# RapidIdentity SMS Gateway

RapidIdentity SMS Gateway utilizes Amazon Simple Notification Service (SNS).

The AWS global infrastructure is built around AWS Regions and Availability Zones. AWS Regions provide multiple physically separated and isolated Availability Zones, which are connected with low-latency, high-throughput, and highly redundant networking. Availability Zones are more highly available, fault-tolerant, and scalable than traditional single or multiple data center infrastructures. The Amazon service that provides SMS capability, Amazon Simple Notification Service (SNS), is localized to the specific AWS region where customer resources are hosted. SNS leverages the AWS global infrastructure to provide resilience within that region.
