazon RDS Backups
- Amazon RDS Multi-Availability Zones
- S3 Bucket Versioning
- Auto Scaling Group Resources
- Load Balancer Optimization
Using AWS Trusted Advisor for Performance Optimization
The AWS Trusted Advisor allows you to optimize the performance of your cloud environment by checking your service quotas and providing recommendations where necessary. Optimization of services allows you to take detect any unused resources, monitor for overutilized instances, and utilize provisioned throughput.
The Bottom Line
While these are the core checks and recommendations, there are over 60 additional checks that you can perform. It’s best to determine how many Trusted Advisor checks are available for your cloud.
The AWS Trusted Advisor is a robust service that can help you run an optimized cloud environment. With this service, you can minimize cost, run fault-tolerant services, optimize performance in your AWS, and more.
