Cloud Messaging

Cloud Messaging is a service that enables the delivery of messages between applications, devices, and servers over the internet, typically using push notifications or in-app messaging. It provides reliable, scalable, and secure communication for real-time updates, alerts, and data synchronization across distributed systems. Common implementations include Firebase Cloud Messaging (FCM), Amazon Simple Notification Service (SNS), and Apple Push Notification Service (APNS).

Also known as: Push Notifications, Message Queuing, Notification Services, FCM, APNS

Why learn Cloud Messaging?

Developers should learn Cloud Messaging when building applications that require real-time notifications, such as mobile apps for news alerts, chat applications, or IoT devices sending status updates. It is essential for enhancing user engagement by delivering timely information without requiring users to manually refresh the app, and it helps in scenarios like sending transactional emails, marketing campaigns, or system alerts in enterprise software.
