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.

Improved on-premise performance has supported faster, secure apps and clearer server monitoring
One thing I appreciate most about Windows Server AppFabric is because it's widely used; it's easier to get solutions online from other communities when I am stuck. Because it is widely used, it's easier to get solutions and also easier to work with. Especially after I found 2019, I have worked with 2019 and I appreciate it. It's easier to get solutions. After implementing Windows Server AppFabric, I can say I love the speed. The functionality and speed are good. Earlier, when they added more people, I could see some lagging. But now, I have no issue even if I double the users, even if I add 30% of users or any applications, it will still be fast. It increased the speed and also security. I've noticed the new one I have is good and secure. I love the security. The monitoring capabilities of Windows Server AppFabric help me improve service visibility and troubleshooting. In a day, I have to go through a lot of the logs and also the utilization. There, I see the CPU. I have to do the utilization, and I can see what is utilizing the most. By doing this, I can be able to tell what, in case I need to do an upgrade, what I might need to provide the upgrade or maybe increase in users that will not affect the operations.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"They offer good help to help resolve the issue."
"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."
"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."
"I would not compare WebSphere and WebLogic because both servers are really good."
"As compared to other applications, it has tremendous support. We have built internal capability so that we use it extensively internally. It is also easier to use with the outside data. You can write in ESQL, Java, or any other technology that you want to use for development. So, it is a lot more flexible in the language that it supports."
"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."
"WebSphere Application Server's best features include the data subscription and connection viewer."
"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."
"This product works great for us and it's unfortunate that they're not going to support it anymore."
"The product's deployment phase was very easy."
"The most valuable feature is AppFabric's hosting solution, which is what we need for running workflows."
"The ability to seamlessly deploy, image, and patch without causing downtime is extremely helpful and user-friendly."
"After implementing Windows Server AppFabric, I can say I love the speed."
"It is very usable and easy to understand, and antivirus and VPN are the main features being used now, allowing my clients to access the network from home, which was very crucial because of the pandemic."
 

Cons

"In the next release of this solution, I would like to see support for the Arabic language."
"The solution could improve the integration."
"IBM WebSphere Application Server hasn't changed much. It's still a heavyweight for any company compared to what you get. Unless your code base is deeply linked with it, I don't think it's a great idea to go with this solution. The current trend is toward modularity and containerization, and given the product's requirements, containerization will be difficult. There is a memory requirement as well."
"Its price is a bit expensive. They should improve its price to compete with other applications that are out there, which we are also exploring."
"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 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."
"In spite of the solution's robustness, it is expensive and a bit difficult to support, which is why companies nowadays tend to use more lightweight products such as Tomcat or cloud versions of the products."
"Stability is frustrating. It goes down after a specific number of user connections."
"Its price and licensing policy can be improved. It could be a little cheaper. Licensing is sometimes confusing. There are so many different options. It is difficult to find out what to buy or what to choose for my necessity."
"Microsoft will stop supporting the product next year, and we can't run unsupported programs in our systems."
"The product is unable to connect with different cloud services."
"The most important issue I've found is the blue screen errors, particularly when customers use external displays with a P-type cable."
 

Pricing and Cost Advice

"There is an Eclipse Plugin provided by IBM, so no need to buy IBM Rational Application Developer or Rational Software Architect tools."
"The pricing is a little expensive."
"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."
"We pay around $200,000 annually."
"IBM WAS base is part of the deal when you purchase IBM FileNet P8 Content Engine."
"It costs more than some of the others, but, you get what you pay for."
"When you purchase Maximo, you get WebSphere for free."
"It's expensive."
"It is expensive, and its licensing is a bit confusing."
"The product is affordable, in my opinion."
