The text discusses the integration of AWS Lambda with Kafka topics to create scalable, event-driven architectures suitable for various industries, highlighting two primary integration patterns: using AWS Lambda as a sink connector and configuring Kafka as an event source. The Lambda Sink Connector allows synchronous or asynchronous invocation of functions, offering flexibility in workload management, while the event source mapping pattern automatically invokes Lambda functions based on message flow, supporting auto-scaling and load monitoring. The text provides detailed insights into each pattern's operational features, such as message processing, error handling with dead-letter queues, and parallel task executions. It also presents real-world use cases in healthcare and email marketing, illustrating the practical applications of these integrations. Additionally, the text mentions Confluent Cloud's support for multiple Lambda functions and cost-effective scaling, with an example from BT Group's use of Confluent for real-time data streaming in telecom.
