Mule ESB is very much essential in developing and implementing various modes of interactions and flows between applications and platforms made in a service-oriented architecture. Mule is a Java-based enterprise service bus (ESB). Mule ESB allows developers to connect applications together quickly and enables communication and data interchange. It also enables easy integration of existing and legacy systems, regardless of the different technologies being used by the application, including JMS, Web Services, JMS, HTTP, JDBC and more.
An ESB allows different applications to communicate with each other through a transit system that carries data between these applications either within the network or across the Internet.
Mule ESB has the following capabilities:
Service mediation — Mule ESB safeguards services from message formats and protocols, enable location-independent service calls and separate business logic from messaging
Service creation and hosting – ESB serves as a lightweight service container in which it exposes and hosts reusable services.
Data transformation – Mule allows data exchanges regardless of the format and transport protocol.
Message routing -Based on rules and content Mule allows messages to be rerouted, filtered, aggregated or re-sequenced.
Why use an ESB?
Most of the companies implement an ESB as the backbone of their IT infrastructure is mainly to increase organizational agility by reducing time to market for new initiatives. An ESB architecture eases this by providing a simple, well defined, pluggable system that scales really well. Additionally, by using its communication and transformation capabilities an ESB provides a way to leverage your existing systems and expose them to new applications.
