Attributes
Name	Description
target_shape	str The distribution shape to which the group converges either proactively or on resize events (depending on the value set in updatePolicy.instanceRedistributionType). Check the TargetShape enum for the list of possible values. This field is a member of oneof_ _target_shape.
zones	MutableSequence[google.cloud.compute_v1.types.DistributionPolicyZoneConfiguration] Zones where the regional managed instance group will create and manage its instances.

Classes

TargetShape

TargetShape(value)

The distribution shape to which the group converges either proactively or on resize events (depending on the value set in updatePolicy.instanceRedistributionType).

Values: UNDEFINED_TARGET_SHAPE (0): A value indicating that the enum field is not set. ANY (64972): The group picks zones for creating VM instances to fulfill the requested number of VMs within present resource constraints and to maximize utilization of unused zonal reservations. Recommended for batch workloads that do not require high availability. ANY_SINGLE_ZONE (61100880): The group creates all VM instances within a single zone. The zone is selected based on the present resource constraints and to maximize utilization of unused zonal reservations. Recommended for batch workloads with heavy interprocess communication. BALANCED (468409608): The group prioritizes acquisition of resources, scheduling VMs in zones where resources are available while distributing VMs as evenly as possible across selected zones to minimize the impact of zonal failure. Recommended for highly available serving workloads. EVEN (2140442): The group schedules VM instance creation and deletion to achieve and maintain an even number of managed instances across the selected zones. The distribution is even when the number of managed instances does not differ by more than 1 between any two zones. Recommended for highly available serving workloads.
