Hi KevW​ – Great question. First, our goal is to ensure that you don't need to worry about vMode or its components. PostgreSQL should be completely behind the scenes for the operation of vMode – We want this to feel like an appliance. We’ll handle all upgrades, etc. You'll simply back it up and any major backup vendor will be able to provide this functionality.

In terms of complexity, PostgreSQL does not have any prerequisites and requires only the username/password at installation time. Additionally, it can provide the scale and HA functionality needed for vMode which can all be managed directly within vMode in the future.
