Today in a group to see a netizen sent a problem, the problem is described as follows:Build four VMs on Windows Azure, all four machines are highly availableTurn off three after doing a good job, leaving a production, when the number of users to access large cup demand will increase, to a certain threshold after the automatic opening of a set of one more and then open a set, analogy downAutomatically shuts down a VM when the CPU drops to a certain thr
using PowerShell Directmanaging VMS from Hyper-V hostsWith PowerShell Direct, we don't have to worry about network or firewall restrictions because it works regardless of the network or remote management configuration. So, a lot of friends will ask, since it is not through the network and firewall that is how to connect it? In fact PowerShell's connection is via VMBus instead of through the network.Before PowerShell direct, I used remote PowerShell, R
Windows Azure Platform Family of articles Catalog Please note: The virtual machines that we create on Azure are accessible through the public IP address. (directly via the virtual machine's IP address: PIP, or via the load Balancer's IP address: VIP)But there will always be malicious hackers who attack these VMs. So it's important to protect azure virtual machines. In the case of a Linux virtual machine, I strongly recommend using SSH key to access

Set the gate gateway to connect two VMS. 1. Prepare before the experiment. 1. clone two VMS. When vm1 is not started, select VM-> clone... and select full clone. Repeat once. Rename them to vm2 and gate respectively. 2. When the network interface gate is not started, VM-> Settings-> Add: Ethernet2 3. Configure host VM-> Settings, and select network connection: host interface connection vm1 Ethernet M m-> VM
in the production environment, the server memory overflow, suspended animation or thread deadlock, etc., cause the service to be unavailable. The workaround that we often use is to analyze the error diary and then find out where the code is going to go wrong, which might work, but it takes a lot of time to troubleshoot, or the code itself is not wrong, but it consumes too much memory when the traffic is large. Garbage objects are not in time to recover and so on other circumstances, so it is ext

Creating a VM from uploaded VHDsAs I mentioned above you can specify a disk to boot from instead of provisioning from an image. The PowerShell code to does is simple. You can of course add disks and endpoints in between New-azurevmconfig and NEW-AZUREVM as well.
