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.
Many of the messages that you can send with SNS are relevant or valuable for a limited period of time. With Cross platform Time to Live (TTL), Amazon SNS allows developers to set a time value of up to two weeks for time-specific app messages. If a recipient’s device does not become available by the end of the time value, the message expires since it is no longer relevant.
