class Google::Apis::ComputeV1::Backend

Message containing information of one individual backend.

Attributes

balancing_mode[RW]

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. Corresponds to the JSON property `balancingMode` @return [String]

capacity_scaler[RW]

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. Corresponds to the JSON property `capacityScaler` @return [Float]

description[RW]

An optional description of this resource. Provide this property when you create the resource. Corresponds to the JSON property `description` @return [String]

failover[RW]

This field designates whether this is a failover backend. More than one failover backend can be configured for a given BackendService. Corresponds to the JSON property `failover` @return [Boolean]

failover?[RW]

This field designates whether this is a failover backend. More than one failover backend can be configured for a given BackendService. Corresponds to the JSON property `failover` @return [Boolean]

group[RW]

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](cloud.google.com/load-balancing/docs/ backend-service#backends). You must use the fully-qualified URL (starting with www.googleapis.com/) to specify the instance group or NEG. Partial URLs are not supported. Corresponds to the JSON property `group` @return [String]

max_connections[RW]

Defines a target maximum number of simultaneous connections. For usage guidelines, see Connection balancing mode and Utilization balancing mode. Not available if the backend's balancingMode is RATE. Corresponds to the JSON property `maxConnections` @return [Fixnum]

max_connections_per_endpoint[RW]

Defines a target maximum number of simultaneous connections. For usage guidelines, see Connection balancing mode and Utilization balancing mode. Not available if the backend's balancingMode is RATE. Corresponds to the JSON property `maxConnectionsPerEndpoint` @return [Fixnum]

max_connections_per_instance[RW]

Defines a target maximum number of simultaneous connections. For usage guidelines, see Connection balancing mode and Utilization balancing mode. Not available if the backend's balancingMode is RATE. Corresponds to the JSON property `maxConnectionsPerInstance` @return [Fixnum]

max_rate[RW]

Defines a maximum number of HTTP requests per second (RPS). For usage guidelines, see Rate balancing mode and Utilization balancing mode. Not available if the backend's balancingMode is CONNECTION. Corresponds to the JSON property `maxRate` @return [Fixnum]

max_rate_per_endpoint[RW]

Defines a maximum target for requests per second (RPS). For usage guidelines, see Rate balancing mode and Utilization balancing mode. Not available if the backend's balancingMode is CONNECTION. Corresponds to the JSON property `maxRatePerEndpoint` @return [Float]

max_rate_per_instance[RW]

Defines a maximum target for requests per second (RPS). For usage guidelines, see Rate balancing mode and Utilization balancing mode. Not available if the backend's balancingMode is CONNECTION. Corresponds to the JSON property `maxRatePerInstance` @return [Float]

max_utilization[RW]

Optional parameter to define a target capacity for the UTILIZATION balancing mode. The valid range is [0.0, 1.0]. For usage guidelines, see Utilization balancing mode. Corresponds to the JSON property `maxUtilization` @return [Float]
