Design Microservices Architecture with Patterns and Principles - Event-Driven Serverless Microservices Design with AWS L

The video tutorial covers the design and implementation of event-driven microservices using AWS Lambda. It explains the benefits of event-driven architecture, such as agility and scalability, and how AWS Lambda fits into this model by handling events from various sources. The tutorial discusses different invocation types, including synchronous, asynchronous, and event source mapping, and how they apply to microservices communication. It also highlights design patterns and best practices for building serverless applications, particularly in the context of an e-commerce application.

What is one of the main benefits of using AWS Lambda in event-driven architectures?

• Increased manual intervention

• Reduced agility

• Higher operational costs

• Improved scalability

How does AWS Lambda handle events in an event-driven architecture?

• By ignoring them

• By triggering functions

• By storing them indefinitely

• By converting them to logs

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

• They are aware of all consumers

• They are tightly integrated

• They operate independently

• They require constant monitoring

Which AWS service is commonly used with Lambda for API management?

• Amazon S3

• AWS CloudFront

• AWS API Gateway

• Amazon RDS

What is the synchronous communication model in AWS Lambda?

• The client sends a request and receives a delayed response

• The client sends a request and receives multiple responses

• The client sends a request and receives no response

• The client sends a request and waits for a response

In asynchronous communication, what does the client receive?

• A real-time update

• An acknowledgment of receipt

• An error message

• A detailed response

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

• To convert events to logs

• To store events permanently

• To poll event messages from a queue

• To ignore events
