Sharing-Aware Online Virtual Machine Packing in Heterogeneous Resource Clouds

Towards Virtual Machine Energy-Aware Cost Prediction in Clouds

Pricing mechanisms employed by different service providers significantly influence the role of cloud computing within the IT industry. With the increasing cost of electricity, Cloud providers consider power consumption as one of the major cost factors to be maintained within their infrastructures. Consequently, modelling a new pricing mechanism that allow Cloud providers to determine the potent...

A Privacy-aware Virtual Machine Migration Framework on Hybrid Clouds

With the proliferation of hybrid clouds in both cost-saving and effectiveness, a growing number of users are building their own private cloud. However, private cloud can only provide limited resource, and always resorts to public cloud in order to meet elastic service requirements. Generally, public cloud is operated by commercial service providers (CSPs) who are not completely honest with user...

Risk Aware Resource Allocation for Clouds∗

Cloud computing offers on-demand access to large-scale computing resources in a pay-as-you go manner. Market-based resource allocation mechanisms are gaining popularity among commercial cloud providers to deal with dynamically fluctuating resource demands. For example, the recently introduced Amazon EC2 spot instances allow users to bid for computing resources and thus control the cost vs. reli...

Virtual Machine Placement in Computing Clouds

Communication-Aware Traffic Stream Optimization for Virtual Machine Placement in Cloud Datacenters with VL2 Topology

By pervasiveness of cloud computing, a colossal amount of applications from gigantic organizations increasingly tend to rely on cloud services. These demands caused a great number of applications in form of couple of virtual machines (VMs) requests to be executed on data centers’ servers. Some of applications are as big as not possible to be processed upon a single VM. Also, there exists severa...
