This course is about enterprise integration patterns proposed by Apache Camel.

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

This pattern allows the externalizing and runtime behavior variability without requiring application redeployment.The Runtime Reconfiguration pattern is also known as the **Runtime Variability pattern**.

## Context and problem

A business service can be composed of multiple short processing flows connected together. It is possible to change the internal behavior of the service without changing its public interface by rearranging the internal processing steps. In the Reusable Route pattern, we have seen how to reuse Camel routes by linking them together at deployment time. From an object-oriented point of view, that approach is similar to the structural Bridge design pattern where an abstraction (API in the integration world) and its implementation (the actual processing flow in the integration world) can vary independently.
