System and Storage Redundancy

One of the greatest benefits of cloud-based computing is that it does not matter where the physical computing resources and data-storage devices are located. As a result, companies often employ duplicate off-site servers or disk-storage devices through a process known as colocation. As shown in FIGURE 4-10, by employing duplicate resources, systems can failover from one location to another or can use the duplicate systems for load balancing.

A user sends request to a load balancing server which in turn directs the request to server 2 in a larger cloud where server 1 failure is also shown.

FIGURE 4-10 Companies use colocated computing resources for system failover or load balancing.

In this way, the collocated resources
