Each of these capabilities use differing underlying technologies which are customized and purpose built to support ArcGIS Enterprise use case requirements.
None of these datastores are intended to be directly accessed by users. Instead, they are accessed by ArcGIS Enterprise and exposed indirectly to users via web services.
Direct access to the underlying technologies that support ArcGIS Data Store is unsupported.
Communication flows between ArcGIS Data Store and other component flows of ArcGIS Enterprise and the TCP ports used for these flows are described in the following documentation:
In a properly architected deployment, firewalls or other technologies like IPsec are used to limit access to these ports beyond the requirements specified.
