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.

Has enabled building responsive multi-threaded applications while supporting rapid deployment workflows
Microsoft .NET Framework has already made significant improvements by becoming open source. Many developers are contributing to Microsoft .NET Framework, not just Microsoft itself. They have ported it to many platforms and allow a healthy ecosystem of open source tools. They have moved from Visual SourceSafe to supporting Git with Microsoft Visual Studio. Their IDE, Visual Studio Code, is open source and multi-platform. There are many third-party tools available, including AI-based tools such as Cursor and Bolt, which are forks of Visual Studio Code. Based on my understanding, I don't have any suggestions for improvement as they are already doing an excellent job.

Quotes from Members

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

Pros

"High availability, alert management, and deployments are the most valuable features for us. We have the ND version so we can do deployments."
"We needed this type of integration and WebShepere is the best tool for it."
"It has good stability of the application server in the long term compared to other solutions."
"The solution is very stable and robust."
"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."
"Network Deployment is the most useful feature for scalability. It has many features within the standard WebSphere Application Server edition."
"WebSphere Application Server's best features include the data subscription and connection viewer."
"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."
"Proven solution with valuable customization."
"The solution is easy to use."
"When it comes to the user interface, the context is better than other tools because it is easier to use."
"Microsoft Platform is the only viable solution when I wish to do something that is not supposed to be cross-platform."
"If we take low code, no code platform such as RPA platforms, you might end up writing 100 lines of code and you might do it in a single line of code using. NET."
"The Windows Communication Foundation is the biggest advantage we get from the .NET Framework."
"As we are a software company, we find that accessing resources using this technology is easier compared to the others."
"The APIs are completely effective."
 

Cons

"In spite of the solution's robustness, it is expensive and a bit difficult to support."
"The solution could improve the integration."
"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."
"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 solution consumes hardware."
"The main issue we faced was its limited compatibility with non-Java technologies, which can result in difficulty detecting potential bugs and requiring additional integration efforts."
"Installing or configuring a WAS server instance as a Windows Service causes a lot of problems, especially when the server needs credentials to stop."
"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."
"Their system is very vast. I have spent 12 years here, and I can definitely say there is still a lot of scope for improvement."
"It would be nice if the framework were able to work with additional environments and systems like Linux."
"There are performance constraints when multiple users are accessing the application and that consumes CPU resources."
"Difficult to scale this product for large organizations."
"Needs stronger security with respect to cloud issues."
"The cloud features must be improved."
"They should try to improve their Blazor WebAssembly."
"Lacking in auto-scaling."
 

Pricing and Cost Advice

"The licensing policy is based on the PVU base."
"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 IBM WebSphere Application Server could be less expensive and there is an annual license required for this solution."
"The licensing cost is 1,000 of euros for a 30-year table."
"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."
"The solution is quite expensive."
"The price of this product is higher than that of competitors."
"The support is an extra cost when purchasing the license. The price of the solution is overall reasonable and paid annually or every three years. Additionally, they have a monthly license. The cost is approximately $1,000 per user."
"I rate the solution's pricing a two out of ten because .NET is an open-source framework. You don't have to pay for a license."
"The solution is free but you need to pay for a license for the hosting service."
"The product is not expensive."
"We have an annual license, and we pay extra for extended support."
"Microsoft .NET Framework is free of cost."
"The pricing could be cheaper."
"If you want to develop an enterprise-level application, you have to purchase the enterprise-level development license."
