Amazon CloudWatch Synthetics enables you to create canaries to monitor your endpoints and APIs. Canaries are configurable scripts that follow the same routes and perform the same actions as a customer. This enables the outside-in view of your customers’ experiences, and your service’s availability from their point of view.
