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."

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

"The scalability of the product is quite good."

"As compared to other applications, it has tremendous support. We have built internal capability so that we use it extensively internally. It is also easier to use with the outside data. You can write in ESQL, Java, or any other technology that you want to use for development. So, it is a lot more flexible in the language that it supports."

"Starting with version 8, WAS provides a special folder called monitor deployment. Once you put the .war or .ear file in there, it is deployed automatically without human intervention. This greatly helps us in our continuous integration server. Once the deployment binary is ready, we write a script to copy it to that folder and then, voila! The application is up and running and accessible from its context root."

"IBM WebSphere Application Server is one of the best servers due to its stability and paid license."

"WebSphere Application Server's best features include the data subscription and connection viewer."

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

More IBM WebSphere Application Server pros

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

"It is easy to use, and it runs on a Windows platform."

"As we are a software company, we find that accessing resources using this technology is easier compared to the others."

"It's easy to create and integrate things."

"Microsoft Platform is the only viable solution when I wish to do something that is not supposed to be cross-platform."

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

"The solution is user-friendly and straightforward."

More Microsoft .NET Framework pros

Cons

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

"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."

"WebSphere Application Server doesn't have an automated deployment option, forcing us to use third-party tools like Jenkins UCD and Palo Automated Deployment."

"The footprint could be reduced so that we can use a smaller virtual machine to run the application. We could also use more scripts. I would like this solution to be more script oriented, rather than GUI oriented."

"Its price is a bit expensive. They should improve its price to compete with other applications that are out there, which we are also exploring."

"Installing or configuring a WAS server instance as a Windows Service causes a lot of problems, especially when the server needs credentials to stop."

"Some things are very difficult to do, so the interface and usage could be more intuitive for those."

"The installation has room for improvement."

More IBM WebSphere Application Server cons

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

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

"They should try to improve their Blazor WebAssembly."

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

"They do provide the .NET library, however, for me, the most important capability we want to investigate in the future is the integration with Copilot."

"The integration with DevOps tools, such as Azure DevOps, Jira, and GitLab, would be a valuable addition."

"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."

"Microsoft could improve .NET Framework by providing more resources to help users understand the solution."

More Microsoft .NET Framework cons

Pricing and Cost Advice

"We pay around $200,000 annually."

"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."

"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."

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

"The price of IBM WebSphere Application Server could be less expensive and there is an annual license required for this solution."

"It costs more than some of the others, but, you get what you pay for."

"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."

More IBM WebSphere Application Server pricing and cost advice

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

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

"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."

"The pricing could be cheaper."

"The product and support for this solution are free for everyone."

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

"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."
