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.
Impact of this Retirement Notice
On September 1, 2023, the IaaS VMs (Classic) will be fully retired and any active or allocated VMs will be suspended and deallocated. Customers will no longer be able to start IaaS VMs by using ASM. Any that are still running or allocated will be stopped and deallocated. Businesses should prioritize completing this migration as soon as possible to prevent business impact and to take advantage of the improved performance, security, and new features of Azure Resource Manager.
Please note: Microsoft is not deprecating the existing classic APIs, Cloud Services and resource model.
