It's interesting your servers don't even have hard drives and is all based on RAM. That must take a lot of RAM. Is this a fairly common practice?
It is cheap enough to get 32 GB of RAM. This is enough to run our apps or a database for now. It is not common because it is difficult to operate and most companies do not need the security.
For some reason I was assuming you were storing data in them for the long term, but now I see you encrypt it and use hard drives. This makes much more sense, thanks.
