Amazon Simple Storage Service (s3)
Amazon
S3 is storage for the Internet. It is designed to make web-scale
computing easier for developers. Its is used for storing the database
and dumps in the cloud. Its like a external hard disk in the cloud
where you can upload the data and download the data when ever needed.
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, secure, fast, inexpensive 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.
Amazon S3 Functionality:
Amazon
S3 is intentionally built with a minimal feature set.
Write,
read, and delete objects containing from 1 byte to 5 terabytes of
data each. The number of objects you can store is unlimited
Options
for secure data upload/download and encryption of data at rest are
provided for additional data protection.
Uses
standards-based REST and SOAP interfaces designed to work with any
Internet-development toolkit.
Data
Security Details:
Amazon
S3 supports several mechanisms that give you flexibility to control
who can access your data as well as how, when, and where they can
access it. Amazon S3 provides four different access control
mechanisms: Identity and Access Management (IAM) policies, Access
Control Lists (ACLs), bucket policies, and query string
authentication. IAM enables organizations with multiple employees to
create and manage multiple users under a single AWS account. With IAM
policies, you can grant IAM users fine-grained control to your Amazon
S3 bucket or objects. You can use ACLs to selectively add (grant)
certain permissions on individual objects. Amazon S3 Bucket Policies
can be used to add or deny permissions across some or all of the
objects within a single bucket. With Query string authentication, you
have the ability to share Amazon S3 objects through URLs that are
valid for a predefined expiration time
Amazon
S3’s standard storage is:
- Designed to provide 99.999999999% durability and 99.99% availability of objects over a given year.
- Designed to sustain the concurrent loss of data in two facilities.
