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

"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."
"What's most valuable in IBM WebSphere Application Server is its resilience. When you use the solution, you know that after the communication has been done, there will be no doubt that the data has reached its destination."
"I find IBM support to be very nice."
"One of the most valuable features might be the stability of the IBM WebSphere Application Server."
"IBM WAS is extremely scalable. It is easy to add additional servers and to divide the load over servers in all kinds of ways."
"The integration between IBM tools and applications is very well executed."
"The product offers good performance."
"I love Tomcat for its scalability, reliability, availability, and steadiness."
"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."
"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."
"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 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."
"I find the quick startup valuable, particularly the static quick startup."
"The product is easy to use."
"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."
 

Cons

"The solution could improve the integration."
"The security could be better."
"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."
"The installation has room for improvement."
"The solution consumes hardware."
"In the next release of this solution, I would like to see support for the Arabic language."
"While WebSphere mostly supports IBM HTTP Server (IHS) as the web server plugin, I think it would be beneficial if it also supported Apache and NGINX web servers. That would give customers more flexibility in their choices."
"I think that this is a good product but I think that the cloud environment could be improved. I think that the future is in the utilization of the product in a product as a service way which is something that is lacking at this moment."
"The setup is complex and could be improved."
"Tomcat is not user-friendly. I would also like to be able to have multiple applications run at the same time."
"Vulnerability is one of the areas that can be considered an issue in the solution."
"It would be great if they offered more integration of monitoring tools."
"Resource configuration like JNDI and queue configuration, similar to other servers, should be provided from the admin console for Tomcat."
"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."
"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."
"I would personally like it if the admin console would show more information specifically about memory being used."
 

Pricing and Cost Advice

"We pay around $200,000 annually."
"WebSphere Application Server is expensive, so it may not be a good option for small companies."
"I don't remember the price, but there are no additional costs."
"The solution is quite expensive."
"It costs more than some of the others, but, you get what you pay for."
"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 licensing cost is 1,000 of euros for a 30-year table."
"It is very expensive."
"The tool is free."
"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."
"The solution is free."
"Tomcat is not costlier than other solutions."
"We are using the open-source version."
"Tomcat is an open-source server."
"This is an open-source product and it's free to use."
"Tomcat is an open source solution."
