## Description
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
<http://aws.amazon.com/s3/ Amazon Simple Storage Service (Amazon 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/:
- <http://docs.aws.amazon.com/amazonglacier/latest/dev/introduction.html What is Amazon Glacier>
- 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.
- <http://docs.aws.amazon.com/amazonglacier/latest/dev/amazon-glacier-getting-started.html Getting Started with Amazon Glacier>
- 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.
Documentation is available via [Hackage](http://hackage.haskell.org/package/amazonka-glacier)
and the [AWS API Reference](http://docs.aws.amazon.com/amazonglacier/latest/dev/introduction.html).
The types from this library are intended to be used with [amazonka](http://hackage.haskell.org/package/amazonka),
which provides mechanisms for specifying AuthN/AuthZ information and sending requests.
Use of lenses is required for constructing and manipulating types.
This is due to the amount of nesting of AWS types and transparency regarding
de/serialisation into more palatable Haskell values.
The provided lenses should be compatible with any of the major lens libraries
[lens](http://hackage.haskell.org/package/lens) or [lens-family-core](http://hackage.haskell.org/package/lens-family-core).
