交通管理员冗余问题 [英] Traffic Manager Redundancy Question

问题描述

您好，

我有关于流量管理器服务可用性的问题。有关互联网的信息令人困惑，我希望有人可以为我澄清这一点。

以下链接中的冗余建议表明流量管理器可能会失败，并且有备份服务到位。但是，如果流量管理器是全局部署的，那么失败的具体方法是什么？我知道当我们部署配置文件时，meta
数据被固定到一个区域，我认为这意味着元数据是"活动的"。在一个地区，但仍在全球范围内复制。

堆栈溢出也很混乱。

问题是，如果这是一项全球服务，那么它需要什么呢？为什么微软会为全球部署的服务推荐一项备份服务，当然这需要一些流行病全球性的失败？具体而言，此服务中的弱点
需要配置备份服务？

解决方案

任何在线公司都会疯狂且无法提供100％SLA，因此他们必须推荐备份，这是99.999％。

Hi there,

I've got a q regarding the availability of the traffic manager service. There is confusing information about the internet, I hope someone can clarify this for me.

The recommendations for redundancy in the below link suggests traffic manager can fail, and to have a backup service in place. However, if traffic manager is globally deployed, what specifically does it take to fail? I know when we deploy a profile the meta data is pinned to a region, I assume this means the meta data is "active" in a region but is still replicated globally.

People on stack overflow are also confused.

The question is, if this is a global service, what does it take for it to go down? How come Microsoft recommend a backup service for a globally deployed service, surely this would require some epidemic global failure? What specifically is the weak point in this service that requires a backup service to be provisioned?

解决方案

Any online company would be crazy to and cannot provide 100% SLA, it's 99.999% therefore they have to recommend a backup.
