Efficiently Using a Remote Database

[Dan Banks]

I want to set up a remote database to be able to work on a personal project from two different computers.

First off, because Amazon offers so many options, do any of you recommend a particular free container?

Secondly, to minimize data movement between the remote database and my local machine, I am thinking of setting up some sort of system for end-of-session synchronization. One concern of mine is whether I will need to transfer each collection in its entirety, or does MongoDB support a synchronization mechanism to ensure only the difference between the two databases are transferred? Am I over thinking this?

Finally, I need to be able to synchronize both ways.
