The most valuable feature of Mule ESB is data transformation, i.e. our interacting with different systems and orchestrating for our business needs.
Mule ESB is scalable with load balancing and connectivity options, yet documentation is cryptic and upgrades troublesome. DataWeave transforms data, and Anypoint Enterprise Security offers security and API management. Salesforce integration adds value, but dependency management is challenging. Despite user-friendliness, architecture knowledge is necessary. Stability requires patches, and pricing is uncompetitive, affecting adoption compared to IBM. Extensive community support is offset by security concerns in financial sectors.
