Senior System Integrations Architect at bs-team
Integrated web hosting has simplified secure services and has supported long-term growth
To be honest, I do not see any major areas for improvement. Perhaps something simple and minor. It should not go more complex than it is at the moment. The only disadvantage I see is that the documentation is a bit difficult to find. There is a lot of configuration that is very hard to get information about.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The product's initial setup phase is straightforward."
"The solution is easy to use, easy to maintain and isn't too technical."
"The product is scalable."
"The solution is very simple to use and easy to deploy."
"I think that the IIS includes most features that are required by web applications so that they can run smoothly on Windows operating system."
"It has an intuitive user interface and provides a lot of options for building reports."
"The initial setup of IIS is easy. The process takes only five minutes."
"The tool is very easy to use and efficient."
"The products offers EE support."
 

Cons

"The solution's scalability needs improvement."
"It would be beneficial if you could automate security certificate monitoring with IIS."
"The price of the solution could be less to improve."
"IIS has some stability issues and needs restarting."
"If Microsoft IIS could work well with AppOptics or things like PHP, Python, and other custom languages that run on the webserver, it would be ideal. I think there are cases where people need to use Apache instead of IIS when IIS doesn't work well with other web languages."
"IIS needs immediate improvements, especially in the area of security management."
"We'd like future versions to be more stable."
"Having no support for other than a Microsoft environment and programming languages limits the usage of IIS in many cases."
"I would like to see integration with MQ systems."
 

Pricing and Cost Advice

"This solution comes included with Windows Server."
"The price is good."
"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 solution provides multiple licensing options."
"There is no license needed to use the solution."
"The tool is included with Windows."
"There is an annual license to use this solution and the price could be better."
