"One of the most valuable features of Tomcat is its compatibility with the Apache web server and its ease of configuration.

Overall, Tomcat is a user-friendly application server that makes it easy to manage various aspects of database interactions.""The solution is scalable.""Tomcat is a simple, light environment, whereas the full Red Hat Fuse solution is heavier.""I would rate the pricing a ten out of ten, where one is high price and ten is low price. The pricing is pretty low.""Our company doesn't face any stability issues while using Tomcat.""It is a scalable platform.""The most valuable feature is how simple it is to deploy the solution.""It is easy to set up."

"In the next release, the tool should be more easily integrated and configured with other provisions. The pricing should also be made cheaper since it's very expensive now.""Occasionally, we encounter performance issues with IIS where it becomes unresponsive and requires a solution restart.""There is an issue with the network. The tool's price is also high.""The solution's scalability needs improvement.""At the moment, we have big problems with stability, and I'm not very happy at the moment. So, the stability could be improved.""The solution is slow and could have better performance.""IIS could improve by having some features related to ASR and HTTPS certificate generation.""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."

"Tomcat is not user-friendly. I would also like to be able to have multiple applications run at the same time.""The product's pricing needs improvement.""Vulnerability is one of the areas that can be considered an issue in the solution.""Tomcat needs to improve its stability.""If Apache can come up with a better solution to provide better security, that would be ideal.""Sometimes we face issues with the private and public networks and ensuring that once Tomcat is installed, that it is secure.""The solution cannot host .NET applications.""Security integration in Tomcat is complicated. We need to use another tool to solve the security issues."

  • "I was using the trial version of IIS inside my virtual machines."
  • "I give the price of the solution a five out of ten."
