This module provides a Perlish interface to Amazon S3. From the developer blurb: "Amazon S3 is storage for the Internet. It is designed to make web-scale computing easier for developers. Amazon S3 provides a simple web services interface that can be used to store and retrieve any amount of data, at any time, from anywhere on the web. It gives any developer access to the same highly scalable, reliable, fast, inexpensive data storage infrastructure that Amazon uses to run its own global network of web sites. The service aims to maximize benefits of scale and to pass those benefits on to developers".
To find out more about S3, please visit: http://s3.amazonaws.com/
To use this module you will need to sign up to Amazon Web Services and provide an "Access Key ID" and " Secret Access Key". If you use this module, you will incurr costs as specified by Amazon. Please check the costs. If you use this module with your Access Key ID and Secret Access Key you must be responsible for these costs.
I highly recommend reading all about S3, but in a nutshell data is stored in values. Values are referenced by keys, and keys are stored in buckets. Bucket names are global.
Note: This is the legacy interface, please check out Net::Amazon::S3::Client instead.
Development of this code happens here: https://github.com/rustyconover/net-amazon-s3
Create a new S3 client object. Takes some arguments:
DO NOT INCLUDE THIS IN SCRIPTS OR APPLICATIONS YOU DISTRIBUTE. YOU'LL BE SORRY
To use SSL-encrypted connections, LWP::Protocol::https is required.
This library provides Net::Amazon::S3::Signature::V2 and Net::Amazon::S3::Signature::V4
Default is Signature 4 if host is "s3.amazonaws.com", Signature 2 otherwise
Notes
When using Net::Amazon::S3 in child processes using fork (such as in combination with the excellent Parallel::ForkManager) you should create the S3 object in each child, use a fresh LWP::UserAgent in each child, or disable the LWP::ConnCache in the parent:
$s3->ua( LWP::UserAgent->new(
keep_alive => 0, requests_redirectable => [qw'GET HEAD DELETE PUT POST'] );
Returns undef on error, else hashref of results
Takes a hashref:
Returns 0 on failure, Net::Amazon::S3::Bucket object on success
Takes a scalar argument, the name of the bucket you're creating
Returns an (unverified) bucket object from an account. Does no network access.
Takes either a Net::Amazon::S3::Bucket object or a hashref containing
Returns false (and fails) if the bucket isn't empty.
Returns true if the bucket is successfully deleted.
List all keys in this bucket.
Takes a hashref of arguments:
MANDATORY
OPTIONAL
Each element in the CommonPrefixes collection counts as one against the MaxKeys limit. The rolled-up keys represented by each CommonPrefixes element do not. If the Delimiter parameter is not present in your request, keys in the result set will not be rolled-up and neither the CommonPrefixes collection nor the NextMarker element will be present in the response.
See also "next_marker", below.
If "marker" is omitted,the first page of results is returned.
Returns undef on error and a hashref of data on success:
The hashref looks like this:
{
bucket => $bucket_name,
prefix => $bucket_prefix,
common_prefixes => [$prefix1,$prefix2,...]
marker => $bucket_marker,
next_marker => $bucket_next_available_marker,
max_keys => $bucket_max_keys,
is_truncated => $bucket_is_truncated_boolean
keys => [$key1,$key2,...]
}
Explanation of bits of that:
Each key is a hashref that looks like this:
{
key => $key,
last_modified => $last_mod_date,
etag => $etag, # An MD5 sum of the stored content.
size => $size, # Bytes
storage_class => $storage_class # Doc?
owner_id => $owner_id,
owner_displayname => $owner_name
}
List all keys in this bucket without having to worry about 'marker'. This is a convenience method, but may make multiple requests to S3 under the hood.
Takes the same arguments as list_bucket.

Testing S3 is a tricky thing. Amazon wants to charge you a bit of money each time you use their service. And yes, testing counts as using. Because of this, the application's test suite skips anything approaching a real test unless you set these three environment variables:
Leon Brocard <acme@astray.com> and unknown Amazon Digital Services programmers.
Brad Fitzpatrick <brad@danga.com> - return values, Bucket object
Pedro Figueiredo <me@pedrofigueiredo.org> - since 0.54
Net::Amazon::S3::Bucket
