Central console enables us to see all of the activated and deactivated computers but it has poor alerts and frustrating technical support

The solution needs to allow for other company product licenses to be included if possible. The solution needs to include other Microsoft products, like Exchange, SharePoint, etc. Right now, it's only for Windows and Office. The solution needs to be made web-based. Right now, we have to install some tools and to use these tools we have to log into a specific server. If that server has an issue we cannot manage it. The solution needs to be able to be managed from any machine. Alerting capabilities should be improved. If a license expires or there is a breach, or something is non-compliant, the solution should send out alerts.

"IIS is easy to configure in terms of websites and other solutions."

"The solution is easy to use and connects with Microsoft."

"The product is easy to configure."

More IIS pros

"The most valuable aspect of the solution is the central console, that allows you to see all of the activated and deactivated computers."

Cons

"Presently, some developers do not have technical knowledge of managing IIS, so that needs to be improved in the next release."

"Scalability issues and security concerns need attention from Microsoft."

"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."

"Performance-wise, certain improvements in IIS are needed...IIS is not scalable. Its scalability is less."

"It would be beneficial if you could automate security certificate monitoring with IIS."

"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."

More IIS cons

"The stability of the solution needs improvement."

Pricing and Cost Advice

"We purchased a Microsoft Windows license and the license for IIS came in the package."

"I think it's part of the Windows Server, so you won't have any other costs to add in order to use the IIS service."

"The tool is included with Windows."

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

"IIS's pricing is reasonable."

"The solution’s pricing is yearly. The pricing is affordable and not high."

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

"Users can get a subscription-based license or a perpetual license for IIS."

Overview

Internet Information Services (IIS) provides a secure, easy-to-manage, modular and extensible platform for reliably hosting websites, services and applications. With IIS, you get choice and control without giving up reliability or security.

Microsoft

Windows Process Activation Service generalizes the Internet Information Services (IIS) process model, removing the dependency on HTTP. All the features of IIS that were previously available only to HTTP applications are now available to applications hosting Windows Communication Foundation (WCF) services, by using non-HTTP protocols. IIS 7.0 also uses Windows Process Activation Service for message-based activation over HTTP.
