Properties

Name	Type	Description
HealthCheckConfig	object	Property healthCheckConfig: The configuration of health checks.
ServerGroupName	object	Property serverGroupName: The name of the server group.
VpcId	object	Property vpcId: The ID of the virtual private cloud (VPC).
ConnectionDrainConfig	object	Property connectionDrainConfig: Configuration related to graceful connection interruption.Enable graceful connection interruption. After the backend server is removed or the health check fails, the load balancing allows the existing connection to be transmitted normally within a certain period of time.Note: Basic Edition instances do not support enabling graceful connection interruption. Only Standard Edition and WAF Enhanced Edition instances support it.Server type and IP type server group support graceful connection interruption. Function Compute type does not support it.
Protocol	object	Property protocol: The backend protocol.
ResourceGroupId	object	Property resourceGroupId: The ID of the resource group.
Scheduler	object	Property scheduler: The scheduling algorithm.
ServerGroupType	object	Property serverGroupType: The type of the server group.
ServiceName	object	Property serviceName: This parameter is available only if the ALB Ingress controller is used.
SlowStartConfig	object	Property slowStartConfig: Slow start related configuration.After slow start is enabled, the backend server newly added to the backend server group will be preheated within the set time period, and the number of requests forwarded to the server will increase linearly.Note: Basic Edition instances do not support slow start, only Standard Edition and WAF Enhanced Edition instances support it.Server type and IP type server groups support slow start configuration, but Function Compute type does not.Slow start can only be enabled when the backend scheduling algorithm is the weighted polling algorithm.
StickySessionConfig	object	Property stickySessionConfig: The configuration of session persistence.
Tags	TagsProperty[]	Property tags: Tags to attach to instance.
UchConfig	object	Property uchConfig: URL consistency hash parameter configuration.
UpstreamKeepaliveEnabled	object	Property upstreamKeepaliveEnabled: Whether to enable upstream keepalive.

HealthCheckConfig^Required

public object HealthCheckConfig { get; set; }

• Type: object

Property healthCheckConfig: The configuration of health checks.

---

ServerGroupName^Required

public object ServerGroupName { get; set; }

• Type: object

Property serverGroupName: The name of the server group.

The name must be 2 to 128 characters in length, and can contain letters, digits, periods (.), underscores (_), and hyphens (-). The name must start with a letter.

---

VpcId^Required

public object VpcId { get; set; }

• Type: object

Property vpcId: The ID of the virtual private cloud (VPC).

You can add only servers that are deployed in the specified VPC to the server group. Note: This parameter is required if the ServerGroupType parameter is set to Instance or Ip. Note: This parameter takes effect when the ServerGroupType parameter is set to Instance or Ip.

---

ConnectionDrainConfig^Optional

public object ConnectionDrainConfig { get; set; }

• Type: object

Property connectionDrainConfig: Configuration related to graceful connection interruption.Enable graceful connection interruption. After the backend server is removed or the health check fails, the load balancing allows the existing connection to be transmitted normally within a certain period of time.Note: Basic Edition instances do not support enabling graceful connection interruption. Only Standard Edition and WAF Enhanced Edition instances support it.Server type and IP type server group support graceful connection interruption. Function Compute type does not support it.

---

Protocol^Optional

public object Protocol { get; set; }

• Type: object

Property protocol: The backend protocol.

Valid values: HTTP (default): The server group can be associated with HTTPS, HTTP, and QUIC listeners. HTTPS: The server group can be associated with HTTPS listeners. gRPC: The server group can be associated with HTTPS and QUIC listeners. Note: If the ServerGroupType parameter is set to Fc, you can set Protocol only to HTTP.

---

ResourceGroupId^Optional

public object ResourceGroupId { get; set; }

• Type: object

Property resourceGroupId: The ID of the resource group.

---

Scheduler^Optional

public object Scheduler { get; set; }

• Type: object

Property scheduler: The scheduling algorithm.

Valid values: Wrr (default): The weighted round-robin algorithm is used. Backend servers that have higher weights receive more requests than those that have lower weights. Wlc: The weighted least connections algorithm is used. Requests are distributed based on the weights and the number of connections to backend servers. If two backend servers have the same weight, the backend server that has fewer connections is expected to receive more requests. Sch: The consistent hashing algorithm is used. Requests from the same source IP address are distributed to the same backend server. Note: This parameter takes effect when the ServerGroupType parameter is set to Instance or Ip.

---

ServerGroupType^Optional

public object ServerGroupType { get; set; }

• Type: object

Property serverGroupType: The type of the server group.

Valid values: Instance (default): allows you add servers by specifying Ecs, Ens, or Eci. Ip: allows you to add servers by specifying IP addresses. Fc: allows you to add servers by specifying functions of Function Compute.

---

ServiceName^Optional

public object ServiceName { get; set; }

• Type: object

Property serviceName: This parameter is available only if the ALB Ingress controller is used.

In this case, set the parameter to the name of the Kubernetes Service that is associated with the server group.

---

SlowStartConfig^Optional

public object SlowStartConfig { get; set; }

• Type: object

Property slowStartConfig: Slow start related configuration.After slow start is enabled, the backend server newly added to the backend server group will be preheated within the set time period, and the number of requests forwarded to the server will increase linearly.Note: Basic Edition instances do not support slow start, only Standard Edition and WAF Enhanced Edition instances support it.Server type and IP type server groups support slow start configuration, but Function Compute type does not.Slow start can only be enabled when the backend scheduling algorithm is the weighted polling algorithm.

---

StickySessionConfig^Optional

public object StickySessionConfig { get; set; }

• Type: object

Property stickySessionConfig: The configuration of session persistence.

Note: This parameter is required if the ServerGroupType parameter is set to Instance or Ip.

---

Tags^Optional

public TagsProperty[] Tags { get; set; }

• Type: TagsProperty[]

Property tags: Tags to attach to instance.

Max support 20 tags to add during create instance. Each tag with two properties Key and Value, and Key is required.

---

UchConfig^Optional

public object UchConfig { get; set; }

• Type: object

Property uchConfig: URL consistency hash parameter configuration.

---

UpstreamKeepaliveEnabled^Optional

public object UpstreamKeepaliveEnabled { get; set; }

• Type: object

Property upstreamKeepaliveEnabled: Whether to enable upstream keepalive.
