There's no reason the company selling them support couldn't be providing support for QEMU btw. If it met their needs otherwise I'm sure they'd consider it.
I don't know what business you're in and maybe after a nightly tape backup there's nothing important for you to lose. Frankly that's most small businesses. But if you've got real trade secrets get a proper IDS/IPS before you regret it.
Sure but the problem here is can you find and retain the people who can do that work, if you are a big lumbering "un-interesting" company where tech is not your core focus? In most cases the answer is "no".
There's a reason major software vendors provide professional services. If their customers could reliably hire and (most importantly) retain experts on their own, they wouldn't need professional services.
This. As a tech person with decades of professional services experience in the tech space, I couldn't agree more.
Generally, there are three reasons why corporate entities hire professional services (this isn't limited to tech stuff either):
1. There's a specific need for design/implementation expertise where FTEs are either not readily available or are unnecessary once the implementation is complete;
2. The internal group in favor of a particular technology/implementation wants/needs validation from "experts" to get full buy-in from management;
3. Professional services are brought in to "validate" existing project plans/implementation details as a CYA against project failure (e.g., "the consultants told us this was the way to go. They were wrong, not us.") which (both bringing in consultants and project failure) happens a lot more often than you might think.
I work for a large enterprise and we pay or retain vendors to do things for us all the time, at a much higher cost than it would be to do it in house, because we cannot find/hire/retain the expertise to do it ourselves, and at some point we need to get the work done so that other more mission-critical work can happen to drive the business forward.
Plus, there is value in paying someone to make the find/hire/retain part their problem instead of ours.
We buy the reliability of getting the work done in a timely manner, on top of the work itself.
Plenty of companies seem to be OK with using GPL2-licensed Linux, why wouldn’t qemu be the same?
