AWS Cloud Development Kit - From Beginner to Professional - Serverless Stream Processor Architecture with Kinesis

What is a key benefit of using serverless data stream processors?

• They are only suitable for mobile applications.

• They require no backend processing.

• They allow capturing and processing of user activities in real-time.

• They eliminate the need for data storage.

In the architecture overview, what is the role of the Kinesis data stream?

• To store data permanently.

• To process data on the frontend.

• To receive and manage data streams from the frontend.

• To replace the need for a database.

What is the purpose of the Lambda function in the simple setup described?

• To delete data from the S3 bucket.

• To write processed data into an S3 bucket.

• To generate user interface elements.

• To manage user authentication.

What is the first step in building the architecture using AWS CDK?

• Setting up a database.

• Configuring user permissions.

• Creating a Kinesis data stream.

• Creating a Lambda function.

Why is it important to set a retention period for the Kinesis data stream?

• To increase the data throughput.

• To control how long data is retained before deletion.

• To manage the data processing speed.

• To ensure data is stored indefinitely.

What is a crucial step when creating Lambda functions for data processing?

• Ensuring the Lambda function has permissions to access necessary resources.

• Setting the Lambda function to run indefinitely.

• Using the Lambda function to manage user sessions.

• Configuring the Lambda function to send emails.

What is the purpose of creating log groups for Lambda functions?

• To store user data.

• To manage application settings.

• To track and manage logs for debugging and monitoring.

• To enhance the user interface.

During testing, what is a common issue that might prevent data from being written to the S3 bucket?

• Exceeding the data storage limit.

• Insufficient permissions for the Lambda function.

• Network connectivity issues.

• Incorrect data format.

What is the role of the producer Lambda function in the architecture?

• To delete data from the S3 bucket.

• To manage user authentication.

• To generate and send data to the Kinesis stream.

• To consume data from the Kinesis stream.

What should be done if the Lambda function is not writing data to the S3 bucket?

• Increase the Lambda function timeout.

• Restart the AWS CDK stack.

• Change the data format being processed.

• Check and update the permissions for the Lambda function.
