We performed a comparison between IIS and Tomcat based on real PeerSpot user reviews.
Find out in this report how the two Application Server solutions compare in terms of features, pricing, service and support, easy of deployment, and ROI."The solution is highly reliable."
"It is an easy-to-use and secure program."
"The initial setup of IIS is easy. The process takes only five minutes."
"The initial setup is simple."
"The solution is easy to use, easy to maintain and isn't too technical."
"IIS is easy to configure in terms of websites and other solutions."
"IIS's most valuable feature is user-friendliness."
"The solution integrates well with most Microsoft products."
"We chose to use Tomcat because it's perfect compared to other containers that we have tested."
"The most valuable feature is how simple it is to deploy the solution."
"The solution is readily available and open-source."
"Web apps are very easy to deploy."
"I love Tomcat for its scalability, reliability, availability, and steadiness."
"The deployment process is very fast."
"Our company doesn't face any stability issues while using Tomcat."
"The most valuable feature of Tomcat is its ability to export libraries into different instances so that I can use it not only in one application but in multiple applications."
"Compared to Linux, the solution’s Windows patching is slower. I would like to improve it."
"The initial setup could be made easier."
"The customer service and support team can be improved."
"The solution's black box is not fast."
"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."
"The solution is slow and could have better performance."
"In the next release, I would like to see better integration between the cloud environment and the on-premises environment."
"Sometimes if you are using IIS in large-scale scenarios, meaning that if you are deploying an application within IIS service and you are expecting a large number of users to use this application, you can sometimes find some problems, meaning that the service can shut down by itself unexpectedly if you don't configure your IIS with the correct configuration that can handle this number of users."
"In the solution, we are using the terminal to enter command line codes for operations and management, this is difficult for me. It would be better if we had some administrator UI tools for this."
"Tomcat is used mainly for database connections. As of now, we configure that environment for any database configuration. But if any utility can integrate where we can pass the database connection as a string of details, then it should encrypt them and keep them inside. From that security perspective, Tomcat requires improvement. They should integrate this security feature."
"The interface is not user-friendly."
"The product's pricing needs improvement."
"The high availability is not as robust as the competition is such as WebLogic and Jboss."
"The solution cannot host .NET applications."
"Vulnerability is one of the areas that can be considered an issue in the solution."
"The solution's interface and backup features could be better."
