Windows Server Datacenter: Azure Edition isn’t a brand new model of Windows Server, however for Azure customers, it capabilities as one. It’s a picture and version of Windows Server that’s optimized to run on Azure, providing numerous new options that solely work for Azure customers.
SEE: The Essential Microsoft Azure Certification Bundle (TechRepublic Academy)
This Azure-friendly method to Windows Server has just lately acquired a number of updates and is anticipated to be additional optimized in 2023 and past. In this report, we’ll cowl the newest options of Windows Server Azure Edition and what you possibly can anticipate to see within the close to future.

What is Windows Server Azure Edition?
Microsoft Windows Server Datacenter: Azure Edition is among the three essential variations of Windows Server 2022. The different two variations have much less of an Azure lean — Windows Server 2022 Standard and Windows Server 2022 Datacenter. Azure Edition’s essential differentiators embrace the Azure Extended Network, hotpatching, SMB over QUIC and Storage Replica compression. Otherwise, it shares a number of similarities with Windows Server 2022 Datacenter.
Using Azure Edition doesn’t essentially imply you possibly can solely run it within the public cloud; as of October 2022, you may as well use it for digital machines on an Azure Stack HCI cluster by yourself infrastructure as a result of that {hardware} is specified and managed like Azure public cloud.
You nonetheless can’t put Azure Edition by yourself servers or run it in Hyper-V or different hypervisors. You can also’t run it in different clouds as a result of it’s optimized for Azure particularly.
Is Azure Edition often up to date?
Because it runs within the cloud, the place Microsoft can replace {hardware}, software program and companies sooner, Azure Edition will get new performance a lot ahead of the Long-Term Servicing Channel releases that come out each three years.
Microsoft is promising a brand new launch of Windows Server Azure Edition yearly, delivered by Windows Update fairly than as a brand new working system to which you would need to improve your VMs. You can consider this method because the alternative for the Semi-Annual Channel releases of Windows Server, which have been geared toward organizations that wished to maneuver extra shortly through the use of containers. Azure Stack HCI has taken over that function, and you may run Azure Edition there as properly.

Azure Edition new releases will attain normal availability within the fall of every yr, however you possibly can strive new options in VMs beginning within the spring as a part of The Windows Insider Program previews. If you select to preview earlier than the autumn launch cycle, Microsoft does warning that these options are nonetheless in growth, are usually not prepared for manufacturing workloads and are usually not assured to be included within the delivery model.
The present model is Windows Server 2022 Datacenter: Azure Edition, which now contains some options that have been in preview earlier in 2022. The present preview — Windows Server VNext Datacenter: Azure Edition — can have new options beginning in Spring 2023.
New options in Windows Server Azure Edition 2022
Hotpatching
When Microsoft patches the servers Azure runs on, it doesn’t have to attend for them to close down and reboot. Instead, it hotpatches them, which occurs shortly sufficient that they don’t even cease responding on the community.
This requires numerous management over the {hardware} and particularly the drivers. There are too many variables for hotpatching to work properly on the wide selection of server {hardware} used on-premises, however utilizing Azure Automanage, you possibly can apply safety patches to Azure Edition VMs with out rebooting.
This additionally works for Azure Stack HCI because it runs on validated {hardware}, so Microsoft can check with the combos of {hardware} and drivers that hotpatching must take care of. Currently, hotpatching works with VMs that use the Azure Edition Core picture.
Moving away from preview pictures
There are many enhancements to Azure Edition that don’t require you to make use of preview pictures for the subsequent launch. This is as a result of they both come from updates in different services or as a result of they’ve been added to the present Azure Edition by Windows Update.
Access to Azure networking options
Azure Edition VMs that use both Core or the Desktop expertise GUI can make the most of some Azure networking options like SMB over QUIC, which is the subsequent era of SMB with built-in compression and encryption. With this new function, customers can ensure that their cloud file shares are as safe as they might be on their very own networks.

