public Backend()

Method Detail

getBalancingMode

public String getBalancingMode()

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.

Returns:

value or null for none

setBalancingMode

public Backend setBalancingMode(String balancingMode)

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.

Parameters:

balancingMode - balancingMode or null for none

getCapacityScaler

public Float getCapacityScaler()

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.

Returns:

value or null for none

setCapacityScaler

public Backend setCapacityScaler(Float capacityScaler)

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.

Parameters:

capacityScaler - capacityScaler or null for none

getDescription

public String getDescription()

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

Returns:

value or null for none

setDescription

public Backend setDescription(String description)

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

Parameters:

description - description or null for none

getFailover

public Boolean getFailover()

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

Returns:

value or null for none

setFailover

public Backend setFailover(Boolean failover)

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

Parameters:

failover - failover or null for none

getGroup

public String getGroup()

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](https://cloud.google.com/load-balancing/docs/backend-service#backends). 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.

Returns:

value or null for none

setGroup

public Backend setGroup(String group)

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](https://cloud.google.com/load-balancing/docs/backend-service#backends). 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.
