B系列 - 有人可以解释基本的CPU性能吗？ [英] B-Series - Can someone explain the base CPU preformance?

问题描述

我一直在使用B系列虚拟机，主要是轻载网站。 我刚刚部署了一个在其上运行小型数据库的新VM。  VM是B2MS，因此CPU基线为60％ 我从MS文档
中了解到，如果VM运行低于此基线，它将获得积分，当它突然爆发时，它将消耗它们。  

此虚拟机的平均运行率（Azure门户统计数据）约为28％（每小时爆发一次至60％）但所有积分已被消耗，而且不是生成任何新的，因此它被扼杀（如预期）。 是否有某种
人工计算器会给我一个精确的消耗率与CPU负载？

感谢任何帮助。

我们在B系列上有很多文档  ;

< a href ="https://docs.microsoft.com/en-us/azure/virtual-machines/linux/b-series-burstable"> https://docs.microsoft.com/en-us/azure/virtual -machines / linux / b-series-burstable

https://docs.microsoft.com/en-us/azure/virtual-machines/linux/compute-benchmark-scores#b---burstable

我们在Azure定价计算器中也有B系列

我可以理解尝试计算虚拟机的成本可能很难。 

如果虚拟机在基线下运行，你是对的你应该获得积分的CPU。然后，这些信用将用于根据需要提高CPU功率，而不是扩展到更大的大小或更多实例。因此，无论您运行VM，成本应该基本上都是
。这意味着每小时的直接成本。我们只是将这些机器的价格降低，因为CPU性能可能会有所不同，因此只对某些工作负载有意义。

Hi,

I've been using B series VMs for a little while and mostly on light load websites.  I've just deployed a new VM that has a small database running on it.  The VM is a B2MS so has a CPU baseline of 60%  I understood from the MS documentation that if the VM was running below this baseline it would earn credits and when it burst over that it would then consume them.  

This VM is running at an average (Azure portal stats) of about 28% (with bursts to 60% about once an hour) but all the credits have been consumed and it's not generating any new ones hence it is being throttled (as expected).  Is there some kind of human-fied calculator out there that will give me an acurate consumption rate vs CPU loading?

Any help gratefully received.

We have quite a few docs on the B series 

https://azure.microsoft.com/en-us/blog/introducing-b-series-our-new-burstable-vm-size/

https://docs.microsoft.com/en-us/azure/virtual-machines/linux/b-series-burstable

https://docs.microsoft.com/en-us/azure/virtual-machines/linux/compute-benchmark-scores#b---burstable

We also have the B-Series in the Azure Pricing Calculator

I can understand trying to calculate what the VMs will cost can be hard. 

You are correct that if the VM is running under the baseline CPU you should be acquiring credits. Those credits will then be spent to up the CPU power as needed instead of scaling out to larger sizes or more instances. So the cost should be essentially be however long you are running the VM. Which means a straight cost per hour. We simply price these machines lower as the CPU performance can vary so it only makes sense for certain workloads.
