Mule is an an Enterprise Service Bus (ESB) equipped with a set of principles and rules for connecting applications together over a bus-like infrastructure. ESB products enable users to build this architecture, but they differ in their methodology and the capabilities they provide. ESBs promote organizational agility by implementing a simple, well defined, “pluggable” system that scales well.
ESB helps to increase organizational agility, reduce the time to market for new initiatives or increase the number of applications being produced. An ESB architecture provides a simple, well defined, “pluggable” system that scales effectively thereby leverages existing systems and expose them to new applications using its communication and transformation capabilities
Mule as an ESB is the most lightweight integration platform available. The Mule runtime has modularization, fast deployment, and a configuration model that makes it simple to re-order, add, or change functionality.
It helps in exchanging data across numerous and varying formats and transport protocols
Mule as an ESB uses common tools that all Java developers are familiar with, like Maven, Eclipse, JUnit and Spring. It helps new developers get up to speed quickly with a graphical development environment.
Mule as an ESB does not force XML messages on its users. While XML is commonly used, there are many scenarios where you will want to use JSON, flat files, Cobol Copybooks, binary and file attachments, streams, and Java objects. Mule streaming allows developers to process large messages efficiently.
To lower IT application costs as well as reduce staff hours.
There are numerous advantages to deploying applications in the cloud, and there are advantages to deploying on-premise, or a hybrid of the two.
Mule can expose and host reusable services using the ESB as a lightweight service container
it can shield services from message formats and protocols, separate business logic from messaging, and enable location-independent service calls
Mule as an ESB routes, filters, aggregates, and re-sequences messages based on content and rules
