Redundant Storage (Erl, Naserpour)

How can the reliability and availability of cloud storage devices survive failure conditions?

Redundant Storage

Problem

When cloud storage devices fail or become inaccessible, cloud consumers are unable to access data and cloud services relying on access to the device may also fail.

Solution

A failsafe system comprised of redundant cloud storage devices is established so that when the primary device fails, the redundant secondary device takes its place.

Application

Data is replicated from the primary storage to the secondary storage device. A storage service gateway is used to redirect data access requests to the secondary storage device, when necessary.
