SNS

A service for managing the sending of messages to end subscribers, which can be servers, e-mail addresses, Amazon SQS queues or physical devices. The user can create a topic and control access to it, 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 itself identifies the list of subscribers of a given topic and sends them a message, which greatly facilitates the management of messages. Messages can be sent via many different channels, such as e-mail, SMS or push notification.
