保持规模将VM设置在同一区域区域？ [英] Keeping scale set VMs in the same regional zone?

问题描述

我们需要三个可以将流量负载平衡到SQL AG的应用虚拟机。

We want three app VMs which can load balance traffic to a SQL AG.

我们是否应该创建一个连接到SQL AG的比例集。 如果我们将可用区的默认设置保留为空白？， 它表示，如果我选择一个可用区域来部署比例集，则托管磁盘和公共IP（如果有的话）将在
中创建与比例设置相同的可用区域。   我不明白这句话，因为所有流量都在域内，那么公共IP是什么？ 如果我选择与不选择可用区域，？托管磁盘在不同的
区域而不是比例设置的结果是什么？

Should we create a scale set to connect to the SQL AG.  If we keep the default setting for availability zone to blank?,  it says if I choose a avail zone to deploy the scale set the managed disk and public IP (if you have one) will be created in the same avail zone as your scale set.   I do not understand this statement because all traffic is within the domain so what is the public IP for?  What is the consequence if I choose versus do not choose the avail zone?,.. managed disk in different zone than the scale set?

比例集中的三个VM和SQL AG可以在相同的可用区域（即区域1）中创建。   这种规模与我创建三个不在规模集中的IaaS应用服务器并将它们置于LB后面的情况有何不同？ 在这种情况下使用比例集是否有任何
的优势？   我的选择是选择简单易用的选项吗？

The three VM in the scale set and SQL AG can be created in the same avail zone (ie zone 1).   How is is this scale different than if I create a three IaaS app servers which are NOT in a scale set and place these behind a LB?  Are there any advantages for using a scale set in this case?   My preference is to choose option which is simple and easiest to manage?

推荐答案

配置VM规模集的方式与配置Azure VM的方式不同。特别是，在这种情况下，您可能希望使用Azure VM（VM规模集通常用于无状态工作负载）。 

The way you configure a VM scale set is different from the way you configure Azure VMs. In particular, in this case, you would want to use Azure VMs (VM scale sets are, in general, intended for stateless workloads). 

您不需要公共IP除非您想将您的SQL AG暴露给互联网 - 这不太可能

You don't need a public IP unless you want to expose your SQL AG to Internet - which is not likely
