Microsoft Azure 中可用性集的可用区和故障域功能有何区别?
What is a difference between the Availability Zones and Fault domains feature of the Availability Sets in Microsoft Azure?
可用区和可用性集的故障域有什么区别] 在 Microsoft Azure 中?
我正在学习模块 Discuss core Azure architectural components。在那里我遇到了 故障域 :
的描述
Fault domains. Fault domains provide for the physical separation of your workload across different hardware in the datacenter. This includes power, cooling, and network hardware that supports the physical servers located in server racks. In the event the hardware that supports a server rack becomes unavailable, only that rack of servers would be affected by the outage.
此外,还有一些 可用区 功能的解释:
Each availability zone is an isolation boundary containing one or more datacenters equipped with independent power, cooling, and networking.
If one availability zone goes down, the other continues working.
The availability zones are typically connected to each other through very fast, private fiber-optic networks.
Availability zones allow customers to run mission-critical applications with high availability and low-latency replication.
Availability zones are offered as a service within Azure, and to ensure resiliency, there’s a minimum of three separate zones in all enabled regions.
我真的看不出两者之间的区别。这两个概念都是关于单个数据中心内数据中心部分的物理分离。那么,有人可以指出这两个术语的要点是什么吗?他们的意思不一样吗?
我可以这样考虑吗?首先我们有一个区域,这是一个包含几个(至少三个)可用区 (AZ) 的设施,然后每个可用区包含一个或多个数据中心,然后每个数据中心包含一些可用性集,这里我们有每个可用性集合包含几个机架,每个机架代表一个单独的故障域。
我认为可用区是数据中心,一个区域内有多个可用区。故障域可以被认为是在数据中心内(根据您所包含的描述)。域进一步隔离如下所述。
Regions and Availability Zones in Azure
"Azure 区域中的可用区是故障域和更新域的组合。例如,如果您在 Azure 区域中的三个区域中创建三个或更多 VM,则您的 VM 将有效地分布在三个区域中故障域和三个更新域。Azure 平台识别跨更新域的这种分布,以确保不同区域中的 VM 不会安排在同一时间更新。"
