Allocation strategies of virtual machine for cloud Environment: A review

Cloud computing is the most integral part of todays world of computing. It provides various advantageous like reliability, economical, pay as you use, on demand service. Cloud hides the ambiguity of different hardware through virtualization technology. Virtualization is the foundation of cloud, it provides Infrastructure as a Service (IaaS), Software as a Service (SaaS) and Platform as a Service (PaaS). As cloud infrastructure heavily relies on virtualization technology, so there is a requirement of an absolute virtual machine allocation method. Resource allocation is most emerging research area in cloud environment. This has led to a new area in the literature dealing with the issue of assigning virtual machines with variable demands to physical servers in such a way that performance is enhanced and system becames more scalable. Cloud providers faces a huge problem of designing effective mechanisms for virtual machine (VM) allocation and their provisioning. Good mechanisms is helpful for cloud service providers to effectively use their existing resources and achieve higher productivity and profit. By using different approaches like performance, energy, cost in allocating resources make it easier and improves the scheduling of virtual machines. This survey explore the various virtual machine allocation paradigm.
