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

"The integration between IBM tools and applications is very well executed, and the support from IBM is quite good, providing a solid support structure."

"I would not compare WebSphere and WebLogic because both servers are really good."

"It has helped tremendously."

"Once you deploy your application, it will be very stable with no issues at all."

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

"The solution is robust, and the connection management and the scalability which IBM provides to the stack are also valuable."

"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."

"It does integrate well with the Tivoli Federated Identity Management system."

More IBM WebSphere Application Server pros

"The technology is very scalable and accessible to use."

"It facilitates running Windows business applications and leveraging enterprise application development."

"The solution has assisted our organization in the full-stack development process. The tool can be deployed on all types of devices, including mobiles and desktops. The MAUI capabilities of the solution have been the most beneficial feature for our organization's development needs."

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

"The .NET Framework is a very good framework. It does what I need it to do."

"In my opinion, the best thing about Microsoft .NET is the fully featured framework. It provides most of the things which a normal developer requires of any application out of the box."

"The way Microsoft adapted to the corporate customers, offered stability and scalability, and also the quality of support were some of the reasons we switched."

"Basically, .NET is simply is the easiest programming language to use, based on my experience."

More Microsoft .NET Framework pros

Cons

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

"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)."

"The availability of the solution needs improvement. The product should be more enhanced and responsive."

"Stability is frustrating. It goes down after a specific number of user connections."

"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."

"The current trend is to move to Liberty because of the portability of its cloud and its Kubernetes, which containerize the application."

"The installation is not straightforward and it can take three days."

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

More IBM WebSphere Application Server cons

"The pricing is a bit expensive."

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

"I would like more web integration."

"The product is nearing its sunset, and we think that by 2028, we won't get support anymore"

"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."

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

"The runtime environment for ASP.NET needs improvement to make it more universal."

"They should have more training materials available that are specific to .NET. We spend a lot of money training our engineers."

More Microsoft .NET Framework cons

Pricing and Cost Advice

"It's expensive."

"WebSphere Application Server is expensive, so it may not be a good option for small companies."

"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."

"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 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."

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

More IBM WebSphere Application Server pricing and cost advice

"We have an annual license, and we pay extra for extended support."

"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."

"The solution is a bit costly when compared to open source products or open gear licenses."

"The pricing could be cheaper."

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

"Microsoft .NET Framework is free of cost."

"Do your homework. Consider the partnership program."

"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."
