About Amazon SNS
Amazon Simple Notification Service (SNS) is a highly available, durable, secure, fully managed pub/sub messaging service that enables you to decouple microservices, distributed systems, and serverless applications.
Amazon SNS allows users to push messages to Windows, Google, Apple and certain internet-connected smart devices by using an application programming interface (API) or the AWS Management Console. Once a message is published to the service, it can be sent multiple times to different recipients. Service users also have the flexibility to send direct messages to several devices or to one subscriber by using a sole publish request.
The Files.com integration with Amazon Simple Notification Service (Amazon SNS) allows you to trigger a a notification on Amazon SNS whenever certain actions occur on a folder.
