Features

• Every get request to /order generates an item in the database
• each change in the database is triggering a lambda that checks the database change and then publish a event with the order details and a url for email reviever to confirm the delivery
• a event rule forwards all order events to a SNS topic which sents an email to the configured email address (maybe check spam folder)
• once the user click the link in the email the second apigateway endpoint is triggered which updates the status in the database
• all events are logged to a loggroup
