Strategy for distributing VMs across zones in a region.
Values:
UNDEFINED_TARGET_SHAPE (0):
A value indicating that the enum field is not
set.
ANY (64972):
GCE 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):
GCE always selects a single zone for all the
VMs, optimizing for resource quotas, available
reservations and general capacity. Recommended
for batch workloads that cannot tollerate
distribution over multiple zones. This the
default shape in Bulk Insert and Capacity
Advisor APIs.
BALANCED (468409608):
GCE prioritizes acquisition of resources,
scheduling VMs in zones where resources are
available while distributing VMs as evenly as
possible across allowed zones to minimize the
impact of zonal failure. Recommended for highly
available serving workloads.
