HttpBackendGroup

An HTTP backend group resource.

Field	Description
backends[]	HttpBackend List of HTTP backends.
connection	ConnectionSessionAffinity Connection-based session affinity configuration. For now, a connection is defined only by an IP address of the client. Includes only one of the fields `connection`, `header`, `cookie`. Session affinity configuration for the backend group. For details about the concept, see documentation. If session affinity is configured, the backend group should contain exactly one active backend (i.e. with positive HttpBackend.backendWeight), its HttpBackend.backendType should be TargetGroupsBackend, and its [LoadBalancingConfig.load_balancing_mode] should be `MAGLEV_HASH`. If any of these conditions are not met, session affinity will not work.
header	HeaderSessionAffinity HTTP-header-field-based session affinity configuration. Includes only one of the fields `connection`, `header`, `cookie`. Session affinity configuration for the backend group. For details about the concept, see documentation. If session affinity is configured, the backend group should contain exactly one active backend (i.e. with positive HttpBackend.backendWeight), its HttpBackend.backendType should be TargetGroupsBackend, and its [LoadBalancingConfig.load_balancing_mode] should be `MAGLEV_HASH`. If any of these conditions are not met, session affinity will not work.
cookie	CookieSessionAffinity Cookie-based session affinity configuration. Includes only one of the fields `connection`, `header`, `cookie`. Session affinity configuration for the backend group. For details about the concept, see documentation. If session affinity is configured, the backend group should contain exactly one active backend (i.e. with positive HttpBackend.backendWeight), its HttpBackend.backendType should be TargetGroupsBackend, and its [LoadBalancingConfig.load_balancing_mode] should be `MAGLEV_HASH`. If any of these conditions are not met, session affinity will not work.

HttpBackend

An HTTP backend resource.

Field	Description
name	string Required field. Name of the backend.
backendWeight	google.protobuf.Int64Value Backend weight. Traffic is distributed between backends of a backend group according to their weights. Weights must be set either for all backends in a group or for none of them. Setting no weights is the same as setting equal non-zero weights for all backends. If the weight is non-positive, traffic is not sent to the backend.
loadBalancingConfig	LoadBalancingConfig Load balancing configuration for the backend.
port	int64 Port used by all targets to receive traffic.
targetGroups	TargetGroupsBackend Target groups that belong to the backend. For details about target groups, see documentation. Includes only one of the fields `targetGroups`, `storageBucket`. Reference to targets that belong to the backend. A backend may be a set of target groups or an Object Storage bucket. For details about backend types, see documentation.
storageBucket	StorageBucketBackend Object Storage bucket to use as the backend. For details about buckets, see documentation. If a bucket is used as a backend, the list of bucket objects and the objects themselves must be publicly accessible. For instructions, see documentation. Includes only one of the fields `targetGroups`, `storageBucket`. Reference to targets that belong to the backend. A backend may be a set of target groups or an Object Storage bucket. For details about backend types, see documentation.
healthchecks[]	HealthCheck Health checks to perform on targets from target groups. For details about health checking, see documentation. If no health checks are specified, active health checking is not performed.
tls	BackendTls Settings for TLS connections between load balancer nodes and backend targets. If specified, the load balancer establishes HTTPS (HTTP over TLS) connections with targets and compares received certificates with the one specified in BackendTls.validationContext. If not specified, the load balancer establishes unencrypted HTTP connections with targets.
useHttp2	bool Enables HTTP/2 usage in connections between load balancer nodes and backend targets. Default value: `false`, HTTP/1.1 is used.

LoadBalancingConfig

A load balancing configuration resource.

