Over the past few months I have been hosting a free 1 hour Azure webcast to help educate U.S. government employees on the features and functionality available in the Microsoft Azure cloud. Past events included an overview of the Microsoft Enterprise Mobility suite and Azure Disaster Recovery Solutions. Going forward I am working with Azure specialists across the U.S. to provide more great webcast events. Below are two of the upcoming events currently scheduled:

Disaster Recovery Solutions
I am currently in the planning stages for future webcasts. Below are a few ideas I have, however, if you have any additional thoughts for content, please reach out to me using the contact link located on the SLG Events website.
- Azure Media Services
- Azure Site Recovery deep dive
- Hybrid Datacenter
With the release of Windows Server 2012 and Windows 8.0 a new storage technology was made available called Storage Spaces. This technology enables a virtualized storage platform that can group standard disks into storage pools. By using the capacity in the pool, one or more virtual drives called storage spaces can be created. Storage Spaces can provide many features such as resiliency, storage tiers, write-back cache and continuous availability.
By utilizing Storage Spaces in a Windows Server 2012 (or higher) VM hosted in Azure you can overcome some of the perceived limitations of Azure storage. Virtual hard drives (VHD) are stored in Microsoft Azure storage as page blobs which have a maximum size of 1TB. For basic tier virtual machines you can expect storage performance of 300 IOPS per VHD. For standard tier virtual machines the storage performance increases to 500 IOPS per VHD. If you take these limitations at face value it would appear that there may be some workloads that could not be deployed in an Azure virtual machine. One such example would be a SQL data warehouse.
I mentioned that these are perceived limitations and this is because there are ways to combine VHDs with Storage Spaces to provide higher IOPS and more capacity. The total number of VHDs that a single Windows Azure virtual machine can attach is determined by the size of the virtual machine. For example, a standard tier A3 (large) virtual machine can have up to 8 persistent 1TB data VHDs. All virtual machines have a 127GB disk configured for the operating system.
With Storage Spaces we can combine all of the virtual machine data disks into a single virtual drive where data is striped across all disks. This configuration does take a little bit of storage overhead, so although in our A3 example we could have up to 8TB of storage, the actual usable amount will be slightly less. This striping process can also increase our IOPS from 500 for a single disk to a maximum of (8*500) or 4,000 IOPS for the A3 virtual machine. Actual performance will vary depending on the Storage Space configuration and workloads running on the virtual drive.
For maximum performance it is recommended:
- Ensure that resiliency is not configured for the Storage Space virtual drive
- Configure the number of columns for Storage Space equal to the number of drives (VHDs) in the pool
- Configure the interleave value at least as large as the I/Os of your workload. I/Os that exceed the interleave are split into multiple stripes, which require multiple writes. For details on this I recommend reading the Block Size and Interleave section of this article on designing Storage Spaces for performance.
In the Script Gallery hosted by Microsoft there is a demonstration PowerShell script that shows how to build out a Microsoft Azure virtual machine using Storage Spaces. This script will build out a new virtual machine with the maximum number of data disks based on a select virtual machine size. Once the virtual machine is built, a remote PowerShell script is started that configures Storage Spaces to provide the highest storage performance currently available for that VM size.
I recommend reviewing the script and performing your own performance tests. By properly configuring Storage Spaces on the right sized VM you can achieve very high IOPS while also providing up to approximately 64TB of storage (based on standard G5 VM).

Recently Microsoft announced two new datacenters that are dedicated to U.S. government customers only. This includes Federal, State, Local, and Tribal governments and their solution providers. Benefits of this Government Community Cloud are:
- Physically isolated datacenter and network
- Data, applications, and hardware reside in the continental United States
- Provides true geographic redundancy with datacenters located more than 500 miles apart
- Operated by screen U.S. persons
- Committed to meeting rigorous compliance requirements and government policies
To learn more about the Microsoft Azure Government cloud check out the latest information on the Microsoft Azure Government website.
Since the Azure Government cloud is physically isolated, there are a few additional steps that must be completed in order to connect with Microsoft Azure PowerShell:
- add-AzureEnvironment -name “AzureGovernment” -PublishSettingsFileUrl “https://manage.windowsazure.us/publishsettings/index?client=xplat” -serviceendpoint “https://management.core.usgovcloudapi.net” -managementportalurl “http://manage.windowsazure.us” -StorageEndpoint “core.usgovcloudapi.net”
- Set-AzureEnvironment “AzureGovernment”
Once the PowerShell environment has been setup the next step is to use the Import-AzurePublishSettingsFile cmdlet to import the settings file you saved in the first step. After the PublishSettings file has been imported you can use the standard Azure PowerShell cmdlets to manage your Microsoft Azure Government subscription.
If you need to revert back to the Microsoft Azure public cloud you can use the command Remove-AzureEnvironment “AzureGovernment” in Microsoft Azure PowerShell.
When making system changes to a Windows virtual machine running in Azure it is possible to accidentally block RDP access. This could happen in a number of ways:
- Making changes to Windows Firewall
- Changes made to the registry
- Turning off Remote Desktop
To regain RDP connectivity to your virtual machine you can use the PowerShell Set-AzureVMAccessExtension cmdlet. Below is a sample script that shows how to use the cmdlet. Replace the VM name and the cloud service name with the appropriate values for your environment.
Get-AzureVM –Name MyVM –ServiceName MyVMService |Set-AzureVMAccessExtension | Update-AzureVM
Once you have run the script, use the Azure Management portal to reboot the virtual machine. Once it has restarted you should be able to use Remote Desktop to connect.

It is never a question of if an outage or disaster will strike your datacenter, but instead when will it occur and will you be prepared. In 2014 the Disaster Recovery Preparedness Council released their annual report on their Disaster Recovery Preparedness Benchmark Survey. This reported provided a very scary statistic that nearly 3 out of every 4 organizations that participated in the survey are at risk of failing to recover from a disaster or an outage. The study also indicated that “More than 60% of those who took the survey do not have a fully documented DR plan and another 40% admitted that the DR plan they current have did not prove very useful when it was called on to respond to their worst disaster recovery event or scenario.”
To address some of these concerns I have created a webcast video that outlines some of the possible solutions to enable organizations to meet their disaster recovery objectives. You can view this webcast on YouTube using the link below:
Disaster Recovery Solutions
This webcast provides a general overview of cloud based Disaster Recovery solutions including:
- Microsoft Azure Backup
- Microsoft Azure Site Recovery
- Microsoft StorSimple
Microsoft also has a great series of videos related to Microsoft Business Continuity solutions available on the Microsoft Virtual Academy website.
Earlier this month I did a one hour webcast for the Microsoft’s Enterprise Mobility Suite which you can now view using the link below. The suite is a collection of three products offered at a very affordable price: Microsoft Intune, Microsoft Azure Active Directory Premium, and Microsoft Azure Rights Management service. The Enterprise Mobility Suite enables organizations to manage devices, protect data, and empower users through self service identity features.
