Data center availability and reliability have accomplished greater concern due to increased dependence on Internet services (e.g., Cloud computing paradigm, social networks and e-commerce). For companies that heavily depend on the Internet for their operations, service outages can be very expensive, easily running into millions of dollars per hour [15]. A widely used design principle in fault-tolerance is to introduce redundancy to enhance availability. However, since redundancy leads to additional use of resources and energy, it is expected to have a negative impact on sustainability and the associated cost.
