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.

We use the solution for web services.
It would be good to enhance the schedule interface. There is no indication that lets us know if a module has stopped. Shortly speaking, each business host has color in the Production page. Meanings of colors are described in a "Legend" link on the Production page. Also, each business host either has or has no private pool (processes that work with its queues). When we stop a business host by scheduling, its private processes are killed (if they exist). Such a situation is not expressed in changing business host color. The only way to check if a business host is stopped by scheduling is to check its processes presence.

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."
"Once you deploy your application, it will be very stable with no issues at all."
"The solution has good performance."
"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."
"We have about 3,000 users concurrently using this application, and it has achieved more than 99.9% up time which has resulted in increased productivity and efficiency."
"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 solution is robust, and the connection management and the scalability which IBM provides to the stack are also valuable."
"The product offers good performance."
"The InterSystems technical support (WRC) is perfect and highly qualified."
 

Cons

"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."
"WebSphere is very cumbersome and not user-friendly."
"The business logic side of it is sort of missing in the sense that if I want to track and measure velocity, it is not really available. You have to buy another application and embark on a separate implementation. Instead of having different licensing, IBM DataPower should be integrated with WebSphere. It will allow us to build the business layer and rules a lot more efficiently, rather than developing rules within the application. It would be good if we can set up the business layer through parametrization rather than development. IBM DataPower has the business rule and the controls, and if it can be integrated, it would be fantastic. It will help the application in working better in terms of security features and business logic. If you're going to use it for open banking, you will be able to monitor velocity on the total pricing."
"Stability is frustrating. It goes down after a specific number of user connections."
"The solution consumes hardware."
"The current trend is to move to Liberty because of the portability of its cloud and its Kubernetes, which containerize the application."
"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 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."
"It would be good to enhance the schedule interface."
 

Pricing and Cost Advice

"The price of IBM WebSphere Application Server could be less expensive and there is an annual license required for this solution."
"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."
"I don't remember the price, but there are no additional costs."
"There is an Eclipse Plugin provided by IBM, so no need to buy IBM Rational Application Developer or Rational Software Architect tools."
"The price of this product is higher than that of competitors."
"It costs more than some of the others, but, you get what you pay for."
"It is very expensive."
"WebSphere Application Server is expensive, so it may not be a good option for small companies."