SMB over QUIC now works on Azure Stack HCI in addition to in Azure, that means you possibly can transfer away from VPNs for supporting distant employees who use Windows 11, Windows Server 2022 or third-party purchasers for platforms like Android.
The QUIC consumer is constructed into Windows 11, so finish customers gained’t see any distinction, however their connection shall be in a TLS 1.3-encrypted tunnel over UDP port 443 fairly than TCP 445. The QUIC server is just out there in Windows Server 2022 Azure Edition.
SMB compression in Storage Replica
If you’re utilizing the Storage Replica function to copy volumes between servers or clusters for failover and catastrophe restoration, you may find yourself transferring giant quantities of information over lengthy distances, between knowledge facilities or to Azure. The September 2022 cumulative replace now permits Azure Edition customers to make use of SMB compression for asynchronous replication in Storage Replica, which is proving to dramatically pace up the file switch course of.
Windows Server Azure Edition: 2023 new options and past
Expanded hotpatching entry
Hotpatching is presently out there for VMs that use the Azure Edition Core picture, however the place it will be most helpful is with the Desktop expertise, since its further options just like the Explorer shell and Start menu make it extra more likely to want safety patches and updates.
The VNext Azure Edition previews which can be coming in spring 2023 will embrace hotpatching VMs with Desktop expertise; they gained’t must reboot for month-to-month safety updates. Although VMs will nonetheless need to restart just a few instances a yr to get a brand new baseline with a cumulative replace, Microsoft estimates that this alteration may take 12 reboots in a yr down to only 4 annual reboots.
Additional certificate-based safety
In Spring 2023, it is possible for you to so as to add further consumer certificates to safe SMB over QUIC. SMB over QUIC already makes use of certificates on the file server that the SMB consumer has to belief. However, this spring replace will allow you to require purchasers to deploy a certificates as properly earlier than they’ll join, including a further layer of safety to the method.
Easier methods to use SMB compression
Currently, there isn’t a lot documentation on organising SMB compression in Storage Replica. In the long run, customers will have the ability to use the Windows Admin Center GUI to configure it in the identical method you possibly can activate SMB compression for normal file shares. But, for now, you should use these PowerShell instructions to make use of the function.
How to maneuver to Windows Server Azure Edition in your non-public cloud
Swap licensed cores
If you need to transfer to Azure Stack HCI so you need to use Azure Edition VMs, however you’ve already paid for Windows Server Datacenter Software Assurance, Microsoft is waiving the standard host and subscription charges. This means you possibly can swap licensed cores to Azure Stack HCI with out paying something further and run limitless Windows Server visitor workloads. For Azure Edition, you should be utilizing Azure Stack HCI model 21H2 or 22H2 and have Azure Benefits enabled.
Use Azure Arc and Azure Marketplace
Use Azure Arc to deploy and handle VMs on Azure Stack HCI, and you may pull pictures, together with Azure Edition from the Azure Marketplace, to make use of for these VMs. You’ll want to make use of Arc-enabled administration Preview 2 for this. Azure Stack HCI defaults to utilizing Azure Edition pictures created by the Marketplace for brand spanking new VMs, so these pictures get the advantages of hotpatching and SMB over QUIC.
Download ISOs of Azure Edition
You also can obtain ISOs of Azure Edition for creating new VMs or upgrading an present VM in place on Azure Stack HCI. The obtain isn’t restricted in any method, so you possibly can experiment with working it in a VM on different {hardware} when you don’t but have Azure Stack HCI {hardware} out there; though, it’s not supported there. If you’re utilizing an ISO for Azure Edition, you’ll have to configure hotpatching your self fairly than utilizing Azure Automanage.
As with managing SMB compression for Storage Replica, this may increasingly get easier sooner or later, however since Windows Server Azure Edition is designed to present you extra of the advantages of Azure in your VMs, the Azure instruments will all the time be the best strategy to handle it.
Windows Server Azure Edition options
Although there are not any true options to Windows Server that combine seamlessly with the Azure atmosphere, a number of different working techniques and servers supply related options and capabilities to customers who don’t require Azure-specific performance.
In specific, open-source working techniques and servers are an amazing choice for customers who need further customizability and robust consumer help communities. These are among the greatest Windows Server Azure Edition options to contemplate:
- TrueNAS
- Ubuntu Linux
- SUSE Linux Enterprise Server
- Red Hat Enterprise Linux
