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 two types of load balancers: Classic Load Balancers and Application Load Balancers. A Classic Load Balancer makes routing and load balancing decisions either at the transport layer (TCP/SSL) or the application layer (HTTP/HTTPS), and supports either EC2-Classic or a VPC. An Application Load Balancer makes routing and load balancing decisions at the application layer (HTTP/HTTPS), supports path-based routing, and can route requests to one or more ports on each EC2 instance or container instance in your virtual private cloud (VPC). For more information, see the Elastic Load Balancing User Guide.

This reference covers the 2015-12-01 API, which supports Application Load Balancers. The 2012-06-01 API supports Classic Load Balancers.

To get started, complete the following tasks:

1. Create an Application Load Balancer using CreateLoadBalancer.

2. Create a target group using CreateTargetGroup.

3. Register targets for the target group using RegisterTargets.

4. Create one or more listeners for your load balancer using CreateListener.

5. (Optional) Create one or more rules for content routing based on URL using CreateRule.

To delete an Application Load Balancer and its related resources, complete the following tasks:

1. Delete the load balancer using DeleteLoadBalancer.

2. Delete the target group using DeleteTargetGroup.

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

METHODS

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 resource. You can tag your
Application Load Balancers and your target groups.

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.

To list the current tags for your resources, use DescribeTags. To remove tags from your resources, use RemoveTags.

CreateListener(DefaultActions => ArrayRef[Paws::ELBv2::Action], LoadBalancerArn => Str, Port => Int, Protocol => Str, [Certificates => ArrayRef[Paws::ELBv2::Certificate], SslPolicy => Str])

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.

You can create up to 10 listeners per load balancer.

To update a listener, use ModifyListener. When you are finished with a listener, you can delete it using DeleteListener. If you are finished with both the listener and the load balancer, you can delete them both using DeleteLoadBalancer.

For more information, see Listeners for Your Application Load Balancers in the Application Load Balancers Guide.

CreateLoadBalancer(Name => Str, Subnets => ArrayRef[Str|Undef], [IpAddressType => Str, Scheme => Str, SecurityGroups => ArrayRef[Str|Undef], Tags => ArrayRef[Paws::ELBv2::Tag]])

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

Returns: a Paws::ELBv2::CreateLoadBalancerOutput instance

  Creates an Application Load Balancer.

When you create a load balancer, you can specify security groups, subnets, IP address type, and tags. Otherwise, you could do so later using SetSecurityGroups, SetSubnets, SetIpAddressType, and AddTags.

To create listeners for your load balancer, use CreateListener. To describe your current load balancers, see DescribeLoadBalancers. When you are finished with a load balancer, you can delete it using DeleteLoadBalancer.

You can create up to 20 load balancers per region per account. You can request an increase for the number of load balancers for your account. For more information, see Limits for Your Application Load Balancer in the Application Load Balancers Guide.

For more information, see Application Load Balancers in the Application Load Balancers Guide.

CreateRule(Actions => ArrayRef[Paws::ELBv2::Action], Conditions => ArrayRef[Paws::ELBv2::RuleCondition], ListenerArn => Str, Priority => Int)

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

Returns: a Paws::ELBv2::CreateRuleOutput instance

  Creates a rule for the specified listener.

Each rule can have one action and one condition. Rules are evaluated in priority order, from the lowest value to the highest value. When the condition for a rule is met, the specified action is taken. If no conditions are met, the default action for the default rule is taken. For more information, see Listener Rules in the Application Load Balancers Guide.

To view your current rules, use DescribeRules. To update a rule, use ModifyRule. To set the priorities of your rules, use SetRulePriorities. To delete a rule, use DeleteRule.

CreateTargetGroup(Name => Str, Port => Int, Protocol => Str, VpcId => Str, [HealthCheckIntervalSeconds => Int, HealthCheckPath => Str, HealthCheckPort => Str, HealthCheckProtocol => Str, HealthCheckTimeoutSeconds => Int, HealthyThresholdCount => Int, Matcher => Paws::ELBv2::Matcher, UnhealthyThresholdCount => Int])

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

Returns: a Paws::ELBv2::CreateTargetGroupOutput instance

  Creates a target group.

To register targets with the target group, use RegisterTargets. To update the health check settings for the target group, use ModifyTargetGroup. To monitor the health of targets in the target group, use DescribeTargetHealth.

To route traffic to the targets in a target group, specify the target group in an action using CreateListener or CreateRule.

To delete a target group, use DeleteTargetGroup.

For more information, see Target Groups for Your Application Load Balancers in the Application Load Balancers Guide.

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 it is attached to using DeleteLoadBalancer.

DeleteLoadBalancer(LoadBalancerArn => Str)

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

Returns: a Paws::ELBv2::DeleteLoadBalancerOutput instance

  Deletes the specified Application Load Balancer and its attached
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.
