Is Windows Server 2019 Serving Linux Containers Ready for Production?

Well, Microsoft Azure is one huge, global system, the second-largest cloud on Planet Earth, with millions of servers, almost all of which run Windows Server 2019 as the host OS, with even more millions of VM's running on top, millions of which are Linux.

So, uh, yes, it's ready for production.

> Our company only want Windows OS for Prod (not linux)

This is a very strange decision. You pay a licensing cost to use Windows; the purpose of this is to be able to use Windows software and development tools. It's not going to be in any way better than using Linux directly if the goal is to host Linux containers.

I would heavily question this, if I was in an environment where my employment was safe to do so.

Otherwise - who gives a shit if it's "ready for production"? The decision has been made. Spend your employer's money and if they have made a bad choice (and they have), it's on them.

If your company only wants windows for production, why would Linux containers be approved? Is it a tentative to circumvent the rule?

I’m in this same spot right now doing government contracting with only Windows server approved. On top of that open source software is only allowed if it’s “supported”. Between Anaconda Commercial and Windows, the universe of tooling is crazy small. All kinds of thing I’m used to are in this “runs on windows but isn’t officially supported and not a great choice for production” purgatory. I’m running flask through CGI on IIS. RQ/Dramatiq/Celery -> SQL Server + sqlalchemy + APScheduler. Its...annoying. At least I have Pandas.

A place I worked at a few years ago tried running HyperV for some use cases where it had licensing benefits. ~5000 VMs out of about 50000, mostly on VMWare.

At the time, the MS tooling was garbage, and we had a lot of operational networking issues. I would pay close attention to the tooling and the ops team capabilities.

If you need to use windows in prod, use Windows. Trying to get past a policy constraint with a hack like that ultimately isn’t a good idea for a variety of reasons. It’s not saving you money if the business breaks.

Hyper v works to serve Linux vms. You should always test your particular use case before committing. They have trial licenses.
