Way, <i>WAY</i> too many corporate IT divisions.
Some banks still use IIS.<p>Every large company big enough to host an intranet is running IIS somewhere, possibly everywhere. It integrates well with AD so some really complex tasks become stupid simple.<p>It's seeing less and less usage as the world moves to AWS which is equally stupid because you're tied to one vendor's proprietary products (Amazon) again. Except this time you don't own the hardware.<p>Public sector IT <i>loves</i> IIS. Check your municipality's tax or property website it's probably got .aspx scripts out the ass.<p>I've seen it hosting European web apps, public sector if I recall. Lots of bespoke .NET applications out there with SQL Server backends running entire local governments.<p>Asian countries especially China and Taiwan love IIS and use it to host anything and everything. This is a personal observation.<p>Sure the world has mostly moved on, but there's tons of legacy code out there that keeps cities and <i>really important organizations</i> humming that runs on IIS and it's never changing.<p>You think that's bad, there's still places out there running AS/400 stuff on the web, Lotus Notes, and Novell Groupwise (gasp).
Yeah, I regularly speak to folks still running IIS on Windows Server. There are a lot of old apps out there, sadly. Some really, really important ones.
Lots and lots<p>A lot of Microsoft devs know very little Linux historically as they used windows and are comfortable with it<p>Decreasing due to cloud and Nodejs takeup
IIS also sits at the back of a many "modern" cloud web type services.
Amazingly some companies like Hyland still ship software that requires IIS. Bonus add are the pages and pages of setup instructions.
A lot of big corps still use it.<p><a href="https://bloomberry.com/data/windows-server/" rel="nofollow">https://bloomberry.com/data/windows-server/</a>
SharePoint uses it extensively
The entire solarwinds platform(barf)
I would say 75% of my webservers are IIS.<p>Nothing internet facing mind.
Yes, but typically just internal corporate intraweb stuff from what I've seen.
Tons of the Navy's public websites still run on it.
The text uses target.com as a placeholder but they actually also have an IIS blue screen: <a href="https://knslsd.target.com/" rel="nofollow">https://knslsd.target.com/</a>
Back in the early-2000s, I passed the Microsoft certification exam for IIS. I had never even heard of the product (I was told my company had some extra credits at the testing center, I was there taking another exam (Solaris 8 certification), so I figured <i>why not?</i>) I know, MCSE exams were notoriously simple back then, but good god - usually, for every question, 3 of the 4 possible answers didn't even make sense. Anyway, I figured there was no way IIS would last if any dipshit could become "certified" in the product.
That's the value add. Any dipshit can be trained in the Windows server stack, so you can staff your back office with dipshits. For a while in the early 2000s—before the cloud era—Windows was routinely found to have a lower TCO than Linux as a server OS for precisely this reason. More actual deployments too, especially in corporate intranets.
