CLOUD BACKGROUND
• Latest buzz term of the IT Industry!
• Cloud computing dates back to 1969 when J.C.R.
Licklider introduced ARPANET which became the
internet
• Is it Virtualization or Grid Computing or MSP or ASP or
SaaS or what?
• Confusion surrounding the definition
• Ask ten professionals and you will get ten different
answers
• Repackaging of existing technologies

WHAT IS CLOUD COMPUTING?
• Cloud computing is:
– Virtualization of the underlying infrastructure (hardware and data layer) up to the operating system. It is unaware of the application layer
– Allows users to obtain computing capabilities (on-demand) through the internet from a remote network of servers on a pay-as-you-go basis
• Don’t confuse it with hosting services at an ISP
