Preparation and people key to resiliency

The data storage pioneers at Facebook have recently forced their servers through a worst case scenario in order to improve the company's resiliency preparations. Data Center Knowledge reports that Facebook cut power from one of its regional facilities in order to test how the website's resilience strategy would hold up in an extreme circumstance. In this case, a scenario caused by a widespread power-outage or an electrical storm. The Facebook team also regularly encourages engineers to push the limits of resilience framework and experiment with new solutions.

Invest in personnel resiliency
Accounting for a worst case scenario goes beyond ensuring consistent hardware performance. Companies should also consider how the cause of a facility failure may simultaneously impact the availability of vital personnel. For example, CenturyLink provided housing for data center employees who were put at risk by Hurricane Sandy, according to Forbes. Data center redundancy strategies are only as effective as the employee who implements and manages them. Companies aiming to be 100 percent resilient should account for personnel resiliency as well.
