We have quite a few customers implementing VoltDB in a micro-services architecture. I would like to learn more about your application before I can determine if VoltDB is even a good fit for you are trying to do. Typically VoltDB is a separate independently scaling database layer while the microservice container itself is "glass to ESB interface" or a subset of that depending on your architecture. May I suggest we chat a little bit more about your specific application. You can join our public slack at http://chat.voltdb.com/
and DM me. My id in our public slack is dremella. Alternatively, you can email me at dremella (at) voltdb (dot) com.
