What is Tagging?

Tagging is a way to assign a label to an AWS resource. Tags enable you to categorize your AWS resources in different ways. For example, you can categorize by purpose, owner, department,or environment. Each tag consists of a key and an optional value (for example, Department: Finance), both of which you define.

Why is tagging important for MAP?

For the purposes of MAP, tagging of migrated workloads with the specific map-migrated tag (tag key is case sensitive) is necessary to enable the following:

  • Tracking of the migration inventory scope, as it is migrated over time from your existing environment to AWS
  • Identification of the specific AWS resources being used in place of existing pre-migration resources
  • Collecting the cost and usage data of all the migrated resources, which can be used by you to report TCO and other financial data

The tagging exercise is done when the workload is migrated to AWS. Typically, tags are applied by the workload owners who will be migrating their workloads. This process is repeated as workloads are moved across until the entire MAP migration scope has been migrated.

Tagging your AWS resources is a best practice even outside of MAP. For more information, see the Tagging Best Practices Whitepaper.
