VMs are eligible to receive infrastructure and hypervisor updates as they become available. This may result in more maintenance operations (live migrations or terminations) for the VM than the PERIODIC and RECURRENT options.
Recurrent
VMs receive infrastructure and hypervisor updates on a periodic basis, minimizing the number of maintenance operations (live migrations or terminations) on an individual VM. This may mean a VM will take longer to receive an update than if it was configured for AS_NEEDED. Security updates will still be applied as soon as they are available. RECURRENT is used for GEN3 and Slice of Hardware VMs.
UndefinedMaintenanceInterval
A value indicating that the enum field is not set.
