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

"We have about 3,000 users concurrently using this application, and it has achieved more than 99.9% up time which has resulted in increased productivity and efficiency."

"IBM WebSphere Application Server is the ultimate product; there is nothing superior to IBM WebSphere Application Server, and while there are other options such as Tomcat, JBoss, and Oracle's solution, IBM WebSphere Application Server stands above them all."

"IBM WAS is the backbone for our enterprise content management suite which delivers the primary processes for our customers."

"The thing about WebSphere, as opposed to other ones that I am aware of such as JBoss and Liberty, is that WebSphere has the most comprehensive scaffolding available to it."

"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."

"Without the Admin Console it would be very hard to configure JVM settings, JDBC datasources, mail session settings, and security providers."

"IBM WebSphere Application Server works well and fulfills all of the requirements that are demanded of it, so it is a product that I recommend."

"They offer good help to help resolve the issue."

More IBM WebSphere Application Server pros

"A great solution for creating program solutions in a framework for Microsoft Windows quickly and easily."

"It facilitated the streamlined scheduling process by amalgamating inputs from various sources, including location data and other systems."

"The Microsoft .NET Framework is 100% stable."

"Microsoft has tested the solution and our experience with it has shown us that, while it is not as fast as some of our other software-devoted platforms, it is very stable."

"The solution is not limited in storage, is customizable and simple to use."

"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's easy to create and integrate things."

More Microsoft .NET Framework pros

Cons

"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."

"The solution could improve the integration."

"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."

"The installation has room for improvement."

"The solution is very expensive compared to an open-source stack."

"The solution consumes hardware."

"WebSphere is very cumbersome and not user-friendly."

"Initial setup is very simple. Just use the IBM Installation Manager and add the packages. The install wizard takes care of the rest. The only thing that can be difficult is to find the right packages on the IBM website, because of all the changes that IBM does on its website(s)."

More IBM WebSphere Application Server cons

"The pricing and support have room for improvement. The pricing is too high currently."

"I would recommend Magic rather than .NET. It takes longer to develop something on .NET."

"Lacking in auto-scaling."

"The solution needs to update its security periodically because there are many security concerns."

"You need to have the technical expertise to use this product."

"Microsoft .NET Framework servers have historically been more targeted by hackers and viruses compared to Linux, Unix, or Sun Solaris servers."

"I would like to see more pre-built features in the MVC framework because as it is now, it's very open and you have to develop your own controls in order to use it."

"Some cloud features will not run in an old version of Microsoft .NET Framework easily or at all. Running on the cloud is complex."

More Microsoft .NET Framework cons

Pricing and Cost Advice

"Room for improvement would only be in the licensing. As with all IBM products the licensing can be complex and expensive. Bargain well and try to get as much discount as possible. Discounts of 85% are possible. Without the discount, I think the product is overrated."

"The solution is quite expensive."

"There is an Eclipse Plugin provided by IBM, so no need to buy IBM Rational Application Developer or Rational Software Architect tools."

"We pay around $200,000 annually."

"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."

"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."

"It is very expensive."

More IBM WebSphere Application Server pricing and cost advice

"Microsoft .NET Framework is very cost-effective for corporate users."

"Microsoft .NET Framework is free of cost."

"The product is not expensive."

"Microsoft .NET Framework is licensed under the Windows License."

"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."

"Do your homework. Consider the partnership program."

"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."

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