Update to the Service Catalog based Reference Architecture
This step is optional, but recommended.
If you haven’t already, it is recommended to update your Reference Architecture to the Service Catalog based version. This is not strictly necessary to leverage the DRY configurations. However, the Service Catalog based version utilizes constructs that are more friendly to DRY across environments. By switching to the Service Catalog based version, you will see more common configuration across your environments, allowing you to DRY your configuration further.
An additional consideration is that the Service Catalog upgrade guide assumes the original Reference Architecture, and not the DRY version. If you update to the DRY version first, then the guide will no longer be compatible with your Reference Architecture, complicating a later migration to the Service Catalog. Updating to the Service Catalog from a DRY Reference Architecture version is not fully supported by Gruntwork.
