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."
"I like that Mule ESB provides fast and good technical support."
"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."
"The best features of this solution are that everything we get into a single platform, whether it's integration, API, or data modeling; everything is available in one platform."
"The most valuable feature is that it's programmer-friendly, so it's very easy to develop APIs."
"We have experienced zero downtime since moving to this solution."
"We suggested that clients switch to Mule ESB due to the lower licensing cost, the availability of cloud connectors, the CloudHub platform supporting iPaaS, and a suite of 110+ connectors to use."
"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."
"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."
 

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."
"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."
"The documentation is not extensive and is limited to examples which are too basic."
"From my perspective, Mule ESB is lightweight, but it can be improved when it comes to the agility of the system."
"The price of Mule ESB could improve."
"Licensing cost could be improved in this regard. Overall, the product is a bit on the expensive side."
"The current version will not be supported for much longer."
"Limitation on external subscribers to listen to the messages on the bus."
"It would be beneficial if users could navigate the UI easily without extensive training or learning curves."
 

Pricing and Cost Advice

Information not available
"Plan your licensing model (cloud or on-premises or hybrid) that will allow seamless integration with new partners."
"This is expensive. In my next project, we had to go to other vendor."
"I think the price is very high. If you use TIBCO BW, the license is for the CPU usage, then the IPS, and support. I also think the license for the product is a one-time expense."
"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."
"The various features and components for this solution are no longer free."
"The solution is expensive."
"This product is expensive, but it does offer value for money."
"Mule ESB is an expensive solution."
