Looking for some advise from the knowledgeable folks here. I am looking for a hosting provider and while my requirements are not unique, I am finding it difficult to get a clear answer. So here are my reqs without further ado:

- I want to start as cheap as possible.

- I want to use sqlite3, python flask, nginix proxy etc., and want to be able to change any of these in future as my development matures.

- I want to be able to move my site to a different provider in future. A lot of providers have their own managed databases etc which would make me code to that API, making a move to a different provider a hassle.

- My website uses very little data but I would rather not pay for the b/w because of DDOS horror stories I hear where I could be liable for a large bill for no fault of my own.

So far I think my only option is cloudflair for DNS and Digital Ocean VPS for hosting. It would keep my costs at $4/mo to start with.

Any suggestions? Anything I am missing?
