SNS

A service for managing sending messages to end subscribers, which can be servers, e-mail addresses, Amazon SQS queues, or physical devices. The user can create and control access to a topic, defining which subscribers can communicate with a given topic. Thanks to this, the sample message is connected with the subject and not with the subscriber — Amazon SNS identifies the list of subscribers of a given topic and sends them a message, greatly facilitating the management of messages. Messages can be sent via many different channels, such as e-mail, SMS, or push notifications.
