• The IT industry loves and lives on buzz words and acronyms– SLAs, ROIs, MTBFs, Mbps, the list goes on and on…– So many, some have to be ‘repurposed’
• Business pressure to contain costs– Equipment costs– Power costs– Cooling costs– Real Estate costs– Personnel costs

What is ‘The Cloud’?

• Ten years ago, ‘The Cloud’ = ‘The Internet’– Now: ‘The delivery of computing as a service, rather than a
product’ (Wikipedia)– Grid Computing = Utility, ‘Always On’
• Depends on who’s defining it– External, Internal– SaaS, PaaS, IaaS
• Amazon EC2• Google Docs, Office 365• DropBox, iCloud• FaceBook, Twitter• NOT ‘The Matrix’…yet…

• Specifically, ‘Hardware Virtualization’• A way to more efficiently use physical compute resources
– Before Virtualization: 10 applications, 10 OS’s, 10 Physical Servers
– After Virtualization: 10 applications, 10 OS’s, 1 Physical Server• Less Power $• Less Cooling $• Less Space $• Less Hardware $
• The Magic is in the ‘Hypervisor’– VMWare ESX– Microsoft HyperV– Citrix XEN
• Originally developed in 1967!
