Room For Improvement

IBM Integration Bus needs enhancements in functionality, support, cost, interface, architecture, and integration with cloud and DevOps.

Red Hat Fuse requires UI updates, better documentation, pricing flexibility, improved configuration, built-in connectors, and enhanced stability and monitoring.
They are improving one of the nodes such as the HTTP request node, implementing the indirect retry mechanism itself, and we are getting new features.
Associate Consultant at MindCraft Software Pvt. Ltd.
Points for improvement in Mule ESB definitely include enhancing the analytics capabilities because currently, they rely on external logging tools such as Splunk or ELK, which is lagging behind compared to other tools such as Workato that offer more analytical features.

Setup Cost

IBM Integration Bus is costly for small firms but reasonable for large enterprises, with concerns over licensing complexity.
Mule ESB's cost and flexible licensing appeal to enterprises, yet high fees lead smaller businesses to explore alternatives.
Red Hat Fuse offers competitive pricing with potential discounts, valued for enterprise support but costs may rise with consulting.
Regarding the pricing setup cost and licensing for IBM Integration Bus, I believe it is expensive.
Associate Consultant at MindCraft Software Pvt. Ltd.
We are in the third renewal since we migrated to Red Hat Fuse. Cost always goes up, it does not go down.
Chapter Area Lead/GM Group Architecture & IT at Spark New Zealand

Efficient data transformation and seamless integration drive successful deployments
As for improvements in IBM Integration Bus, we are getting another feature of the retry mechanism now. Version 8.13 was upgraded, and we started using the retry mechanism itself, and we are using nodes in the development level. They are improving one of the nodes such as the HTTP request node, implementing the indirect retry mechanism itself, and we are getting new features.
Srinivas-Kanduri - PeerSpot reviewer
Enterprise integrator at a tech vendor with 10,001+ employees
Integration architecture has enabled reliable multi-channel messaging and secure API management but now needs better analytics and simpler development
In my opinion, the real-time analytics part of Mule ESB is not up to the mark for the decision-making process. While there are some analytics features, they lack the standards needed for enterprise use. Compared to other analytics tools such as Power BI, MuleSoft falls short.Points for improvement in Mule ESB definitely include enhancing the analytics capabilities because currently, they rely on external logging tools such as Splunk or ELK, which is lagging behind compared to other tools such as Workato that offer more analytical features. Additionally, issues arise with AI-based use cases due to dependencies on Salesforce tools such as agent force, making development more complicated when it should be more independent. Developing AI-based agents without being tied to Salesforce applications could also enhance functionality.
Nilay Rathod - PeerSpot reviewer

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.
