Description

Course Description:

Trying to ensure that your AWS infrastructure remains optimized at all times can be a daunting task.  By the very nature of AWS, your infrastructure is likely to be very fluid with the different resources used across your entire AWS account.  As this infrastructure grows within your organization, the management of it can get harder and harder.  How can you ensure that you are deploying your resources in the best way to ensure your costs are kept low, you're not over or under-provisioning instances, that your security is tight and that you are implementing the correct level of resiliency should a failure occur? The simple answer would be to use AWS Trusted Advisor.

The main function of AWS Trusted Advisor is to recommend improvements across your AWS account to help optimise and hone your environment based on AWS best practices. These recommendations cover four distinct categories:
Cost optimization - which helps to identify ways in which you could optimise your resources
Performance - this scans your resources to highlight any potential performance issues across multiple services
Security - this category analyses your environment for any potential security weaknesses or vulnerabilities
Fault Tolerance - which suggests best practices to maintain service operations by increasing resiliency, should a fault or incident occur across your resources

This course dives into the service to explain how it works and how you can use it to benefit your AWS account 

Learning Objectives

  • Understand the purpose and benefits of AWS Trusted Advisor
  • Learn how to navigate the AWS Trusted Advisor Console
  • Understand how to use AWS Trusted Advisor to optimize your AWS resources and account
  • Understand how to take actionable steps with AWS Trusted Advisor to improve your AWS infrastructure
  • Learn how to configure different methods of granting access to AWS Trusted Advisor using IAM policies
  • Understand how Amazon CloudWatch can monitor and react to changes within AWS Trusted Advisor

Intended Audience

This course would be of benefit to:

  • Security Professionals & Security Auditors
  • Systems Engineers and Administrators
  • CIO, CTO, IT Managers & Technical Business Leads
  • Compliance Managers
  • Anyone looking to learn more about AWS Security

Prerequisites

I recommend that you have a basic understanding and awareness of AWS and common services. It would also be advantageous if you have an understanding of IAM Policies, although this is not essential

This course includes

  • 6 lectures
  • 3 demonstrations

Transcript

Hello, and welcome to this short lecture, where I want to summarize some of the key elements of what we have covered for this course.

I started off by explaining what the service is and does, and here I explain that it can be found within the Management Tools category in the Management Console. The main function of Trusted Advisor is to recommend improvements across your AWS account, to help optimize your environment based on AWS best practices. Trusted Advisor focuses on four categories, with a list of best practice checks in each. Cost optimization, performance, security, and fault tolerance. There are currently 50 plus different checks between the different categories.

Your list of checks are very dependent on your AWS support plan. And Business and Enterprise support can take full advantage of all the checks available. All other AWS accounts only have access to six free core checks. These being, service limits, Security Groups Specific Ports Unrestricted, Amazaon EBS Public Snapshots, Amazon RDS Public Snapshots, IAM Use, and MFA on root account.

There are a number of useful features within Trusted Advisor these being Trusted Advisor Notifications. This tracks your resource check changes and cost saving estimates over the course of a week, and e-mails you a report. Exclude Items: This allows you to select specific resources to be excluded from appearing in the console within a specific check. Action Links: Action Links lead you on to remediate any issues identified. Access Management: Using IAM you can grant different levels of access to Trusted Advisor. And Refresh: You can perform a manual refresh five minutes after the previous refresh against either individual checks or against all checks.

Following this I focused on reviewing checks and taking the appropriate action. This lecture included a demonstration where I provided an overview of the Dashboard and performed the following steps: I looked at the Dashboard itself. I drilled down into the Trusted Advisor Checks. I identified and rectified the issues that were displayed. I refreshed the Trusted Advisor Checks to ensure the issues had been resolved. And I downloaded the status of the checks as an Excel file for offline review. Also provided an overview of the six core checks.

Following this lecture I focused on how to control access to Trusted Advisor, by demonstrating how to create a number of different IAM policies that could be used to grant access based on the following level of privileges: Full Access, Read Only access, access to specific categories, access to specific checks, and access to specific actions within Trusted Advisor.

Finally I covered how you can use Amazon CloudWatch to monitor and react to changes within AWS Trusted Advisor. Using CloudWatch Events, I performed a demonstration that showed you how to create a new rule within events of CloudWatch, with an associated SNS target.

That has now brought me to the end of this lecture, and to the end of this course. You should now have a greater understanding of what AWS Trusted Advisor is and does, and how you can use it within your environment to optimize your infrastructure. It is a powerful tool, especially if you do have a business or enterprise support plan, to fully maximize its potential.

If you have any feedback on this course, positive or negative please do leave a comment on the Course Landing Page. We do look at the comments and your feedback is greatly appreciated.

Thank you for your time, and good luck with your continued learning of Cloud computing.

Thank you.
