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

"The most valuable feature of this solution is Portal Virtualization."
"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."
"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 scalability of the product is quite good."
"WebSphere Application Server's best features include the data subscription and connection viewer."
"Ease of administration: It has an Integrated Solutions Console, what we call the administrative console, with very detailed configurations and Help pages for each configurable item."
"The solution is robust, and the connection management and the scalability which IBM provides to the stack are also valuable."
"Network Deployment is the most useful feature for scalability. It has many features within the standard WebSphere Application Server edition."
"This product works great for us and it's unfortunate that they're not going to support it anymore."
"The most valuable feature is AppFabric's hosting solution, which is what we need for running workflows."
"The product's deployment phase was very easy."
"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."
"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."
 

Cons

"I think in some moments, the security was a little bit more complex to configure when it was delegated to other systems, making it an area where improvements are required."
"Room for improvement would only be in the licensing. As with all IBM products the licensing can be complex and expensive."
"The installation has room for improvement."
"In the next release of this solution, I would like to see support for the Arabic language."
"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."
"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."
"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."
"WebSphere is very cumbersome and not user-friendly."
"The product is unable to connect with different cloud services."
"Microsoft will stop supporting the product next year, and we can't run unsupported programs in our systems."
"The most important issue I've found is the blue screen errors, particularly when customers use external displays with a P-type cable."
"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."
 

Pricing and Cost Advice

"The pricing is a little expensive."
"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."
"We used to pay about $100,000-$120,000 US or somewhere around there. That was a bit cost-prohibitive for us to continue."
"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."
"It's expensive."
"There is an Eclipse Plugin provided by IBM, so no need to buy IBM Rational Application Developer or Rational Software Architect tools."
"The licensing cost is 1,000 of euros for a 30-year table."
"It is very expensive."
"It is expensive, and its licensing is a bit confusing."
"The product is affordable, in my opinion."
