For my side projects I use Visual Studio express editions (free) and use postgres (local) for one and mongodb (hosted at mongolab) for another for storing data.

For my side projects I use Visual Studio express editions (free) and use postgres (local) for one and mongodb (hosted at mongolab) for another for storing data. I host both of them on 1 VPS with single core and 1 GB of RAM. So All I am paying extra is 2$ a month for a windows vps instead of a linux vps, and I think that 2$ extra that I am paying is well justified.
