The video tutorial covers the use of AWS SDK for JavaScript to interact with DynamoDB in a microservices environment. It explains setting up the DynamoDB client, implementing a method to retrieve a product using the get item command, and the importance of logging and error handling. The tutorial emphasizes using the latest Ecmascript version for imports and provides insights into AWS documentation for better understanding.
