AWS Trusted Advisor
Users can follow AWS best practices using the advice made by AWS Trusted Advisor. Checks are used by Trusted Advisors to assess user accounts. These audits reveal opportunities for streamlining your AWS infrastructure, enhancing security and performance, cutting expenses, and keeping an eye on service quotas. Then, you can implement the suggestions to maximize the use of your resources and services.
What is AWS Trusted Advisor, and How Does It Work?
AWS Trusted Advisor is an AWS product that provides real-time support in provisioning your resources by AWS best practices. It optimizes your AWS infrastructure, improves security and performance, lowers overall costs, and monitors service restrictions. Always use the advice supplied by Trusted Advisor while developing apps or as part of continuing development. It aids in keeping your solutions appropriately supplied.
The Trusted Advisor assesses a company's cloud architecture and makes suggestions based on best practices. The fundamental recommendations may be divided into three categories :
- A green check indicates no problems discovered.
- An orange exclamation mark was proposed after further investigation.
- The red exclamation mark is advised.
If you want to transfer to the AWS cloud or launch a new cloud application, Trusted Advisor's tips can assist you in optimizing your cloud architecture. For example, suppose you want to launch a new RDS instance and receive a warning from AWS Trusted Advisor that two of the 15 RDS instances have been inactive for over 30 days. In that case, you may investigate and plan to use one of the idle instances rather than launching a new one.

AWS Trusted Advisor Best Practices at No Charge
All AWS users may now perform the following Trusted Advisor checks :
- Check for Service Restrictions :
This check examines your consumption of the most critical service limits for each AWS product. It notifies you when you use more than 80% of your allocated resources, like EC2 instances and EBS volumes.
- Specific Ports for Security Groups Check with No Restrictions :
This tool will detect and inform you of excessively permissive access to your EC2 instances, assisting you in avoiding dangerous actions such as hacking, denial-of-service attacks, and data loss.
- IAM Use Check :
This check informs you if you are utilizing account-level credentials to govern access to your AWS resources rather than following security best practices and creating users, groups, and roles.
- MFA on Root Account Check :
The use of multi-factor authentication (MFA) to strengthen security by requiring extra authentication data from a secondary device is recommended in this check.
How to Get Started with AWS Trusted Advisor?
Trusted Advisor is accessible via the AWS Management Console. To do so, use the Trusted Advisor console.
Examine the check findings for your AWS account and then take the advised steps to resolve any concerns. For example, a Trusted Advisor may advise you to eliminate underutilized resources to lower your monthly costs, such as a bill for anything like an Amazon Elastic Compute Cloud (Amazon EC2) instance.
You may also utilize the AWS Support API to manipulate your Trusted Advisor checks.
Log In to the Trusted Advisor Interface

Benefits of AWS Trusted Advisor
The Trusted Advisor Benefits Checks examine your AWS infrastructure and offer recommendations for best practice-compliant activities.
Cost reduction :
By examining usage, setting, and spending, Trusted Advisor can provide you with cost-saving advice that you can implement. Examples include finding new EBS volumes, unconnected Elastic IP addresses, idle RDS DB instances, and Lambda function timeouts that are too high.
A trusted Advisor may provide actionable advice to help your services run better by examining the use and setup. Examples include computing utilization of EC2 instances, setups on CloudFront, and EBS throughput and latency analysis.
By recommending fundamental security best practices that security professionals have carefully selected, Trusted Advisor may help your AWS environment become more secure. Examples include determining the danger of access to RDS security groups, open access keys, and unused S3 bucket permissions.
Error sensitivity :
Your services' dependability might be increased with the aid of a trusted advisor. Examining Auto scaling EC2 groups, deleting Route 53 health checks, turning off Availability Zones, and turning off RDS backups are a few examples.
Maintenance regulations :
A service quota is the maximum amount of resources you may add to an AWS account. Quotas are implemented by AWS to safeguard you from unintended spending and to offer highly accessible and dependable service to all users. Trusted Advisor will let you know as soon as you fulfill more than 80% of a service obligation. Then, you can act upon suggestions to eliminate resources or ask for a quota increase.
AWS Trusted Advisor Explorer vs. AWS Systems Manager Explorer
AWS Systems Manager Explorer includes a multi-account overview of Trusted Advisor checks. There are some distinctions between the services :
- All AWS Trusted Advisor assessments, including performance, security, and reliability checks, will be aggregated by Systems Manager Explorer. Only recommendations for cost optimization submitted after examination will be aggregated by AWS Trusted Advisor Explorer.
- Systems Manager Explorer is available in all regions. However, AWS Advisor Explorer is only open in a few (AWS recommends the US-East region) since it relies on many services that are not available in all regions.
- AWS Trusted Advisor Explorer could provide additional flexibility because it is a CloudFormation template that users can edit. It also enables us to leverage AWS Athena data searches (SQL style), custom dashboards, resource tags, and external visualization tools. AWS Systems Manager Explorer allows queries using the AWS API to generate custom reports, and configurable dashboards with pre-defined widgets are available.
AWS Trusted Advisor Pricing
There are no long-term commitments and monthly billing for any premium AWS Support options. For Business and Developer Support plans, AWS Support costs are computed per account. You are charged for Enterprise On-Ramp and Enterprise Support depending on the total monthly AWS charges for all your account IDs that have those services subscribed.
The Developer, Business, Enterprise On-Ramp, and Enterprise Support plans monthly prices are computed using the previous month's total gross AWS charges (before any discounts or credits are applied).
As previously mentioned, a percentage of your monthly AWS costs, or the set minimum monthly rate, whichever is more extensive, will be charged as AWS Support fees. Users will be paying the larger of the monthly minimum or a percentage of their AWS costs for the time they are enrolled, even if they terminate their AWS Support subscription within 30 days of signing up. Any client who regularly signs up for and then discontinues AWS Support may be denied AWS Support at AWS's discretion.
When you prepay for Amazon EC2, Amazon RDS, Amazon Redshift, Amazon ElastiCache, Amazon Elasticsearch, and Amazon DynamoDB Savings Plans, Reserved Instances, and Nodes and are enrolled in a paid AWS Support plan, the upfront charges for each reserved resource are included in the calculation of your AWS Support fees in the month you purchase the resources. Furthermore, any recurring charges for these resources are factored into the calculation of your AWS Support fees for the month in which they occur.
Suppose you already have resources reserved when you sign up for a paid AWS Support plan. In that case, the upfront costs for those resources, prorated throughout the reservation, are considered for calculating the cost of AWS Support for the first month. As an illustration, if you buy a three-year Amazon EC2 All or Partial Upfront Reserved Instance on January 1 and enroll in the Business Support plan on October 1 of the same year, 75% of the upfront charge you paid in January is taken into account for determining your Support expenses for October.
