Frederic Hautecoeur - PeerSpot reviewer
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.

We use the solution for web services.
It would be good to enhance the schedule interface. There is no indication that lets us know if a module has stopped. Shortly speaking, each business host has color in the Production page. Meanings of colors are described in a "Legend" link on the Production page. Also, each business host either has or has no private pool (processes that work with its queues). When we stop a business host by scheduling, its private processes are killed (if they exist). Such a situation is not expressed in changing business host color. The only way to check if a business host is stopped by scheduling is to check its processes presence.

Quotes from Members

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

Pros

"The tool shows us the operating systems where our servers and applications are running."
"The most valuable feature of the solution is that it is easy to use and easy to understand."
"IIS's most valuable feature is user-friendliness."
"I think that the IIS includes most features that are required by web applications so that they can run smoothly on Windows operating system."
"All the features of Microsoft IIS are valuable."
"What I like the most is that it is easy to use."
"The solution has been reliable."
"It is an easy-to-use and secure program."
"The InterSystems technical support (WRC) is perfect and highly qualified."
 

Cons

"Microsoft products can only work within the Windows environment, which limits their versatility."
"The solution must improve the integration between its databases."
"Finding different settings can be difficult if you don't know where to look."
"It should be more user-friendly because unless you know how IIS works as a Microsoft product, a system admin cannot just manage it."
"I see that IIS has maintained the same interface for a long time, so they could potentially use more automation or integrate Copilot into it to make it easier to use."
"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."
"The only issue I've encountered is with certificates not working fine sometimes. It's influenced by the server's service performance."
"There is an issue with the network. The tool's price is also high."
"It would be good to enhance the schedule interface."
 

Pricing and Cost Advice

"The price of Windows Server IIS is expensive. They have a large user base, and they charge a little bit too much."
"We pay a yearly licensing fee for the solution."
"There is an annual license to use this solution and the price could be better."
"I give the price of the solution a five out of ten."
"There is no license needed to use the solution."
"The licensing cost is dependent on the usage."
"Users can get a subscription-based license or a perpetual license for IIS."
"IIS's pricing is not expensive."
