Apache Camel is an Open Source Integration framework based on known [[https://camel.apache.org/components/4.0.x/eips/enterprise-integration-patterns.html|Enterprise Integration Patterns (EIP)]].

EIPs implemented by Camel are described in a well known [[https://www.enterpriseintegrationpatterns.com/|Enterprise Integration Patterns book]].


  * Camel empowers you to define routing and mediation rules in a DSL (e.g. Java, XML, YAML etc)

    * as well as pluggable Components and DataFormat options
  * Camel has 
    * support for BeanBinding
    * integration with some popular frameworks (like Spring)
    * support for unit testing of routes

  * Apache Kameleon -> https://kameleon.dev/#/standalone
    * A project generator for Apache Camel. It generates maven-based Java project with preconfigured Apache Camel runtime and selected components/extensions.
      * The simplest way to generate a new Camel project.
    * On Github: https://github.com/apache/camel-kameleon

  * Apache Karavan -> https://github.com/apache/camel-karavan
    * UI ("designer") to handle Camel routes etc.
    * Karavan can run as
      * web application
      * VS Code extension
      * Eclipse Che plugin
    * Runs generated code with 
      * JBang ("standard" way)
      * after the export the code can run with
        * Quarkus
        * Spring Boot
    * If Karavan is installed in Kubernetes
      * as web application
        * -> export to git
          * -> Tekton pipelines
