Elastic Block Store.

This is a virtual disk, but it’s a type of disk suited to reading and writing in “blocks”. Databases tend to use this sort of storage type, as it has a much faster read & write speed.

In this sense, “Elastic” is not that far from an elastic band. The capacity of your resources can stretch and shrink to meet demand, within limits. Compute is running apps, although in this case, it refers to virtual servers or virtual machines (VMs).

Basically a network drive. Cool pricing model — you just use it and pay for what you use. Unlike disk-based storage pricing, such as EBS, where you have to provision and pay for a whole disk. One less headache.

A method used to convert data (in the form of passwords, files, or emails) into an illegible format if intercepted or accessed without the correct Encryption Key. The Key is a pass phrase set by the user encrypting the data before it is stored/sent online, with the encryption software performing complex mathematical operations on the data. 

Allow multiple devices/servers to access a form of Direct/Network-attached storage, by keeping the RAID controller external from any one particular server. This means that if the server goes offline others will still be able to access the storage.
