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

Virtual Machine Image - An image is a template that you use to create a new virtual machine. An image doesnt 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.

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.

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.

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.

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.

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.

Virtual Machine 5.If multiple versions of the image are available, in Version Release Date, pick the version you want to use. 6.In Virtual Machine Name, type the name that you want to use for the virtual machine. 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.

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.

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.

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.

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.

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.

6.In the password box, type the user name and password that you specified when you created the virtual machine, and then click OK. 7.Click Yes to verify the identity of the virtual machine.

Virtual Machine

You can now work with the virtual machine just like you would a server in your office.

Virtual Machine How to attach a data disk to the new virtual machine Your application might need to store data. To set this up, attach a data disk to the virtual machine. The easiest way to do this is to attach an empty data disk to the virtual machine.

Virtual Machine 1.Sign in to the Windows Azure Management Portal. 2.Click Virtual Machines, and then select the MyTestVM1 virtual machine. 3.On the command bar, click Attach, and then click Attach Empty Disk.

Virtual Machine The Attach Empty Disk dialog box appears.

Virtual Machine 4.The Virtual Machine Name, Storage Location, File Name, and Host Cache Preference are already defined for you. All you have to do is enter the size that you want for the disk. Type 5 in the Size field. Note: All disks are created from a VHD file in Windows Azure storage. You can provide a name for the VHD file that is added to storage, but Windows Azure generates the name of the disk automatically.

Virtual Machine 5.Click the check mark to attach the data disk to the virtual machine. 6.Click the name of the virtual machine. This displays the dashboard so you can verify that the data disk was successfully attached to the virtual machine. The virtual machine now has 2 disks. The disk that you attached is listed in the Disks table.

Virtual Machine

After you attach the data disk to the virtual machine, the disk is offline and not initialized. Before you can use it to store data, you'll need to log on to the virtual machine and initialize the disk.

Virtual Machine 1.Connect to the virtual machine by using the steps in the previous section, How to log on to the virtual machine after you create it. 2.After you log on to the virtual machine, open Server Manager. In the left pane, expand Storage, and then click Disk Management.

3.Right-click Disk 2, and then click Initialize Disk.

4.Click OK to start the initialization process. 5.Right-click the space allocation area for Disk 2, click New Simple Volume, and then finish the wizard with the default values.

The disk is now online and ready to use with a new drive letter.

Configuration steps to connect to the virtual machine Using SSMS on another computer Create a TCP endpoint for the virtual machine. The virtual machine must have an endpoint to listen for incoming TCP communication. This Windows Azure configuration step, directs incoming TCP port traffic to a TCP port that is accessible to the virtual machine. 1. On the Windows Azure Management Portal, click on VIRTUAL MACHINES. 2. Click on your newly created virtual machine. Information about your virtual machine is presented. 3. Near the top of the page, select the ENDPOINTS page, and then at the bottom of the page, click ADD.

Configuration steps to connect to the virtual machine Using SSMS on another computer The SQL Server Database Engine cannot use Windows Authentication without domain environment. To connect to the Database Engine from another computer, configure SQL Server for mixed mode authentication. Mixed mode authentication allows both SQL Server Authentication and Windows Authentication. (Configuring mixed mode authentication might not be necessary if you have configured a Windows Azure Virtual Network.

Configuration steps to connect to the virtual machine Using SSMS on another computer While connected to the virtual machine by using Remote Desktop, on the Start menu, click All Programs, clickMicrosoft SQL Server version, and then click SQL Server Management Studio.

The first time you open Management Studio it must create the users Management Studio environment. This may take a few moments. When opening, Management Studio presents the Connect to Server dialog box. In the Server name box, type the name of the virtual machine to connect to the Database Engine with the Object Explorer. (Instead of the virtual machine name you can also use (local) or a single period as the Server name. Select Windows Authentication, and leaveyourVMname\yourlocaladministrator in the User name box. Click Connect.

Configuration steps to connect to the virtual machine Using SSMS on another computer Create SQL Server authentication logins To connect to the Database Engine from another computer, you must create at least one SQL Server authentication login. In SQL Server Management Studio Object Explorer, expand the folder of the server instance in which you want to create the new login. Right-click the Security folder, point to New, and select Login.

Configuration steps to connect to the virtual machine Using SSMS on another computer In the Login New dialog box, on the General page, enter the name of the new user in the Login name box. Select SQL Server authentication. In the Password box, enter a password for the new user. Enter that password again into the Confirm Password box. To enforce password policy options for complexity and enforcement, select Enforce password policy (recommended). This is a default option when SQL Server authentication is selected.

Configuration steps to connect to the virtual machine Using SSMS on another computer To enforce password policy options for expiration, select Enforce password expiration (recommended). Enforce password policy must be selected to enable this checkbox. This is a default option when SQL Server authentication is selected. To force the user to create a new password after the first time the login is used, select User must change password at next login (Recommended if this login is for someone else to use. If the login is for your own use, do not select this option.) Enforce password expiration must be selected to enable this checkbox. This is a default option when SQL Server authentication is selected.

Configuration steps to connect to the virtual machine Using SSMS on another computer From the Default database list, select a default database for the login. master is the default for this option. If you have not yet created a user database, leave this set to master. In the Default language list, leave default as the value.

If this is the first login you are creating, you may want to designate this login as a SQL Server administrator. If so, on theServer Roles page, check sysadmin. Security Note: Members of the sysadmin fixed server role have complete control of the Database Engine. You should carefully restrict membership in this role.

Click OK.

Configuration steps to connect to the virtual machine Using SSMS on another computer Determine the DNS name of the virtual machine To connect to the SQL Server Database Engine from another computer, you must know the Domain Name System (DNS) name of the virtual machine. (This is the name the internet uses to identify the virtual machine. You can use the IP address, but the IP address might change when Windows Azure moves resources for redundancy or maintenance. The DNS name will be stable because it can be redirected to a new IP address.)

Configuration steps to connect to the virtual machine Using SSMS on another computer In the Windows Azure Management Portal (or from the previous step), select VIRTUAL MACHINES. On the VIRTUAL MACHINE INSTANCES page, in the DNS NAME column, find and copy the DNS name for the virtual machine which appears preceded by http://. (The user interface might not display the entire name, but you can right-click on it, and select copy.)

Connect to the Database Engine from another computer On a computer connected to the internet, open SQL Server Management Studio. In the Connect to Server or Connect to Database Engine dialog box, in the Server name box, enter the DNS name of the virtual machine (determined in the previous task) and a public endpoint port number in the format ofDNSName,portnumber such as tutorialtestVM.cloudapp.net,57500.
