Resilience in Amazon Personalize
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.
Amazon Personalize leverages the Amazon global infrastructure for data resiliency. When you create
an Amazon Personalize resource in an Amazon Region, Amazon Personalize manages the resilience and data redundancy of the
resource across multiple Availability Zones.
