SLA_Driven Adaptive Resource Allocation for Virtualized Servers
In order to reduce cost and improve efficiency, many data centers adopt virtualization solutions. The advent of virtualization allows multiple virtual machines hosted on a single physical server. However, this poses new challenges for resource management. Web workloads which are dominant in data centers are known to vary dynamically with time. In order to meet application’s service level agreem...
متن کاملJoint admission control and resource allocation in virtualized servers
In service oriented architectures, Quality of Service (QoS) is a key issue. Service requestors evaluate QoS at run time to address their service invocation to themost suitable provider. Thus, QoS has a direct impact on the providers’ revenues. However, QoS requirements are difficult to satisfy because of the high variability of Internet workloads. This paper presents a self-managing technique t...
متن کاملAdvanced Modelling of Virtualized Servers
In the recent years, server virtualization is one of the most important directions of IT infrastructure development. Simulating virtualized infrastructures are unavoidable for designing cloud systems that are customized perfectly for a company. In this paper, we used Opennebula, Haizea and some other tools under public licenses to experiment with. We executed several experiments to examine meas...
متن کاملCapacity Planning for Virtualized Servers
Today's data centres offer many different IT services mostly hosted on dedicated physical servers. Virtualization provides a technical means for server consolidation leading to increased server utilization. The term refers to the abstraction of computing resources across many aspects of computing and has been used to describe different techniques. Virtualization engines allow hosting multiple v...
متن کاملCharacterizing Workload of Web Applications on Virtualized Servers
With the ever increasing demands of cloud computing services, planning and management of cloud resources has become a more and more important issue which directed affects the resource utilization and SLA and customer satisfaction. But before any management strategy is made, a good understanding of applications' workload in virtualized environment is the basic fact and principle to the resource ...
