"One of the most valuable features of Tomcat is its compatibility with the Apache web server and its ease of configuration. It is simple to set up and maintain and allows for easy management of database connections, transactions, and isolation. Overall, Tomcat is a user-friendly application server that makes it easy to manage various aspects of database interactions.""It is a robust solution.""Tomcat is user-friendly and easy to set up, especially compared to WebLogic or JBoss where some specialty is required. If you are going for Tomcat, you can use their guidelines and can set it up easily.""Tomcat is a simple, light environment, whereas the full Red Hat Fuse solution is heavier.""We chose to use Tomcat because it's perfect compared to other containers that we have tested.""Our company doesn't face any stability issues while using Tomcat.""The solution integrates smoothly with the development environment. The integration process is straightforward. You only need to configure the project in your IDE. With intelligent features, the integration becomes even easier. Once integrated, deployment into our application is straightforward. Previously, we sometimes relied on manual deployment processes or used a separate application manager. However, with this solution, deployment is simplified.""It's very stable. No problems at all. I would rate the stability a ten out of ten."

Cons
"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 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.""The solution's stability needs improvement.""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 solution's scalability needs improvement.""Performance-wise, certain improvements in IIS are needed...IIS is not scalable. Its scalability is less.""IIS could improve the error logging. There are times we are not able to see the errors. More details would be helpful. Additionally, the configuring of the IIS should be allowed through coding instead of the classic view.""The platform's stability could be better."

More IIS Cons →

"Tomcat is a polished product that has been around for a long time. It should be simple and high-performing, with the ability to grow and maintain stability. The fewer features it has, the more stable it will be.""The setup is complex and could be improved.""If it could support the driver's VIN, they can run natively without the GBM. Now, we can run what we call the native cloud application that doesn't require GBM. If Tomcat can support that, it's going to improve performance and backup.""It will be useful if a direct report concerning a particular server configuration or application usage is readily available in the dashboard.""Sometimes, the UI part does not run properly, or the server goes down.""The solution's interface and backup features could be better.""Security integration in Tomcat is complicated. We need to use another tool to solve the security issues.""Vulnerability is one of the areas that can be considered an issue in the solution."
