AWS Serverless Microservices with Patterns and Best Practices - Developing deleteProduct CRUD Methods for Product Lambda

This video tutorial covers the implementation of a delete operation in a Lambda microservice using AWS DynamoDB and JavaScript. It begins with an overview of the necessary AWS tools and progresses to modifying the switch statement to handle delete requests. The tutorial then details the implementation of the delete product method, including error handling and parameter setup. Finally, it discusses the integration of the delete method with API Gateway and Lambda functions, ensuring proper handling of HTTP delete requests.

What is the primary purpose of the cloud method discussed in the video?

• To manage microservices using AWS Lambda and DynamoDB

• To enhance the user interface of the application

• To increase the storage capacity of the database

• To improve the security of the application

Which HTTP method is added to the switch statement in the video?

• GET

• PUT

• POST

• DELETE

What is the key focus when implementing the delete product method?

• Creating new database entries

• Deleting a product using its ID

• Handling incoming HTTP requests

• Logging user activities

What is a crucial step before sending a delete item command to DynamoDB?

• Creating a new database

• Defining parameters with table name and key

• Setting up a new API Gateway

• Logging all database entries

What is the role of the try-catch block in the delete product function?

• To create new entries in the database

• To log successful deletions

• To handle errors during DynamoDB interactions

• To enhance the speed of the function

How is the product ID obtained for the delete operation?

• From a static configuration file

• From the API Gateway event parameters

• From a user input form

• From a hardcoded value in the code

What is the expected outcome after sending a delete item command?

• A new item is created in the database

• The item is updated with new values

• The specified item is removed from the database

• The database is backed up
