The Camel Enterprise Integration Patterns (EIP) provide the interfaces to communicate with large component-based distributed systems. When designing the best integration solution for message-oriented applications, these patterns help save time and effort.

In this course, you'll learn about all four foundational patterns. You'll be introduced to Error Handling patterns, Deployment patterns, and Configuration patterns. Each pattern is discussed in detail to be used in distinct settings. You'll also gain a deep understanding of how each pattern works under different circumstances, and implement them appropriately when necessary using real-world examples to illustrate the design specifics. Camel EIPs offer advantages over traditional frameworks such as REST or SOAP regarding integration problems within an organization.

By the end of this course, you'll have hands-on practice with valuable interfaces and the simplification processes for integrating applications across an organization's services.

Using Apache Camel with Enterprise Integration Patterns

## Intent

It is used to parameterize the configuration information of an application and externalize it from the deployment archive. The External Configuration pattern is also known as the **External Configuration Store**.

## Context and problem

A very simplified view of an integration application is that it moves data from source to target. While doing so, the application splits messages, aggregates them, does data transformation, handles errors, and may perform a number of retries. The endpoint details differ while developing and deploying this application from development to production environments, and other configuration options and tuning details need to vary. During the application’s lifetime, the team gets more insight into the application’s behavior, and further tuning is needed. Configuring the same binaries to run in different environments, and tuning them during production maintenance windows without changing the actual binaries, requires externalizing multiple configuration options, even those that might not seem likely to change.
