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.

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.

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."
"With Mule as its core runtime engine, Anypoint Platform is built with open technologies to promote reusability, modularity and collaboration, increasing developer productivity and project speed."
"It is an ESB that can deploy seamlessly on-premises and in the cloud with strong API management and governance and has a strong integration with open source products like JBPM and Drools if these features are part of your requirements."
"Mule ESB is quite lightweight."
"We can use Java expressions anywhere in the flow."
"The solution doesn't require much code writing and we can develop APIs very easily."
"One of the key features I find unique and most useful in Mule ESB is the loosely coupled architecture, allowing for multi-delivery where the same data can be sent to multiple systems."
"The solution improved the company by modernizing the way they offer services and improving the user experience."
"The solution offers multiple deployment options."
 

Cons

"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."
"JBoss ESB should focus on startup and performance as EAP is heavier than lightweight Java frameworks, which impacts microservices and cloud environments."
"Documentation is cryptic, product releases are far too frequent, and upgrades become troublesome."
"This solution could be improved by making it more flexible, and more user-friendly."
"I think using Anypoint Studio at the beginning can be seen as not straightforward, especially when dealing with the visual editor."
"It is getting expensive and I recommend clients to use Camel ESB if enterprise support is not required."
"We did have scalability issues. It demanded more RAM at times, when there were a larger number of requests while listening over FTP."
"The Mule IDE (Integrated Development Environment) could be more stable."
"The initial setup is not easy."
"Community editions need more attention."
 

Pricing and Cost Advice

Information not available
"The pricing must be improved."
"The licensing is yearly, and there are additional fees for services."
"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."
"Regarding licensing and pricing, I find it somewhat flexible. They are more flexible with larger customers compared to small and medium ones, as their licensing model depends on ports and other factors. Large customers benefit from more flexibility in implementation and renewal compared to smaller ones."
"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."
"This product is expensive, but it does offer value for money."
"This is expensive. In my next project, we had to go to other vendor."
"The various features and components for this solution are no longer free."
