Is TDM supported in any cloud platform?
Release : 4.x
Component : CA Test Data Manager
As long as all ports are open and in same network and communicate with TDM server and Database, it should be fine to have TDM in cloud.
Don't have specific documentation on Cloud installation of TDM but the generic documentation is available at https://techdocs.broadcom.com/content/broadcom/techdocs/us/en/ca-enterprise-software/continuous-testing/test-data-management/4-8-1/installing/install-test-data-manager.html.
ARD 3.0 installation documentation is available at https://techdocs.broadcom.com/content/broadcom/techdocs/us/en/ca-enterprise-software/continuous-testing/agile-requirements-designer/3-0/installing.html
Also, don't need a new license for TDM and ARD 3.0. If ARD versions is before 3.0 then a new license is required.
