Overview

Constructs a service interface object. Each API operation is exposed as a function on service.

Service Description

This is the AWS Global Accelerator API Reference. This guide is for developers who need detailed information about AWS Global Accelerator API actions, data types, and errors. For more information about Global Accelerator features, see the AWS Global Accelerator Developer Guide.

AWS Global Accelerator is a network layer service in which you create accelerators to improve availability and performance for internet applications used by a global audience.

Global Accelerator provides you with static IP addresses that you associate with your accelerator. These IP addresses are anycast from the AWS edge network and distribute incoming application traffic across multiple endpoint resources in multiple AWS Regions, which increases the availability of your applications. Endpoints can be Elastic IP addresses, Network Load Balancers, and Application Load Balancers that are located in one AWS Region or multiple Regions.

Global Accelerator uses the AWS global network to route traffic to the optimal regional endpoint based on health, client location, and policies that you configure. The service reacts instantly to changes in health or configuration to ensure that internet traffic from clients is directed to only healthy endpoints.

Global Accelerator includes components that work together to help you improve performance and availability for your applications:

Static IP address

AWS Global Accelerator provides you with a set of static IP addresses which are anycast from the AWS edge network and serve as the single fixed entry points for your clients. If you already have Elastic Load Balancing or Elastic IP address resources set up for your applications, you can easily add those to Global Accelerator to allow the resources to be accessed by a Global Accelerator static IP address.

Accelerator

An accelerator directs traffic to optimal endpoints over the AWS global network to improve availability and performance for your internet applications that have a global audience. Each accelerator includes one or more listeners.

Network zone

A network zone services the static IP addresses for your accelerator from a unique IP subnet. Similar to an AWS Availability Zone, a network zone is an isolated unit with its own set of physical infrastructure. When you configure an accelerator, Global Accelerator allocates two IPv4 addresses for it. If one IP address from a network zone becomes unavailable due to IP address blocking by certain client networks, or network disruptions, then client applications can retry on the healthy static IP address from the other isolated network zone.

Listener

A listener processes inbound connections from clients to Global Accelerator, based on the protocol and port that you configure. Each listener has one or more endpoint groups associated with it, and traffic is forwarded to endpoints in one of the groups. You associate endpoint groups with listeners by specifying the Regions that you want to distribute traffic to. Traffic is distributed to optimal endpoints within the endpoint groups associated with a listener.

Endpoint group

Each endpoint group is associated with a specific AWS Region. Endpoint groups include one or more endpoints in the Region. You can increase or reduce the percentage of traffic that would be otherwise directed to an endpoint group by adjusting a setting called a traffic dial. The traffic dial lets you easily do performance testing or blue/green deployment testing for new releases across different AWS Regions, for example.

Endpoint

An endpoint is an Elastic IP address, Network Load Balancer, or Application Load Balancer. Traffic is routed to endpoints based on several factors, including the geo-proximity to the user, the health of the endpoint, and the configuration options that you choose, such as endpoint weights. For each endpoint, you can configure weights, which are numbers that you can use to specify the proportion of traffic to route to each one. This can be useful, for example, to do performance testing within a Region.

Sending a Request Using GlobalAccelerator

var globalaccelerator = new AWS.GlobalAccelerator();
globalaccelerator.createAccelerator(params, function (err, data) {
  if (err) console.log(err, err.stack); // an error occurred
  else     console.log(data);           // successful response
});

Locking the API Version

In order to ensure that the GlobalAccelerator object uses this specific API, you can construct the object by passing the apiVersion option to the constructor:

var globalaccelerator = new AWS.GlobalAccelerator({apiVersion: '2018-08-08'});

You can also set the API version globally in AWS.config.apiVersions using the globalaccelerator service identifier:

AWS.config.apiVersions = {
  globalaccelerator: '2018-08-08',
  // other service API versions
};

var globalaccelerator = new AWS.GlobalAccelerator();

createListener(params = {}, callback) ⇒ AWS.Request

Create a listener to process inbound connections from clients to an accelerator. Connections arrive to assigned static IP addresses on a port, port range, or list of port ranges that you specify. To see an AWS CLI example of creating a listener, scroll down to Example.

