  Plan for maintenance and downtime There are three scenarios that can lead to your virtual machine in Azure being impacted: unplanned hardware maintenance, unexpected downtime, and planned maintenance. Unplanned Hardware Maintenance  event occurs when the Azure platform predicts that the hardware or any platform component associated to a physical machine, is about to fail. When the platform predicts a failure, it will issue an unplanned hardware maintenance event. Azure uses Live Migration technology to migrate the Virtual Machines from the failing hardware to a healthy physical machine. Live Migration is a VM preserving operation that only pauses the Virtual Machine for a short time, but performance might be reduced before and/or after the event. Unexpected Downtime  is when the hardware or the physical infrastructure for the virtual machine fails unexpectedly. Unexpected downtime can include local network failures, local disk failures, or other rack level failures. Whe...

  Introduction Azure Virtual Machines is one of several types of on-demand, scalable computing resources that Azure offers. Typically, you'll choose a virtual machine if you need more control over the computing environment than the choices such as App Service or Cloud Services offer. Azure Virtual Machines provide you with an operating system, storage, and networking capabilities and can run a wide range of applications. Virtual machines are part of the Infrastructure as a Service (IaaS) offering. IaaS is an instant computing infrastructure, provisioned and managed over the Internet. Quickly scale up and down with demand and pay only for what you use. Scenario Suppose you work for a company doing consumer research and you're responsible for managing the on-premises servers. The servers you administer run all the company infrastructure, from web servers to databases. However, the hardware is aging and starting to struggle to keep up with some of the new data analysis application...

  Attach Disks to VM Add a data disk in Windows/Linux Go to azure portal. In the menu on the left, click  Virtual Machines . Select the virtual machine from the list. On the virtual machine blade, click  Disks . On the  Disks  blade, click  + Add data disk . In the drop-down for the new disk, select  Create disk . In the  Create managed disk  blade, type in a name for the disk(Name should be similar to the name of the disk which is already present) and adjust the other settings as necessary. When you are done, click  Create . We can add only 1 TB disk at a time, if we want to add more TB's we have to add more number of disks. In the  Disks  blade, click save to save the new disk configuration for the VM. After Azure creates the disk and attaches it to the virtual machine, the new disk is listed in the v...

  Hello All, If you are using azure cloud in your environment so you have definitely faced issue where your VM got corrupted or due to some other issues you are unable to connect to it. This might be production or development machine and then it creates a big issue as you have some important data on that vm disks which you have not backed up. This issue mostly occurs when you make changes in fstab file or any boot file missing from your VM. Sometime there might be some other issues which are related to networking. So it’s always a good idea to check your network connection and basic troubleshooting before applying this solution. In this blog post we will go through the steps on how to create a new vm from existing vm’s disk snapshot. I have clearly mentioned the steps to create the snapshot of existing vm and how to create a new vm from created snapshot. Below steps will help you to create an azure vm from azure disk snapshot. Step 1: Create a snapshot First we have to create the s...
