AWS Tags and Resource Groups Training Summary

Tags in AWS

• Definition: Tags are key-value pairs attached to AWS resources.
• Usage: Commonly used for resource grouping, automation, security, and cost allocation.
• Naming Convention: Free-form, but common tags include Environment, Team, etc.
• Best Practice: It's better to have too many tags than too few.

Resource Groups

• Purpose: Allows grouping of AWS resources that share the same tags.
• Use Cases: Grouping applications, differentiating environments (e.g., prod vs. dev), and organizing resources by team.
• Scope: Regional service.
• Supported Services: EC2, S3, DynamoDB, Lambda, and more.

Tagging EC2 Instances Example

1. Instance 1:
   • Name: MyDevInstance
   • Environment: dev
   • Team: finance
2. Instance 2:
   • Name: MyProdInstance
   • Environment: prod
   • Team: finance
3. Instance 3:
   • Name: MyOtherDevInstance
   • Environment: dev
   • Team: operations

Creating Resource Groups

• Process:
  1. Navigate to Resource Groups.
  2. Create a tag-based resource group.
