AWS Serverless Microservices with Patterns and Best Practices - AWS Lambda Invocation Types - Introduction to the Course

The video tutorial covers AWS Lambda invocation types, including synchronous, asynchronous, and event source mapping with polling. It explains how each type functions, their use cases, and the services that can trigger them. Synchronous invocation involves immediate execution and response, while asynchronous invocation processes events without waiting for a response. Event source mapping uses polling to retrieve records from streams or queues. The tutorial also highlights the importance of setting the correct invocation type and handling errors effectively.
