2025/11/13 - Elastic Load Balancing - 9 updated api methods
Changes QUIC and TCP_QUIC protocol support for Network Load Balancer (NLB). This capability enables customers to forward QUIC traffic to their targets with ultra-low latency while maintaining session stickiness using QUIC Connection IDs.
{'Protocol': {'QUIC', 'TCP_QUIC'}}
Response {'Listeners': {'Protocol': {'QUIC', 'TCP_QUIC'}}}
Creates a listener for the specified Application Load Balancer, Network Load Balancer, or Gateway Load Balancer.
For more information, see the following:
This operation is idempotent, which means that it completes at most one time. If you attempt to create multiple listeners with the same settings, each call succeeds.

This name must be unique per region per account, can have a maximum of 32 characters, must contain only alphanumeric characters or hyphens, and must not begin or end with a hyphen.
string
The protocol to use for routing traffic to the targets. For Application Load Balancers, the supported protocols are HTTP and HTTPS. For Network Load Balancers, the supported protocols are TCP, TLS, UDP, or TCP_UDP. For Gateway Load Balancers, the supported protocol is GENEVE. A TCP_UDP listener must be associated with a TCP_UDP target group. If the target is a Lambda function, this parameter does not apply.
string
[HTTP/HTTPS protocol] The protocol version. Specify GRPC to send requests to targets using gRPC. Specify HTTP2 to send requests to targets using HTTP/2. The default is HTTP1, which sends requests to targets using HTTP/1.1.
integer

string
The identifier of the virtual private cloud (VPC). If the target is a Lambda function, this parameter does not apply. Otherwise, this parameter is required.
string
The protocol the load balancer uses when performing health checks on targets. For Application Load Balancers, the default is HTTP. For Network Load Balancers and Gateway Load Balancers, the default is TCP. The TCP protocol is not supported for health checks if the protocol of the target group is HTTP or HTTPS. The GENEVE, TLS, UDP, and TCP_UDP protocols are not supported for health checks.
string
The port the load balancer uses when performing health checks on targets. If the protocol is HTTP, HTTPS, TCP, TLS, UDP, or TCP_UDP, the default is traffic-port, which is the port on which each target receives traffic from the load balancer. If the protocol is GENEVE, the default is port 80.
boolean
Indicates whether health checks are enabled. If the target type is lambda, health checks are disabled by default but can be enabled. If the target type is instance, ip, or alb, health checks are always enabled and can't be disabled.
string

integer
The approximate amount of time, in seconds, between health checks of an individual target. The range is 5-300. If the target group protocol is TCP, TLS, UDP, TCP_UDP, HTTP or HTTPS, the default is 30 seconds. If the target group protocol is GENEVE, the default is 10 seconds. If the target type is lambda, the default is 35 seconds.
integer

{'Targets': {'QuicServerId': 'string'}}
Deregisters the specified targets from the specified target group. After the targets are deregistered, they no longer receive traffic from the load balancer.
The load balancer stops sending requests to targets that are deregistering, but uses connection draining to ensure that in-flight traffic completes on the existing connections. This deregistration delay is configured by default but can be updated for each target group.
For more information, see the following:
Deregistration delay in the Application Load Balancers User Guide
Deregistration delay in the Network Load Balancers User Guide
Deregistration delay in the Gateway Load Balancers User Guide
Note: If the specified target does not exist, the action returns successfully.

[REQUIRED]
The targets. If you specified a port override when you registered a target, you must specify both the target ID and the port when you deregister it.
(dict) --
Information about a target.
Id (string) -- [REQUIRED]
The ID of the target. If the target type of the target group is instance, specify an instance ID. If the target type is ip, specify an IP address. If the target type is lambda, specify the ARN of the Lambda function. If the target type is alb, specify the ARN of the Application Load Balancer target.
Port (integer) --
The port on which the target is listening. If the target group protocol is GENEVE, the supported port is 6081. If the target type is alb, the targeted Application Load Balancer must have at least one listener whose port matches the target group port. This parameter is not used if the target is a Lambda function.
AvailabilityZone (string) --

For Application Load Balancer target groups, the specified Availability Zone value is only applicable when cross-zone load balancing is off. Otherwise the parameter is ignored and treated as all.
This parameter is not supported if the target type of the target group is instance or alb.
If the target type is ip and the IP address is in a subnet of the VPC for the target group, the Availability Zone is automatically detected and this parameter is optional. If the IP address is outside the VPC, this parameter is required.
For Application Load Balancer target groups with cross-zone load balancing off, if the target type is ip and the IP address is outside of the VPC for the target group, this should be an Availability Zone inside the VPC for the target group.
If the target type is lambda, this parameter is optional and the only supported value is all.
QuicServerId (string) --
The server ID for the targets. This value is required if the protocol is QUIC or TCP_QUIC and can't be used with other protocols.
The ID consists of the 0x prefix followed by 16 hexadecimal characters. Any letters must be lowercase. The value must be unique at the listener level. You can't modify the server ID for a registered target. You must deregister the target and then provide a new server ID when you register the target again.

