Availability zones
An availability zone is an infrastructure within a data center that hosts Yandex Cloud. Yandex Cloud resources are either zonal (linked to an availability zone) or global (not linked to any zone). Zonal resources include virtual machines and disks. Global resources include cloud networks and buckets.
Each zone is isolated from hardware and software failures that may occur in other availability zones. By deploying your applications to multiple zones at the same time, you ensure their fault tolerance and significantly reduce the risk of data loss.
The Yandex Cloud platform is hosted in four Yandex data centers located in the Vladimir, Ryazan, Moscow, and Kaluga regions. You can host resources in the following availability zones:
ru-central1-a
ru-central1-b
ru-central1-c
(being deprecated)ru-central1-d
Note
When new availability zones appear or existing ones change location, Yandex Cloud notifies all its customers.
