Cloud Computing, Virtualization
& Green IT
Cloud computing can change how IT
supports business
Consider the following:
•As much as 85% of computing capacity sits idle in distributed computing environments.
•Seventy percent of IT budgets is typically spent on maintaining current IT infrastructures and only 30%
is typically spent on new capabilities.
•Over 30% of consumers notified of a security breach will terminate their relationship with the company that contributed to the breach.

Defining Cloud Computing
Cloud computing has emerged as a new paradigm for:
•Hosting services
•Delivery services
•Allows enterprises to start from small and increase resources on requirement
Defining Cloud Computing
Cloud computing is a new consumption and delivery model for information technology (IT) and business services and is characterized by:
•On‐demand self‐service
•Reliable network access
•Location‐independent resource pooling
•Rapid elasticity and provisioning
•Pay‐per‐use
Cloud and Environmental Sustainability
Cloud Computing
Customer View & Providers View
Cloud Application
• Application rum on user machines via web browser, hosted desktop or remote client.
• User never purchase expensive software licenses
• Cost is incorporated into subscription fees.
• Removes burden of software maintenance, ongoing operations
Cloud platform
• Middle layer which provides computing platform or framework as a services
• Dynamically provisions, configures,
reconfigures, and de‐provisions servers as needed for demand
• Real distributed computing environment
where many services pull together to deliver an application or infrastructure request
Cloud Infrastructure
• Foundation of cloud pyramid
• Deliver IT infrastructure through virtualization
• Infrastructure includes servers, networks, and other hardware appliances
• Virtualization allows physical piece of
hardware into independent, self governed
environments which can be scaled in terms of CPU, memory, storage capacity & other
elements

Types of Cloud
Benefits with Cloud
• Removal/reduction of capital expenditure
• Reduced administrative cost
• Improved resource utilization
• Economies of scale
• Scalability on demand
• Quick and easy implementation
• Anywhere access
• Helps smaller business
Challenges with Cloud
• Less job opportunities for IT staff
• Security Risk
• Internet outage will be a serious problem
Business Impact of Server Consolidation with Virtualization
18
State of Infrastructure Today
Server Sprawl
36M physical x86 servers by 20111— a ten‐fold increase in 15 years1
$140 bn in excess server capacity ‐ a 3‐year supply2
Power & Cooling
50c for every $1 spent on servers2
$29 bn in power and cooling industry wide2
Operating Cost
$8 in maintenance for every
$1 spent on new infrastructure2
20‐30 : 1 server‐to‐admin ratio3
Space Crunch
$1,000 / sqft2
$2,400 / server2
$40,000 / rack2

Using virtual infrastructure, we can offer the same levels of
service and more flexibility for up to 40 percent lower server and operating costs.

Key Task Traditional Approach Virtual Infrastructure Approach
Moving an
application to a new server
• 4 - 6 hours for migration
• Service interrupted for duration of maintenance window
• Requires days/weeks of change management preparation
• 2 - 5 minutes for live migration
Hardware maintenance
• Requires 1 - 3 hour maintenance window
• Requires days/weeks of change management preparation
• Zero downtime hardware upgrades
