Featured Reviews

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

"The most valuable features are the product's straightforward development and deployment, and its nice graphical user interface."
"Integration and mapping are easy, which is a major advantage."
"It's reliable for our day-to-day operations, ensuring fast and secure data integration across different systems."
"Straightforward development and deployment."
"The transactions and message queuing are the most valuable features of the solution."
"We only use the basic features, but the most valuable one for us is the Publish-subscribe pattern."
"Before the cloud, it was very easy for us to build and it was quick to integrate."
"IBM WebSphere Message Broker is one of the best middleware solutions"
"The Windows Communication Foundation is the biggest advantage we get from the .NET Framework."
"The most valuable feature is the financial accounting."
"A great solution for creating program solutions in a framework for Microsoft Windows quickly and easily."
"The most valuable feature is customization."
"It facilitated the streamlined scheduling process by amalgamating inputs from various sources, including location data and other systems."
"The addition of generics to handle common functionality across types, and the more recent upgrade of the dataset to the Entity Framework, has cut development time drastically, while increasing quality and confidence between builds."
"This is a solution that I recommend, but the best versions to have are 3.5 and 4."
"The product is evolving, based on the day-to-day needs of our customers and we are making sure to include maximum functionality to support their businesses."
 

Cons

"They are expensive and not worth the money we are spending on them."
"My biggest complaint about this product is the price."
"The solution can add container engines such as docker."
"I find the installation configuration is quite difficult compared to other solutions."
"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."
"Today I probably wouldn't go for Message Broker because of the cost structure, support, and the whole ecosystem around IBM."
"Technical support is good but they could have a better response time."
"The images and size of the containers are too big and I think that they should be more lightweight."
"They should try to improve their Blazor WebAssembly."
"The product’s reliability needs improvement."
"The integration with DevOps tools, such as Azure DevOps, Jira, and GitLab, would be a valuable addition."
"In my opinion, this solution can be improved by providing out-of-the-box support for different types of libraries."
"The runtime environment for ASP.NET needs improvement to make it more universal."
"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."
"One thing that could be improved is the tooling and IDE for .NET in non-Windows environments like Mac."
"The learning curve could be improved."
 

Pricing and Cost Advice

"The licensing cost of IBM WebSphere Message Broker needs to be reduced"
"IBM products are generally more stable and have more features, but also come at a greater cost."
"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."
"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."
"IBM software can be costly, but having a contract has helped manage and potentially lower costs over time."
"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."
"The product’s pricing is a bit high."
"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."
"If you want to develop an enterprise-level application, you have to purchase the enterprise-level development license."
"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."
"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 product and support for this solution are free for everyone."
"The Microsoft .NET Framework is free of charge, without licensing cost."
