AmazonS3 Class

Properties Methods Events Configuration Settings Errors

The S3 Component provides an easy interface to Amazon's Simple Storage Service (S3).

Syntax

AmazonS3

Remarks

The S3 Class allows you to access Amazon's Simple Storage Service (S3) in a secure manner using TLS/SSL. S3 allows you to store arbitrary data objects on Amazon's server and access them from anywhere using an Internet connection. There are features available to authenticate access to private objects, share objects as public, distribute an object using Bittorrent etc. A brief synopsis follows but please refer to Amazon S3 documentation for details.

You will first need to sign up for the S3 service and obtain the AccessKey and SecretKey from Amazon. Then you can start creating buckets in your account using CreateBucket. The buckets are place holders for your objects allowing you to access them by http URLs. You can then add objects to any of your buckets using CreateObject.

There are other methods such as ListBuckets, ListObjects, GetObject, GetLink, DeleteObject etc. that further enable you to manage your S3 data store.
