Azure维护：8个实例可能会停机？

[英]Azure maintenance: possible downtime with 8 instances?

原文 2014-08-08 08:46:28 8 1 azure/ configuration/ cloud

Microsoft just sent out an email notifying our company that there will be scheduled maintenance for our Windows Azure environment. Microsoft刚刚发送了一封电子邮件，通知我们公司将对Windows Azure环境进行定期维护。

We will be performing maintenance on our networking hardware. 我们将对我们的网络硬件进行维护。 We are scheduling the update to occur during nonbusiness hours as much as possible, in each maintenance region. 我们计划将更新尽可能在每个工作区域的非工作时间进行。 Single and multi-instance Virtual Machines and Cloud Services deployments will reboot once during this maintenance operation. 在此维护操作过程中，单实例和多实例虚拟机和Cloud Services部署将重新引导一次。 Each instance reboot should last 30 to 45 minutes . 每个实例重新启动应持续30到45分钟 。 We suggest using availability sets in the architecture to protect against downtime caused by planned maintenance. 我们建议在体系结构中使用可用性集 ，以防止计划内维护导致的停机时间。 This maintenance will proceed by updating instances in only one Fault Domain (FD) at a time for the Cloud Services and Virtual Machines in an Availability Set. 维护将通过一次仅针对一个可用性集中的Cloud Services和虚拟机更新一个故障域（FD）中的实例来进行。

Now our website consists of a Cloud Service with 8 (small) instances of a web role. 现在，我们的网站包括一个Cloud Service，其中包含8个（小型） Web角色实例。 With these 8 instances, is there still a possibilty of downtime for the website? 有了这8个实例，网站是否仍有停机的可能性？ Do we need to use 'Availability Sets' or are we safe? 我们需要使用“可用性集”还是安全的？ Thanks for any info.. 感谢您提供任何信息。

Depends on which service you're referring to. 取决于您所指的服务。 From my understanding, because you mentioned "Web Role", you're talking about Cloud Services (PaaS). 据我了解，因为您提到了“ Web角色”，所以您在谈论云服务（PaaS）。

In General: 一般来说：

If you have Cloud Services (PaaS), which is what you have based on my understanding, then you won't have any downtime, no. 如果您拥有基于我的理解所拥有的云服务（PaaS），那么您将不会有任何停机时间。
If you have VMs (Virtual Machines) that don't belong to the same Availability Set, then there is a chance of downtime. 如果您拥有的虚拟机（虚拟机）不属于同一可用性集，则可能会造成停机。 To fix that, just make sure they are on the same Availability Set. 要解决此问题，只需确保它们在同一可用性集上即可。 If you don't have VMs, ignore this. 如果您没有VM，请忽略此操作。
