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

"Security: It is compatible with the latest Java 8 security features, supports FIPS 140-2 and NIST SP 800-53 with strong ciphers and cryptography keys, and supports TLS 1.2 completely. Also, configuring client and server certificates is relatively easy."

"The solution is very stable and robust."

"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."

"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."

"High availability, alert management, and deployments are the most valuable features for us. We have the ND version so we can do deployments."

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

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

"IBM WAS is extremely scalable. It is easy to add additional servers and to divide the load over servers in all kinds of ways."

More IBM WebSphere Application Server pros

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

"The solution is easy to use if the user is a developer or some technical person."

"Microsoft .NET Framework’s most valuable features are web application development, RESTful services development, security, performance, and less memory footprint."

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

"The product has a good interface and easy-to-use programming language."

"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."

"This is a solution that I recommend, but the best versions to have are 3.5 and 4."

"The Windows Communication Foundation is the biggest advantage we get from the .NET Framework."

More Microsoft .NET Framework pros

Cons

"The business logic side of it is sort of missing in the sense that if I want to track and measure velocity, it is not really available. You have to buy another application and embark on a separate implementation. Instead of having different licensing, IBM DataPower should be integrated with WebSphere. It will allow us to build the business layer and rules a lot more efficiently, rather than developing rules within the application. It would be good if we can set up the business layer through parametrization rather than development. IBM DataPower has the business rule and the controls, and if it can be integrated, it would be fantastic. It will help the application in working better in terms of security features and business logic. If you're going to use it for open banking, you will be able to monitor velocity on the total pricing."

"The solution could improve the integration."

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

"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."

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

"The solution consumes hardware."

"IBM needs to pay attention to market changes more quickly. We now have Java 9 and very soon Java EE8. We do not want to wait for two or three years after their release until they are supported by the new version."

"I would note that the response time is something IBM's support team needs to improve."

More IBM WebSphere Application Server cons

"Improvements are needed in .NET development, particularly in a backend scenario."

"The main obstacle in this technology is that it is currently paid."

"The product's price is an area of concern, making it an area where improvements are required."

"The pricing is a bit expensive."

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

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

"One thing that could be improved is the tooling and IDE for .NET in non-Windows environments like Mac."

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

More Microsoft .NET Framework cons

Pricing and Cost Advice

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

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

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

"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 pricing is a little expensive."

"We pay around $200,000 annually."

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

"It is very expensive."

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 licensed under the Windows License."

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

"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."

"It's an expensive solution"

"The product is not expensive."

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

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