Microsoft IIS vs Unicorn: What are the differences?
Developers describe Microsoft IIS as "A web server for Microsoft Windows". Internet Information Services (IIS) for Windows Server is a flexible, secure and manageable Web server for hosting anything on the Web. From media streaming to web applications, IIS's scalable and open architecture is ready to handle the most demanding tasks. On the other hand, Unicorn is detailed as "Rack HTTP server for fast clients and Unix". Unicorn is an HTTP server for Rack applications designed to only serve fast clients on low-latency, high-bandwidth connections and take advantage of features in Unix/Unix-like kernels. Slow clients should only be served by placing a reverse proxy capable of fully buffering both the the request and response in between Unicorn and slow clients.
Microsoft IIS and Unicorn belong to "Web Servers" category of the tech stack.

This is a legacy system requirement. We have some portions of our website written in PHP. Normally this wouldn't be an issue but at the time they decided to use PHP+Windows they were also trying to use MSSQL databases (All the microsoft influence was due to some azure credits the company received early on). The particular driver they ended up picking forced them into using the
mssql_* functions instead of PDO. This meant that the majority of the site used these rather outdated calls and replacing them was a rather large endeavour. So while we migrate some of the PHP backend away to various node.js api systems we are simply sustaining the existing PHP portions.
Rolling deploys are awesome! We use Unicorn to keep downtime to a minimum as we iterate quickly for our clients.
