AWS Serverless Microservices with Patterns and Best Practices - Asynchronous Event Sources - Lambda Invocation Types

The video tutorial discusses Lambda invocation types, focusing on the transition from synchronous to asynchronous communication using Amazon Event Bridge. It highlights the benefits of asynchronous processing, such as reduced dependencies and improved responsiveness. The tutorial explains how Amazon Event Bridge facilitates event-driven communication between microservices, specifically in decoupling basket and ordering services. Key concepts include the importance of asynchronous design and the role of Amazon SNS in triggering Lambda functions.

What is the primary benefit of using Amazon Event Bridge for microservices?

• It allows for synchronous communication.

• It increases the complexity of the system.

• It reduces the need for error handling.

• It helps in decoupling microservices.

How does asynchronous processing improve system performance?

• By requiring more logic in the code.

• By reducing the need for parallel processing.

• By increasing dependencies on downstream activities.

• By improving responsiveness back to the client.

Which services are mentioned as tools for triggering Lambda functions asynchronously?

• Amazon CloudFront and Amazon Route 53

• Amazon EC2 and Amazon DynamoDB

• Amazon SNS and Amazon Event Bridge

• Amazon S3 and Amazon RDS

Why is it important for a client to know when a downstream task is completed in asynchronous communication?

• To handle errors upstream.

• To increase the wait time.

• To complete the approximate next steps.

• To ensure the task is repeated.

What role does Amazon Event Bridge play in the context of Lambda Basket microservices?

• It consumes events from the ordering queue.

• It publishes events in a synchronous way.

• It facilitates event-driven asynchronous communication.

• It synchronizes the microservices.
