Terminology Used in Amazon S3 

Objects 

Objects are the basic contents stored in Amazon S3. Each object has object data and meta data. Object data is the original data and the meta data describes the name value of the object. Meta data includes the default value, modified data and Http meta values. We can also customize the meta while storing the object.

Buckets

A bucket is a container of objects. Every object stored in Amazon S3 is contained in a bucket. Buckets will help to organize the objects, identify the account responsible for storage and data transfer, access restrictions using ACL and easy to pull reports. Every object inside the buckets is identified by a key and unique version ID.

Regions

We can choose to create the Amazon S3 buckets in any of the available across the globe.

                                   

Objects stored in one region can be transferred to other regions.

● ACL (Access Control List)

In Amazon S3, Access Control List provides privileges to the buckets and objects. Each objects or buckets is associated with ACL and that defines the access to aws accounts and the type of privileges.

When an object is created, ACL offers full control to the owner of the resource. In ACL Grant is an element that identifies the ‘grantee’ (it may be a aws account or predefined group of users) and it is permission. The permission list are as follows, READ, WRITE, READ_ACP, WRITE_ACP and FULL_CONTROL.

In ACL, there are predefined grants available which are called Canned ACLs. The permission list are as follows, private, public-read, public-read-write, authenticated-read, bucket-owner-read, bucket-owner-full-control, log-delivery-write.

How to Setup and Manage S3?
