Azure Stack HCI is a cluster that requires a minimum of two servers.ĭespite the name, Azure Stack HCI is not all that similar to Azure Stack Hub, where users purchase Azure services to run on pre-approved hardware in their own data centre. ![]() That does not include any licensing costs for guest operating systems or other applications. Windows Server 2022 looks much like Windows 10 all the interesting changes are in core plumbing featuresĪzure Stack HCI is a hybrid virtualization platform where the customer buys validated hardware (though there is an option for installing on any compatible hardware) from an approved supplier, connects it to Azure, and pays $10 per physical core per month for running it. Limitations of SAC include only 18 months of support per release, a requirement for Software Assurance (a more expensive subscription license), and no desktop experience option. The purpose of SAC is for container workloads (host or container image) or scenarios where a VM is short-lived and easily replaced. In the old Windows Server world, users could choose between the Long Term Servicing Channel (LTSC) and Semi-Annual Channel (SAC) for installations, with LTSC being essentially the traditional model of a big release every two or three years, and SAC being more the "as-a-service" model with frequent feature updates to get the latest technology.īusinesses installing Windows Server for general-purpose use would normally use LTSC, which has five years of mainstream support and five years of extended support. Microsoft will not support a semi-annual release channel in the forthcoming Windows Server 2022, and users requiring frequent updates will be directed towards Azure Stack HCI (Hyperconverged Infrastructure). ![]()
