Apache Camel is an open-source integration framework that allows developers to create complex integration solutions with ease. It provides a set of pre-built components that can be easily integrated into existing applications, making it easier to connect and exchange data between different systems. The framework supports a wide range of protocols, data formats, and technologies such as REST, SOAP, JMS, CSV, XML, and JSON. It is widely used in enterprise applications to implement ETL (extract, transform, load), EAI (enterprise application integration), and SOA (service-oriented architecture) solutions.
