+Jack in the Cloud is a service that delivers scheduled notifications. It offers three operations: `CreateTimer`,
+`UpdateTimer`, and `CancelTimer`. Each `Timer` comes with a `type`, `payload`, and `fireAt` timestamp. Whenever a
+`Timer` is set to fire (at `fireAt`), the `payload` is delivered to the target specified during deployment for the given
+`type`. Target can be anything that can subscribe to SNS topic, so: SQS, Lambda, HTTP endpoint, etc.
