2. Agenda
• What is green IT?
• Key reasons to adopt green IT
• Emerging green technologies and benefits
– Cloud computing
– Virtualization
– Green data centers
• Products of top green technology firms
• Success metrics used by senior managers
3. Green IT
Green IT or green computing is the
study and practice of using computing
resources in ways that help reduce
energy and operating costs, enable
sustainable business practices and
reduce the environmental impact of IT
practices in the larger community
4. Reasons to Adopt Green IT
• Broader interest and emphasis on
corporate social responsibility (CSR)
• Rising energy costs
• Attract and retain customers
– Increasing public awareness
– Positive environmental brand image
• Government agencies have implemented
standards and regulations that promote
green computing
5. Cloud Computing
• Cloud computing refers to computing
services provided over the Internet (or
“cloud”), whereby shared resources,
software, and information are provided to
computers and other devices on demand
• Pros: fast start-up & business agility, low
entry cost with on demand pricing
• Cons: highly dependent on provider,
privacy and security risks
7. Green Benefits of the “Cloud”
• Green Benefits
– Increased efficiencies (power efficiency)
– Resource sharing minimizes wasted resource
– Operating servers at higher utilization rates
• Examples:
– Amazon’s Elastic Compute Cloud (EC2):
Rent virtual-machine instances & hardware
– Google’s App Engine: Web development
platform to build and host Web applications
8. Virtualization
• Virtualization means to create a virtual
version of a device or resource, such as a
server, storage device or network where
the framework divides the resource into
one or more execution environments
• Pros: server consolidation, resource
flexibility, portability & disaster recovery
• Cons: unpredictable performance, risky to
put multiple systems on one host
10. Green Benefits of Virtualization
• Green Benefits
– Cut power demand (electricity for powering
and cooling) through consolidation
– Get more out of existing resources and
reduce costs by shrinking number of servers
• Examples:
– VMware Server Virtualization: Partitions a
physical server into multiple virtual machines
– Microsoft Virtual PC: Run multiple operating
systems on a single physical computer
11. Green Servers and Benefits
• Solution to the data center energy crisis
• Higher performance servers that require
less energy consumption
• Some contain internal cooling technology
or smart sensors that monitor heat
created by the server and adjust fans
• Unified server cabinet for clustering apps
• Modular tower can add processing power
and memory capacity as needed
13. 10 Steps to Green Data Center
1. Evaluate energy efficiency (monitor & reduce)
2. Redesign cooling system (concentrate cooling)
3. Reconsider redundancy (operate on current needs)
4. Use adjustable equipment (scalable and modular)
5. Virtualize your storage (remap apps for efficiency)
6. Use ENERY STAR-rated appliances
7. Donate or recycle legacy servers (reuse parts)
8. Look outside the data center (natural lighting)
9. Research alternative power sources (solar, wind)
10. Get your management involved
