/**
* AWS Global Accelerator
*
* 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.
