Properties

BalancingMode

public string BalancingMode { get; set; }

Specifies how to determine whether the backend of a load balancer can handle additional traffic or is fully loaded. For usage guidelines, see Connection balancing mode. Backends must use compatible balancing modes. For more information, see Supported balancing modes and target capacity settings and Restrictions and guidance for instance groups. Note: Currently, if you use the API to configure incompatible balancing modes, the configuration might be accepted even though it has no impact and is ignored. Specifically, Backend.maxUtilization is ignored when Backend.balancingMode is RATE. In the future, this incompatible combination will be rejected. Check the BalancingMode enum for the list of possible values.

Property Value
Type	Description
`string`

CapacityScaler

public float CapacityScaler { get; set; }

A multiplier applied to the backend's target capacity of its balancing mode. The default value is 1, which means the group serves up to 100% of its configured capacity (depending on balancingMode). A setting of 0 means the group is completely drained, offering 0% of its available capacity. The valid ranges are 0.0 and [0.1,1.0]. You cannot configure a setting larger than 0 and smaller than 0.1. You cannot configure a setting of 0 when there is only one backend attached to the backend service. Not available with backends that don't support using a balancingMode. This includes backends such as global internet NEGs, regional serverless NEGs, and PSC NEGs.

Property Value
Type	Description
`float`

Description

public string Description { get; set; }

An optional description of this resource. Provide this property when you create the resource.

Property Value
Type	Description
`string`

Failover

public bool Failover { get; set; }

This field designates whether this is a failover backend. More than one failover backend can be configured for a given BackendService.

Property Value
Type	Description
`bool`

Group

public string Group { get; set; }

The fully-qualified URL of an instance group or network endpoint group (NEG) resource. To determine what types of backends a load balancer supports, see the Backend services overview. You must use the fully-qualified URL (starting with https://www.googleapis.com/) to specify the instance group or NEG. Partial URLs are not supported.