Service Reference:

Examples:

Calling the createListener operation

var params = {
  AcceleratorArn: 'STRING_VALUE', /* required */
  IdempotencyToken: 'STRING_VALUE', /* required */
  PortRanges: [ /* required */
    {
      FromPort: 'NUMBER_VALUE',
      ToPort: 'NUMBER_VALUE'
    },
    /* more items */
  ],
  Protocol: TCP | UDP, /* required */
  ClientAffinity: NONE | SOURCE_IP
};
globalaccelerator.createListener(params, function(err, data) {
  if (err) console.log(err, err.stack); // an error occurred
  else     console.log(data);           // successful response
});

Parameters:

  • params (Object) (defaults to: {}) —
    • AcceleratorArn — (String)

      The Amazon Resource Name (ARN) of your accelerator.

    • PortRanges — (Array<map>)

      The list of port ranges to support for connections from clients to your accelerator.

      • FromPort — (Integer)

        The first port in the range of ports, inclusive.

      • ToPort — (Integer)

        The last port in the range of ports, inclusive.

    • Protocol — (String)

      The protocol for connections from clients to your accelerator.

      Possible values include:
      • "TCP"
      • "UDP"
    • ClientAffinity — (String)

      Client affinity lets you direct all requests from a user to the same endpoint, if you have stateful applications, regardless of the port and protocol of the client request. Clienty affinity gives you control over whether to always route each client to the same specific endpoint.

      AWS Global Accelerator uses a consistent-flow hashing algorithm to choose the optimal endpoint for a connection. If client affinity is NONE, Global Accelerator uses the "five-tuple" (5-tuple) properties—source IP address, source port, destination IP address, destination port, and protocol—to select the hash value, and then chooses the best endpoint. However, with this setting, if someone uses different ports to connect to Global Accelerator, their connections might not be always routed to the same endpoint because the hash value changes.

      If you want a given client to always be routed to the same endpoint, set client affinity to SOURCE_IP instead. When you use the SOURCE_IP setting, Global Accelerator uses the "two-tuple" (2-tuple) properties— source (client) IP address and destination IP address—to select the hash value.

      The default value is NONE.

      Possible values include:
      • "NONE"
      • "SOURCE_IP"
    • IdempotencyToken — (String)

      A unique, case-sensitive identifier that you provide to ensure the idempotency—that is, the uniqueness—of the request.

Callback (callback):

  • function(err, data) { ... }

    Called when a response from the service is returned. If a callback is not supplied, you must call AWS.Request.send() on the returned request object to initiate the request.

    Context (this):

          • FromPort — (Integer)

            The first port in the range of ports, inclusive.

          • ToPort — (Integer)

            The last port in the range of ports, inclusive.

        • Protocol — (String)

          The protocol for the connections from clients to the accelerator.

          Possible values include:
          • "TCP"
          • "UDP"
        • ClientAffinity — (String)

          Client affinity lets you direct all requests from a user to the same endpoint, if you have stateful applications, regardless of the port and protocol of the client request. Clienty affinity gives you control over whether to always route each client to the same specific endpoint.

          AWS Global Accelerator uses a consistent-flow hashing algorithm to choose the optimal endpoint for a connection. If client affinity is NONE, Global Accelerator uses the "five-tuple" (5-tuple) properties—source IP address, source port, destination IP address, destination port, and protocol—to select the hash value, and then chooses the best endpoint. However, with this setting, if someone uses different ports to connect to Global Accelerator, their connections might not be always routed to the same endpoint because the hash value changes.

          If you want a given client to always be routed to the same endpoint, set client affinity to SOURCE_IP instead. When you use the SOURCE_IP setting, Global Accelerator uses the "two-tuple" (2-tuple) properties— source (client) IP address and destination IP address—to select the hash value.

          The default value is NONE.

          Possible values include:
          • "NONE"
          • "SOURCE_IP"

Returns:

  • (AWS.Request) —

    a handle to the operation request for subsequent event callback registration.

            • Timeout: The health check requests to the endpoint are timing out before returning a status.

            • Failed: The health check failed, for example because the endpoint response was invalid (malformed).

            If the endpoint state is initial, the reason code can be one of the following values:

            • ProvisioningInProgress: The endpoint is in the process of being provisioned.

        • HealthCheckPort — (Integer)

          The port that Global Accelerator uses to perform health checks on endpoints that are part of this endpoint group.

        • HealthCheckIntervalSeconds — (Integer)

          The time—10 seconds or 30 seconds—between health checks for each endpoint. The default value is 30.

        • ThresholdCount — (Integer)

          The number of consecutive health checks required to set the state of a healthy endpoint to unhealthy, or to set an unhealthy endpoint to healthy. The default value is 3.

            The reason code associated with why the endpoint is not healthy. If the endpoint state is healthy, a reason code is not provided.

