AWS Serverless Microservices with Patterns and Best Practices - Developing SQS Event Source Mapping Polling Invocation o

The video tutorial covers the development of a microservice for processing orders using AWS services. It begins with an introduction to event source mapping and the use of DynamoDB for order storage. The tutorial then delves into the development of SQS invocation, iterating over records, and handling messages to extract checkout requests. The process of creating orders in DynamoDB is explained, followed by finalizing the development and preparing for end-to-end testing of the serverless e-commerce application.
