B) Via scheduled intervals
C) Automatically when data is added to the Kinesis stream
D) When a specific message is manually sent to Lambda

Answer 1

Lambda functions can be triggered by Kinesis stream updates automatically when data is added to the Kinesis stream.

Step-by-step explanation:

Lambda functions can be triggered by Kinesis stream updates automatically when data is added to the Kinesis stream. Kinesis is a real-time data streaming service provided by AWS. When new data is added to a Kinesis stream, Lambda can be configured to automatically execute a function and process that data.

For example, imagine a scenario where sensor data is being continuously ingested into a Kinesis stream. You can create a Lambda function that processes this sensor data as soon as it is added to the stream. This allows you to perform real-time analysis, store the data in a database, or trigger other actions based on the incoming data.

Using Lambda with Kinesis allows you to build powerful, event-driven architectures that can process and react to streaming data in real-time.
