[Cloud Computing]Patterns: Cross-Storage Device Vertical Tiering

Cross-Storage Device Vertical Tiering (Erl, Naserpour)

How can the vertical scaling of data processing be carried out dynamically?

Problem

Increasing the processing capacity of data stored on cloud storage devices generally requires the manual vertical scaling of the device, which is inefficient and potentially wasteful.

Solution

A system is established whereby the vertical scaling of data processing can be carried out dynamically across multiple cloud storage devices.

Application

Using pre-defined capacity thresholds, LUN migration is used to dynamically move LUN disks between cloud storage devices with different capacities.
