Cloud computing is modus operandi of manipulating server clusters hosted at secluded sites on Internet for storage, processing, and retrieval of data. It tenders suppleness, disaster recovery, competitiveness, and cutback in capital and operational cost for ventures, principally small and medium ones, which hold meager resource base. Virtualization at plinth of cloud computing sanctions utilizing physical hardware stratum to frame and administer virtualized infrastructure, storage areas, and network interfaces. Virtual machines, administered on clouds to seize inherent advantages of virtualization, are fabricated on storage area networks (Armbrust et al., 2009). But whenever user endeavors to access them from remote location it resulted in hundreds of megabytes of data reads and ensuing congestion in network. Question is how to instigate virtual machines and load their applications in minimal time. The ingenious Ceaseless Virtual Appliance Streaming system assures virtual machine's streaming just like video on demand. It trims down burden over existing resources and offers improved network utilization.

Internet came into being with the birth of Arpanet (Advanced Research Project Agency Network) project in 1969, a premium packet switching network relying upon Transmission Control Protocol / Internet Protocol (TCP/IP) protocol suit to transmit data packets between sender and receiver. Funding of Arpanet was supported by Advanced Research Projects Agency (ARPA) of US Department of Defense. Concept and design of packet switching was put forward by US computer scientists Leonaord Kleinrock and Paul Bran in collaboration with their British counterparts Donald Davis and Lawrence Roberts at MIT Lincoln Laboratory, Massachusetts. For Arpanet the genesis of TCP/IP transmission protocol suit was developed by US electrical engineer Robert Kahn in association with his countryman and Internet pioneer Vint Cerf.

Foremost message carried on Arpanet was send from University of California (UC) to Stanford Research Institute (SRI) on October 29, 1969. It was consisted of word “login” but only letters “l” and “o” were carried before the system crashed and communication stalled. Therefore first message ever delivered on Arpanet was “lo”. System recovered about an hour later and full message “login” was finally delivered. The permanent Arpanet connection between UC and SRI was established in November 1969. By March 1970 it stretched out its arms to US eastern coastal regions and by 1973 it broadened its area beyond the Atlantic Ocean through satellite transatlantic communication link with Norwegian Seismic Array (NORSAR) of Norway.

Concurrently London was also connected with the laying of terrestrial circuits. By 1975 Arpanet became thoroughly operational under the control of US Defense Communication Agency presently known as US Defense Information Systems Agency (DISA). In 1983 military and civilian networks were bifurcated, sinking the volume of Arpanet from 113 to 68 nodes. Gateways were constructed to deliver electronic mails (emails) between these isolated entities. In 1991 Arpanet was finally ceased to exist and substitute by Internet.
