We have helped clients in several industries and sectors where these words either mean different things, or people who use them are thinking of different things. An appliance has meant a physical thing before it has also meant a VM, and I have worked on projects where we used both.
The question you have asked includes solutions, which introduces a bias. Many client meetings start with that. This is what's called an XY problem[0], where the client says they want want Y, but that's their implementation of a solution to solve X. That may or may not be the only solution, but finding out the actual problem to be solved has never hurt me and saved a lot of time and money.
This is why we spend time defining the problem and stripping away every word of jargon we can, because that jargon can create a bias towards a solution that may not be optimal. For example, site-to-site VPN. Why? Gateway ? Why ? These are solutions. What's the job to be done.
Anyway... Have a look at https://www.replicated.com/ and https://kots.io/
