Room For Improvement

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.
