A Survey on Performance and Energy Management in Cloud Computing

Cloud computing is the latest distributed computing paradigm and it offers tremendous opportunities to solve large-scale scientific problems. Energy awareness and real time service management are big challenges in cloud datacenter. Reducing Energy consumption has been an essential technique for Cloud resources and data centers not only to decrease operating costs, but also to improve the system reliability. Many techniques such as Scheduling, live migration, and resource allocation have been proposed to reduce energy consumption. Concepts like DVFS, Dynamic MIPS adjustment and live migration contributed to reduction in energy consumption. Several schemes reduce power consumption by real-time services, and suggest power-aware profitable provisioning of real-time services.