            If the endpoint state is unhealthy, the reason code can be one of the following values:

            • Timeout: The health check requests to the endpoint are timing out before returning a status.

            • Failed: The health check failed, for example because the endpoint response was invalid (malformed).

            If the endpoint state is initial, the reason code can be one of the following values:

            • ProvisioningInProgress: The endpoint is in the process of being provisioned.

            • InitialHealthChecking: Global Accelerator is still setting up the minimum number of health checks for the endpoint that are required to determine its health status.

        • TrafficDialPercentage — (Float)

          The percentage of traffic to send to an AWS Region. Additional traffic is distributed to other endpoint groups for this listener.

          Use this action to increase (dial up) or decrease (dial down) traffic to a specific Region. The percentage is applied to the traffic that would otherwise have been routed to the Region based on optimal routing.

          The default value is 100.

        • HealthCheckPort — (Integer)

          The port that Global Accelerator uses to perform health checks on endpoints that are part of this endpoint group.

          The default port is the port for the listener that this endpoint group is associated with. If the listener port is a list, Global Accelerator uses the first specified port in the list of ports.

        • HealthCheckProtocol — (String)

        • HealthCheckIntervalSeconds — (Integer)

          The time—10 seconds or 30 seconds—between health checks for each endpoint. The default value is 30.

        • ThresholdCount — (Integer)

          The number of consecutive health checks required to set the state of a healthy endpoint to unhealthy, or to set an unhealthy endpoint to healthy. The default value is 3.

Returns:

  • (AWS.Request) —

    a handle to the operation request for subsequent event callback registration.

listListeners(params = {}, callback) ⇒ AWS.Request

List the listeners for an accelerator.

Service Reference:

Examples:

Calling the listListeners operation

var params = {
  AcceleratorArn: 'STRING_VALUE', /* required */
  MaxResults: 'NUMBER_VALUE',
  NextToken: 'STRING_VALUE'
};
globalaccelerator.listListeners(params, function(err, data) {
  if (err) console.log(err, err.stack); // an error occurred
  else     console.log(data);           // successful response
});

Parameters:

  • params (Object) (defaults to: {}) —
    • AcceleratorArn — (String)

      The Amazon Resource Name (ARN) of the accelerator for which you want to list listener objects.

    • MaxResults — (Integer)

      The number of listener objects that you want to return with this call. The default value is 10.

    • NextToken — (String)

      The token for the next set of results. You receive this token from a previous call.

Callback (callback):

  • function(err, data) { ... }

    Called when a response from the service is returned. If a callback is not supplied, you must call AWS.Request.send() on the returned request object to initiate the request.

    Context (this):

    • (AWS.Response) —

      the response object containing error, data properties, and the original request object.

    Parameters:

    • err (Error) —

      the error object returned from the request. Set to null if the request is successful.

    • data (Object) —

      the de-serialized data returned from the request. Set to null if a request error occurs. The data object has the following properties:

      • Listeners — (Array<map>)

        The list of listeners for an accelerator.

        • ListenerArn — (String)

          The Amazon Resource Name (ARN) of the listener.

        • PortRanges — (Array<map>)

          The list of port ranges for the connections from clients to the accelerator.

          • FromPort — (Integer)

            The first port in the range of ports, inclusive.

          • ToPort — (Integer)

            The last port in the range of ports, inclusive.

        • Protocol — (String)

          The protocol for the connections from clients to the accelerator.

          Possible values include:
          • "TCP"

        • ClientAffinity — (String)

          Client affinity lets you direct all requests from a user to the same endpoint, if you have stateful applications, regardless of the port and protocol of the client request. Clienty affinity gives you control over whether to always route each client to the same specific endpoint.

          AWS Global Accelerator uses a consistent-flow hashing algorithm to choose the optimal endpoint for a connection. If client affinity is NONE, Global Accelerator uses the "five-tuple" (5-tuple) properties—source IP address, source port, destination IP address, destination port, and protocol—to select the hash value, and then chooses the best endpoint. However, with this setting, if someone uses different ports to connect to Global Accelerator, their connections might not be always routed to the same endpoint because the hash value changes.

          If you want a given client to always be routed to the same endpoint, set client affinity to SOURCE_IP instead. When you use the SOURCE_IP setting, Global Accelerator uses the "two-tuple" (2-tuple) properties— source (client) IP address and destination IP address—to select the hash value.

          The default value is NONE.

          Possible values include:
          • "NONE"
          • "SOURCE_IP"
      • NextToken — (String)

        The token for the next set of results. You receive this token from a previous call.
