Offers large-sized business information processing with a time-saving setup and impressive stability
I primarily use two previews of the product for Dev and two for QA as part of the production process. Whatever tools our company is using, the cost of a license in IBM WebSphere Message Broker is about 80% of all these software or tools. The message routing capabilities satisfy workflow efficiency. The product supports message formats of XML, JSON, and SSID, which are around 24 KB to 50 KB in size. The solution supports communication protocols like STTP and TCP. Features like DataGraph need to be introduced in IBM WebSphere Message Broker. Some of the clients of our organization are using an outdated version of IBM WebSphere Message Broker for which the vendor doesn't provide direct support anymore. For the aforementioned version, our company professionals can solve the queries on their own without seeking support from IBM. During the installation of a prior version of IBM WebSphere Message Broker, sometimes I have to configure the failovers through the cluster, where issues arise, and I often seek help from the support team. The solution is being used by some medicine companies in our organization that receive sales orders from the EDR or JDE. I would not recommend the product to others as its becoming obsolete and they can rather choose a middleware solution from Amazon or Azure. But I would overall rate the product a nine out of ten.

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

"It is a scalable solution...The setup is easy."
"This is a very reliable and stable solution that is used for a very large number of transactions."
"Overall, in comparison to other solutions specific to the banking domain, this product is quite good."
"We are using three or four services in the backend for reformatting messages, and it is straightforward to use."
"Message Broker is valuable because most of the applications are using MQ. Even in my current engagement, the few applications which I audit to onboard the bank are using MQ."
"IBM WebSphere Message Broker is one of the best middleware solutions"
"The most valuable features are the product's straightforward development and deployment, and its nice graphical user interface."
"The documentation, performance, stability and scalability of the tool are valuable."
"The solution is not limited in storage, is customizable and simple to use."
"The solution is user-friendly and straightforward."
"Pre-programmed functions for .NET Framework are widely available."
"The web development and Microsoft Windows service development capabilities are among the most valuable features offered by the Microsoft .NET Framework. This language platform is highly user-friendly, with plenty of online examples and information available, as well as a robust development environment."
"The .NET framework is a mature platform that is very helpful and saves time during the software development process."
".NET Framework saves us cost and time, provides quality and accuracy, and improves our security."
"The .NET Framework is easier to use because it provides a wide range of libraries."
"Firstly, I appreciate the decision to use Microsoft .NET Framework. I find it to be an excellent language, with a history rooted in providing an alternative to Java, albeit with initial challenges. It is gaining popularity and may be voted the most desirable programming language. What I particularly like about .NET is its language efficiency. While C# is the primary language, the platform also supports others, catering to those inclined towards functional programming. Although I started with Shell, I'm still grasping the concept of functional programming. Despite initial reservations about object-oriented programming, I acknowledge its advantages. .NET is a safer option, and despite criticisms, it has evolved over the years. One notable aspect is .NET's transition to an open platform in recent years, distancing itself from being exclusive to Microsoft engineers. I appreciate the versatility of .NET, enabling code production for a wide range of platforms, presenting a strong competition to Java. It allows targeting practically any physical platform, showcasing its flexibility. These qualities contribute to my positive view of .NET, totaling thirteen aspects that I find appealing."
 

Cons

"The user interface is designed mainly for experts, much in the way a BPM or another integration tool is."
"There is some lag in the GUI. There have been some performance issues and maybe it's because of the application data."
"They are expensive and not worth the money we are spending on them."
"I find the installation configuration is quite difficult compared to other solutions."
"The user interface is designed mainly for experts, much in the way a BPM or another integration tool is."
"I know that Message Broker was a very tightly copied product with another IBM product, that is, IBM MQ. I would like to have a little bit more decoupling from the IBM MQ because it should not be a prerequisite for IBM WebSphere Message Broker usage."
"It is currently a weighty product."
"The product's features are not being upgraded or enhanced by the vendor"
"Microsoft has its own product called Blazor, but I don't think it's quite as powerful yet as React or Angular. That's an area for improvement."
"I would like to see more pre-built features in the MVC framework because as it is now, it's very open and you have to develop your own controls in order to use it."
"In the next release, I am looking for more advanced technologies such as socket communication and enhanced features like realtime chat with the clients."
"I would like to see a better response time from the technical support."
"Lacking in auto-scaling."
"Initial setup is somewhat complex and requires some training."
"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."
"Microsoft could improve .NET Framework by providing more resources to help users understand the solution."
 

Pricing and Cost Advice

"The price is very high and it's the main reason that we are searching for alternatives."
"This product is more expensive than competing products."
"IBM products are generally more stable and have more features, but also come at a greater cost."
"The licensing cost of IBM WebSphere Message Broker needs to be reduced"
"IBM software can be costly, but having a contract has helped manage and potentially lower costs over time."
"The solution is expensive."
"I feel with IBM, when you want certain functions or features, you have to continuously purchase add-ons. There are always additional fees."
"The solution is expensive."
"Microsoft .NET Framework is very cost-effective for corporate users."
"If you want to develop an enterprise-level application, you have to purchase the enterprise-level development license."
"The product and support for this solution are free for everyone."
"The Microsoft .NET Framework is free of charge, without licensing cost."
"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."
"Microsoft .NET Framework is licensed under the Windows License."
"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."
