您是否需要 2 个 Azure 网站实例来实现 SLA (如 Web 角色)?

Do you need 2 instances of Azure websites for SLA like Web Roles?(您是否需要 2 个 Azure 网站实例来实现 SLA (如 Web 角色)?)

问题描述

在云服务 Web 角色上，您必须创建至少 2 个实例才能获得 Azure 的 99.95% SLA，因为当它们更新服务器的操作系统等时，Azure 将需要重新启动机器(一次一个).这是有据可查的，当您运行单实例 Web 角色时，您会被门户网站大喊大叫.

On cloud services web roles you must create at least 2 instances to get Azure's 99.95% SLA because when they do updates to the servers' OS etc, Azure will need to restart the machines (one at a time). This is well documented and you will be shouted at by the portal when running a one instance web role for doing this.

对于 Azure 网站，您不会收到此类警告，而且我找不到任何文档建议 99.9% SLA 的 2 个实例.但是，我也找不到任何文档说明您不需要此 SLA 需要 2 个实例.

With Azure websites you don't get such warnings and I cannot find any documentation suggesting 2 instances for the 99.9% SLA. However, I also can't find any documentation saying that you don't need 2 instances for this SLA.

那是什么?我是否需要 2 个实例来实现 Azure 网站的 SLA (例如 Web 角色)，或者这已成为过去?

So which is it? Do I need 2 instances for Azure websites' SLA like web roles or is that a thing of the past?

推荐答案

Azure 网站团队的一位开发人员在此回复 那个

A developer on the Azure Websites team has replied here that

基本或标准层的任何 Azure 网站的 SLA 为 99.95%

the SLA for any Azure Website on the Basic or Standard tier is 99.95%

只有一个网站实例就足够了

Just having one instance of the site is enough
