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

"It is a stable solution compared to other vendors."

"It is a scalable platform."

"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."

"The deployment process is very fast."

"The most valuable feature of this solution is that it supports Java Enterprise."

"It is a robust solution."

"I find the quick startup valuable, particularly the static quick startup."

"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."

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

More Tomcat pros

Cons

"Its support documentation could have detailed information on database integration."

"Technical support is limited."

"Java functions should be built better into the solution."

"The solution's interface and backup features could be better."

"The solution cannot host .NET applications."

"I would personally like it if the admin console would show more information specifically about memory being used."

"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."

"I have no recommendations for improvements."

"One way to improve the solution is by making the logging capabilities of Tomcat better by providing a logger within the server itself and making it easy to access and view the server logs. This can be especially useful when debugging issues with applications deployed on the Tomcat server. By having the ability to view both the application logs and the server logs, you can more easily identify the source of any issues and troubleshoot them more efficiently. Providing a connector or other similar feature that allows you to access the server logs from within your application can also be helpful in this regard. Having access to both the application logs and the server logs can be a valuable resource when trying to identify and resolve problems."

Pricing and Cost Advice

"It is less costly than one of its competitors."

"Tomcat is open-source and free to use."

"If it is a community version of the solution, no payment is required. However, if it is a Linux version, we must buy the solution from JBoss."

"The solution is open source so is free."

"I give the pricing an eight out of ten."

"Tomcat's pricing is very cheap."

"It's open-source. We don't pay for the license."

"It is an expensive product."

"I rate the product's price an eight on a scale of one to ten, where one is a high price, and ten is a low price."