Field	Description
panicThreshold	int64 Threshold for panic mode. If percentage of healthy backends in the group drops below threshold, panic mode will be activated and traffic will be routed to all backends, regardless of their health check status. This helps to avoid overloading healthy backends. For details about panic mode, see documentation. If the value is `0`, panic mode will never be activated and traffic is routed only to healthy backends at all times. Default value: `0`.
localityAwareRoutingPercent	int64 Percentage of traffic that a load balancer node sends to healthy backends in its availability zone. The rest is divided equally between other zones. For details about zone-aware routing, see documentation. If there are no healthy backends in an availability zone, all the traffic is divided between other zones. If `strictLocality` is `true`, the specified value is ignored. A load balancer node sends all the traffic within its availability zone, regardless of backends' health. Default value: `0`.
strictLocality	bool Specifies whether a load balancer node should only send traffic to backends in its availability zone, regardless of their health, and ignore backends in other zones. If set to `true` and there are no healthy backends in the zone, the node in this zone will respond to incoming traffic with errors. For details about strict locality, see documentation. If `strict_locality` is `true`, the value specified in `localityAwareRoutingPercent` is ignored. Default value: `false`.
mode	enum LoadBalancingMode Load balancing mode for the backend. For details about load balancing modes, see documentation. `ROUND_ROBIN`: Round robin load balancing mode. All endpoints of the backend take their turns to receive requests attributed to the backend. `RANDOM`: Random load balancing mode. Default value. For a request attributed to the backend, an endpoint that receives it is picked at random. `LEAST_REQUEST`: Least request load balancing mode. To pick an endpoint that receives a request attributed to the backend, the power of two choices algorithm is used; that is, two endpoints are picked at random, and the request is sent to the one which has the fewest active requests. `MAGLEV_HASH`: Maglev hashing load balancing mode. Each endpoint is hashed, and a hash table with 65537 rows is filled accordingly, so that every endpoint occupies the same amount of rows. An attribute of each request is also hashed by the same function (if session affinity is enabled for the backend group, the attribute to hash is specified in session affinity configuration). The row with the same number as the resulting value is looked up in the table to determine the endpoint that receives the request. If the backend group with session affinity enabled contains more than one backend with positive weight, endpoints for backends with `MAGLEV_HASH` load balancing mode are picked at `RANDOM` instead.

TargetGroupsBackend

A resource for target groups that belong to the backend.

Field

Description

targetGroupIds[]

string

List of ID's of target groups that belong to the backend.

To get the ID's of all available target groups, make a TargetGroupService.List request.

StorageBucketBackend

A resource for Object Storage bucket used as a backend. For details about the concept,
see documentation.

Field

Description

bucket

string

Required field. Name of the bucket.

HealthCheck

A health check resource.
For details about the concept, see documentation.

Field	Description
timeout	google.protobuf.Duration Required field. Health check timeout. The timeout is the time allowed for the target to respond to a check. If the target doesn't respond in time, the check is considered failed.
interval	google.protobuf.Duration Required field. Base interval between consecutive health checks.
intervalJitterPercent	double
healthyThreshold	int64 Number of consecutive successful health checks required to mark an unhealthy target as healthy. Both `0` and `1` values amount to one successful check required. The value is ignored when a load balancer is initialized; a target is marked healthy after one successful check. Default value: `0`.
unhealthyThreshold	int64 Number of consecutive failed health checks required to mark a healthy target as unhealthy. Both `0` and `1` values amount to one unsuccessful check required. The value is ignored if a health check is failed due to an HTTP `503 Service Unavailable` response from the target (not applicable to TCP stream health checks). The target is immediately marked unhealthy. Default value: `0`.
healthcheckPort	int64 Port used for health checks. If not specified, the backend port (HttpBackend.port or GrpcBackend.port) is used for health checks.
stream	StreamHealthCheck TCP stream health check settings. Includes only one of the fields `stream`, `http`, `grpc`. Protocol-specific health check settings. The protocols of the backend and of its health check may differ, e.g. a gRPC health check may be specified for an HTTP backend.
http	HttpHealthCheck HTTP health check settings. Includes only one of the fields `stream`, `http`, `grpc`. Protocol-specific health check settings. The protocols of the backend and of its health check may differ, e.g. a gRPC health check may be specified for an HTTP backend.
grpc	GrpcHealthCheck gRPC health check settings. Includes only one of the fields `stream`, `http`, `grpc`. Protocol-specific health check settings. The protocols of the backend and of its health check may differ, e.g. a gRPC health check may be specified for an HTTP backend.
plaintext	PlaintextTransportSettings Includes only one of the fields `plaintext`, `tls`. Optional transport protocol for health checks.

