AWS Serverless Microservices with Patterns and Best Practices - Catch and Process Async EventBridge Invocation and Sync

The video tutorial explains how to handle asynchronous and synchronous invocations in AWS Lambda functions. It covers the understanding of event sources, such as Amazon EventBridge and API Gateway, and how to develop microservices to process these events. The tutorial includes writing pseudo code to differentiate between asynchronous and synchronous invocations, and emphasizes the importance of returning a synchronous response to avoid errors. The video concludes with a plan to implement the discussed methods in future videos.

What are the two types of invocations discussed in the video?

• Manual and Automatic

• Direct and Indirect

• Static and Dynamic

• Synchronous and Asynchronous

What is the purpose of the event JSON object in asynchronous invocations?

• To store user data

• To manage API keys

• To define the structure of the event

• To log errors

How can you identify an asynchronous invocation?

• By looking for a detail type attribute

• By checking the event source

• By verifying the event size

• By analyzing the event timestamp

Which method is used to handle asynchronous invocations?

• Event.get()

• API Gateway.invoke()

• Lambda.asyncInvoke()

• Event.detailType()

What is the role of the pseudo code in the video?

• To explain API key management

• To show how to write unit tests

• To illustrate the invocation process

• To demonstrate error handling

What should be included in a synchronous response to avoid errors?

• User credentials

• Status code and body information

• Event ID and timestamp

• API key and secret

What happens if a synchronous response is not returned correctly?

• An internal server error occurs

• The event will be ignored

• The function will execute twice

• The API Gateway will shut down
