Microservices have transformed our integrations and now highlight room to improve AI-driven tooling
There are areas in Red Hat Fuse that have room for improvement. We were recently having a discussion with Red Hat team building agentic AI, which we call AI SDLC. Something that the team is actively working on, but I have not really seen any production-level version of it is MCP. For us to use Red Hat Fuse with AI models, we need MCP so that we can be very confident that it can deliver us a really solid outcome when developers are using it, whether it is any of the integration patterns or messaging bus patterns. I have not seen that yet. Even though Red Hat has an alternative to that, such as a plugin, it is not as advanced as some of the MCPs that we see around.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"OpenESB pushes the organization to clearly define service boundaries and interfaces. So it motives the business and the development teams to clearly define their business services and processes they want to implement. OpenESB supports fine and coarse-grain granularity for the services and supports top-down and bottom-up approaches for the services, processes definition, and composition."
"One of our clients is a signature company and developed on a classic Java enterprise application using OpenESB, and in one year they saved £20,000,000 on development and maintenance."
"The process-oriented solution allows you to define choreography and orchestration."
"The core is very stable."
"Millions of people were connecting every month on the system and there were no issues."
"One of the most valuable features is being able to implement business processes while keeping track of the design from BPMN to a BPEL Implementation."
"ESL Gaming used OpenESB for its scalability and processes 1 billion of messages daily with a large configuration deployed on a private cloud."
"The support training that comes with the product is amazing."
"With a premium, one can get support 24 hours."
"It's very lightweight. There's no need for any specialized tools in order to deploy any service for Red Hat Fuse."
"Overall, this is a very good solution."
"Red Hat Fuse's best features are that it's very easy to set up and maintain."
"Any time we contact Red Hat for help we had got a satisficing response."
"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

"Regarding its management, a web console being able to synchronize distributed instances would be great."
"Cloud deployment is weak and needs to be improved."
"The documentation needs to be better — maybe they could add more accurate tutorials."
"The documentation needs to be better."
"The documentation of the product must be improved. It could be tricky to find the right documentation on a topic since the documentation is spread in many places. I advise the new joiner to contact the community to get entry points and additional documentation. Tutorial and Video must be present to take up the product."
"The Studio is a good tool based on NetBeans, but some of its features have to be improved, liked local schemas management."
"The testing part, specifically when running it in the cloud, could be improved. It's a little bit complex, especially considering its cloud nature."
"Currently, the main point of concern for us is how flexible it is to cater to different requirements. It should be more flexible."
"The stability of the solution is an area with a shortcoming that needs to be improved."
"Developers for Red Hat Fuse are scarce all over the world and the community is not well-built."
"The documentation for Fuse can be improved because, while it is very detailed and extensive, it is not too intuitive for someone that has to deliver some kind of troubleshooting services. In particular, for installation, re-installation, or upgrades, I find that the documentation can be improved."
"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."
"As its learning curve is quite steep, developer dependency will always be there in the case of a Red Hat Fuse development. This should be improved for developers. There should be some built-in connectors so the grind of the developer can be reduced."
"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."
 

Pricing and Cost Advice

"The cost for the prediction instrument is high because it is charged per instances based on prediction, but the rest of the solution is free."
"There are two versions. The first is the community version, which is free and contains the last part of the feature, but if you want to get the Enterprise version, you'll have to pay €60,000 which covers support and two instances on production."
"The Community Edition is a full product you can use in production, it does not have limitations like other alternatives."
"We are paying around $24 million across five years."
"This is an expensive product. It costs a lot and although it's worth the money, the explanations that we need to give to our top executives are highly complicated."
"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."
"Red Hat Fuse saved us money. It is a lot easier to license for cloud deployments."
"We use the standard license, but you need the container platform in order to run it."
"We found other solutions were more costly."
"Red Hat Fuse is an expensive tool, though I cannot answer how much it costs as that's confidential."
"This is an open-source product that can be used free of charge."
