Big steps have already been made towards this endeavor by some companies embarking on open source cloud projects. Number one ought to be Amazons’ Eucalyptus project that utilizes Amazon Web Service API which allows cloud service functions. They also support services from open source distributors such as Linux. Another notable example is OpenStack, which is a new but formidable player into open source cloud computing service provision. Their services constitute managing computing and storage through two projects, namely OpenStack Compute and OpenStack Object Storage. Others include the famous OpenNebula, Sheepdog, and Ganeti (all utilize open source tools, Kernel-based Virtual Machine-KVM and Xen).
