A company requires a daily analysis of sales reports from multiple branch offices, which are uploaded to an Amazon S3 bucket. They have an AWS Lambda function to process these reports and store results in a database. Identify the most cost-effective method to trigger this analysis at a specific daily time.
Explanation:
The most cost-effective solution is to create an Amazon EventBridge scheduled rule to invoke the Lambda function once each day at the predefined time. EventBridge makes it easy to create timed events that can trigger AWS services like Lambda. This avoids the costs associated with continuously running the Lambda function (Option C) and eliminates the complexity of using AWS Step Functions (Option B). Option A is less suitable because it relies on the timing of report uploads rather than a specific daily schedule.
