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 improves a system's stability and resilience by guarding integration points against cascading failures and slow responses from external systems.

## Context and problem

We have seen how the Retry pattern can help us overcome transient failures, such as slow network connections or temporarily overloaded services, by retrying the same operation. Sometimes, a failure may require human interaction to rectify it, or its recovery can take forever. There is no benefit in retrying the same operation repeatedly and putting additional load on an already struggling system in similar situations. Instead, the application should detect that the remote service is unavailable and deal with it gracefully until the service is back and healthy again.