If set to 0, session cookies are used, which are stored by clients in temporary memory and are deleted
on client restarts.

If not set, the balancer does not generate cookies and only uses incoming ones for establishing session affinity.

GrpcBackendGroup

A gRPC backend group resource.

Field	Description
backends[]	GrpcBackend List of gRPC backends.
connection	ConnectionSessionAffinity Connection-based session affinity configuration. For now, a connection is defined only by an IP address of the client. Includes only one of the fields `connection`, `header`, `cookie`. Session affinity configuration for the backend group. For details about the concept, see documentation. If session affinity is configured, the backend group should contain exactly one active backend (i.e. with positive GrpcBackend.backendWeight), and its [LoadBalancingConfig.load_balancing_mode] should be `MAGLEV_HASH`. If any of these conditions are not met, session affinity will not work.
header	HeaderSessionAffinity HTTP-header-field-based session affinity configuration. Includes only one of the fields `connection`, `header`, `cookie`. Session affinity configuration for the backend group. For details about the concept, see documentation. If session affinity is configured, the backend group should contain exactly one active backend (i.e. with positive GrpcBackend.backendWeight), and its [LoadBalancingConfig.load_balancing_mode] should be `MAGLEV_HASH`. If any of these conditions are not met, session affinity will not work.
cookie	CookieSessionAffinity Cookie-based session affinity configuration. Includes only one of the fields `connection`, `header`, `cookie`. Session affinity configuration for the backend group. For details about the concept, see documentation. If session affinity is configured, the backend group should contain exactly one active backend (i.e. with positive GrpcBackend.backendWeight), and its [LoadBalancingConfig.load_balancing_mode] should be `MAGLEV_HASH`. If any of these conditions are not met, session affinity will not work.

GrpcBackend

A gRPC backend resource.

Field	Description
name	string Required field. Name of the backend.
backendWeight	google.protobuf.Int64Value Backend weight. Traffic is distributed between backends of a backend group according to their weights. Weights must be set either for all backends of a group or for none of them. Setting no weights is the same as setting equal non-zero weights for all backends. If the weight is non-positive, traffic is not sent to the backend.
loadBalancingConfig	LoadBalancingConfig Load balancing configuration for the backend.
port	int64 Port used by all targets to receive traffic.
targetGroups	TargetGroupsBackend Target groups that belong to the backend. Includes only one of the fields `targetGroups`. Reference to targets that belong to the backend. For now, targets are referenced via target groups.
healthchecks[]	HealthCheck Health checks to perform on targets from target groups. For details about health checking, see documentation. If no health checks are specified, active health checking is not performed.
tls	BackendTls Settings for TLS connections between load balancer nodes and backend targets. If specified, the load balancer establishes HTTPS (HTTP over TLS) connections with targets and compares received certificates with the one specified in BackendTls.validationContext. If not specified, the load balancer establishes unencrypted HTTP connections with targets.

StreamBackendGroup

A stream (TCP) backend group resource.

Field

Description

backends[]

StreamBackend

List of stream (TCP) backends.

connection

ConnectionSessionAffinity

Connection-based session affinity configuration.

For now, a connection is defined only by an IP address of the client.

Includes only one of the fields connection.

Session affinity configuration for the backend group.

For details about the concept, see
documentation.

If session affinity is configured, the backend group should contain exactly one active backend (i.e. with positive
HttpBackend.backendWeight), its HttpBackend.backendType should be TargetGroupsBackend, and its
[LoadBalancingConfig.load_balancing_mode] should be MAGLEV_HASH. If any of these conditions are not met, session
affinity will not work.

StreamBackend

A stream (TCP) backend resource.

