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

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

"It's an awesome solution. Compared to everything else that's out there in the market right now, IBM MQ is hands down the best solution available and that's based on 40 years of IT experience."

"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."

"We needed this type of integration and WebShepere is the best tool for it."

"The thing about WebSphere, as opposed to other ones that I am aware of such as JBoss and Liberty, is that WebSphere has the most comprehensive scaffolding available to it."

"The most valuable feature of this solution is Portal Virtualization."

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

"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

"My advice is that C# is a very rich language with lots of advanced facilities, which makes it easier to develop by not being too complex."

"I like that ASP.NET is used for the framework and the core web services."

"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."

"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."

"I'd rate the solution as highly stable."

"Whenever someone needs a very good back-end system or a strong system, they should go with C# .NET technologies."

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

More Microsoft .NET Framework pros

Cons

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

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

"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."

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

"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."

"IBM WebSphere Application Server hasn't changed much. It's still a heavyweight for any company compared to what you get. Unless your code base is deeply linked with it, I don't think it's a great idea to go with this solution. The current trend is toward modularity and containerization, and given the product's requirements, containerization will be difficult. There is a memory requirement as well."

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

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

More IBM WebSphere Application Server cons

"The solution has difficulty integrating with other products. There are no such difficulties if you have the same platform, hardware, and operating system."

".NET Is still heavy or dependant on other Microsoft libraries and frameworks."

"The integration capability of the product with AI is an area with certain shortcomings, where improvements are required."

"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."

"We have issues with websites that are based on Angular, but the rest of the applications or websites are stable so far."

"There may be some topics regarding connectivity and management of certificates that require attention. We are currently facing some issues."

"The price of the Enterprise version is quite high and can be improved."

"If AI could be incorporated in Microsoft .NET Framework it would be helpful."

More Microsoft .NET Framework cons

Pricing and Cost Advice

"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."

"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."

"The solution is quite expensive."

"It is very expensive."

"We used to pay about $100,000-$120,000 US or somewhere around there. That was a bit cost-prohibitive for us to continue."

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

"The pricing is a little expensive."

More IBM WebSphere Application Server pricing and cost advice

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

"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."

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

"Do your homework. Consider the partnership program."

"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."

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

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