Best Practices for Middleware and Integration Architecture Modernization with Apache Camel
This document discusses best practices for middleware and integration architecture modernization using Apache Camel. It provides an overview of Apache Camel, including what it is, how it works through routes, and the different Camel projects. It then covers trends in integration architecture like microservices, cloud native, and serverless. Key aspects of Camel K and Camel Quarkus are summarized. The document concludes with a brief discussion of the Camel Kafka Connector and pointers to additional resources.

- 60. What is ApacheKafka? ● Kafka is known as ○ a distributed streaming platform ○ or a pub/sub messaging broker ● It’s an ecosystem ○ Multiple components part of Apache Kafka ○ A lot of 3rd party integrations ○ One of them is Kafka Connect Streams API Producer API Consumer API 3rd party tools Mirror Maker Connect
- 61. What is KafkaConnect? ● It is a framework that helps you to integrate Kafka with other systems ○ A user can define source and sink connectors to stream data in/out of Kafka brokers ○ Connectors are plugable - you can use one of the many connectors available or write your own ● Distributed and scalable by default ● Automatic offset management ● Simple transformations ● Streaming / batch integration Kafka Connect: Source Connector Kafka Connect: Sink Connector External System External System
- 62. What is CamelKafka Connector? ● A Kafka Connector built on top of Apache Camel ● Started as an internal proof-of-concept ○ A sub-project of the Apache Camel ○ Donated by Red Hat to the ASF on December 2019 ● Reuses in a simple way most of the Camel components as Kafka sink and sources