Field	Description
name	string Name of the backend.
backendWeight	google.protobuf.Int64Value Backend weight. Traffic is distributed between backends of a backend group according to their weights. Weights must be set either for all backends in a group or for none of them. Setting no weights is the same as setting equal non-zero weights for all backends. If the weight is non-positive, traffic is not sent to the backend.
loadBalancingConfig	LoadBalancingConfig Load balancing configuration for the backend.
port	int64 Port used by all targets to receive traffic.
targetGroups	TargetGroupsBackend Target groups that belong to the backend. For details about target groups, see documentation. Includes only one of the fields `targetGroups`. Reference to targets that belong to the backend.
healthchecks[]	HealthCheck Health checks to perform on targets from target groups. For details about health checking, see documentation. If no health checks are specified, active health checking is not performed.
tls	BackendTls Settings for TLS connections between load balancer nodes and backend targets. If specified, the load balancer establishes TLS-encrypted TCP connections with targets and compares received certificates with the one specified in BackendTls.validationContext. If not specified, the load balancer establishes unencrypted TCP connections with targets.
enableProxyProtocol	bool If set, proxy protocol will be enabled for this backend.

An Operation resource. For more information, see Operation.

Field	Description
id	string ID of the operation.
description	string Description of the operation. 0-256 characters long.
createdAt	google.protobuf.Timestamp Creation timestamp.
createdBy	string ID of the user or service account who initiated the operation.
modifiedAt	google.protobuf.Timestamp The time when the Operation resource was last modified.
done	bool If the value is `false`, it means the operation is still in progress. If `true`, the operation is completed, and either `error` or `response` is available.
metadata	CreateBackendGroupMetadata Service-specific metadata associated with the operation. It typically contains the ID of the target resource that the operation is performed on. Any method that returns a long-running operation should document the metadata type, if any.
error	google.rpc.Status The error result of the operation in case of failure or cancellation. Includes only one of the fields `error`, `response`. The operation result. If `done == false` and there was no failure detected, neither `error` nor `response` is set. If `done == false` and there was a failure detected, `error` is set. If `done == true`, exactly one of `error` or `response` is set.
response	BackendGroup The normal response of the operation in case of success. If the original method returns no data on success, such as Delete, the response is google.protobuf.Empty. If the original method is the standard Create/Update, the response should be the target resource of the operation. Any method that returns a long-running operation should document the response type, if any. Includes only one of the fields `error`, `response`. The operation result. If `done == false` and there was no failure detected, neither `error` nor `response` is set. If `done == false` and there was a failure detected, `error` is set. If `done == true`, exactly one of `error` or `response` is set.

stream	StreamBackendGroup List of stream (TCP) backends that the backend group consists of. Includes only one of the fields `http`, `grpc`, `stream`. Backends that the backend group consists of.
createdAt	google.protobuf.Timestamp Creation timestamp.

HttpBackendGroup

An HTTP backend group resource.

Field	Description
backends[]	HttpBackend List of HTTP backends.
connection	ConnectionSessionAffinity Connection-based session affinity configuration. For now, a connection is defined only by an IP address of the client. Includes only one of the fields `connection`, `header`, `cookie`. Session affinity configuration for the backend group. For details about the concept, see documentation.

If any of these conditions are not met, session affinity will not work.
header	HeaderSessionAffinity HTTP-header-field-based session affinity configuration. Includes only one of the fields `connection`, `header`, `cookie`. Session affinity configuration for the backend group. For details about the concept, see documentation. If session affinity is configured, the backend group should contain exactly one active backend (i.e. with positive HttpBackend.backendWeight), its HttpBackend.backendType should be TargetGroupsBackend, and its [LoadBalancingConfig.load_balancing_mode] should be `MAGLEV_HASH`. If any of these conditions are not met, session affinity will not work.
cookie	CookieSessionAffinity Cookie-based session affinity configuration. Includes only one of the fields `connection`, `header`, `cookie`. Session affinity configuration for the backend group. For details about the concept, see documentation. If session affinity is configured, the backend group should contain exactly one active backend (i.e. with positive HttpBackend.backendWeight), its HttpBackend.backendType should be TargetGroupsBackend, and its [LoadBalancingConfig.load_balancing_mode] should be `MAGLEV_HASH`. If any of these conditions are not met, session affinity will not work.

