I have a client who would prefer to host their application on Linux. However, my coworkers and I have very little experience with Linux. This is a short project with a low budget, so making choices that save time and money are not just desired, they're a must. We are also heavy on continuous integration and automation, much of which we already have figured out in Windows and can reuse from previous projects. That said, having the development team learn Linux and rebuild our automation so we can develop on the same environment to which we intend to deploy is most likely not a viable option. (For a larger project, perhaps, but not this one.) The team is familiar enough with Python that writing the application in Python is a viable option (even though most of our development is done in .NET), although we would need to figure out a good packaging mechanism that can run on Windows and be pushed to a Linux box. I don't anticipate needing any libraries unavailable on Windows. Most likely, we will only need
sqlalchemy in terms of libraries with native components.
All this makes the notion of having developers create the application on Windows, deploying to a Linux testing environment, and then pushing to production after thorough testing seem like a fairly attractive option, but I'm skeptical about it. Linux and Windows are very different operating systems, and I'm concerned about gotchas that could creep up and make life very difficult. Are there any real concerns with doing this (beyond the typical file path differences and other common things easily solved by good coding practices)? I think that a lot of shared hosting providers host on Linux, and I can't imagine everyone using them has developed on Linux for the past umpteen years. Is this done more commonly than I'm aware?
