description: |-
A multiplier applied to the group's maximum servicing capacity
(based on UTILIZATION, RATE or CONNECTION).
Default value is 1, which means the group will serve up to 100%

setting of 0 means the group is completely drained, offering
0% of its available Capacity. Valid range is [0.0,1.0].

group:

Reference to a ComputeInstanceGroup or ComputeNetworkEndpointGroup
resource. In case of instance group this defines the list of
instances that serve traffic. Member virtual machine instances from
each instance group must live in the same zone as the instance
group itself. No two backends in a backend service are allowed to
use same Instance Group resource.
For Network Endpoint Groups this defines list of endpoints. All
endpoints of Network Endpoint Group must be hosted on instances
located in the same zone as the Network Endpoint Group.
Backend services cannot mix Instance Group and Network Endpoint
Group backends.
When the 'load_balancing_scheme' is INTERNAL, only instance groups
are supported.

failoverPolicy:
description: Policy for failovers.
properties:
disableConnectionDrainOnFailover:
description: |-
On failover or failback, this field indicates whether connection drain
will be honored. Setting this to true has the following effect: connections
to the old active pool are not drained. Connections to the new active pool
use the timeout of 10 min (currently fixed). Setting to false has the
following effect: both old and new connections will have a drain timeout
of 10 min.
This can be set to true only if the protocol is TCP.
The default is false.
type: boolean
dropTrafficIfUnhealthy:
description: |-
This option is used only when no healthy VMs are detected in the primary
and backup instance groups. When set to true, traffic is dropped. When
set to false, new connections are sent across all VMs in the primary group.
The default is false.
type: boolean
failoverRatio:
description: |-
The value of the field must be in [0, 1]. If the ratio of the healthy
VMs in the primary backend is at or below this number, traffic arriving
at the load-balanced IP will be directed to the failover backend.
In case where 'failoverRatio' is not set or all the VMs in the backup
backend are unhealthy, the traffic will be directed back to the primary
backend in the "force" mode, where traffic will be spread to the healthy
VMs with the best effort, or to all VMs when no VM is healthy.
This field is only used with l4 load balancing.

type: string
localityLbPolicy:
description: |-
The load balancing algorithm used within the scope of the locality.
The possible values are -
* ROUND_ROBIN - This is a simple policy in which each healthy backend
is selected in round robin order.
* LEAST_REQUEST - An O(1) algorithm which selects two random healthy
hosts and picks the host which has fewer active requests.
* RING_HASH - The ring/modulo hash load balancer implements consistent
hashing to backends. The algorithm has the property that the
addition/removal of a host from a set of N hosts only affects
1/N of the requests.
* RANDOM - The load balancer selects a random healthy host.
* ORIGINAL_DESTINATION - Backend host is selected based on the client
connection metadata, i.e., connections are opened
to the same address as the destination address of
the incoming connection before the connection
was redirected to the load balancer.
* MAGLEV - used as a drop in replacement for the ring hash load balancer.
Maglev is not as stable as ring hash but has faster table lookup
build times and host selection times. For more information about
Maglev, refer to https://ai.google/research/pubs/pub44824
