Performance best practices for SQL Server in Azure Virtual Machines (link to resources)

How to create striped disk on azure (AKA Raid 0)

Disk Striping use multiple disks and stripe them together to get a combined higher IOPS and Throughput limit. Note that the combined limit per VM should be higher than the combined limits of attached premium disks.

You can check the maximum number of disks you can add to a virtual machine from here: Sizes for Windows virtual machines in Azure

1. Create “new disk” from powershell:

clear

# RM stands for resource manager, and is the new way of managing things in Azure

# you need to login the first time using this command
# Login-AzureRmAccount

$vm = Get-AzureRmVM -ResourceGroupName "md-test-stripe" -Name "md-test-stripe"

# adds 16 disks
for($i=1; $i -le 16; $i++) {
    $name = "md-test-stripe-disk{0:00}" -f $i
    $lun = $i - 1
    $vhdUri = "https://mdteststripedisks447.blob.core.windows.net/vhds/md-test-stripe-disk{0:00}.vhd" -f $i

    Write-Host "Add-AzureRmVMDataDisk -VM $vm -Name $name -DiskSizeInGB 16 -Lun $lun -Caching None -VhdUri $vhdUri -CreateOption Empty"

    $vm = Add-AzureRmVMDataDisk -VM $vm -Name $name -DiskSizeInGB 16 -Lun $lun -Caching None -VhdUri $vhdUri -CreateOption Empty
}

$vm.DataDiskNames

# uncomment when you are ready, this updates the VM on azure!
# Update-AzureRmVM -ResourceGroupName "md-test-stripe" -VM $vm

2. Create “new storage pool” from server manager with all the new disks you added

3. Create “new virtual disk” from powershell:

New-VirtualDisk -FriendlyName "sql-stripe" -StoragePoolFriendlyName "sql-stripe" -Interleave 65536 -NumberOfColumns 16 -ProvisioningType Fixed -ResiliencySettingName "Simple" -UseMaximumSize

4. Create “new volume” from server manager formatting in NTFS with allocation unit size set to 64KB

Software on the hosted build server

Took directly from visual studio site: Hosted build controller.

You can check the detail list, and install the visual studio extension “Avanade Extensions for VS2012” (VS2013 version) to track the software installed on the hosted build server using the Software Inventory functionality.

The hosted build server is deployed with the following software:

Windows Server 2012 R2, 64-bit environment, with Windows PowerShell
Team Foundation Build (Team Foundation Server 2013)

Azure Public IP Addresses

If you like me you’re interested to know the ip ranges that windows azure uses to connect to the internet 🙂 this is the right post 😉

Do not assume that traffic originating from these IP address ranges is trustworthy.

You can download Windows Azure Datacenter IP Ranges xml from the download center.

Here’s the list updated on 12th June 2014

How To Copy a Blob Across Storage Accounts and Regions

If you ever worked with Windows Azure, you’ve probably stumbled in the bad practice to let the control panel create the storage for you, with an unreadable and forgettable name, and with the worst thing you can do, leaving the storage outside an affinity group, that guarantee low latency between services and storage that should communicate each other.

It is possible with the Windows Azure PowerShell module to copy a storage blob across storage accounts and regions… asynchronously!

For example, you would need to move a virtual machine disk between storage account:

Import-Module Azure
Select-AzureSubscription "My Subscription Name"

$destContext = New-AzureStorageContext –StorageAccountName "MyStorageAccountName" -StorageAccountKey "MyStorageAccountKey"

$blob = Start-AzureStorageBlobCopy -SrcContainer vhds -SrcBlob "xxxx.vhd" -DestContainer vhds -DestBlob "xxxx.vhd" -DestContext $destContext

Then to check the status of the copying, you can execute this command:

$blob | Get-AzureStorageBlobCopyState

Getting Started with Windows Azure PowerShell

To start using Windows Azure PowerShell, you need to run just a couple of commands.

First import the windows azure powershell module:

Import-Module Azure

Retrieve all your subscriptions (certificate method, you should prefer to use the Azure AD method instead, see below):

Get-AzurePublishSettingsFile

A browser window opens at https://windows.azure.com/download/publishprofile.aspx, where you can sign in to Windows Azure and download the publish settings file.

