What is an automated and serverless way to invoke the function?
Deploy an Amazon EC2 instance based on Linux, and edit its /etc/crontab file by adding a command to periodically invoke the Lambda function.
Configure an environment variable named PERIOD for the Lambda function. Set the value to 600.
Create an Amazon EventBridge (Amazon CloudWatch Events) rule that runs on a regular schedule to invoke the Lambda function.
Create an Amazon Simple Notification Service (Amazon SNS) topic that has a subscription to the Lambda function with a 600-second timer.
Explanations:
An EC2 instance is not serverless, and using crontab to invoke a Lambda function requires an EC2 server, which is not scalable or efficient for this use case.
Setting an environment variable does not schedule or invoke Lambda functions. Environment variables are used for configuration purposes, not for timing events.
Amazon EventBridge (formerly CloudWatch Events) allows scheduling Lambda function invocations at regular intervals, making it an automated and serverless solution for invoking a Lambda function every 10 minutes.
SNS alone cannot directly schedule a Lambda invocation. SNS triggers are event-based, and while it could invoke Lambda, it does not provide scheduling functionality like EventBridge.
I think the answer is:
Create an Amazon EventBridge (Amazon CloudWatch Events) rule that runs on a regular schedule to invoke the Lambda function.
