Microsoft’s Azure Virtual Machine (Classic) is approaching its full retirement date of September 1, 2023. "Classic" in IaaS VMs refers to VMs managed by Azure Service Manager (ASM). While ASM has full IaaS capabilities and many enhancements over the years, the management of IaaS VMs through Azure Service Manager was deprecated by Microsoft in February 2020. ASM is the old control plane of Azure, responsible for creating, managing, and deleting VMs as well as performing other control plane operations. It’s estimated that 10% of IaaS VMs are still using Azure ASM. Those organizations need to start planning their migration today, given that full retirement is less than three months away.
