“Computer Utilities” Vision: Implications of the Internet n 1969 – Leonard Kleinrock, ARPANET project “Computer Utilities” Vision: Implications of the Internet n 1969 – Leonard Kleinrock, ARPANET project n n “As of now, computer networks are still in their infancy, but as they grow up and become sophisticated, we will probably see the spread of ‘computer utilities’, which, like present electric and telephone utilities, will service individual homes and offices across the country” Computers Redefined n 1984 – John Gage, Sun Microsystems n n 2008 – David Patterson, U. C. Berkeley n n 4 “The network is the computer” “The data center is the computer. There are dramatic differences between of developing software for millions to use as a service versus distributing software for millions to run their PCs” 2008 – “The Cloud is the computer” – Buyya!

However, their services are priced out of reach for all but the largest enterprise customers. Hence, we have developed an alternative approach to content delivery by leveraging infrastructure ‘Storage Cloud’ providers at a fraction of the cost of traditional CDN providers – “pay as you go”
