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

"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."

"The most valuable feature of this solution is Portal Virtualization."

"It is very stable, safe, and secure."

"The most valuable features are its user-friendliness and reliability in terms of application hosting."

"This solution is very good in terms of stability."

"It has helped tremendously."

"One of the most valuable features might be the stability of the IBM WebSphere Application Server."

"The performance is good."

More IBM WebSphere Application Server pros

"Microsoft .NET Framework has introduced many new features, making the technology very vast."

"The solution is easy to use."

"Microsoft .NET Framework’s most valuable features are web application development, RESTful services development, security, performance, and less memory footprint."

"It is a stable solution."

"The most valuable thing about Microsoft .NET Framework is that it is an enterprise-grade language and platform."

"The .NET Framework is easier to use because it provides a wide range of libraries."

"Proven solution with valuable customization."

"The tool offers a lot of support, and there is a lot of knowledge material available, along with a lot of community groups."

More Microsoft .NET Framework pros

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."

"When compared with WebLogic, Weblogic is lighter and consumes less memory."

"Since we've been monitoring it directly ourselves, we've found that there has been an increase in the number of failures. The failures result in deadlock processes that generate very little to no troubleshooting logs."

"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 security could be better."

"IBM needs to pay attention to market changes more quickly. We now have Java 9 and very soon Java EE8. We do not want to wait for two or three years after their release until they are supported by the new version."

"I think IBM WebSphere Application Server is a dead solution and will probably fade out."

More IBM WebSphere Application Server cons

"The price of the Enterprise version is quite high and can be improved."

"One thing that could improve Microsoft .NET Framework is to give it more flexibility."

"Like in C#, Microsoft .NET Framework should provide code reusability options for all kinds of development processes."

"This solution is best used with some training."

"I would like more web integration."

"I would like to see a better response time from the technical support."

"The cloud features must be improved."

"The learning curve could be improved."

More Microsoft .NET Framework cons

Pricing and Cost Advice

"I don't remember the price, but there are no additional costs."

"When you purchase Maximo, you get WebSphere for free."

"The price of this product is higher than that of competitors."

"The solution is quite 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."

"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."

"IBM WAS base is part of the deal when you purchase IBM FileNet P8 Content Engine."

"It's expensive."

More IBM WebSphere Application Server pricing and cost advice

"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."

"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."

"Microsoft .NET Framework is a free, open-source solution."

"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."

"There is a Community Edition that can be used free of charge, but the licensing cost for the Enterprise version is quite high."

"The Microsoft .NET Framework is free of charge, without licensing cost."

"It's an expensive solution"
