The video tutorial explains the integration of AWS Lambda with Amazon SQS, focusing on how Lambda functions can process messages from SQS queues. It covers different invocation types, including event-driven and Lambda polling, and provides examples of event source mapping. The tutorial also discusses the structure of Amazon SQS message events and how Lambda functions handle these events, including message deletion after successful processing.

What is the primary role of Amazon SQS in the context of ordering Lambda microservices?

• To provide real-time analytics

• To manage user authentication

• To pull events from the ordering queue

• To store data permanently

Which invocation method is used by AWS Lambda when integrating with Amazon SQS?

• Synchronous invocation

• Event-driven invocation

• Asynchronous invocation

• Lambda polling

What happens when a Lambda function successfully processes a batch of messages from an Amazon SQS queue?

• The messages are archived

• The messages are deleted from the queue

• The messages are sent to another queue

• The messages are stored in a database

In the context of AWS Lambda and SQS, what does the event JSON file contain?

• User credentials

• Configuration settings

• Batch message details

• Error logs

How does AWS Lambda handle incoming events from Amazon SQS?

• By invoking functions asynchronously

• By sending notifications to users

• By storing events in a database

• By reading messages in batches
