AWS Service Catalog now enables updating of tags on provisioned products and associated resources. With this feature you can now update tags on provisioned products to ensure that your current tagging taxonomy is applied to provisioned resources. Administrators can enable tag updating on provisioned products via a Resource Update constraint, and owners can then update their provisioned products and adjust tags. Tag-only updates will not affect running resources.
AWS Service Catalog allows organizations to create and manage catalogs of IT services that are approved for use on AWS. These IT services can include everything from virtual machine images, servers, software, and databases to complete multi-tier application architectures. AWS Service Catalog is used by enterprises, system integrators, and managed service providers to organize, govern, and provision cloud resources on AWS.
