You can then download the data * or use the data with other AWS services, such as Amazon Elastic Cloud Computer (EC2). * * Amazon Simple Storage Service (Amazon S3) is storage for the Internet. You can use Amazon S3 to store * and retrieve any amount of data at any time, from anywhere on the web. You can accomplish these tasks * using the AWS Management Console, which is a simple and intuitive web interface. * * To get the most out of Amazon S3, you need to understand a few simple concepts. Amazon S3 stores data * as objects in buckets. An object is comprised of a file and optionally any metadata that describes * that file. * * To store an object in Amazon S3, you upload the file you want to store to a bucket. When you upload a * file, you can set permissions on the object as well as any metadata. * * Buckets are the containers for objects. You can have one or more buckets. For each bucket, you can control * access to the bucket (who can create, delete, and list objects in the bucket), view access logs for the * bucket and its objects, and choose the geographical region where Amazon S3 will store the bucket and its * contents. * * Visit <http://aws.amazon.com/s3/> for more information. * * @version 2012.08.28 * @license See the included NOTICE.md file for more information. * @copyright See the included NOTICE.md file for more information. * @link http://aws.amazon.com/s3/ Amazon Simple Storage Service * @link http://aws.amazon.com/documentation/s3/ Amazon Simple Storage Service documentation / class AmazonS3 extends CFRuntime { /%*****************************************************************************************%/ // REGIONAL ENDPOINTS /** * Specify the queue URL for the US-Standard (Northern Virginia & Washington State) Region. / const REGION_US_E1 = 's3.amazonaws.com';
