The objective of this paper is to present a study on Bin packing problem for resource provisioning in cloud. We are going to model it as Class constrained bin packing problem (CCBP) where each server is a bin, items are applications. The class constraint is the limit on the number of applications a server can run simultaneously. | ISSN:2249-5789 Ankita Anoop Rathor et al , International Journal of Computer Science & Communication Networks,Vol 4(6),190-192 Elastic Resource Provisioning for Applications in Cloud Computing Ankita Anoop Rathor Dept.

Of Computer Engineering, PICT, Savitribai Phule Pune University, Pune, India Abstract Cloud computing is an emerging technology that is becoming more and more popular. This is because of its elastic nature . users can acquire or release resources on demand and pay only for the resources they use. Those resources are usually in the form of virtual machines (VM’s). Elastic provisioning of resources means optimum utilization of resources by avoiding over provisioning and under provisioning of resource. The objective of this paper is to present a study on Bin packing problem for resource provisioning in cloud. We are going to model it as Class constrained bin packing problem(CCBP) where each server is a bin, items are applications. The class constraint is the limit on the number of applications a server can run simultaneously. The goal is to pack the applications onto minimum number of servers and hence increasing the demand satisfaction ratio and saving energy by reducing the number of servers used when the load is less. . 1. Introduction Cloud computing is a model for enabling convenient, on-demand network access to a shared pool of configurable computing resources (., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction[8]. The three types of services provided by cloud are IaaS (Infrastructure as a Service),PaaS (Platform as a Service), SaaS (Software as a Service). One of the most important property of cloud computing is elasticity: resources can be scaled up or down as when .
