It’s got 3 S’s, so S3. This is an object store, rather than a file store. It’s interchangeable with file storage to an extent. But instead of using native OS commands, you interact with it using the AWS CLI tool.

S3 also has the ability to run static websites (so no server-side content, sorry PHP devs), and in combination with CloudFront (I’ll talk about that later) can publish your content globally, with extremely low latency.

A high-speed special-purpose network (or sub network) that can interconnect various kinds of data storage devices (usually disks) with associated data servers. This can be useful when providing storage to of a larger network of Users, where the requirements of each server can vary dynamically.

New technology replacing SCSI connectors and using SCSI protocol. 

Scale-out network-attached storage (NAS) addresses the explosive growth of structured and unstructured data, and performance demands of today’s workloads. A scale-out storage architecture takes advantage of the superior price and performance of clustered components, facilitates nondisruptive operations, and employs policy-based management for improved efficiency and agility.

A set of standards allowing computers to communicate with attached devices, such as storage devices (disk drives, tape libraries etc) and printers. SCSI also refers to a parallel interconnect technology that implements the SCSI protocol.

A cloud computing execution model in which the cloud provider runs the server, and dynamically manages the allocation of machine resources. The pricing is based on the actual amount of resource consumed by an application, rather than on pre-purchased units of capacity.

A term coined by Microsoft. A “Shadow Copy” is a point–in–time copy of the original data and is often possible when the data is in use.

A subsystem that houses a group of disks together controlled by software usually housed within the subsystem.

The amount of data a server is able to store. It is usually measured in Megabytes (MB), Gigabytes (GB) Terabytes (TB).

Providing such functionality as disk aggregation (RAID), I/O routing, and error detection and recovery, the controller provides the intelligence for the storage subsystem. Each storage subsystem contains one or more storage controllers.
