CC08- Dynamic VM Scaling: Provisioning and Pricing through an Online Auction


The present IaaS cloud allows dynamic scaling of VMs allocated to a client, according to real-time demand of the client. There are two kinds of scaling: horizontal scaling (scale-out) by distributing more VM instances to the client, and vertical scaling (scale-up) by boosting assets of VMs claimed by the client. It has been a daunting issue how to efficiently allocate the resources on physical servers to take care of the scaling demand of clients in a hurry, which accomplishes the best server use and client utility. A going with the basic test is the means by which to viably charge the incremental assets, with the end goal that the economic benefits of both the cloud provider and cloud clients are guaranteed.

There has been online auction designing dealing with dynamic VM provisioning, where the asset offers are not identified with each other, neglecting to deal with VM scaling where later offers may depend on prior offers of a similar client. As the first in the writing, this paper outlines a productive, honest online closeout for asset provisioning and estimating in the down to earth instances of dynamic VM scaling, where: (I) clients bid for customized VMs to use in future durations, and can offer again in the accompanying time to increment assets, demonstrating both scale-up and scale-out options; (ii) the cloud supplier packs the requested VMs on heterogeneous servers for energy cost minimization on the go. We carefully design asset costs kept up for each kind of asset on every server to accomplish edge based online allotment and charging, and in addition, a novel competitive technique based in view of submodularity of the disconnected target, to demonstrate a decent aggressive proportion is accomplished. The efficiency of the online auction is approved through theoretical analysis and trace-driven simulations.
