Microsoft has announced a series of developments for Azure Local, the platform that lets you run native Azure services from your own datacenter, your partner's datacenter, or the edge.
Azure Local is the new name given to Azure Stack HCI (Hyper-Converged Infrastructure). It's arguably one of the best Hybrid Cloud platforms currently available on the market. At its core is the Windows Server-based Azure Stack HCI operating system running Hyper-V hypervisor and Storage Spaces Direct and Azure Arc which combined work together to turn any supported infrastructure cluster into your own, private Azure cloud.
While Azure Local does not support multi-tenancy and a lot of its features are aimed towards large enterprise customers requiring data sovereignty or compute at the edge, it is often overlooked by service providers who can take advantage of Azure Local to enhance the functionality of their services, especially considering the most recently announced updates to Azure Local.
1. Microsoft 365 Local
Azure Local now enables you to run the core products of Microsoft’s collaboration suite Microsoft 365 out of your own datacenter on hardware owned and managed by you. At the time of writing, Microsoft 365 Local includes support for Exchange Server, SharePoint Server and Skype for Business Server.
2. Enhanced resiliency with rack aware cluster
This functionality allows you to convert two Azure Local clusters, running from separate racks, into local availability zones for fault tolerance and high availability. If one rack experiences a rack-level failure (e.g. a top-of-rack (ToR) switch failure or building power outage), the remaining rack continues to operate, maintaining data integrity and accessibility for all virtual machines (VMs) and containers that an outage that would take out.
3. Increased scale of Azure Local clusters
As a preview feature, Azure Local can scale to 100+ nodes, allowing you to run Azure Local at scale. Microsoft currently offers multi-rack deployments in preview for qualified opportunities. While it appears that multi-rack deployments of Azure Local are delivered as several pre-integrated racks of hardware and you can think of it more like an Azure Stack Hub deployment than Azure Stack HCI, this still is a significant step up in terms of scale as previously, Azure Local was limited to a maximum of 16 nodes.
4. Support for external SAN storage
Microsoft has announced support for external Storage Arrays from most A-brand Storage vendors. This will enable Service providers, utilizing Storage Arrays to deliver block storage, to continue using those arrays and leverage that investment. This can be a very significant improvement considering that Storage Arrays and their networking components can make up close to 40% of the total hardware investment per cluster.
Microsoft has confirmed that support for additional storage protocols and capabilities will be coming soon.
5. Disconnected operations for Azure Local
Disconnected operations will allow you to run your Azure Local deployment without a connection to the Azure public cloud. Running Azure Local in a disconnected mode will require a control plane to be deployed locally and thus increase the requirements for hardware running it which is a minor price to be paid for those requiring fully isolated environments for compliance, data sovereignty or other reasons.
This feature is in preview at the time of writing and is expected to be Generally Available this year.
6. Support for NVIDIA RTX PRO 6000 GPUs
The joint announcement from Microsoft and Nvidia focused on delivering NVIDIA RTX PRO 6000 Blackwell Server Edition GPU, a high-end, data center-class accelerator with massive compute power and memory. When combined with Azure Local, it enables you to run the most demanding AI, high-performance computing (HPC), and advanced graphics workloads right in your own data center or at the edge on Azure Local.
