azure reserved instances

Azure Reserved Instances are a billing and capacity planning tool for Microsoft Azure that lets customers commit to one- or three-year terms on virtual machine (VM) usage in exchange for discounted rates. Recent discussions on WindowsForum highlight that Microsoft will stop new purchases and renewals of Azure Reserved VM Instances for selected older VM series on July 1, 2026, with full retirement of those legacy sizes by 2028. This change affects one-year reservations for fourteen retiring VM families and one- and three-year reservations for four Dv3/Ev3-era series. The move is a signal for Windows shops and enterprise IT teams to plan migrations off aging hardware, as Azure uses the reservation system to phase out older SKUs. The tag covers billing changes, migration deadlines, and the practical impact on cloud-heavy organizations.
