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 scalability of the product is quite good."
"The most valuable feature of this solution is Portal Virtualization."
"IBM WAS is extremely scalable. It is easy to add additional servers and to divide the load over servers in all kinds of ways."
"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."
"Without the Admin Console it would be very hard to configure JVM settings, JDBC datasources, mail session settings, and security providers."
"The most valuable features are its user-friendliness and reliability in terms of application hosting."
"The VPN service is quite useful."
"Ease of use, the richness of the libraries and basically very good development tools."
"In-built refactoring and .Net profilers are the most valuable features of the solution."
"It is a stable solution."
"Microsoft .NET Framework’s most valuable features are web application development, RESTful services development, security, performance, and less memory footprint."
"I'd rate the solution as highly stable."
"The .NET Framework is a very good framework. It does what I need it to do."
"The solution is not limited in storage, is customizable and simple to use."
"It's easy to create and integrate things."
 

Cons

"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."
"They should make the solution more lightweight and not bundle everything into a single product."
"Installing or configuring a WAS server instance as a Windows Service causes a lot of problems, especially when the server needs credentials to stop."
"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 future of IBM WebSphere Application Server remains uncertain since it's based on Java 1.8 and Java 7."
"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."
"Sometimes, I feel WebSphere runs a bit slow. It might be loading unnecessary libraries, impacting its performance compared to other application servers."
"The solution consumes hardware."
"There is room for Microsoft .NET Framework to improve cloud platform capabilities."
"The product's price is an area of concern, making it an area where improvements are required."
"The product is nearing its sunset, and we think that by 2028, we won't get support anymore"
"The integration with DevOps tools, such as Azure DevOps, Jira, and GitLab, would be a valuable addition."
"The significant challenge is that you need an enterprise-level company to maintain software in Microsoft .NET Framework with a proper structure."
"Difficult to scale this product for large organizations."
"This solution is best used with some training."
"It would be nice if the framework were able to work with additional environments and systems like Linux."
 

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."
"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."
"The price of this product is higher than that of competitors."
"The pricing is a little expensive."
"When you purchase Maximo, you get WebSphere for free."
"It is very 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."
"The solution is a bit costly when compared to open source products or open gear licenses."
"We have an annual license, and we pay extra for extended support."
"Microsoft .NET Framework is a free, open-source solution."
"The Microsoft .NET Framework is free of charge, without licensing cost."
"There is a Community Edition that can be used free of charge, but the licensing cost for the Enterprise version is quite high."
"The pricing could be cheaper."
"For the moment I can only give the product a rating of five out of ten since only some of the customers will be satisfied, those that have the financial resources for hosting a platform on Windows Server."
"If you want to develop an enterprise-level application, you have to purchase the enterprise-level development license."
