Amazon Simple Notification Service (Amazon SNS) is a fast, flexible, fully managed push messaging service. Amazon SNS makes it simple and cost-effective to push notifications to Apple, Google, Fire OS, and Windows devices, as well as Android devices in China with Baidu Cloud Push. You can also use SNS to push notifications to internet connected smart devices, as well as other distributed services.
Besides pushing cloud notifications directly to mobile devices, Amazon SNS can also deliver notifications by SMS text message or email, to Amazon Simple Queue Service (SQS) queues, or to any HTTP endpoint.
To prevent messages from being lost, all messages published to Amazon SNS are stored redundantly across multiple availability zones.
Amazon SNS lets you push messages to mobile devices or distributed services, via API or an easy-to-use management console. You can seamlessly scale from a handful of messages per day to millions of messages or higher.
With SNS you can publish a message once, and deliver it one or more times. So you can choose to direct unique messages to individual Apple, Google or Amazon devices, or broadcast deliveries to many mobile devices with a single publish request.
SNS allows you to group multiple recipients using topics. A topic is an “access point” for allowing recipients to dynamically subscribe for identical copies of the same notification. One topic can support deliveries to multiple endpoint types -- for example, you can group together iOS, Android and SMS recipients. When you publish once to a topic, SNS delivers appropriately formatted copies of your message to each subscriber.
Amazon SNS has no upfront costs and you can pay as you go. It costs $1.00 to send one million notifications via push messaging. Click here for more information about pricing.
