Executive SummaryUpdated on Feb 2, 2025

IBM WebSphere Application Server and Tomcat compete in the enterprise application server market. IBM WebSphere seems to have an edge in enterprise environments due to its comprehensive support and features, while Tomcat is preferred in smaller implementations for its simplicity and cost-effectiveness.

Features: IBM WebSphere boasts robust security, transaction management, and high scalability, making it suitable for complex enterprise applications. Tomcat is lightweight and easily configurable, ideal for developers seeking portability and simplicity. Tomcat's integration capabilities with existing systems are also valuable.

Room for Improvement: IBM WebSphere could improve in easing the deployment process and reducing its complexity for smaller teams. Tomcat might enhance its support for enterprise-level features and client management tools. Better documentation and automation capabilities could enhance both tools.

Ease of Deployment and Customer Service: Tomcat offers a simple deployment process ideal for smaller teams, with extensive community support. IBM WebSphere, while more complex, provides comprehensive customer service that assists larger organizations with setup and maintenance.

Pricing and ROI: IBM WebSphere involves higher setup costs but offers higher ROI for enterprise-level implementations with its extensive feature set and support. Tomcat, being open source, presents minimal setup costs, making it attractive for small to medium businesses with budget constraints and fast ROI goals.

Has worked seamlessly in complex clustered environments and supports long-term development efforts

IBM WebSphere Application Server is currently at version 9.0.5.23. In recent months, they released fix 23, as they periodically release fixes. Previously, they frequently increased versions, but now they maintain 9.0.5 with different releases. It's based on Java J2EE 7 and Java SDK 1.8. Oracle announced that 2030 will be the last year when Java SDK 1.8 will be supported. Oracle currently deploys Java 2.x in parallel, with the latest being version 25. The future of IBM WebSphere Application Server remains uncertain since it's based on Java 1.8 and Java 7. I haven't found any white papers or official documentation from IBM outlining their trajectory post-2030.

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

"High availability, alert management, and deployments are the most valuable features for us. We have the ND version so we can do deployments."

"It's an awesome solution. Compared to everything else that's out there in the market right now, IBM MQ is hands down the best solution available and that's based on 40 years of IT experience."

"IBM WAS is the backbone for our enterprise content management suite which delivers the primary processes for our customers. Without a good application server, it would be hard to provide a secure layer of midddleware upon which the other applications run. IBM WAS improves the stability of the entire solution and provides a high quality platform for running web-based solutions."

"It integrates well with the Tivoli Federated Identity Management system, which works as a single sign-on mechanism for other e-services that we have shared with other clients."

"WebSphere Application Server's best features include the data subscription and connection viewer."

"Network Deployment is the most useful feature for scalability. It has many features within the standard WebSphere Application Server edition."

"The scalability of the product is quite good."

"The solution is robust, and the connection management and the scalability which IBM provides to the stack are also valuable."

More IBM WebSphere Application Server pros

"The product is easy to use."

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

"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 is one of the best application servers and servlet container."

"Web apps are very easy to deploy."

"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 recommend using Apache Tomcat due to its open-source nature, lightweight design, and ease of installation and configuration."

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

More Tomcat pros

Cons

"I think IBM WebSphere Application Server is a dead solution and will probably fade out."

"The current trend is to move to Liberty because of the portability of its cloud and its Kubernetes, which containerize the application."

"I think in some moments, the security was a little bit more complex to configure when it was delegated to other systems, making it an area where improvements are required."

"The footprint could be reduced so that we can use a smaller virtual machine to run the application. We could also use more scripts. I would like this solution to be more script oriented, rather than GUI oriented."

"The future of IBM WebSphere Application Server remains uncertain since it's based on Java 1.8 and Java 7."

"I would note that the response time is something IBM's support team needs to improve."

"The solution consumes hardware."

"Installing or configuring a WAS server instance as a Windows Service causes a lot of problems, especially when the server needs credentials to stop."

More IBM WebSphere Application Server cons

"I have no recommendations for improvements."

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

"Tomcat is not always stable and but I have not used another server yet to compare the overall stability."

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

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

"The setup is complex and could be improved."

"The product's pricing needs improvement."

"Tomcat needs to improve its stability."

More Tomcat cons

Pricing and Cost Advice

"The pricing is a little expensive."

"The price of IBM WebSphere Application Server could be less expensive and there is an annual license required for this solution."

"It is very expensive."

"My company is on a perpetual or permanent license agreement with IBM WebSphere Application Server. There's also a pay-per-use option, but customers rarely choose that option. Most of the customers are on the perpetual license deal that's all-inclusive. As the license cost is quite expensive, I'm rating it two out of five."

"If your application is just a web app that does not need to scale big, you can obtain a single core license of WAS Express edition, which has almost the same features with limited processing cores. If you manage a very big application farm (i.e. need to run 10 or more WAS servers) it is better to get IBM WAS Hypervisor Edition."

"The price of this product is higher than that of competitors."

"There is an Eclipse Plugin provided by IBM, so no need to buy IBM Rational Application Developer or Rational Software Architect tools."

"It's expensive."

More IBM WebSphere Application Server pricing and cost advice

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

"Tomcat is not costlier than other solutions."

"We are currently using the open-source version."

"Tomcat is an open source solution."

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

"The price of the solution is good."

"Tomcat's pricing is very cheap."

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