Which solution will meet these requirements?
Change the current single tag group to include only the Environment=Production tag. Add another single tag group that includes only the Name=ApplicationA tag.
Change the current single tag group to include the Department=Marketing, Environment=production, and Name=ApplicationA tags.
Add another single tag group that includes only the Department=Marketing tag. Keep the Environment=Production and Name=ApplicationA tags with the current single tag group.
Change the current single tag group to include only the Environment=Production tag. Add another single tag group that includes only the Department=Marketing tag.
Explanations:
By using two separate tag groups, one forEnvironment=Productionand one forName=ApplicationA, only instances with both tags will be selected. This ensures only instances withName=ApplicationAin the production environment are included, excluding the new instance.
AddingDepartment=Marketingin the single tag group would exclude the correct instances (ApplicationA in production) from deployment and still allow unintended deployments if other tags matched.
Adding a separate tag group with onlyDepartment=Marketingwould make this tag an “OR” condition, potentially including more instances instead of narrowing the selection to onlyName=ApplicationA.
Having separate tag groups forEnvironment=ProductionandDepartment=Marketingwould include instances matching either group, causing more unintended instances to be included, not justApplicationA.
I systematize that the answer is:
Change the current single tag group to include only the Environment=Production tag. Add another single tag group that includes only the Name=ApplicationA tag.
