"Web apps are very easy to deploy.""The most valuable feature of this solution is that it supports Java Enterprise."

More Tomcat Pros »

"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 areas of this solution that need improvement are monitoring, debugging, and troubleshooting.""The solution should improve the cluster environment and load balancing.""This solution needs to be easier for cases where you want to have an IIS cluster.""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.""We've never had any issues with the solution, but it's still nice to have overall improvements on it. It could be easier and faster to use, for example.""The documentation is not very detailed. They need to improve it and add to it. They should ensure there are lots of visuals to help users better understand the solution.""In the next release, I would like to see better integration between the cloud environment and the on-premises environment."
