C# (CSharp) Amazon.ElasticLoadBalancing.Model Namespace

Each tag consists of a key and an optional value. If a tag with the same key is already associated with the load balancer, AddTags updates its value.

For more information, see Tag Your Classic Load Balancer in the Classic Load Balancers Guide.

The AppCookieStickinessPolicy data type.

For more information, see Security Groups for Load Balancers in a VPC in the Classic Load Balancers Guide.

The out for the ApplySecurityGroupsToLoadBalancer action.

Adds one or more subnets to the set of configured subnets in the Amazon Virtual Private Cloud (Amazon VPC) for the load balancer.

The load balancers evenly distribute requests across all of the registered subnets. For more information, see Deploy Elastic Load Balancing in Amazon VPC in the Elastic Load Balancing Developer Guide .

Specifies the health check settings to use for evaluating the health state of your back-end instances.

For more information, see Health Check in the Elastic Load Balancing Developer Guide .

This policy is similar to the policy created by CreateLBCookieStickinessPolicy, except that the lifetime of the special Elastic Load Balancing cookie, AWSELB, follows the lifetime of the application-generated cookie specified in the policy configuration. The load balancer only inserts a new stickiness cookie when the application response includes a new application cookie.

If the application cookie is explicitly removed or expires, the session stops being sticky until a new application cookie is issued.

For more information, see Application-Controlled Session Stickiness in the Classic Load Balancers Guide.

When a load balancer implements this policy, the load balancer uses a special cookie to track the instance for each request. When the load balancer receives a request, it first checks to see if this cookie is present in the request. If so, the load balancer sends the request to the application server specified in the cookie. If not, the load balancer sends the request to a server that is chosen based on the existing load-balancing algorithm.

A cookie is inserted into the response for binding subsequent requests from the same user to that server. The validity of the cookie is based on the cookie expiration time, which is specified in the policy configuration.

For more information, see Duration-Based Session Stickiness in the Classic Load Balancers Guide.

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

Creates a new policy that contains the necessary attributes depending on the policy type. Policies are settings that are saved for your Elastic LoadBalancer and that can be applied to the front-end listener, or the back-end application server, depending on your policy type.

The output for the CreateLoadBalancer action.

The CrossZoneLoadBalancing data type.

Deletes listeners from the LoadBalancer for the specified port.

Deregisters instances from the LoadBalancer. Once the instance is deregistered, it will stop receiving traffic from the LoadBalancer.

In order to successfully call this API, the same account credentials as those used to create the LoadBalancer must be provided.

Returns the current state of the specified instances registered with the specified load balancer. If no instances are specified, the state of all the instances registered with the load balancer is returned.

NOTE: You must provide the same account credentials as those that were used to create the load balancer.

The output for the DescribeInstanceHealth action.

The following element is returned in a structure named DescribeLoadBalancerAttributesResult .

Returns detailed descriptions of the policies. If you specify a LoadBalancer name, the operation returns either the descriptions of the specified policies, or descriptions of all the policies created for the LoadBalancer. If you don't specify a LoadBalancer name, the operation returns descriptions of the specified sample policies, or descriptions of all the sample policies. The names of the sample policies have the ELBSample- prefix.

The output for the DescribeLoadBalancerPolicies action.

Returns meta-information on the specified load balancer policies defined by the Elastic Load Balancing service. The policy types that are returned from this action can be used in a CreateLoadBalancerPolicy action to instantiate specific policy configurations that will be applied to a load balancer.

The output for the DescribeLoadBalancerPolicyTypes action.

Returns detailed configuration information for the specified LoadBalancers. If no LoadBalancers are specified, the operation returns configuration information for all LoadBalancers created by the caller.

NOTE: The client must have created the specified input LoadBalancers in order to retrieve this information; the client must provide the same account credentials as those that were used to create the LoadBalancer.

The output for the DescribeLoadBalancers action.

Removes subnets from the set of configured subnets in the Amazon Virtual Private Cloud (Amazon VPC) for the load balancer.

After a subnet is removed all of the EC2 instances registered with the load balancer that are in the removed subnet will go into the OutOfService state. When a subnet is removed, the load balancer will balance the traffic among the remaining routable subnets for the load balancer.

The output for the DetachLoadBalancerFromSubnets action.

There must be at least one Availability Zone registered with a load balancer at all times. After an Availability Zone is removed, all instances registered with the load balancer that are in the removed Availability Zone go into the OutOfService state. Then, the load balancer attempts to equally balance the traffic among its remaining Availability Zones.

For more information, see Add or Remove Availability Zones in the Classic Load Balancers Guide.

The load balancer evenly distributes requests across all its registered Availability Zones that contain instances.

For more information, see Add or Remove Availability Zones in the Classic Load Balancers Guide.

The HealthCheck data type.

The LBCookieStickinessPolicy data type.

The Listener data type.

The LoadBalancerAttributes data type.

You can modify the load balancer attributes, such as AccessLogs, ConnectionDraining, and CrossZoneLoadBalancing by either enabling or disabling them. Or, you can modify the load balancer attribute ConnectionSettings by specifying an idle connection timeout value for your load balancer.

For more information, see the following in the Classic Load Balancers Guide:

• Cross-Zone Load Balancing

• Connection Draining

• Access Logs

• Idle Connection Timeout

The PolicyAttributeDescription data type. This data type is used to describe the attributes and values associated with a policy.

The PolicyAttributeTypeDescription data type. This data type is used to describe values that are acceptable for the policy attribute.

The PolicyDescription data type.

The PolicyTypeDescription data type.

Adds new instances to the LoadBalancer.

Once the instance is registered, it starts receiving traffic and requests from the LoadBalancer. Any instance that is not in any of the Availability Zones registered for the LoadBalancer will be moved to the OutOfService state. It will move to the InService state when the Availability Zone is added to the LoadBalancer.

NOTE: In order for this call to be successful, the client must have created the LoadBalancer. The client must provide the same account credentials as those that were used to create the LoadBalancer.

NOTE: Completion of this API does not guarantee that operation has completed. Rather, it means that the request has been registered and the changes will happen shortly.

The output for the RegisterInstancesWithLoadBalancer action.

For more information about updating your SSL certificate, see Replace the SSL Certificate for Your Load Balancer in the Classic Load Balancers Guide.

Each time you use SetLoadBalancerPoliciesForBackendServer to enable the policies, use the PolicyNames parameter to list the policies that you want to enable.

You can use DescribeLoadBalancers or DescribeLoadBalancerPolicies to verify that the policy is associated with the EC2 instance.

For more information about enabling back-end instance authentication, see Configure Back-end Instance Authentication in the Classic Load Balancers Guide. For more information about Proxy Protocol, see Configure Proxy Protocol Support in the Classic Load Balancers Guide.

This data type is used as a response element in the DescribeLoadBalancers action. For information about Elastic Load Balancing security groups, go to Using Security Groups With Elastic Load Balancing in the Elastic Load Balancing Developer Guide .
