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 is very easy to use. I can download the trial version and just give it a go."
"The best feature for me was the easy connectivity and easy integration."
"Mule ESB is quite lightweight."
"Once it is started, we don't see any problems on a day to day basis."
"The most valuable features are the connectors, DataWeave, and the way it simplifies the application development and deployable files."
"The transformation and the data format are the features that I like the most."
"The solution doesn't require much code writing and we can develop APIs very easily."
"The features that I have found most valuable are that the product is updated regularly and Mule's framework."
"The connectivity the solution provides is excellent, as we often have too many systems that we need to integrate and this platform helps significantly with that."
 

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."
"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."
"From the product perspective, it was sometimes hard to manage the dependencies. When we had to add dependencies on a couple of different packages, it was sometimes confusing. It was hard to update them with Anypoint Studio, as well as with MuleSoft. There were challenges with that. So, that's one of the areas that could be improved."
"The payment system needs improvement."
"Mule ESB isn't as secure as IBM. Financial companies go with IBM for that reason."
"Support, and with respect to licensing cost. Many of the customers feel that the licensing cost is much."
"Community editions need more attention."
"Mule ESB isn't as secure as IBM. Financial companies go with IBM for that reason."
"From an improvement perspective, there should be fewer coding challenges for users in Mule ESB."
"The initial setup could be more straightforward."
 

Pricing and Cost Advice

Information not available
"The price of the Mule ESB commercial version is expensive. However, they have a free community version."
"The licensing is yearly, and there are additional fees for services."
"This product is expensive, but it does offer value for money."
"The various features and components for this solution are no longer free."
"The pricing must be improved."
"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."
"Plan your licensing model (cloud or on-premises or hybrid) that will allow seamless integration with new partners."
"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."
