ما معنى Availability zone, availability-zone identifier؟

يُعرف أيضًا باسم: availability zone · availability-zone identifier

Definition 16.2 Networks, Hardware and Trading Infrastructure · الفصل 16 — Trading in a Public Cloud

An availability zone is one of the isolated groups of data centres that make up a cloud region, with its own power, cooling and networking, connected to the region’s other zones by low-latency links. Its availability-zone identifier is the provider’s code for the physical zone, the same in every account, as distinct from the zone’s name, which the provider may assign differently in each account.

Zone names against zone identifiers for two accounts, from the chapter’s fixtures (the documented response shape of the provider’s describe-availability-zones call, with synthetic values; four of the six zones shown). The firm reads the venue’s zone identifier, not its name.
