Availability zones
At its initial stage, the Yandex Cloud platform is hosted in three Yandex data centers located in different areas of Russia (the Vladimir, Ryazan, and Moscow regions). The Yandex Cloud infrastructure in each data center is called an availability zone. Each zone is isolated from hardware and software failures that may occur in other availability zones. By deploying your apps in multiple zones, you ensure fault tolerance and significantly reduce the risk of data loss.
You can host resources in the following availability zones:
ru-central1-a;ru-central1-b;ru-central1-c(with limitations — see the details).
Note
When new availability zones appear or existing ones change location, Yandex Cloud notifies all its customers.
Yandex Cloud resources are either zonal (linked to an availability zone) or global (not linked to zones).
Zonal resources include virtual machines and disks. Global resources include cloud networks and buckets.
