Resilience in Amazon SNS
The Amazon global infrastructure is built around Amazon Regions and Availability Zones. Amazon
Regions provide multiple physically separated and isolated Availability Zones, which are
connected with low-latency, high-throughput, and highly redundant networking. With
Availability Zones, you can design and operate applications and databases that
automatically fail over between zones without interruption. Availability Zones are more
highly available, fault tolerant, and scalable than traditional single or multiple data
center infrastructures. For more information about Amazon Regions and Availability Zones,
