Executive SummaryUpdated on Mar 8, 2026

Tomcat and IBM Open Liberty are competing server platforms for deploying Java applications. IBM Open Liberty seems to have the upper hand due to its advanced features and support structure.

Features: Tomcat provides a lightweight architecture, serving basic deployments with support for Servlet and JSP specifications, and easy integration with existing systems. IBM Open Liberty offers MicroProfile and Java EE support, a modular architecture, and enhanced capabilities for cloud and microservices, making it suitable for complex enterprise environments.

Ease of Deployment and Customer Service: Tomcat offers straightforward deployment but relies on community forums for support, which may not meet enterprise-level needs. IBM Open Liberty offers smoother deployment through tool integration for complex setups and professional support, making it reliable for enterprises requiring robust assistance.

Has enabled flexible deployment of modular services with high availability and smooth dynamic updates

The best features of IBM Open Liberty are the implementation of MicroProfile and Jakarta EE, along with fault tolerance and high availability. It's easy to use and deploy new features. The profile is easy to configure and set up features. For example, using fault tolerance from MicroProfile or using servlets or JAX-RS allows for easy configuration and creation of modular applications. The configuration is modular. The main point for us in this project was high availability, high performance, and the implementation of MicroProfile and Jakarta EE. We utilized the modular architecture of IBM Open Liberty by creating different microservices using different environments. We created different configurations for different services using the configuration of IBM Open Liberty. This was very beneficial. We created different environments only by changing the configuration, depending on the functionality we needed. It was good and very flexible for us. I used the dynamic updates feature of IBM Open Liberty and different configurations in different services and servers, based on the functionality we provided for our clients. The flexibility to create different services in different environments using IBM Open Liberty was important. The high availability is guaranteed by the architecture of IBM Open Liberty, Java, and MicroProfile. The architecture guaranteed high availability, and the flexibility comes from being able to configure needed features. There's no need to load all WebSphere or functionalities in all environments. I can configure it and create a more highly available and scalable process. I implemented monitoring tools for IBM Open Liberty using Grafana and OpenTracing using the functionalities from MicroProfile and IBM Open Liberty. The monitoring tools helped with managing system performance.

Customization and flexibility enhance web applications while support effectively resolves queries

Regarding improvements in Tomcat, I personally haven't used it very extensively, but all Apache products are very useful for our web applications. Although the web server setup is a little different, it has everything we have been using, and as of now, everything is good with no deficiencies that need improvement. I think that Tomcat needs a more robust logging error details feature; the current logging feature is available, but it should be more user-friendly. This improvement would make error handling more user-friendly.

Quotes from Members

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

Pros

"The flexibility to create different services in different environments using IBM Open Liberty was important."

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

"The most valuable feature is the free EE server."

"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."

"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."

"It is a scalable platform."

"I love Tomcat for its scalability, reliability, availability, and steadiness."

"Web apps are very easy to deploy."

"The solution has very robust functionality."

"Tomcat brings the biggest benefit through its simplicity; it is not just simple in terms of interface, it is simple for managing or very quickly running this server."

More Tomcat pros

Cons

"To improve IBM Open Liberty, more integration with Kafka and message systems, and asynchronous messaging would be beneficial."

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

"It would be great if they offered more integration of monitoring tools."

"I think that Tomcat needs a more robust logging error details feature; the current logging feature is available, but it should be more user-friendly."

"The product needs to have more updates."

"This product needs an improvement to its centralized management console that can apply configurations and deployments for large scale clusters and groups of servers without the need of accessing each server to apply the changes."

"The product's pricing needs improvement."

"Deployment in Tomcat should be done through a GUI. We deploy applications from the backend using commands."

"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."

"Tomcat needs to improve its stability."

More Tomcat cons

Pricing and Cost Advice

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

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

"It is an open-source tool and is free of cost."

"There are no additional costs apart from the standard license."

"The price of the solution is good."

"This is an open-source product and it's free to use."

"It is an expensive product."

"Tomcat is an open-source server."
