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 scalability of the product is quite good."
"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."
"Security: It is compatible with the latest Java 8 security features, supports FIPS 140-2 and NIST SP 800-53 with strong ciphers and cryptography keys, and supports TLS 1.2 completely. Also, configuring client and server certificates is relatively easy."
"The solution has good performance."
"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."
"The thing about WebSphere, as opposed to other ones that I am aware of such as JBoss and Liberty, is that WebSphere has the most comprehensive scaffolding available to it."
"The only reason why we're currently using WebSphere is that the integration of the authentication with Azure is very quick. WebSphere has something that can immediately connect with Azure Active Directory."
"The product offers good performance."
"Tomcat is reliable and secure, which makes it valuable for our application deployment."
"Tomcat is secure, reliable, and stable."
"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."
"The product's most valuable feature is the ability to host applications."
"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."
"I love Tomcat for its scalability, reliability, availability, and steadiness."
"Tomcat's best feature is the open source server. It's a flexible and lightweight solution."
"The most valuable feature of Tomcat is its ability to export libraries into different instances so that I can use it not only in one application but in multiple applications."
 

Cons

"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 solution could improve the integration."
"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."
"In spite of the solution's robustness, it is expensive and a bit difficult to support."
"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."
"The current trend is to move to Liberty because of the portability of its cloud and its Kubernetes, which containerize the application."
"The licensing could be improved, and I would like it to give the longevity of the lifespan of the visions. In the next release, I would like to be able to download and extract the files so that I can just use my application server."
"They should make the solution more lightweight and not bundle everything into a single product."
"I would personally like it if the admin console would show more information specifically about memory being used."
"It would be great if they offered more integration of monitoring tools."
"Java functions should be built better into the solution."
"Technical support is limited."
"Tomcat needs to improve its stability."
"Tomcat is a polished product that has been around for a long time. It should be simple and high-performing, with the ability to grow and maintain stability. The fewer features it has, the more stable it will be."
"Tomcat lacks a visual tool for configuring."
"Tomcat is not user-friendly. I would also like to be able to have multiple applications run at the same time."
 

Pricing and Cost Advice

"WebSphere Application Server is expensive, so it may not be a good option for small companies."
"We pay around $200,000 annually."
"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."
"Room for improvement would only be in the licensing. As with all IBM products the licensing can be complex and expensive. Bargain well and try to get as much discount as possible. Discounts of 85% are possible. Without the discount, I think the product is overrated."
"When you purchase Maximo, you get WebSphere for free."
"The price of this product is higher than that of competitors."
"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."
"IBM WAS base is part of the deal when you purchase IBM FileNet P8 Content Engine."
"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."
"We are currently using the open-source version."
"Tomcat is open-source and free to use."
"There are no additional costs apart from the standard license."
"The solution is free."
"Tomcat is an open-source server."
"Tomcat is not costlier than other solutions."
"It is an expensive product."
