What is Cloud Computing?
“Cloud computing is Internet-based computing, whereby shared resources, software and information are provided to computers and other devices on-demand, like the electricity grid.”
Wikipedia
Key Attributes of Cloud Computing
Uses Shared Resources
On-Demand Computing
Sharing resources saves you money World class Data Centers
World class scalability, security, reliability World class Quality of Service, SLAs
Pay only for what you use No upfront investment Instant access to technology Scale quickly ….and no money wasted if you fail fast
PrivatePublic
Uses own DC
IT Operated
Control over data Less scale Therefore less savings
Provides SLA to Business IT manages upgrades &
patching. IT manages security &
compliance.
