2. Virtual Machine A virtual machine in Windows Azure is a server in the cloud that one can control and manage. After a virtual machine is created in Windows Azure, you can delete and re-create it whenever you need to. It can be accessed just like any other server. Virtual hard disks (.vhd files) are used to create a virtual machine. You can use the following types of virtual hard disks to create a virtual machine

3. Virtual Machine Image - An image is a template that you use to create a new virtual machine. An image doesn’t have specific settings like a running virtual machine, such as the computer name and user account settings. If you use an image to create a virtual machine, an operating system disk is automatically created for the new virtual machine.

4. Virtual Machine Disk - A disk is a VHD that you can boot and mount as a running version of an operating system. After an image is provisioned, it becomes a disk. A disk is always created when you use an image to create a virtual machine. Any VHD that is attached to virtualized hardware and that is running as part of a service is a disk.

5. Virtual Machine You can use the following options to create a virtual machine from an image: Create a virtual machine by using a platform image available from the Windows Azure Management Portal. Create and upload a.vhd file that contains an image to Windows Azure, and then use the uploaded image to create a virtual machine.

6. Virtual Machine Each virtual machine resides in a cloud service, either by itself, or grouped with other virtual machines. You can place virtual machines in the same cloud service to enable the virtual machines to communicate with each other, to load-balance network traffic among virtual machines, and to maintain high availability of the machines.

7. Virtual Machine How to create the virtual machine One can create a virtual machine From Gallery method in the Management Portal to create a custom virtual machine. This method provides more options than the Quick Create method does for configuring the virtual machine when you create it, such as the connected resources, the DNS name, and the network connectivity if needed.

8. Virtual Machine 1.Sign in to the Windows Azure Management Portal. 2.On the command bar, click New. 3.Click Virtual Machine, and then click From Gallery. 4.Click Platform Images, select one of the images, and then click the arrow to continue.

For this virtual machine, type MyTestVM1. 7.In Size, select the size of the virtual machine. The size you should select depends on the number of cores required to run your application. For this virtual machine, choose the smallest available size.

10. Virtual Machine 8.In New User Name, type a name for the administrative account that you want to use to manage the server. For this virtual machine, type MyTestVM1Admin. 9.In New Password, type a strong password for the administrative account on the virtual machine. In Confirm Password, retype the password. 10.Click the arrow to continue.

11. Virtual Machine 1.You can place virtual machines together under a cloud service to provide robust applications, but for this tutorial, you only create a single virtual machine. To do this, select Create a new cloud service. 2.In Cloud Service DNS Name, type a name that uses between 3 and 24 lowercase letters and numbers. This name becomes part of the URI that is used to contact the virtual machine through the cloud service. For this virtual machine, type MyService1.

12. Virtual Machine 3.In Region/Affinity Group/Virtual Network, select where you want to locate the virtual machine. 4.You can select a storage account where the VHD file is stored. For this tutorial, accept the default setting of Use an Automatically Generated Storage Account. 5.Under Availability Set, for the purposes of this tutorial use the default setting of None.

13. Virtual Machine 6.Click the arrow to continue. 7.Under Endpoints, new endpoints are created to allow connections for Remote Desktop and Windows PowerShell remoting. (Endpoints allow resources on the Internet or other virtual networks to communicate with a virtual machine.) You can add more endpoints now, or create them later. 8.Click the check mark to create the virtual machine.

14. Virtual Machine After the virtual machine and cloud service are created, the Management Portal lists the new virtual machine under Virtual Machines and lists the cloud service under Cloud Services. Both the virtual machine and the cloud service are started automatically.
