This means that devices such as the iPhone and applications like iCal on the Mac can receive a notification

The Apple Push Notification Service (APNS) is a service created by Apple Inc.

It is the centerpiece of the remote notifications feature, and was launched together with iOS 3.0 on June 17, 2009. APNS is used to send notifications to applications on Apple devices (iOS, tvOS, macOS, watchOS) that have registered to receive those notifications.

Apple push notification service is a cloud service which allows to send notifications from any back-end server to an API provided by Apple. Apple has recently introduced an HTTP/2 API to send the push notifications which is the recommended way from Apple.

Third-party service providers offer a higher level interface to Apple API, making it easier to handle notification for a large number of registered devices.
