THE VIDEO above deals with a subject long explored here, more so during the first lock-down (spring of 2020). Many companies, with their staff working 'offsite', seem to have moved off Microsoft/IIS, belatedly saving money and improving reliability/availability/uptime.
"It's getting rather difficult to name any high-profile sites that still (in 2021) run IIS."Let's face it: no solid CMS exists for or is being actively maintained/developed for Microsoft frameworks. When it comes to Web servers, Microsoft long ago lost the fight. Some estimates we saw earlier this week said GNU/Linux has 90% or more of this market. Much of the rest is probably BSD or some UNIX that needs replacing (because it's severely outdated).
When it comes to active sites (what actually matters), Microsoft's share is becoming rather miniscule and that number is probably a lot lower if one considers top sites (e.g. as measured in terms of reach/traffic). It's getting rather difficult to name any high-profile sites that still (in 2021) run IIS.
So, Microsoft's IIS share (active sites) has collapsed another 4 percent in just one month. One month. This is part of an ongoing trend which further sped up or accelerated during the pandemic. While Microsoft makes claims and allusions to "Clown Computing" (to pretend there is growth by reclassifying old stuff) the matter of fact is that there are many layoffs and issues. They're going nowhere fast.
From the latest survey of servers:
Microsoft observed the largest drop of 2.2 million domains, while nginx and Apache lost 903,000 and 303,000. This resulted in a small loss of market share for all three, the largest drop being seen by Microsoft which fell 0.8 percentage points to 6.3%.
