AWS Serverless Microservices with Patterns and Best Practices - API Gateway as a Lambda Synchronous Event Sources

The video tutorial explains the role of API Gateway as a synchronous event source for AWS Lambda. It highlights the advantages of synchronous commands, such as immediate response, and discusses their use in CRUD operations. The tutorial also covers the disadvantages of synchronous communication, including potential blocking and timeouts. Finally, it emphasizes API Gateway's effectiveness as a synchronous trigger for AWS Lambda, especially in API management and serverless microservices development.

What is the primary role of API Gateway in relation to AWS Lambda?

• To act as a synchronous event source

• To provide a serverless API proxy

• To handle user authentication

• To manage database connections

Which operations are commonly associated with synchronous commands?

• Data encryption and decryption

• Create, read, update, delete (CRUD)

• User login and logout

• File upload and download

What is one advantage of using synchronous commands in API Gateway?

• Delayed response to API calls

• Increased data storage capacity

• Immediate response to API calls

• Enhanced security features

What is a potential disadvantage of synchronous communication?

• It always requires a database

• It can block the process if downstream services fail

• It is more expensive than asynchronous communication

• It cannot handle large data volumes

How does API Gateway assist in API management for AWS Lambda?

• By providing a synchronous trigger

• By storing large datasets

• By encrypting all data

• By managing user sessions
