AWS Serverless Microservices with Patterns and Best Practices - Polling Events and Event Source Mappings - Lambda Invoca

The video tutorial covers Amazon AWS SQS and Lambda invocation types, focusing on synchronous and asynchronous communication. It explains event source mapping, polling communication, and how Amazon SQS can be used to decouple microservices. The tutorial also discusses the use of queues and streams as polling event sources to support asynchronous processing.

What are the two types of communication mentioned in the context of Lambda invocation?

• Push and Pull

• Direct and Indirect

• Real-time and Batch

• Synchronous and Asynchronous

What is the primary purpose of using Amazon SQS in microservices architecture?

• To decouple microservices

• To reduce costs

• To enhance security

• To increase the speed of data processing

In the context of event source mapping, what does polling communication involve?

• Consumers waiting for producers to push messages

• Real-time data streaming

• Consumers polling producers for messages in batches

• Producers sending messages directly to consumers

Which AWS service is used as a queue event source for Lambda functions?

• Amazon SNS

• Amazon SQS

• Amazon RDS

• Amazon EC2

What is the role of queues and streams in polling event sources?

• To enhance data security

• To buffer incoming Lambda requests

• To reduce latency

• To provide real-time data processing
