Technical Lead at Cellulant Kenya

Offers high availability, straightforward deployment and easy to use

Tomcat could be a little bit more innovative. Tomcat could come up with a framework that's more lightweight and purely targeted at Java applications. Some other solutions are doing better right now, maybe because they have come up with MicroProfile, which I think is moving forward. It may actually beat Tomcat because of the lightweight nature of the framework, the MicroProfile. They're coming up with new solutions. So, for the future of Tomcat and to maintain the market share they might be looking for, they need to come up with initiatives to ensure that several of us have a lightweight framework to deploy applications on.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"The products offers EE support."

"It is easy to manage at a basic level."

"It is easy to set up."

"Tomcat is secure, reliable, and stable."

"Tomcat is a single-server solution for deploying applications that can scale effectively. It's a good choice because it simplifies deployment. Once you package your application, deployment is straightforward and efficient."

"Tomcat's best feature is the open source server. It's a flexible and lightweight solution."

"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."

"The scalability overall is good."

"The solution is convenient. It is a comfortable and easy-to-use solution for my use cases."

Cons

"I would like to see integration with MQ systems."

"Performance optimization is an area of concern in Tomcat that should be made better."

"Sometimes we face issues with the private and public networks and ensuring that once Tomcat is installed, that it is secure."

"The stability must be improved."

"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."

"Perhaps there could be an easier way to configure some advanced features."

"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."

"If Apache can come up with a better solution to provide better security, that would be ideal."
