What is the term for the geographical segmentations that cloud service providers often implement for resiliency and compliance?

The term "regions" refers to the geographical segmentations that cloud service providers set up to enhance resiliency and ensure compliance with various regulatory requirements. Regions are essentially large areas that encompass multiple data centers situated in proximity to one another. These regions allow providers to deploy services in a way that optimizes performance and redundancy.

By distributing resources across different regions, cloud providers can offer high availability and disaster recovery solutions, as data can be replicated and services can be maintained even if one location experiences failure. Furthermore, compliance with local laws and regulations regarding data residency can be achieved more easily when services are deployed within designated geographic areas.

While availability zones also contribute to resiliency by providing distinct, isolated locations within a region, the broader term "regions" captures the overall geographical strategy. Autoscaling groups pertain more to managing and scaling compute resources rather than geographical segmentation. Global DNS affinity relates to routing user requests based on geographic or performance considerations but does not specifically pertain to the physical layout of cloud resources in geographic terms. Thus, "regions" accurately reflects the concept of geographical segmentation for resiliency and compliance in cloud services.