Then import the subscription publish settings file:

Import-AzurePublishSettingsFile C:\MyDownloadedPublishProfile.publishsettings

You should delete the publishing profile that you downloaded after you import those settings. The downloaded profile contains a management certificate that should not be accessed by unauthorized users.

EDIT:

There’s a new way to login azure on powershell, without using the certificate method:

Use the Azure AD method (newest and preferred way)

Open the Azure PowerShell console, as instructed in How to: Install Azure PowerShell.
Type the following command:
Add-AzureAccount
In the window, type the email address and password associated with your account.
Azure authenticates and saves the credential information, and then closes the window.

Now you can make a lot of operations against the azure fabric (a lot more than you can do from the web portal), like getting the list of containers and the the list of the blobs of a container.

First you select the subscription you want to use:

Select-AzureSubscription -SubscriptionName "My Subscription Name"

Then you set the storage account you want to query on:

Set-AzureSubscription -SubscriptionName "My Subscription Name" -CurrentStorageAccount "mystorageaccount"

(to get the storage account name, you can run Get-AzureStorageAccount)

And now you can get the list of the containers:

Get-AzureStorageContainer

and the list of the blobs of a specified container:

Get-AzureStorageBlob -Container "containername"

How to use a Local Storage Resource

The Windows Azure Managed Library provides classes for accessing the local storage resource from within code that is running in a role instance.

You will just need to retrieve the full path of a named local storage, and then you can store any file you want. To retrieve the full path, you simple need this line of code:

RoleEnvironment.GetLocalResource("MainLocalStorage").RootPath

Create Local Storage on Cloud Services to store temporary files

On a cloud service, you can create a small local storage where you can save temporary files, yes I said temporary, because a local storage would not be guaranteed to be durable, for durable storage in Azure you should consider Azure SQL Database or Azure Storage (blob and tables). This reserved space could be useful to store custom error log files (nlog, log4net, …), for those files that are dynamically created by the application and you would like to cache it somewhere, and also for structured data files like database(sql ce, sqlite, …), but remember, just for volatile data.

You can create a local storage manually configuring the Service Definition configuration file, or through the visual studio user interface:

Open the Properties of the Web Role under the Cloud Service Project, go to Local Storage section, and click on “Add Local Storage”, name the storage, give a size, and save.

For more information about Local Storage Resources visit http://msdn.microsoft.com/en-us/library/windowsazure/ee758708.aspx

How to add a Windows Azure Cloud Service Project on an existing Web Project

You can accomplish this easy step just right-clicking on the Web Project and then select the menu entry “Add Windows Azure Cloud Service Project”

Adding a PaaS Cloud Service (Web, Woker Role) to a Virtual Network

A PaaS cloud service, web or worker role, can be added in a Virtual Network only by changing its service configuration file (ServiceConfiguration.Cloud.cscfg).

You need to add the NetworkConfiguration node just after the Role node as follow:

<?xml version="1.0" encoding="utf-16"?>
<ServiceConfiguration xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" serviceName="MyAzureApplication" osFamily="3" osVersion="*" schemaVersion="2013-03.2.0" xmlns="http://schemas.microsoft.com/ServiceHosting/2008/10/ServiceConfiguration">
    <Role name="MyMvcWebRole">
        <ConfigurationSettings>
            <Setting name="Microsoft.WindowsAzure.Plugins.Diagnostics.ConnectionString" value="DefaultEndpointsProtocol=https;AccountName=xxx;AccountKey=xxx" />
        </ConfigurationSettings>
        <Instances count="1" />
    </Role>
    <NetworkConfiguration>
        <VirtualNetworkSite name="myazure-vnet"/>
        <AddressAssignments>
            <InstanceAddress roleName="MyMvcWebRole">
                <Subnets>
                    <Subnet name="MainSubnet"/>
                </Subnets>
            </InstanceAddress>
        </AddressAssignments>
    </NetworkConfiguration>
</ServiceConfiguration>
