Simple Notification Service, or SNS, is AWS’s publish/subscribe notification service for the mass delivery of messages. SNS acts as a single message bus that can be sent to a variety of devices and platforms through a single code interface. It is also possible to adapt message formats to the particular needs of each platform.
Scaleway has developed its own service based on AWS SNS protocol. Scaleway Topics and Events does not have any dependencies on the AWS SNS infrastructure or offering, we use our own stack which is fully self-hosted and developed in-house.
