It all makes me feel very stupid. I did programming since childhood and web since the beginning, I was clouds (virtualization) user even before millennium, I do backends for a living, saw a lot of JS code, know something about mobile apps, but I must join this thread.

"Parse Server is an open source version of the Parse backend that can be deployed to any infrastructure that can run Node.js" - each of these words one-by-one do have some meanings, but altogether they have none, neither your explanation for me. I fully believe it's totally my fault and it's hopeless, so please no reply.
