How to deploy

Hi,
I am a newbie and with so much information it gets difficult to find out the practical details.
I have a small company (we are 3) and I want to automate our processes (we don't even have a file server). If I create a bundle of processes, how do I deploy it:
1 - Do I have to use on the Bonita platform, or can it be used somewhere else?
2 - If I need to use Bonita platform, does the Community edition works, or do I need to go for a paid version?
3 - If I can use another cloud platform, what are the requirements that I must request from them?
4 - If I use another cloud platform, how do I install the processes I will create on that cloud platform?
Probably all these questions are already replied on the documentation, but I am already drowned on so many information.

Thank you,
Rui
