Projects

Creating and Configuring an AWS Organization

How-to-Guide

The challenge was to create an additional account for testing purposes that would be separate from the root account. To address this challenge, I set up an Organizational Unit and created a new account.

In this How-to-Guide, I explain how to create an admin user to administer the account. Then, I enabled Service Control Policies to only allow specific services and denied the disabling of Cloud Train.

Lastly, we tested the settings to verify that they are working.

AWS Configure Users with Organizations

How-to-Guide

In this project, I was in charge of establishing best practices for configuring an admin account to replace the root user. When a user account is created, they do not have access to any resources.

I then created a group and added the admin user to that group account. Afterward, I associated the user’s group with an account and added a permission set outlining what group members can access.
