Executive SummaryUpdated on Mar 5, 2025

IBM WebSphere Application Server and Microsoft .NET Framework are key players in the application development and deployment arena. Microsoft .NET Framework has a slight advantage in terms of features, highlighting superior functionality based on user feedback. Conversely, IBM WebSphere is praised for its robust support and cost-effectiveness for enterprises.

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.

Improved security and streamlined cloud deployments have reduced maintenance and simplified troubleshooting

The Visual Studio ID that we are using requires more RAM and IP. Sometimes it goes high on this phone exchange, and it crashes sometimes. We have to review this with Microsoft itself. That is something we do not understand. The breakage goes up, and I think it was the process that decreased, but still partitions are there somehow in Cloudera Selami. We do not even understand what the issue is. I think six more RAM would help.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"This solution is easy to use with a GUI that is intuitive and very helpful."

"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."

"WebSphere Application Server is very stable."

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

"The product offers good performance."

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

"If you want a product you can have confidence in, and a product with good availability, then IBM WebSphere Application Server is for you."

More IBM WebSphere Application Server pros

"Ease of use, the richness of the libraries and basically very good development tools."

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

"The .NET framework is a mature platform that is very helpful and saves time during the software development process."

"In-built refactoring and .Net profilers are the most valuable features of the solution."

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

"Using this framework has enabled us to create services out of things we used to do manually, making our lives easier and increasing productivity as well."

"Microsoft .NET Framework continually innovates, particularly in Visual Studio, which focuses on improving languages, debugging, and .NET functionality."

"Microsoft is better in backward compatibility compared to others."

More Microsoft .NET Framework pros

Cons

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

"The solution consumes hardware."

"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."

"They should make the solution more lightweight and not bundle everything into a single product."

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

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

"As the license cost is quite expensive, I'm rating it two out of five."

"The solution could improve the integration."

More IBM WebSphere Application Server cons

"If Microsoft would provide a monthly subscription at a cost that a developer can afford then it would be really helpful."

"The pricing is a bit expensive."

"Better integration with other tools to make the operation faster would be an improvement."

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

"The cloud features must be improved."

"The solution could improve by optimizing the memory for better performance."

"The initial setup is complex."

"It would be nice if the framework were able to work with additional environments and systems like Linux."

More Microsoft .NET Framework cons

Pricing and Cost Advice

"It's 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."

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

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

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

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

"The pricing is a little expensive."

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

More IBM WebSphere Application Server pricing and cost advice

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

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

"Do your homework. Consider the partnership program."

"The product is not expensive."

"The product’s pricing is a bit high."

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

"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."

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