Why did SSRS move away from IIS?

Question

My situation which doesn't have a solution since Microsoft removed IIS and went with internal Http.sys:

I need to enable security via SSL/TLS on my SSRS server. I have 20 web apps that reference SSRS front end using HTTP, since SSRS doesn't use IIS I can't use URL ReWrite module for IIS 10.x. SSRS has no provision for HTTP to HTTPS rewrite.

Since I inherited these 20 web apps, I will have to find and modify all code references that use HTTP and convert them to HTTPS (find and replace will not work in all cases based on how this very old code is written). Next I'll have to schedule downtime for TLS/SSL cert install and setup. Then I'll need to deploy my 20 web apps with updated HTTPS references.

NONE of this would be needed IF Microsoft continued with using IIS for SSRS. So why on earth did Microsoft end that functionality?

Hi @Rob Ainscough,

You can install and run SQL Server Reporting Services (SSRS) and Internet Information Services (IIS) on the same computer. The version of IIS that you're using determines the interoperability issues you must address.

Details you may check Install Reporting and Internet Information Services side-by-side
