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."

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

"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."

"Tomcat's ease of use has positively impacted project timelines. Tomcat already has high availability – it doesn't go down so often and doesn't require a lot of maintenance. As long as your application works, you can depend on Tomcat."

"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."

"The most valuable features of this solution are the general web server features."

"The solution is scalable."

"I like the solution’s ease of use."

"We use Tomcat for various purposes, and our company finds it to be perfect; we are getting all the solutions out of that."

Cons

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

"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."

"Tomcat needs to improve its user interface."

"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."

"Tomcat's performance is less than other solutions like IBM WebSphere or JBoss."

"I would also like to see a dashboard with some integrations in order to see the logs and trace performance easier."

"Technical support is limited."

"I have no recommendations for improvements."

"Security integration in Tomcat is complicated. We need to use another tool to solve the security issues."
