IIS To NGINX

We have moved our hosted applications from the Microsoft Internet Information Services server (most commonly known as Microsoft IIS) to a NGINX server. Most of our applications are built with the Microsoft .NET Core framework and it's common to host them in IIS server. Both are products of Microsoft and they integrate well. We have hosted them in IIS server in a Windows VPS by a 3rd party VPS service provider on a bi-annual subscription. Our recent migration from a Windows server to a Ubuntu server and our in-house SaaS product (under active development) of a multi-tenant storefront required us to look for a versatile web server with powerful reverse proxy capability to handle subdomain and subpath URL routings and we found NGINX web server fulfil all our requirements. NGINX is open-source software for web serving, reverse proxying, caching, load balancing, media streaming, and more. It was fast and well-documented. We were able to quickly set up the web server and configure it to serve a support web application in a subdomain under a subpath of the same domain name used for the product's landing website.
