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 Some of the clients of our organization are using an outdated version of IBM WebSphere Message Broker for which the vendor doesn't provide direct support anymore.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 API-led architecture and provides a unique, user-friendly, and scalable architecture for hosting APIs
There's room for improvement in multi-file transfer functionality. It's not convenient when using MuleSoft, and it should have better capability for handling large amounts of data. For example, applications like GoAnywhere can handle huge chunks of data, so the tool should also have something to facilitate that aspect of integration.

Offers a single console for all applications and supports Camel routing
Containerization is one key area where the product can improve, but it probably has already improved in JBOS integration. On a few occasions, our company's production team faced an issue with Red Hat Fuse; the screen displayed that the containers had gone down while, in reality, they were running in the background. The user interface and the back-end code were not in sync in the aforementioned situation, which our organization frequently faced while using Red Hat Fuse. But at our company, we were using an older version of Red Hat Fuse in which we faced the issues. From the JBOS end, the product was very frequently changed from Red Hat, and it was difficult for our clients to keep investing money in every upgrade. Six or seven years back, Red Hat Fuse was one of the best solutions.

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."
"The transactions and message queuing are the most valuable features of the solution."
"It's reliable for our day-to-day operations, ensuring fast and secure data integration across different systems."
"The solution has good integration."
"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."
"We only use the basic features, but the most valuable one for us is the Publish-subscribe pattern."
"The documentation, performance, stability and scalability of the tool are valuable."
"IBM WebSphere Message Broker is one of the best middleware solutions"
"The most valuable feature is that it's programmer-friendly, so it's very easy to develop APIs."
"The transformation and the data format are the features that I like the most."
"What Mule provides out-of-box is a sufficient product."
"The setup is straightforward."
"The most valuable feature of Mule ESB is data transformation, i.e. our interacting with different systems and orchestrating for our business needs."
"Mule ESB is a very easy-to-use and user-friendly solution."
"Once it is started, we don't see any problems on a day to day basis."
"Scalability and load balancing."
"What I like about Red Hat Fuse is that it's a well-established integration software. I find all aspects of the tool positive."
"Red Hat Fuse's best features are that it's very easy to set up and maintain."
"One of the features I found most valuable in Red Hat Fuse is that it has a lot of containers so you won't have to worry about load balancing. In the past, there was a cut-off, but nowadays, Red Hat Fuse is moving off of that, so my team is utilizing it the most for load balancing, particularly running goal applications and three to five containers. There's automatic load balancing so you won't have to worry too much. I also found that component-wise, you don't have to do much coding in Red Hat Fuse because everything is configurable, for example, XML-based coding. Coding isn't that difficult. Performance-wise, I also found the solution to be quite good and its processing is quite fast. My team is processing a huge amount of data with the help of Red Hat Fuse."
"The process workflow, where we can orchestrate and design the application by defining different routes, is really useful."
"The solution is stable. We have gone for months or years without any issue. There are no memory restarts, so from my point of view, it's very stable."
"It's very lightweight. There's no need for any specialized tools in order to deploy any service for Red Hat Fuse."
"More than a feature, I would say that the reliability of the platform is the most valuable aspect."
"This solution's adaptability to our use case has helped us integrate our systems seamlessly."
 

Cons

"It is currently a weighty product."
"As our business requirements evolve, we require more dynamic capabilities to adapt and scale our services accordingly."
"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."
"The installation configuration is quite difficult."
"The solution can add container engines such as docker."
"The images and size of the containers are too big and I think that they should be more lightweight."
"Technical support is very slow and needs to be improved."
"The user interface is designed mainly for experts, much in the way a BPM or another integration tool is."
"Community editions need more attention."
"There's room for improvement in multi-file transfer functionality. It's not convenient when using MuleSoft, and it should have better capability for handling large amounts of data. For example, applications like GoAnywhere can handle huge chunks of data, so the tool should also have something to facilitate that aspect of integration."
"I would like to see support for BPM in the next release of this solution."
"The initial setup could be more straightforward."
"Documentation is cryptic, product releases are far too frequent, and upgrades become troublesome."
"There are some features on the commercial version of the solution that would be great if they were on the community version. Additionally, if they added more authorization features it would be helpful."
"The initial setup is not easy."
"I cannot say that installation with Kubernetes needs to be improved to be less tricky, but more information is needed from MuleSoft. They do not help much with Kubernetes, so we should have a person who is well-versed in Kubernetes to handle this."
"What could be improved in Red Hat Fuse is the deployment process because it's still very heavy. It's containerized, but now with Spring Boot and other microservices-related containers, deployment is still very heavy. Red Hat Fuse still has room for improvement in terms of becoming more containerized and more oriented."
"Our clients would like to see the user interface improved so that it is more user-friendly."
"In the next release, I'd like more stability and more security overall."
"My company doesn't have any experience with other messaging tools, so it's difficult to mention what areas could be improved in Red Hat Fuse, but it could be pricing because I find it expensive."
"Containerization is one key area where the product can improve"
"The main issue with Red Hat Fuse is the outdated and scattered documentation."
"Red Hat Fuse doesn't have a lot of administrative control like other applications."
"What needs to be improved in Red Hat Fuse is on the development side because when you use it for development purposes, it lacks a user interface compared to what MuleSoft has, so it's a bit difficult for users."
 

Pricing and Cost Advice

"IBM software can be costly, but having a contract has helped manage and potentially lower costs over time."
"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"
"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."
"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."
"This product is cheaper than some offered by other vendors, although there is a problem because you have to pay for some third-party adapters."
"Most of the challenges that I had with this solution were for smaller customers. There is not a good licensing model or pricing model. It is more expensive than other solutions, and that's the downside of MuleSoft. I had to be creative to be able to sell it to the business, but we did. This is something they have to work on because for large companies, it's affordable, but for small and medium businesses, it's very hard to sell."
"Plan your licensing model (cloud or on-premises or hybrid) that will allow seamless integration with new partners."
"Mule ESB is an expensive solution."
"The licensing is yearly, and there are additional fees for services."
"The price of the Mule ESB commercial version is expensive. However, they have a free community version."
"The various features and components for this solution are no longer free."
"The solution is expensive."
"The most important feature of Fuse is the cost. It is open source and a cheap option for an ESB. So, most of the clients in the Middle East and Asian countries prefer this ESB. Other ESBs, like MuleSoft and IBM API Connect, are pretty expensive. Because it is open source, Red Hat Fuse is the cheapest solution, providing almost every integration capability."
"We found other solutions were more costly."
"This is an open-source product that can be used free of charge."
"After doing some Googling and comparisons, the main standouts were MuleSoft and Red Hat Fuse. One of the big factors in our decision to go with Fuse was the licensing cost. It was cheaper to go with Fuse."
"Red Hat Fuse is an expensive tool, though I cannot answer how much it costs as that's confidential."
"Our license for Red Hat Fuse is around $27,000 per year, which is very expensive."
"You need to pay for the license. It's not free."
"We are paying around $24 million across five years."
