Glossary
A method that enables a client to see if a server can accept a request before actually
sending it. For large PUTs, this can save both time and bandwidth
charges.
AWS account associated with a particular developer.
The process of proving your identity to the system.
A container for objects stored in Amazon S3. Every object is contained within a bucket. For
example, if the object named photos/puppy.jpg is stored in the
johnsmith bucket, then it is addressable using the URL
http://johnsmith.s3.amazonaws.com/photos/puppy.jpg
A standard access control policy that you can apply to a bucket or object. Valid Values: private | public-read | public-read-write | authenticated-read | bucket-owner-read | bucket-owner-full-control
The process of converting data into a standard format that will be recognized by a service such as Amazon S3.
The method through which Amazon S3 achieves high availability, which involves replicating data across multiple servers within Amazon's data centers. After a "success" is returned, your data is safely stored. However, information about the changes might not immediately replicate across Amazon S3.
The unique identifier for an object within a bucket. Every object in a bucket has exactly one key. Since a bucket and key together uniquely identify each object, Amazon S3 can be thought of as a basic data map between "bucket + key" and the object itself. Every object in Amazon S3 can be uniquely addressed through the combination of the web service endpoint, bucket name, and key, as in http://doc.s3.amazonaws.com/2006-03-01/AmazonS3.wsdl, where "doc" is the name of the bucket, and "2006-03-01/AmazonS3.wsdl" is the key.
The metadata is a set of name-value pairs that describe the object. These include default metadata such as the date last modified and standard HTTP metadata such as Content-Type. The developer can also specify custom metadata at the time the Object is stored.
The fundamental entities stored in Amazon S3. Objects consist of object data and metadata. The data portion is opaque to Amazon S3.
The host and port with which you are trying to communicate within the destination URL.
For virtual hosted-style requests, this is mybucket.s3.amazonaws.com. For
path-style requests, this is s3.amazonaws.com
