Tags in AWS are essential for organizing resources based on their purpose, owner, or environment, and can also aid in cost tracking when unique key-value pairs are assigned.

How to Tag Resources on AWS

  1. Using AWS Console:

Navigate to the desired resource, such as an EC2 instance, and follow these steps:

  • Select the instance from the list view.
  • Go to the Tags tab and click on the Manage tags button.
  • Add a new tag with a unique Key and Value.

  • Save the changes.
  1. Using AWS CLI:

Use the following command-line example to create a tag for an EC2 instance:

aws ec2 create-tags \
  --resources i-1234567890abcdef0 \
  --tags Key=webserver,Value=dev

For each project, tag all its resources with:

Project=project_name (e.g., ciroh-hydroshare, ciroh-fim) Double-check the tag name with the AWS main account admin to make sure it fits well with our naming scheme.
