/**
* Global Accelerator
*
* This is the Global Accelerator API Reference. This guide is for developers who need detailed information about
* Global Accelerator API actions, data types, and errors. For more information about Global Accelerator features, see
* the Global
* Accelerator Developer Guide.
*
*
* Global Accelerator is a service in which you create accelerators to improve the performance of your
* applications for local and global users. Depending on the type of accelerator you choose, you can gain additional
* benefits.
*
*
* -
*
* By using a standard accelerator, you can improve availability of your internet applications that are used by a global
* audience. With a standard accelerator, Global Accelerator directs traffic to optimal endpoints over the Amazon Web
* Services global network.
*
*
* -
*
* For other scenarios, you might choose a custom routing accelerator. With a custom routing accelerator, you can use
* application logic to directly map one or more users to a specific endpoint among many endpoints.
*
*
*
*
*
* Global Accelerator is a global service that supports endpoints in multiple Amazon Web Services Regions but you must
* specify the US West (Oregon) Region to create, update, or otherwise work with accelerators. That is, for example,
* specify --region us-west-2 on Amazon Web Services CLI commands.
*
*
*
* By default, Global Accelerator provides you with static IP addresses that you associate with your accelerator. The
* static IP addresses are anycast from the Amazon Web Services edge network. For IPv4, Global Accelerator provides two
* static IPv4 addresses. For dual-stack, Global Accelerator provides a total of four addresses: two static IPv4
* addresses and two static IPv6 addresses. With a standard accelerator for IPv4, instead of using the addresses that
* Global Accelerator provides, you can configure these entry points to be IPv4 addresses from your own IP address
* ranges that you bring to Global Accelerator (BYOIP).
*
*
* For a standard accelerator, they distribute incoming application traffic across multiple endpoint resources in
* multiple Amazon Web Services Regions , which increases the availability of your applications. Endpoints for standard
* accelerators can be Network Load Balancers, Application Load Balancers, Amazon EC2 instances, or Elastic IP addresses
* that are located in one Amazon Web Services Region or multiple Amazon Web Services Regions. For custom routing
* accelerators, you map traffic that arrives to the static IP addresses to specific Amazon EC2 servers in endpoints
* that are virtual private cloud (VPC) subnets.
*
*
*
* The static IP addresses remain assigned to your accelerator for as long as it exists, even if you disable the
* accelerator and it no longer accepts or routes traffic. However, when you delete an accelerator, you lose the
* static IP addresses that are assigned to it, so you can no longer route traffic by using them. You can use IAM
* policies like tag-based permissions with Global Accelerator to limit the users who have permissions to delete an
* accelerator. For more information, see Tag-based policies.
*
*
*
* For standard accelerators, Global Accelerator uses the Amazon Web Services 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 always directed to
* healthy endpoints.
*
*
* For more information about understanding and using Global Accelerator, see the Global Accelerator
* Developer Guide.
