// AWS Storage Gateway is the service that connects an on-premises software
// appliance with cloud-based storage to provide seamless and secure integration
// between an organization's on-premises IT environment and AWS's storage infrastructure.
// The service enables you to securely upload data to the AWS cloud for cost
// effective backup and rapid disaster recovery.
//
// Use the following links to get started using the AWS Storage Gateway Service
// API Reference:
//
//    * AWS Storage Gateway Required Request Headers (http://docs.aws.amazon.com/storagegateway/latest/userguide/AWSStorageGatewayAPI.html#AWSStorageGatewayHTTPRequestsHeaders):
//    Describes the required headers that you must send with every POST request
//    to AWS Storage Gateway.
//
//    * Signing Requests (http://docs.aws.amazon.com/storagegateway/latest/userguide/AWSStorageGatewayAPI.html#AWSStorageGatewaySigningRequests):
//    AWS Storage Gateway requires that you authenticate every request you send;
//    this topic describes how sign such a request.
//
//    * Error Responses (http://docs.aws.amazon.com/storagegateway/latest/userguide/AWSStorageGatewayAPI.html#APIErrorResponses):
//    Provides reference information about AWS Storage Gateway errors.
//
//    * Operations in AWS Storage Gateway (http://docs.aws.amazon.com/storagegateway/latest/APIReference/API_Operations.html):
//    Contains detailed descriptions of all AWS Storage Gateway operations,
//    their request parameters, response elements, possible errors, and examples
//    of requests and responses.
//
//    * AWS Storage Gateway Regions and Endpoints (http://docs.aws.amazon.com/general/latest/gr/index.html?rande.html):
//    Provides a list of each of the s and endpoints available for use with
//    AWS Storage Gateway.
//
// AWS Storage Gateway resource IDs are in uppercase. When you use these resource
// IDs with the Amazon EC2 API, EC2 expects resource IDs in lowercase. You must
// change your resource ID to lowercase to use it with the EC2 API. For example,
// in Storage Gateway the ID for a volume might be vol-1122AABB. When you use
// this ID with the EC2 API, you must change it to vol-1122aabb. Otherwise,
// the EC2 API might not behave as expected.
//
// IDs for Storage Gateway volumes and Amazon EBS snapshots created from gateway
// volumes are changing to a longer format. Starting in December 2016, all new
// volumes and snapshots will be created with a 17-character string. Starting
// in April 2016, you will be able to use these longer IDs so you can test your
// systems with the new format. For more information, see Longer EC2 and EBS
// Resource IDs (https://aws.amazon.com/ec2/faqs/#longer-ids).
//
//  For example, a volume ARN with the longer volume ID format will look like
// this:
//
// arn:aws:storagegateway:us-west-2:111122223333:gateway/sgw-12A3456B/volume/vol-1122AABBCCDDEEFFG.
//
// A snapshot ID with the longer ID format will look like this: snap-78e226633445566ee.
//
// For more information, see Announcement: Heads-up – Longer AWS Storage Gateway
// volume and snapshot IDs coming in 2016 (https://forums.aws.amazon.com/ann.jspa?annID=3557).
// The service client's operations are safe to be used concurrently.
// It is not safe to mutate any of the client's properties though.
// Please also see https://docs.aws.amazon.com/goto/WebAPI/storagegateway-2013-06-30
