Amazon Simple Notification Service (Amazon SNS) is a notification service provided as part of Amazon Web Services since 2010. It provides a service for sending messages.[1]

Amazon SNS acts as a single message bus that can message to a variety of devices and platforms.[2] A single code interface can address all of these equally, or message formats can be tailored to the particular needs of each platform.[3] Amazon SNS can also deliver messages by SMS to 200+ countries.[4]


Amazon SNS uses the publish/subscribe model for delivery of messages.[1] Recipients subscribe to one or more 'topics' within Amazon SNS. This may be hidden from the user as an internal part of a mobile app.[5] Receipt of a message may also be hidden from the user: this service is largely aimed at the internal processing of specific apps rather than as a generic email substitute. A game might receive bonus-level announcements or unlock keys for in-game purchases by this route. A ticket booking app could use it for confirmation vouchers, boarding passes or notifications of a delay to a flight.
