Efficient orchestration and security features improve business processes effortlessly
JBoss ESB should focus on startup and performance as EAP is heavier than lightweight Java frameworks, which impacts microservices and cloud environments. Improvements should include faster start times and reduced memory footprints. Better cold-start performance in containers should be emphasized. Cloud-native features must be enhanced since many enterprises are shifting to Kubernetes and OpenShift, making EAP more cloud-friendly. This could include providing smaller container images, native auto-scaling support, and improved integration with cloud configuration services. Enhancing the developer experience is crucial; while the current configuration is powerful, it can be complex for newcomers. As an experienced user, I navigate it easily, but newcomers struggle due to heavy reliance on XML configuration. Transitioning to a JSON-based configuration or YAML format would be beneficial, and simplifications in clustering setup for local testing would greatly assist users.

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.

Quotes from Members

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

Pros

"The solution is very easy to use. I can download the trial version and just give it a go."
"The solution improved the company by modernizing the way they offer services and improving the user experience."
"The product offers a community edition that is free of cost."
"Mule ESB has a user-friendly design, and everything is in one place. The API and architecture are popular right now. Also, MuleSoft has a large and supportive online community."
"This tool has exceptional API management and integration connectors in addition to multiple out of the box connectors."
"The most valuable features of Mule ESB are its ease of use, documentation, ease to adapt to newer security and vulnerabilities, and a lot of help available. Additionally, there is a lot of flexibility, many patches available, and they provide APIs. They are a market standard."
"Mule ESB is the heart of applications that require routing and improvement of messages such as electronic invoicing."
"Mule ESB is quite lightweight."
"Mule ESB helps a lot with our microservice architecture that we're trying to build, and it is still our go-to technology when it comes to that, so it's very promising for us."
 

Cons

"JBoss ESB should focus on startup and performance as EAP is heavier than lightweight Java frameworks, which impacts microservices and cloud environments."
"The EPA, from what I understand, lacks a lot of features and it doesn't really know how to interface with legacy systems or how to develop APIs for legacy systems."
"Its licensing or pricing model should be improved. If I compare it to other solutions, it is very expensive for small and medium businesses."
"I think there are some connectors that are not available that should be included."
"The Mule IDE (Integrated Development Environment) could be more stable."
"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."
"The solution isn't as stable as we'd like it to be. There are some ongoing issues and therefore Mule has to provide frequent patches. Mule's core IP should be more stable overall."
"In an upcoming release, I would like to see more additional concept for exception handling, batch processing, and increased integration with other application."
"Overall, in isolation, it's a costly solution."
"Limitation on external subscribers to listen to the messages on the bus."
 

Pricing and Cost Advice

Information not available
"Mule ESB is a costly solution. We pay approximately $80,000 annually for the system. The cost of the number of instances, annual subscription, and cloud hosting services are expensive."
"This product is expensive, but it does offer value for money."
"Plan your licensing model (cloud or on-premises or hybrid) that will allow seamless integration with new partners."
"You will not get any support from Mule ESB's team for the tool's community edition...You can get support with the licensed version of Mule ESB."
"The various features and components for this solution are no longer free."
"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."
"Mule ESB is an expensive solution."