port	int64 Port used by all targets to receive traffic.
targetGroups	TargetGroupsBackend Target groups that belong to the backend. For details about target groups, see documentation. Includes only one of the fields `targetGroups`, `storageBucket`. Reference to targets that belong to the backend. A backend may be a set of target groups or an Object Storage bucket. For details about backend types, see documentation.
storageBucket	StorageBucketBackend Object Storage bucket to use as the backend. For details about buckets, see documentation. If a bucket is used as a backend, the list of bucket objects and the objects themselves must be publicly accessible. For instructions, see documentation. Includes only one of the fields `targetGroups`, `storageBucket`. Reference to targets that belong to the backend. A backend may be a set of target groups or an Object Storage bucket. For details about backend types, see documentation.
healthchecks[]	HealthCheck Health checks to perform on targets from target groups. For details about health checking, see documentation. If no health checks are specified, active health checking is not performed.
tls	BackendTls Settings for TLS connections between load balancer nodes and backend targets. If specified, the load balancer establishes HTTPS (HTTP over TLS) connections with targets and compares received certificates with the one specified in BackendTls.validationContext. If not specified, the load balancer establishes unencrypted HTTP connections with targets.
useHttp2	bool Enables HTTP/2 usage in connections between load balancer nodes and backend targets. Default value: `false`, HTTP/1.1 is used.

LoadBalancingConfig

A load balancing configuration resource.

Field	Description
panicThreshold	int64 Threshold for panic mode. If percentage of healthy backends in the group drops below threshold, panic mode will be activated and traffic will be routed to all backends, regardless of their health check status. This helps to avoid overloading healthy backends. For details about panic mode, see documentation. If the value is `0`, panic mode will never be activated and traffic is routed only to healthy backends at all times. Default value: `0`.
localityAwareRoutingPercent	int64 Percentage of traffic that a load balancer node sends to healthy backends in its availability zone. The rest is divided equally between other zones. For details about zone-aware routing, see documentation. If there are no healthy backends in an availability zone, all the traffic is divided between other zones. If `strictLocality` is `true`, the specified value is ignored. A load balancer node sends all the traffic within its availability zone, regardless of backends' health. Default value: `0`.
strictLocality	bool Specifies whether a load balancer node should only send traffic to backends in its availability zone, regardless of their health, and ignore backends in other zones. If set to `true` and there are no healthy backends in the zone, the node in this zone will respond to incoming traffic with errors. For details about strict locality, see documentation. If `strict_locality` is `true`, the value specified in `localityAwareRoutingPercent` is ignored. Default value: `false`.
mode	enum LoadBalancingMode Load balancing mode for the backend. For details about load balancing modes, see documentation. `ROUND_ROBIN`: Round robin load balancing mode. All endpoints of the backend take their turns to receive requests attributed to the backend. `RANDOM`: Random load balancing mode. Default value. For a request attributed to the backend, an endpoint that receives it is picked at random. `LEAST_REQUEST`: Least request load balancing mode. To pick an endpoint that receives a request attributed to the backend, the power of two choices algorithm is used; that is, two endpoints are picked at random, and the request is sent to the one which has the fewest active requests. `MAGLEV_HASH`: Maglev hashing load balancing mode. Each endpoint is hashed, and a hash table with 65537 rows is filled accordingly, so that every endpoint occupies the same amount of rows. An attribute of each request is also hashed by the same function (if session affinity is enabled for the backend group, the attribute to hash is specified in session affinity configuration). The row with the same number as the resulting value is looked up in the table to determine the endpoint that receives the request. If the backend group with session affinity enabled contains more than one backend with positive weight, endpoints for backends with `MAGLEV_HASH` load balancing mode are picked at `RANDOM` instead.

unhealthyThreshold	int64 Number of consecutive failed health checks required to mark a healthy target as unhealthy. Both `0` and `1` values amount to one unsuccessful check required. The value is ignored if a health check is failed due to an HTTP `503 Service Unavailable` response from the target (not applicable to TCP stream health checks). The target is immediately marked unhealthy. Default value: `0`.
