Cloud computing system is not a product, not a service and is not a technology. This is an approach that leads to a new strategy that incorporates complete rethinking of the role of information technology (IT) in organizations. Old notions of work IT divisions must give way to a new approach giving priority to the work of IT. Design and creation of a system for Cloud computing is necessary modernization of IT. In the area of information and communication technologies a virtualization is a term in common use, which generally refers to the use of computing resources to simulate the real hardware, operating systems, platforms, etc. Virtualization makes it possible to start multiple operating systems and application software on a hardware machine that simultaneously allows for efficient use of available resources

A report on IPv6 deployment activities and issues at Sandia National Laboratories:FY2007.

Internet Protocol version 4 (IPv4) has been a mainstay of the both the Internet and corporate networks for delivering network packets to the desired destination. However, rapid proliferation of network appliances, evolution of corporate networks, and the expanding Internet has begun to stress the limitations of the protocol. Internet Protocol version 6 (IPv6) is the replacement protocol that overcomes the constraints of IPv4. As the emerging Internet network protocol, SNL needs to prepare for its eventual deployment in international, national, customer, and local networks. Additionally, the United States Office of Management and Budget has mandated that IPv6 deployment in government network backbones occurs by 2008. This paper explores the readiness of the Sandia National Laboratories network backbone to support IPv6, the issues that must be addressed before a deployment begins, and recommends the next steps to take to comply with government mandates. The paper describes a joint work effort of the Sandia National Laboratories ASC WAN project team and members of the System Analysis & Trouble Resolution, the Communication & Network Systems, and Network System Design & Implementation Departments
