Interface AmazonElasticLoadBalancing

  • All Known Subinterfaces:
    AmazonElasticLoadBalancingAsync
    All Known Implementing Classes:
    AbstractAmazonElasticLoadBalancing, AbstractAmazonElasticLoadBalancingAsync, AmazonElasticLoadBalancingAsyncClient, AmazonElasticLoadBalancingClient 

    @Generated(value="com.amazonaws:aws-java-sdk-code-generator")
public interface AmazonElasticLoadBalancing
    Interface for accessing Elastic Load Balancing.

    Note: Do not directly implement this interface, new methods are added to it regularly. Extend from AbstractAmazonElasticLoadBalancing instead.

    Elastic Load Balancing

    A load balancer can distribute incoming traffic across your EC2 instances. This enables you to increase the availability of your application. The load balancer also monitors the health of its registered instances and ensures that it routes traffic only to healthy instances. 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 and a protocol and port number for connections from the load balancer to the instances.

    Elastic Load Balancing supports three types of load balancers: Application Load Balancers, Network Load Balancers, and Classic Load Balancers. You can select a load balancer based on your application needs. For more information, see the Elastic Load Balancing User Guide.

    This reference covers the 2012年06月01日 API, which supports Classic Load Balancers. The 2015年12月01日 API supports Application Load Balancers and Network Load Balancers.

    To get started, create a load balancer with one or more listeners using CreateLoadBalancer. Register your instances with the load balancer using RegisterInstancesWithLoadBalancer.

    All Elastic Load Balancing operations are idempotent, which means that they complete at most one time. If you repeat an operation, it succeeds with a 200 OK response code.

    • Method Detail

      • setEndpoint

        @Deprecated
void setEndpoint(String endpoint)
        Deprecated. use AwsClientBuilder#setEndpointConfiguration(AwsClientBuilder.EndpointConfiguration) for example: builder.setEndpointConfiguration(new EndpointConfiguration(endpoint, signingRegion));
        Overrides the default endpoint for this client ("elasticloadbalancing.amazonaws.com"). Callers can use this method to control which AWS region they want to work with.

        Callers can pass in just the endpoint (ex: "elasticloadbalancing.amazonaws.com") or a full URL, including the protocol (ex: "elasticloadbalancing.amazonaws.com"). If the protocol is not specified here, the default protocol from this client's ClientConfiguration will be used, which by default is HTTPS.

        For more information on using AWS regions with the AWS SDK for Java, and a complete list of all available endpoints for all AWS services, see: https://docs.aws.amazon.com/sdk-for-java/v1/developer-guide/java-dg-region-selection.html#region-selection- choose-endpoint

        This method is not threadsafe. An endpoint should be configured when the client is created and before any service requests are made. Changing it afterwards creates inevitable race conditions for any service requests in transit or retrying.

        Parameters:
        endpoint - The endpoint (ex: "elasticloadbalancing.amazonaws.com") or a full URL, including the protocol (ex: "elasticloadbalancing.amazonaws.com") of the region specific AWS endpoint this client will communicate with.

      • addTags

        Adds the specified tags to the specified load balancer. Each load balancer can have a maximum of 10 tags.

        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.

        Parameters:
        addTagsRequest - Contains the parameters for AddTags.

      • createAppCookieStickinessPolicy

        CreateAppCookieStickinessPolicyResult createAppCookieStickinessPolicy(CreateAppCookieStickinessPolicyRequest createAppCookieStickinessPolicyRequest)

        Generates a stickiness policy with sticky session lifetimes that follow that of an application-generated cookie. This policy can be associated only with HTTP/HTTPS listeners.

        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.

        Parameters:
        createAppCookieStickinessPolicyRequest - Contains the parameters for CreateAppCookieStickinessPolicy.
        Returns:
        Result of the CreateAppCookieStickinessPolicy operation returned by the service.
        Throws:
        LoadBalancerNotFoundException - The specified load balancer does not exist.

          AmazonElasticLoadBalancing client = AmazonElasticLoadBalancingClientBuilder.standard().build();
CreateAppCookieStickinessPolicyRequest request = new CreateAppCookieStickinessPolicyRequest().withLoadBalancerName("my-load-balancer")
 .withPolicyName("my-app-cookie-policy").withCookieName("my-app-cookie");
CreateAppCookieStickinessPolicyResult response = client.createAppCookieStickinessPolicy(request);

      • createLBCookieStickinessPolicy

        CreateLBCookieStickinessPolicyResult createLBCookieStickinessPolicy(CreateLBCookieStickinessPolicyRequest createLBCookieStickinessPolicyRequest)

        Generates a stickiness policy with sticky session lifetimes controlled by the lifetime of the browser (user-agent) or a specified expiration period. This policy can be associated only with HTTP/HTTPS listeners.

        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.

        Parameters:
        createLBCookieStickinessPolicyRequest - Contains the parameters for CreateLBCookieStickinessPolicy.
        Returns:
        Result of the CreateLBCookieStickinessPolicy operation returned by the service.
        Throws:
        LoadBalancerNotFoundException - The specified load balancer does not exist.
        DuplicatePolicyNameException - A policy with the specified name already exists for this load balancer.
        TooManyPoliciesException - The quota for the number of policies for this load balancer has been reached.
        InvalidConfigurationRequestException - The requested configuration change is not valid.
        See Also:
        AWS API Documentation

        Samples:
        • To generate a duration-based stickiness policy for your load balancer
          This example generates a stickiness policy with sticky session lifetimes controlled by the specified expiration period.

      • registerInstancesWithLoadBalancer

        RegisterInstancesWithLoadBalancerResult registerInstancesWithLoadBalancer(RegisterInstancesWithLoadBalancerRequest registerInstancesWithLoadBalancerRequest)

        Adds the specified instances to the specified load balancer.

        The instance must be a running instance in the same network as the load balancer (EC2-Classic or the same VPC). If you have EC2-Classic instances and a load balancer in a VPC with ClassicLink enabled, you can link the EC2-Classic instances to that VPC and then register the linked EC2-Classic instances with the load balancer in the VPC.

        Note that RegisterInstanceWithLoadBalancer completes when the request has been registered. Instance registration takes a little time to complete. To check the state of the registered instances, use DescribeLoadBalancers or DescribeInstanceHealth.

        After the instance is registered, it starts receiving traffic and requests from the load balancer. Any instance that is not in one of the Availability Zones registered for the load balancer is moved to the OutOfService state. If an Availability Zone is added to the load balancer later, any instances registered with the load balancer move to the InService state.

        To deregister instances from a load balancer, use DeregisterInstancesFromLoadBalancer.

        For more information, see Register or De-Register EC2 Instances in the Classic Load Balancers Guide.

        Parameters:

      • shutdown

        void shutdown()
        Shuts down this client object, releasing any resources that might be held open. This is an optional method, and callers are not expected to call it, but can if they want to explicitly release any open resources. Once a client has been shutdown, it should not be used to make any more requests.

      • getCachedResponseMetadata

        ResponseMetadata getCachedResponseMetadata(AmazonWebServiceRequest request)
        Returns additional metadata for a previously executed successful request, typically used for debugging issues where a service isn't acting as expected. This data isn't considered part of the result data returned by an operation, so it's available through this separate, diagnostic interface.

        Response metadata is only cached for a limited period of time, so if you need to access this extra diagnostic information for an executed request, you should use this method to retrieve it as soon as possible after executing a request.

        Parameters:
        request - The originally executed request.
        Returns:
        The response metadata for the specified request, or null if none is available.