If the target type is alb, the targeted Application Load Balancer must have at least one listener whose port matches the target group port. This parameter is not used if the target is a Lambda function.
AvailabilityZone (string) --
An Availability Zone or all. This determines whether the target receives traffic from the load balancer nodes in the specified Availability Zone or from all enabled Availability Zones for the load balancer.
For Application Load Balancer target groups, the specified Availability Zone value is only applicable when cross-zone load balancing is off. Otherwise the parameter is ignored and treated as all.
This parameter is not supported if the target type of the target group is instance or alb.
If the target type is ip and the IP address is in a subnet of the VPC for the target group, the Availability Zone is automatically detected and this parameter is optional. If the IP address is outside the VPC, this parameter is required.
For Application Load Balancer target groups with cross-zone load balancing off, if the target type is ip and the IP address is outside of the VPC for the target group, this should be an Availability Zone inside the VPC for the target group.
If the target type is lambda, this parameter is optional and the only supported value is all.
QuicServerId (string) --
The server ID for the targets. This value is required if the protocol is QUIC or TCP_QUIC and can't be used with other protocols.
The ID consists of the 0x prefix followed by 16 hexadecimal characters. Any letters must be lowercase. The value must be unique at the listener level. You can't modify the server ID for a registered target. You must deregister the target and then provide a new server ID when you register the target again.

Replaces the specified properties of the specified listener. Any properties that you do not specify remain unchanged.
Changing the protocol from HTTPS to HTTP, or from TLS to TCP, removes the security policy and default certificate properties. If you change the protocol from HTTP to HTTPS, or from TCP to TLS, you must add the security policy and default certificate properties.
To add an item to a list, remove an item from a list, or update an item in a list, you must provide the entire list. For example, to add an action, specify a list with the current actions plus the new action.

[REQUIRED]
The Amazon Resource Name (ARN) of the target group.
string
The protocol the load balancer uses when performing health checks on targets. For Application Load Balancers, the default is HTTP. For Network Load Balancers and Gateway Load Balancers, the default is TCP. The TCP protocol is not supported for health checks if the protocol of the target group is HTTP or HTTPS. It is supported for health checks only if the protocol of the target group is TCP, TLS, UDP, or TCP_UDP. The GENEVE, TLS, UDP, and TCP_UDP protocols are not supported for health checks.
string
The port the load balancer uses when performing health checks on targets.
string
[HTTP/HTTPS health checks] The destination for health checks on the targets.
[HTTP1 or HTTP2 protocol version] The ping path. The default is /.
[GRPC protocol version] The path of a custom health check method with the format /package.service/method. The default is /Amazon Web Services.ALB/healthcheck.
boolean
Indicates whether health checks are enabled. If the target type is lambda, health checks are disabled by default but can be enabled. If the target type is instance, ip, or alb, health checks are always enabled and can't be disabled.

integer
[HTTP/HTTPS health checks] The amount of time, in seconds, during which no response means a failed health check.
integer
The number of consecutive health checks successes required before considering an unhealthy target healthy.
integer
The number of consecutive health check failures required before considering the target unhealthy.

For target groups with a protocol of HTTP or HTTPS, the range is 200-499. For target groups with a protocol of GENEVE, the range is 200-399.
HttpCode (string) --
For Application Load Balancers, you can specify values between 200 and 499, with the default value being 200. You can specify multiple values (for example, "200,202") or a range of values (for example, "200-299").
For Network Load Balancers, you can specify values between 200 and 599, with the default value being 200-399. You can specify multiple values (for example, "200,202") or a range of values (for example, "200-299").
For Gateway Load Balancers, this must be "200–399".
Note that when using shorthand syntax, some values such as commas need to be escaped.

Registers the specified targets with the specified target group.
If the target is an EC2 instance, it must be in the running state when you register it.
By default, the load balancer routes requests to registered targets using the protocol and port for the target group. Alternatively, you can override the port for a target when you register it. You can register each EC2 instance or IP address with the same target group multiple times using different ports.

string
[REQUIRED]
The Amazon Resource Name (ARN) of the target group.
list
[REQUIRED]
The targets.
(dict) --
Information about a target.
Id (string) -- [REQUIRED]
The ID of the target. If the target type of the target group is instance, specify an instance ID. If the target type is ip, specify an IP address. If the target type is lambda, specify the ARN of the Lambda function. If the target type is alb, specify the ARN of the Application Load Balancer target.
Port (integer) --
The port on which the target is listening. If the target group protocol is GENEVE, the supported port is 6081. If the target type is alb, the targeted Application Load Balancer must have at least one listener whose port matches the target group port. This parameter is not used if the target is a Lambda function.
AvailabilityZone (string) --
An Availability Zone or all. This determines whether the target receives traffic from the load balancer nodes in the specified Availability Zone or from all enabled Availability Zones for the load balancer.
For Application Load Balancer target groups, the specified Availability Zone value is only applicable when cross-zone load balancing is off. Otherwise the parameter is ignored and treated as all.
This parameter is not supported if the target type of the target group is instance or alb.
If the target type is ip and the IP address is in a subnet of the VPC for the target group, the Availability Zone is automatically detected and this parameter is optional. If the IP address is outside the VPC, this parameter is required.
For Application Load Balancer target groups with cross-zone load balancing off, if the target type is ip and the IP address is outside of the VPC for the target group, this should be an Availability Zone inside the VPC for the target group.
If the target type is lambda, this parameter is optional and the only supported value is all.
QuicServerId (string) --
The server ID for the targets. This value is required if the protocol is QUIC or TCP_QUIC and can't be used with other protocols.
The ID consists of the 0x prefix followed by 16 hexadecimal characters. Any letters must be lowercase. The value must be unique at the listener level. You can't modify the server ID for a registered target. You must deregister the target and then provide a new server ID when you register the target again.
