Scenario: You are tasked with setting up an architecture where changes to items in an Amazon DynamoDB table should trigger AWS Lambda functions to update corresponding records in an Amazon RDS database. What steps would you take to implement this solution?

  • Use Amazon EC2 Instances
  • Use Amazon S3 Event Notifications
  • Use DynamoDB Streams
  • Use DynamoDB Triggers
DynamoDB Streams can capture changes to items in a table and trigger AWS Lambda functions, allowing you to update corresponding records in RDS.
