AWS Serverless Microservices with Patterns and Best Practices - Event-Driven Serverless Microservices Design with AWS La

The video tutorial covers the design and implementation of serverless microservices using AWS Lambda. It emphasizes the importance of event-driven architectures for agility, scalability, and cost optimization. The tutorial explains how Lambda functions handle events and the role of AWS services and design patterns in building distributed applications. It also details the different Lambda invocation types: synchronous, asynchronous, and event source mapping, and their application in microservices communication.

What is one of the main benefits of using AWS Lambda in serverless microservices design?

• Reduced agility

• Increased manual intervention

• Improved scalability

• Higher operational costs

How are AWS Lambda functions typically triggered?

• By manual input

• By scheduled tasks only

• By various events from different resources

• By direct database queries

What is a characteristic of loosely coupled services in event-driven architectures?

• They are tightly integrated with each other

• The event publisher knows all consumers

• They require constant monitoring

• They operate independently of each other

Which AWS service is used for synchronous communication in restful microservices?

• AWS SNS

• AWS API Gateway

• AWS EventBridge

• AWS SQS

In asynchronous communication, what does the client receive after sending a request?

• No response

• Immediate response with results

• Acknowledgement of event receipt

• Error message

What is the purpose of event source mapping in AWS Lambda?

• To schedule tasks

• To directly execute functions

• To map events to specific databases

• To poll event messages from a queue

Which AWS service is used for decoupled microservices and processing events asynchronously?

• AWS Lambda

• AWS SQS

• AWS CloudFront

• AWS RDS
