英文:
How do I get the Availability Domain of a VM instance in GCP?
问题
我只使用过OCI。在GCP中是否有与其可用性域概念相当的东西？
我已经查看了GCP的用户界面和GCP Golang客户端库的响应，但除了实例部署的区域之外，没有找到相关的内容。我已经阅读了GCP的关键术语页面和其他文档，现在只是想知道GCP是否存在类似的概念。
英文:
I've only ever worked with OCI. Is there an equivalent to their Availability Domain concept in GCP?
I have been looking through the UI and the responses from the GCP Golang Client Libraries but have found nothing relevant besides the zone which the instance is deployed in. I've read GCP's key terminology page and other documentation and am now just wondering if a concept like this even exists in GCP.

一个OCI区域与Google Cloud区域是相同的。一个OCI可用性域与Google Cloud区域是相同的。在网络处理方面有一些差异，但对于大多数目的来说，映射非常接近。
所有云供应商都使用类似的结构 - 一个区域由多个地理上分隔的数据中心组成，以隔离本地故障：地震、电力、恶劣天气、火灾等。
注意：对于某些供应商的某些区域，每个区域只有一个数据中心。随着他们在这些地区的业务增长，供应商通常计划添加更多的数据中心。对于这些地区，一个数据中心等于一个区域/可用性域。
英文:
An OCI region is the same as a Google Cloud region. An OCI availability domain is the same as a Google Cloud zone. There are some differences in how networking is handled, but for most purposes, the mapping is very close.
All of the cloud vendors use similar constructs - a region consists of multiple data centers separated geographically to isolate local failures: earthquakes, power, severe weather, fires, etc.
Note: in some regions for some vendors, there is only one data center per region. As their business grows in those areas, the vendors usually have plans to add more data centers. For those areas a data center == zone/availability-domain == region.
