Microsoft Announces Availability of Azure Stack HCI Solutions

This week Microsoft announced that "Azure in a box" would be getting hyperconverged infrastructure (HCI) capabilities with its new Azure Stack HCI solutions.

HCI is typically described as a Windows Server capability, which first appeared with Windows Server 2016. Organizations can use it to run storage, compute and networking operations on a single server in a cluster. This arrangement also lets organizations use off-the-shelf, lower-cost components, including SATA and NVMe solid-state drives and persistent memory silicon, plus the Storage Spaces software-defined storage pools capability of Windows Server.

Azure Stack HCI solutions are yet another Azure Stack product offered by Microsoft and its hardware partners. They're aimed more toward organizations wanting to run applications on traditional virtual machine (VM) infrastructures "for efficiency and performance gains," according to an announcement by Julia White, corporate vice president of Microsoft Azure:

We are bringing our existing HCI technology into the Azure Stack family for customers to run virtualized applications on-premises with direct access to Azure management services such as backup and disaster recovery. Azure Stack HCI solutions feature the same software-defined compute, storage, and networking technology as the existing Azure Stack, and include simplified cloud access via the Azure hybrid services in Windows Admin Center.

To use Azure Stack HCI solutions, organizations must purchase "Microsoft-validated hardware" from Microsoft's partners. There are currently 15 partners with the HCI hardware offerings. Organizations will also need to use the Windows Server 2019 Datacenter edition.

The browser-based Windows Admin Center is the main management tool for Azure Stack HCI solutions. It'll hook into other Azure tools, such as Azure Monitor, Azure Security Center, Azure Update Management and Azure Site Recovery, among others. Microsoft has been adding capabilities to Windows Admin Center over the years and recently announced a preview of version 1903.

A Microsoft video on Azure Stack HCI solutions depicted them as a way for organizations to upgrade their infrastructures at a lower cost. Jeff Woolsey, a principal program manager at Microsoft for Windows Server, noted that organizations have been holding onto their servers longer, for 7.5 years, eight years and even 10 years. However, with 10-year-old servers, they don't have things like Secure Boot, Unified Extensible Firmware Interface (UEFI) and Trusted Platform Modules (TPMs) to take advantage of better security.

Some applications just need to run in on-premises environments and don't require many of Microsoft's Platform-as-a-Service (PaaS) offerings, which is another reason Microsoft came up with Azure Stack HCI solutions, according to Vijay Tewari, director of Azure Stack, in the video. Organizations can also use Azure Stack HCI solutions to avoid latency issues with their hosted applications, he added.

In the video, a "hybrid" overview slide (Figure 1) was shown.

Azure Stack HCI solutions users are conceived as being more interested hosting their own applications and just tapping Microsoft's cloud services for things like Azure Backup, Azure Site Recovery and Azure Monitor, according to the slide.

If an organization wanted to use the Infrastructure-as-a-Service and Paas solutions of Azure in their hybrid environments, then Microsoft's Azure Stack product is the option to use. Azure Stack is a collection of Microsoft's Azure datacenter technologies delivered in an appliance for organizations to deploy on their own infrastructures, or it's offered as a managed service by Microsoft's Cloud Solution Provider partners.

The upgrade path to Azure Stack for users of Azure Stack HCI solutions isn't a quick one. To make the switch, they'll have to move their data to Azure Stack.
