// Amazon Glacier is a storage solution for "cold data."
//
// Amazon Glacier is an extremely low-cost storage service that provides secure,
// durable, and easy-to-use storage for data backup and archival. With Amazon
// Glacier, customers can store their data cost effectively for months, years,
// or decades. Amazon Glacier also enables customers to offload the administrative
// burdens of operating and scaling storage to AWS, so they don't have to worry
// about capacity planning, hardware provisioning, data replication, hardware
// failure and recovery, or time-consuming hardware migrations.
//
// Amazon Glacier is a great storage choice when low storage cost is paramount,
// your data is rarely retrieved, and retrieval latency of several hours is
// acceptable. If your application requires fast or frequent access to your
// data, consider using Amazon S3. For more information, go to Amazon Simple
// Storage Service (Amazon S3) (http://aws.amazon.com/s3/).
//
// You can store any kind of data in any format. There is no maximum limit
// on the total amount of data you can store in Amazon Glacier.
//
// If you are a first-time user of Amazon Glacier, we recommend that you begin
// by reading the following sections in the Amazon Glacier Developer Guide:
//
//  What is Amazon Glacier (http://docs.aws.amazon.com/amazonglacier/latest/dev/introduction.html)
// - This section of the Developer Guide describes the underlying data model,
// the operations it supports, and the AWS SDKs that you can use to interact
// with the service.
//
// Getting Started with Amazon Glacier (http://docs.aws.amazon.com/amazonglacier/latest/dev/amazon-glacier-getting-started.html)
// - The Getting Started section walks you through the process of creating a
// vault, uploading archives, creating jobs to download archives, retrieving
// the job output, and deleting archives.
//The service client's operations are safe to be used concurrently.
// It is not safe to mutate any of the client's properties though.
