Apache Camel Expertise
Camel is an integration framework, allowing to implement message exchanges between applications. It is based on Java and gives the possibility to route messages from one source to another.
In an information system, many heterogeneous systems that do not understand each other may need to communicate, and it may be necessary to link these applications together.
The integration architecture often refers to ESB, or Enterprise Service Bus. These middlewares allow the communication of applications that have not been designed to work together. ESB are often powerful tools, but can be impractical to implement. Today, “lightweight ESB” are simple integration frameworks that do not require installation, and enable the implementation of Enterprise Integration Patterns (EIP).
Apache Camel is in charge of transforming, enriching, aggregating or routing messages between applications. The Apache Foundation offers a panel of very diverse connectors, allowing an interface with many protocols.
Apache Camel makes it easy to express how to route messages from a source to one or more destinations. It defines routing rules and mediation rules in various domain-specific languages, using XML Blueprint, Spring, or Scala DSL configuration files. Routing rules are smart, regardless of the editor (Java, Scala or XML). For Camel, there is no conversion to make to a pivot format. This high-level abstraction layer allows all types of systems to communicate, without having to manage exchange protocols.
Camel is not an ESB because it does not have a message bus. it is a basic integration framework, with many connectors ready to use. One of its riches lies in the fact that it is widely expandable (more than a hundred connectors available) and can be interfaced with many technologies. This amount of connectors often makes it possible to find several solutions for each problem.
Integration solutions carry large amounts of potentially sensitive data. Security must be at the heart of every process and system of integration. With Camel, there are four levels of security: EndPoint Security, Route Security, Payload Security or Configuration Security.
In addition, it can work directly in HTTP, ActiveMQ, JMS, JBI, SCA, MINA or CXF, and can easily integrate into any Java application. It supports bean binding and integration with popular frameworks such as Spring, or Blueprint.
Apache Camel is a solution to consider if you need to integrate your information system. The variety of protocols, its Domain Specific Language and testing opportunities make Camel a simple yet powerful development framework. It requires no installation and is an alternative to the implementation of heavy architectures (ESB …). As for the community gathered around the Open Source ecosystem and the Apache Foundation, it is active and well-known. The documentation is enriched from day to day, and the Java approach allows it to be easily integrated.
Camel and the EIP
EIPs are integration models that allow us to solve integration problems with stable and verified solutions. They form a formalization for the integration problems that originally appeared in the book by Bobby Woolf and Gregor Hohpe: “Enterprise Integration Patterns“.
For Camel, each route is an assembly of multiple EIPs. This allows easy writing and maintenance. Each EIP responds to a specific need, and allows the use of the best techniques to reach a solution.
We accompany your projects
We can assist you in the process of setting up communications between your different applications, the routing of your messages or patterns that can normalize the exchange of messages in an asynchronous system.
We are able to :
