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

"The integration between IBM tools and applications is very well executed."
"I find IBM support to be very nice."
"Starting with version 8, WAS provides a special folder called monitor deployment. Once you put the .war or .ear file in there, it is deployed automatically without human intervention. This greatly helps us in our continuous integration server. Once the deployment binary is ready, we write a script to copy it to that folder and then, voila! The application is up and running and accessible from its context root."
"I would say that the clustering, achieved by using the deployment manager, is valuable, as there is a load balancing feature that uses different nodes, handled by the deployment manager, and this functionality helps with the load balancing of applications."
"The VPN service is quite useful."
"The most valuable features are its user-friendliness and reliability in terms of application hosting."
"It does integrate well with the Tivoli Federated Identity Management system."
"It has good stability of the application server in the long term compared to other solutions."
"It is a robust solution."
"The ease of use of Tomcat is its most valuable feature. Once we grade particular software, we simply download it and we keep an eye on if Tomcat is working."
"The product's initial setup phase was simple."
"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's best feature is the open source server. It's a flexible and lightweight solution."
"I love Tomcat for its scalability, reliability, availability, and steadiness."
"Tomcat is a simple, light environment, whereas the full Red Hat Fuse solution is heavier."
"Tomcat has connectors like REST requests to connect the front end. Also, some parts of the inter-system communication go through REST. External connections with third parties occasionally involve both REST and SOAP protocols. Tomcat is versatile in accommodating these various communication methods."
 

Cons

"Sometimes, I feel WebSphere runs a bit slow. It might be loading unnecessary libraries, impacting its performance compared to other application servers."
"WebSphere is very cumbersome and not user-friendly. It used to have its own JVM, which presented challenges such as different architecture and memory leaks."
"In spite of the solution's robustness, it is expensive and a bit difficult to support."
"The solution consumes hardware."
"What could be improved in IBM WebSphere Application Server is its interconnection with other products, for example, Kafka. What I'd like to see in the next release of the solution is a better graphical user interface."
"The main issue we faced was its limited compatibility with non-Java technologies, which can result in difficulty detecting potential bugs and requiring additional integration efforts."
"The future of IBM WebSphere Application Server remains uncertain since it's based on Java 1.8 and Java 7."
"When we run into memory or locking issues, we resort to using third-party tools. However, it would be preferable to have native tools for debugging this type of problem."
"Tomcat's stability could be improved, especially when handling more memory-intensive, large-scale applications."
"I would also like to see a dashboard with some integrations in order to see the logs and trace performance easier."
"In the solution, we are using the terminal to enter command line codes for operations and management, this is difficult for me. It would be better if we had some administrator UI tools for this."
"Sometimes we face issues with the private and public networks and ensuring that once Tomcat is installed, that it is secure."
"Deployment in Tomcat should be done through a GUI. We deploy applications from the backend using commands."
"Tomcat is not user-friendly. I would also like to be able to have multiple applications run at the same time."
"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."
"The stability must be improved."
 

Pricing and Cost Advice

"The licensing policy is based on the PVU base."
"The pricing is a little expensive."
"IBM WAS base is part of the deal when you purchase IBM FileNet P8 Content Engine."
"The price of IBM WebSphere Application Server could be less expensive and there is an annual license required for this solution."
"It costs more than some of the others, but, you get what you pay for."
"The price of this product is higher than that of competitors."
"It is very expensive."
"We used to pay about $100,000-$120,000 US or somewhere around there. That was a bit cost-prohibitive for us to continue."
"This is an open-source product and it's free to use."
"Tomcat is an open source solution."
"The solution is open source so is free."
"It is an expensive product."
"Tomcat's pricing is very cheap."
"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."
"I give the pricing an eight out of ten."
"The price of the solution is good."
