What Company Is Offering:
Amazon Simple Notification Service is a web service that makes it easy to set up, operate, and send notifications from the cloud. It provides developers with a highly scalable, flexible, and cost-effective capability to publish messages from an application and immediately deliver them to subscribers or other applications. It is designed to make web-scale computing easier for developers.
How It Works:
It provides a simple web services interface that can be used to create topics you want to notify applications (or people) about, subscribe clients to these topics, publish messages, and have these messages delivered over clients’ protocol of choice . Amazon SNS delivers notifications to clients using a “push” mechanism that eliminates the need to periodically check or “poll” for new information and updates. Amazon SNS can be leveraged to build highly reliable, event-driven workflows and messaging applications without the need for complex middleware and application management.
Create a topic: A topic is an “access point” – identifying a specific subject or event type – for publishing messages and allowing clients to subscribe for notifications. Once a topic is created, the topic owner can set policies for it such as limiting who can publish messages or subscribe to notifications.
