Cloud Computing with Open Source Tool :OpenStack

摘要

OpenStack is a especially scalable open source cloud operating system that is a global alliance of developers and cloud computing technologists producing the ubiquitous open source cloud computing platform for public and private clouds. OpenStack provides series of interrelated projects delivering various components for a cloud infrastructure solution as well as controls large pools of storage, compute and networking resources throughout a datacenter that all managed through a Dashboard(Horizon) that gives administrators control while empowering their users to provision resources through a web interface.In this paper, we present a overview of Cloud Computing Platform such as, Openstack, Eucalyptus ,CloudStack and Opennebula which is open source software, cloud computing layered model, components of OpenStack, architecture of OpenStack. The aim of this paper is to show mainly importance of OpenStack as a Cloud provider and its installation.
