Summary
To satisfy operational demands, customers increasingly require data and applications be available around the clock. Commonly, availability is viewed as the single most important metric of overall system performance.
With the increasing reliance on computer systems and wider accessibility of e-commerce, availability is no longer a pre-requisite of just mission-critical applications, but of the whole IT infrastructure.
Availability is affected by hardware and software, and more importantly, by people and processes. Availability can be optimized by implementing a systematic approach to applying best practices in the datacenter, which could assist in minimizing the impact of human error.
