Amazon SNS, or Amazon Simple Notification Service, is a push notification service offered by Amazon. It can send individual messages or broadcast messages to a large number of customers, predominantly on their mobile devices. It can send messages to a variety of platforms, including Kindle Fire and Baidu. Messages can also be sent to other distributed systems.

Features

It uses AWS cloud to automatically scale your workload with your application, enabling it to handle higher throughput.

It can send SMS text messages to customers in over 200 countries.

It supports a variety of mobile platforms, including Apple, Android and email (SMTP). A sender may choose to push messages across multiple platforms using a single code interface.

The sender can create a dead letter queue to store any failed messages (those that weren’t delivered to the subscribed endpoint).

Amazon SNS allows for message filtering. Subscribers only receive those messages that are of interest to them instead of all the messages published for that topic.

Through Amazon Cloudwatch, it allows you to view the system metrics and resolve issues quickly.
