DESCRIPTION

Elastic Load Balancing

A load balancer distributes incoming traffic across targets, such as your EC2 instances. This enables you to increase the availability of your application. The load balancer also monitors the health of its registered targets and ensures that it routes traffic only to healthy targets. You configure your load balancer to accept incoming traffic by specifying one or more listeners, which are configured with a protocol and port number for connections from clients to the load balancer. You configure a target group with a protocol and port number for connections from the load balancer to the targets, and with health check settings to be used when checking the health status of the targets.

Elastic Load Balancing supports the following types of load balancers: Application Load Balancers, Network Load Balancers, Gateway Load Balancers, and Classic Load Balancers. This reference covers the following load balancer types:

Application Load Balancer - Operates at the application layer (layer 7) and supports HTTP and HTTPS.
Network Load Balancer - Operates at the transport layer (layer 4) and supports TCP, TLS, and UDP.
Gateway Load Balancer - Operates at the network layer (layer 3).

For more information, see the Elastic Load Balancing User Guide (https://docs.aws.amazon.com/elasticloadbalancing/latest/userguide/).

All Elastic Load Balancing operations are idempotent, which means that they complete at most one time. If you repeat an operation, it succeeds.

For the AWS API documentation, see https://docs.aws.amazon.com/goto/WebAPI/elasticloadbalancing-2015-12-01

METHODS

AddListenerCertificates

Certificates => ArrayRef[Paws::ELBv2::Certificate]
ListenerArn => Str

Each argument is described in detail in: Paws::ELBv2::AddListenerCertificates

Returns: a Paws::ELBv2::AddListenerCertificatesOutput instance

Adds the specified SSL server certificate to the certificate list for the specified HTTPS or TLS listener.

If the certificate in already in the certificate list, the call is successful but the certificate is not added again.

For more information, see HTTPS listeners (https://docs.aws.amazon.com/elasticloadbalancing/latest/application/create-https-listener.html) in the Application Load Balancers Guide or TLS listeners (https://docs.aws.amazon.com/elasticloadbalancing/latest/network/create-tls-listener.html) in the Network Load Balancers Guide.

AddTags

ResourceArns => ArrayRef[Str|Undef]
Tags => ArrayRef[Paws::ELBv2::Tag]

Each argument is described in detail in: Paws::ELBv2::AddTags

Returns: a Paws::ELBv2::AddTagsOutput instance

Adds the specified tags to the specified Elastic Load Balancing resource. You can tag your Application Load Balancers, Network Load Balancers, Gateway Load Balancers, target groups, listeners, and rules.

Each tag consists of a key and an optional value. If a resource already has a tag with the same key, AddTags updates its value.

CreateListener

DefaultActions => ArrayRef[Paws::ELBv2::Action]
LoadBalancerArn => Str
[AlpnPolicy => ArrayRef[Str|Undef]]
[Certificates => ArrayRef[Paws::ELBv2::Certificate]]
[Port => Int]

[Tags => ArrayRef[Paws::ELBv2::Tag]]

Each argument is described in detail in: Paws::ELBv2::CreateListener

Returns: a Paws::ELBv2::CreateListenerOutput instance

Creates a listener for the specified Application Load Balancer, Network Load Balancer, or Gateway Load Balancer.

For more information, see the following:

[IpAddressType => Str]
[Scheme => Str]
[SecurityGroups => ArrayRef[Str|Undef]]
[SubnetMappings => ArrayRef[Paws::ELBv2::SubnetMapping]]
[Subnets => ArrayRef[Str|Undef]]
[Tags => ArrayRef[Paws::ELBv2::Tag]]
[Type => Str]

Each argument is described in detail in: Paws::ELBv2::CreateLoadBalancer

Returns: a Paws::ELBv2::CreateLoadBalancerOutput instance

Creates an Application Load Balancer, Network Load Balancer, or Gateway Load Balancer.

For more information, see the following:

Network Load Balancers (https://docs.aws.amazon.com/elasticloadbalancing/latest/network/network-load-balancers.html)
Gateway Load Balancers (https://docs.aws.amazon.com/elasticloadbalancing/latest/gateway/gateway-load-balancers.html)

This operation is idempotent, which means that it completes at most one time. If you attempt to create multiple load balancers with the same settings, each call succeeds.

CreateRule

Actions => ArrayRef[Paws::ELBv2::Action]

Creates a rule for the specified listener. The listener must be associated with an Application Load Balancer.

Each rule consists of a priority, one or more actions, and one or more conditions. Rules are evaluated in priority order, from the lowest value to the highest value. When the conditions for a rule are met, its actions are performed. If the conditions for no rules are met, the actions for the default rule are performed. For more information, see Listener rules (https://docs.aws.amazon.com/elasticloadbalancing/latest/application/load-balancer-listeners.html#listener-rules) in the Application Load Balancers Guide.

CreateTargetGroup

Target groups for your Gateway Load Balancers (https://docs.aws.amazon.com/elasticloadbalancing/latest/gateway/target-groups.html)

This operation is idempotent, which means that it completes at most one time. If you attempt to create multiple target groups with the same settings, each call succeeds.

DeleteListener

ListenerArn => Str

Each argument is described in detail in: Paws::ELBv2::DeleteListener

Returns: a Paws::ELBv2::DeleteListenerOutput instance

Deletes the specified listener.

Alternatively, your listener is deleted when you delete the load balancer to which it is attached.

Returns: a Paws::ELBv2::DeleteLoadBalancerOutput instance

Deletes the specified Application Load Balancer, Network Load Balancer, or Gateway Load Balancer. Deleting a load balancer also deletes its listeners.

You can't delete a load balancer if deletion protection is enabled. If the load balancer does not exist or has already been deleted, the call succeeds.

Deleting a load balancer does not affect its registered targets. For example, your EC2 instances continue to run and are still registered to their target groups. If you no longer need these EC2 instances, you can stop or terminate them.

DeleteRule

RuleArn => Str

Each argument is described in detail in: Paws::ELBv2::DeleteRule

TargetGroupArn => Str
Targets => ArrayRef[Paws::ELBv2::TargetDescription]

Each argument is described in detail in: Paws::ELBv2::DeregisterTargets

Returns: a Paws::ELBv2::DeregisterTargetsOutput instance

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.

Each argument is described in detail in: Paws::ELBv2::RegisterTargets

Returns: a Paws::ELBv2::RegisterTargetsOutput instance

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.

With a Network Load Balancer, you cannot register instances by instance ID if they have the following instance types: C1, CC1, CC2, CG1, CG2, CR1, CS1, G1, G2, HI1, HS1, M1, M2, M3, and T1. You can register instances of these types by IP address.

Each argument is described in detail in: Paws::ELBv2::SetSecurityGroups

Returns: a Paws::ELBv2::SetSecurityGroupsOutput instance
