azure - 使用 Azure 垂直扩展时是否会涉及停机时间？

Question

我在带有 WHM/cPanel 和 MySql 的虚拟机上有两个网站。

我希望将其移至 Azure 并使用垂直缩放。网站的访问量通常很稳定，但每年有三四次流量大幅增加，这在历史上给现有主机带来了很大的问题。

我希望将其移至 A5-A7 系列服务器中以实现垂直扩展。

我无法在任何地方找到有关当 Azure 将我的虚拟机从 A5 扩展到 A6 或其他情况时是否涉及任何停机时间的任何信息。

有没有人有这方面的经验，并且可以给我一个明确的答案，即使用垂直缩放时是否会出现停机，以及如果涉及任何停机，那么我期望的停机时间是哪种

感谢您的宝贵时间。

是的，它会导致停机。 Post on it

Azure 将重新启动您的虚拟机。

引自页面(我突出显示了重要的部分):

When considering the ability to resize virtual machines there are three key concepts that will impact how simple it is to change the size of your VM.

1. The region in which your VM is deployed. Different VM sizes require different physical hardware. In some instances, an Azure region may not contain the hardware required to support the desired VM size. All Azure regions support the VM sizes Standard_A0 – A7 and Basic_A0 – A4. You can then find which other VM sizes are supported in each region under the Services tab of the Azure Regions web page.

2. The physical hardware currently hosting your VM. If the physical hardware currently running your virtual machine also supports your desired new size, then it is very easy to change the VM size through a simple size change operation which results in a VM reboot.

3. The deployment model used for the VM. The two deployment models are Classic and Resource Manager. The Resource Manager model is the newer model, and it supports some ease of use functionality not available in the classic deployment model.
