Defining Cloud
“A standardized IT capabilitydelivered via Internet technologiesin a pay-per-use and self-service
way.”
“How To Message Cloud Offerings And Not Get Lost In The Fog”, Forrester Research, Inc., July 2009
Browser-based with minimal local compute; N-scale service
Highly transactional; dynamic scaling/flexing
Real-time
Granular metering; priced based on delivering ongoing “shared value”
SLA rests with ISV or hoster
Multi-tenant, built for a market, not a customer
For users this means…
IDC on The Cloud: (http://blogs.idc.com/ie/?p=189)
Location and Responsibility: Offsite, provided by third-party provider - “In the cloud” execution, location-agnostic
Access: Via the Internet to standards-based resources, with universal network access
Skills required: Minimal IT skills to “implement” - online, simplified specification of services and no lengthy implementation of on-premise systems
Provisioning: Automated provisioning, self-service requesting, near real-time deploymentPricing: Fine-grained, usage-based pricing capability (though some providers mask this granularity with long-term, fixed price agreements)
Infrastructure: Shared resources, configure vs. customize, with integrations and client-side optimization, often virtualized
What’s Different About Cloud

IT Evolution
“By 2012, 80% of Fortune 1000 enterprises will be using some cloud computing services, 20% of businesses will own no IT assets.”
“The bottom line: Early adopters are finding serious benefits, meaning that cloud computing is real and warrants your scrutiny as a new set of platforms for business applications.”
“A new delivery method is shaking the software industry’s foundations.”
“69% of Indian CIOs feel that it will be the most DISRUPTIVE TECHNOLOGY in the coming year”
