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 WAS is the backbone for our enterprise content management suite which delivers the primary processes for our customers. Without a good application server, it would be hard to provide a secure layer of midddleware upon which the other applications run. IBM WAS improves the stability of the entire solution and provides a high quality platform for running web-based solutions."
"WebSphere Application Server is very stable."
"It has good stability of the application server in the long term compared to other solutions."
"Network Deployment is the most useful feature for scalability. It has many features within the standard WebSphere Application Server edition."
"IBM WAS is extremely scalable. It is easy to add additional servers and to divide the load over servers in all kinds of ways."
"IBM WebSphere Application Server is the best in terms of scalability and performance, as well as the support for managing distributed transactions."
"IBM WAS is the backbone for our enterprise content management suite which delivers the primary processes for our customers."
"It facilitated the streamlined scheduling process by amalgamating inputs from various sources, including location data and other systems."
"Given that it's cross-platform right now, where you can use it on Windows and Mac, that is the single most significant feature that has resulted in wider adoption of .NET."
"As we are scaling quite nicely on Azure."
"The most valuable feature is the financial accounting."
"The solution is user-friendly and straightforward."
"I like that ASP.NET is used for the framework and the core web services."
"The technology is very scalable and accessible to use."
"When we talk about .NET development, we use Visual Studio IDE to create these things. In recent years, there have been a lot of improvements in Visual Studio 2022. It would be a daunting task to list all of the features that have benefited us, as it would require a lot of time and effort. However, there are definitely many improvements year after year in .NET development."
 

Cons

"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."
"The future of IBM WebSphere Application Server remains uncertain since it's based on Java 1.8 and Java 7."
"The licensing could be improved, and I would like it to give the longevity of the lifespan of the visions. In the next release, I would like to be able to download and extract the files so that I can just use my application server."
"While WebSphere mostly supports IBM HTTP Server (IHS) as the web server plugin, I think it would be beneficial if it also supported Apache and NGINX web servers. That would give customers more flexibility in their choices."
"As the license cost is quite expensive, I'm rating it two out of five."
"I'd like to see the ability to build clusters made a little bit easier. It is kind of a manual process right now and this would just help save time and reduce resources."
"The security could be better."
"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 main obstacle in this technology is that it is currently paid."
"This solution should include Power BI so that we don't have to use any third-party tools."
"They should have more training materials available that are specific to .NET. We spend a lot of money training our engineers."
"In the realm of Microsoft .NET Framework, particularly in the C# language, there have been significant developments that I find highly commendable. I am genuinely fascinated by the continuous evolution of the language, and staying abreast of the latest features in Azure is both challenging and enjoyable. Working with C# in Azure is particularly fantastic. I appreciate in .NET, as compared to Java, is the enforcement of types, providing a better experience in terms of technicalities. Additionally, the introduction of Roslyn in the past few years has brought about the concept of late .NET, which I find interesting and powerful. This allows for the transformation of symbolic code just before execution, eliminating the runtime decision-making process and enhancing efficiency. However, late .NET does come with a drawback – a delay in the last-minute computation when starting an executable. While some may find this less appealing in terms of instant responsiveness, especially in serverless cloud environments, the efficiency gained from executing strictly binary code is valuable. Despite potential drawbacks like the time required for activation, I view .NET favorably for its technical advancements and efficiency, especially in scenarios such as serverless cloud computing. It's essential to recognize the intricacies of how .NET processes code and the efficiency it brings, which some may overlook."
"The solution is difficult to learn if someone is learning it for the first time."
"I would recommend Magic rather than .NET. It takes longer to develop something on .NET."
"Initial setup is somewhat complex and requires some training."
"Microsoft's strategy is not scalable, especially with the Visual Studio environment."
 

Pricing and Cost Advice

"It is very expensive."
"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."
"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."
"I don't remember the price, but there are no additional costs."
"We pay around $200,000 annually."
"IBM WAS base is part of the deal when you purchase IBM FileNet P8 Content Engine."
"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 product’s pricing is a bit 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."
"Microsoft .NET Framework is very cost-effective for corporate users."
"We have an annual license, and we pay extra for extended support."
"The pricing could be cheaper."
"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."
"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."
"Do your homework. Consider the partnership program."
