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.

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

"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."
"IBM WebSphere Application Server is one of the best servers due to its stability and paid license."
"One of the most valuable features might be the stability of the IBM WebSphere Application Server."
"The performance is good."
"The VPN service is quite useful."
"This solution is easy to use with a GUI that is intuitive and very helpful."
"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."
"I find IBM support to be very nice."
"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 product has a good interface and easy-to-use programming language."
"Developing APIs, services, and GUIs are done easily; tasks that might take three to four days with bare metal Microsoft .NET Framework can be completed in four to eight hours with ABP.io, depending on complexity."
"The solution's technical support is very good...The product's initial setup phase was easy."
"Ease of use, the richness of the libraries and basically very good development tools."
"The .NET framework is a mature platform that is very helpful and saves time during the software development process."
"For us, it is better to remain under the umbrella of Microsoft."
"When it comes to the user interface, the context is better than other tools because it is easier to use."
 

Cons

"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 availability of the solution needs improvement."
"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."
"WebSphere is very cumbersome and not user-friendly."
"In spite of the solution's robustness, it is expensive and a bit difficult to support."
"WebSphere Application Server doesn't have an automated deployment option, forcing us to use third-party tools like Jenkins UCD and Palo Automated Deployment."
"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."
"Based on the field and based on the build that was provided, we've noticed a lot of constraints in terms of the performance now."
"The .NET open source community could be larger."
"The product's price is an area of concern, making it an area where improvements are required."
"The pricing is a bit expensive."
"There is room for Microsoft .NET Framework to improve cloud platform capabilities."
"Microsoft has its own product called Blazor, but I don't think it's quite as powerful yet as React or Angular. That's an area for improvement."
"Like in C#, Microsoft .NET Framework should provide code reusability options for all kinds of development processes."
"I would want the product to be integrated with the different AI tools in the future since it is one of the areas where the product has certain shortcomings."
"The solution needs to update its security periodically because there are many security concerns."
 

Pricing and Cost Advice

"We pay around $200,000 annually."
"It costs more than some of the others, but, you get what you pay for."
"It's expensive."
"The solution is quite 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."
"The licensing policy is based on the PVU base."
"The price of IBM WebSphere Application Server could be less expensive and there is an annual license required for this solution."
"The price of this product is higher than that of competitors."
"Microsoft .NET Framework is licensed under the Windows License."
"Microsoft .NET Framework is very cost-effective for corporate users."
"Considering the bigger picture, opting for the Microsoft ecosystem can be beneficial and it is priced well. When relying on entirely open-source solutions, you may encounter challenges associated with dealing with multiple vendors and potentially compromised security measures. However, it is important to note that Microsoft could enhance its performance when it comes to addressing critical security concerns."
"In the interim, there's no need to purchase videos for viewing. Microsoft has made significant moves in the .NET space, starting with their response in Visual Studio Code and now providing Visual Studio entirely for free. This is a notable shift from the past when we used to pay substantial amounts for technical subscriptions. Previously, a group of ten developers could cost several thousand dollars annually for licensing. However, the current trend is to offer these tools for free to maintain their dominance in the developer market. The market dynamics have changed, and now developers can freely download Visual Studio, making it a preferred choice over other paid options."
"There is a Community Edition that can be used free of charge, but the licensing cost for the Enterprise version is quite high."
"The product is not expensive."
"We have an annual license, and we pay extra for extended support."
"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."
