Good point, but then with Mono (a cross platform, open source .NET development framework => https://mono-project.com/Main_Page )

Yes, I agree. Mono seems a very good option and sticking with .NET framework may be an advantage for OutSystems and the investment already made.

Apache <-> Mono (.NET) <-> PostgreSQL <-> Debian Linux

Best multi-purpose Web server

As a module (.NET) to Apache

Best RDBMS :-)

An OS really stable :-)

And an Open Source, Community edition of the AgilePlatform, like the Fedora version of RedHat.

Yet Another Open Source tip:

Use SharpDevelop as a real good replacement for VisualStudio.

See: https://www.icsharpcode.net/OpenSource/SD

(or: https://monodevelop.com/ for MonoDevelop)

It's not what I meant by a "Community Edition" but it is a very good start !
