Is it possible to request that only data is stored in local cloud (may be IBM cloud) and all the products as such should be installed in Adobe's cloud (Like Amazon cloud)?
Appreciate your support.
No, you can not change where Adobe keeps it's data used within the solutions as a general rule. Some of the on premise solutions may have additional options for data storage (AEM & Campaign).
All of our SaaS solutions are built with heavy reliance on our back end infrastructure and data centers. As is the nature of a SaaS solution.
