Application integration with Apache Camel
Elegantly integrate isolated applications with Apache Camel – Enterprise Integration Patterns, Spring Boot and Java DSL through to cloud-native routes with Camel K on Kubernetes.
In this 2-day workshop, participants will learn how to elegantly solve integration challenges of varying complexity using Apache Camel – from classic enterprise integration patterns to modern event-driven and cloud-native architectures. Hands-on exercises are embedded in the Spring Boot ecosystem, using Apache Kafka for messaging and exploring deployment of Camel in Kubernetes environments. A key focus is placed on Apache Camel K, the cloud-native Camel framework for serverless and containerized integrations on Kubernetes.

Content
Most companies run several software products from different vendors in their day-to-day business. These applications may have different purposes, data storage and operating methods. This usually leads to data silos where data is either duplicated between databases or available in one database but not in another. As a result, companies complain about data inconsistency, slow process turnaround times, lack of early detection of changes in the business environment (customer behaviour), etc.
As a solution approach, integration architectures are designed that integrate the originally isolated applications (e.g. ERP, CRM…) with each other, bridging content and technological gaps. Apache Camel is a lightweight and flexible open source framework for the integration of self-contained applications, which supports the development of integration architectures. Camel’s strengths include the availability of various DSLs (Domain Specific Language) for describing routes and support for numerous enterprise integration patterns. Camel is also characterised by the fact that it can be embedded in all relevant ecosystems, such as Spring Boot, Quarkus, various application servers and Kubernetes.
After a short introduction to the problems of self-contained application systems, the following topics will be addressed:
- Requirements for an integration architecture and possible solutions (point-to-point, hub-and-spoke, enterprise service bus, etc.).
- Basic concept and architecture of Apache Camel
- Overview: Runtime environments for Apache Camel (standalone, embedded in various containers or in the Spring Boot Ecosystem)
- Camel DSL (Domain Specific Language) with focus on Java
- Selected Camel components
- Selected Camel data formats
- Enterprise Integration Patterns and their support by Camel
- Error handling and monitoring with Camel
- Apache Camel in the Kubernetes environment (containerization, configuration, logging, scaling)
- Introduction to Apache Camel K:
- Architecture and differences to classic Camel
- Development and deployment of Camel K integrations (YAML, Java DSL, Kamelets)
- Combining Apache Kafka and Camel K for event-driven architectures
- Use of operator, traits and integration with cloud-native services
- Hands-on labs with Camel K in a Kubernetes cluster
We focus on a specific set of topics to look at and understand in detail

More about Apache Camel
Apache Camel is a lightweight, open-source integration framework based on the proven Enterprise Integration Patterns (EIP) by Gregor Hohpe and Bobby Woolf. It allows developers to describe integration routes using various domain-specific languages (Java, XML, YAML) and supports over 300 components covering protocols, data systems, and cloud services. With Apache Camel K, a cloud-native framework for serverless and containerised integrations directly on Kubernetes is also available.Further resources:
History
Apache Camel was launched in 2007 as an open-source project under the Apache Software Foundation and is closely tied to the book "Enterprise Integration Patterns" by Gregor Hohpe and Bobby Woolf (2003), whose 65 patterns the framework fully implements. Originally conceived as a lightweight alternative to heavyweight Enterprise Service Buses, Camel has since grown into one of the most widely used integration frameworks in the Java ecosystem.
With the rise of Kubernetes and cloud-native architectures, Apache Camel K was developed – a specialised variant that runs Camel integrations directly as Kubernetes Custom Resources and supports serverless deployment models. Today, Camel is firmly established across ecosystems such as Spring Boot, Quarkus, and Red Hat Integration.
