AWS Serverless Microservices with Patterns and Best Practices - Our Serverless Journey with AWS Lambda Invocation Types

The video tutorial explores AWS Lambda invocation types, including synchronous, asynchronous, and event source mapping. It explains their application in developing serverless ecommerce microservices, focusing on communication types. The tutorial covers how to implement these invocation types using AWS services like API Gateway, DynamoDB, and EventBridge, emphasizing their role in creating efficient, event-driven architectures.

What are the three main AWS Lambda invocation types discussed in the course?

• Polling, Real-time, Batch

• Asynchronous, Real-time, Batch

• Synchronous, Batch, Real-time

• Synchronous, Asynchronous, Event Source Mapping

Which AWS service is commonly used with Lambda synchronous invocation?

• AWS SQS

• AWS SNS

• AWS API Gateway

• AWS S3

In asynchronous invocation, how does the Lambda function respond to events?

• It does not respond at all

• Only after manual intervention

• With a delay and no immediate result

• Immediately with a result

Which service is NOT an example of a service using Lambda asynchronous invocation?

• AWS EventBridge

• AWS SNS

• AWS API Gateway

• AWS CloudWatch Logs

What is the primary purpose of event source mapping polling invocation?

• To manage server infrastructure

• To provide real-time data processing

• To integrate with queue-based services

• To execute functions immediately

Which AWS service is used for decoupling microservices in event source mapping?

• AWS SQS

• AWS Lambda

• AWS API Gateway

• AWS S3

How does AWS Lambda interact with services like SQS in event source mapping?

• By pushing events to the queue

• By pulling events from the queue

• By directly executing events

• By storing events in a database
