AWS Patch Tag Naming Update
*Update on patch tag naming after new finding. No space or _ to be used.
Beginning July, AWS team converted patch tags naming from
· Patch Group to PatchGroup
· Patch Window to PatchWindow
The tag name change in AWS will "Allow tags in metadata" setting to be enabled on instances, to align with the system requirement and avoid metadata-related issues. The updated tag format will be used going forward.
The patching team completed all ITC changes according to the following schedule:
· Lower Environments: July 20-21, 2026 (Completed)
· Production: July 29, 2026 (Completed)
· Marketplace Production: August 9, 2026 (Completed)
As this is a behavioral change in the patching process, Technical Advisors are requested to coordinate with their respective ADOs and hosting coordinators to ensure the new tag format is updated and adopted in all future deployments. This change is specific to AWS patches only.
Please contact Enterprise Patching Team for questions / concerns.
