Pros

"IIS works natively with Windows Server without any issues in publishing certificates."

"The product is scalable."

"It has an intuitive user interface and provides a lot of options for building reports."

More IIS pros

"The products offers EE support."

Cons

"The documentation of IIS could be better. They are not easily accessible. I had to use YouTube and other online resources to learn how to use the solution properly."

"IIS could improve by Microsoft Windows improving the update services. We would like to be able to update all systems that are connected. The WSA service has to be in good order to accomplish this."

"I am using an older version of Windows Server IIS and the general management and navigation to get something done is not as straightforward as I hope it to be. The interface could be improved."

"This solution needs to be easier for cases where you want to have an IIS cluster."

"It lacks a few performance improvement tools."

"The graphical user interface has room for improvement and can be more user-friendly."

"The scalability depends on how you have set it up. If you're running IIS on a single server, it might not be as capable as if you are on many in a cluster or with load balancing and so on."

"The solution's stability needs improvement."

More IIS cons

"I would like to see integration with MQ systems."

Pricing and Cost Advice

"I didn't need to get an additional license for the solution since it was included in my server."

"IIS comes along with an OS license from Microsoft. Others can opt for a perpetual-based licensing model to be able to use the system."

"I give the price of the solution a five out of ten."

"The price of Windows Server IIS is expensive. They have a large user base, and they charge a little bit too much."

"The tool's pricing is on a yearly basis."

"The solution provides multiple licensing options."

"I was using the trial version of IIS inside my virtual machines."

"They offer a one-time payment model for the product license, and we pay annually for support."
