MANUEL VALDIVIA - PeerSpot reviewer
Senior Manager at a financial services firm with 1,001-5,000 employees
Routes messages efficiently across our services, but the features for scalability need improvement
One of the key benefits has been its ability to expose services and securely integrate applications within our architecture. It's been integral in maintaining a stable infrastructure despite its limitations with dynamic service creation and flexibility compared to newer technologies like Kubernetes. The main challenge has been scalability during peak usage times.
Muhammad Qasim - PeerSpot reviewer
Solutions Architect at Diyar United Company
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 are using three or four services in the backend for reformatting messages, and it is straightforward to use."
"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."
"This is a very reliable and stable solution that is used for a very large number of transactions."
"Setup is very easy; we had proper documentation for setup, so it didn't take much time, and setup takes a maximum of two or three hours and I can set up the complete application."
"The most valuable feature of IBM WebSphere Message Broker is the ability to facilitate communication with legacy systems, offering a multitude of great capabilities. For example, if there is a mainframe system in place with a web service serving as the front end. In that case, the solution enables efficient protocol transformations to convert all request payloads into a format that the legacy systems can accept, rendering the integration and transformation processes seamless and highly effective."
"The solution has good integration."
"I'd rate the solution as highly stable."
"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."
"It facilitated the streamlined scheduling process by amalgamating inputs from various sources, including location data and other systems."
"Initial setup is straightforward. All the components are readily available."
"For us, it is better to remain under the umbrella of Microsoft."
"As we are scaling quite nicely on Azure."
"The return on investment is good because maintenance will come down, it is very easy to troubleshoot data, everything now is better, and the ROI is even much more."
"It's easy to create and integrate things."
 

Cons

"As our business requirements evolve, we require more dynamic capabilities to adapt and scale our services accordingly."
"Stability and pricing are areas with shortcomings that need improvement."
"The solution can add container engines such as docker."
"Technical support is very slow and needs to be improved."
"They are expensive and not worth the money we are spending on them."
"There is some lag in the GUI. There have been some performance issues and maybe it's because of the application data."
"Today I probably wouldn't go for Message Broker because of the cost structure, support, and the whole ecosystem around IBM."
"The images and size of the containers are too big and I think that they should be more lightweight."
"The product's price is an area of concern, making it an area where improvements are required."
"If AI could be incorporated in Microsoft .NET Framework it would be helpful."
"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."
"I would want the product to be integrated with the different AI tools in the future since it is one of the areas where the product has certain shortcomings."
"It is of great concern to us that the solution is not very powerful on cross platform, at it impedes the ability to build and scale with it."
"The runtime environment for ASP.NET needs improvement to make it more universal."
"We have issues with websites that are based on Angular, but the rest of the applications or websites are stable so far."
"Scalability is a bit messy so we're forced to use different solutions for different clustering."
 

Pricing and Cost Advice

"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."
"This product is more expensive than competing products."
"The price is very high and it's the main reason that we are searching for alternatives."
"IBM products are generally more stable and have more features, but also come at a greater cost."
"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."
"There is a Community Edition that can be used free of charge, but the licensing cost for the Enterprise version is quite high."
"If you want to develop an enterprise-level application, you have to purchase the enterprise-level development license."
"The solution is a bit costly when compared to open source products or open gear licenses."
"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."
"The product’s pricing is a bit high."
"The product is not expensive."
"The pricing could be cheaper."
"The solution is free but you need to pay for a license for the hosting service."
