Study Notes

Cloud Computing and Storage

Cloud storage is a massive pool of data that needs to be organized, and offers various management functions such as user management, security management, replica management, and strategy management.

Characteristics of Cloud Storage

Dramatic reduction in Total Cost of Ownership (TCO), cutting storage cost by more than 10 times compared to block or file storage.
Unlimited scalability, allowing seamless addition or removal of storage systems from the pool.
Elasticity, decoupling and abstracting the storage pool from its physical implementation, providing a virtual, elastic, and unified storage pool.
On-demand model, paying only for the data stored and accessed, resulting in huge cost savings for the storage user.
Universal access, offering flexibility in the number of users and access locations.

Cloud Storage Architecture

Web browser, cloud storage provider, storage server, and HTTP server (which can be load balanced) make up the architecture of a cloud storage platform.
Organization of data involves a user access layer, data service layer, and data management, which provides a unified public management interface for different services.

Object Storage and Data Management

Object storage software takes care of durability models, creating multiple copies of objects and chunking, or creating erasure codes, and supports activities towards management.
Management is made easy by using a single flat namespace, allowing a storage administrator to manage the entire cluster as a single entity.

Amazon Simple Storage Service (S3)

Amazon S3 is a highly reliable, available, scalable, and fast storage in the cloud for storing and retrieving large amounts of data.
Three ways to use S3: through the AWS console (GUI interface), REST-ful API with familiar HTTP operations, or libraries and SDKs for various languages.
S3 browsers allow users to explore their S3 account as if it were a directory or folder.
