Green Computing

• Green computing is the study and practice of environmentally sustainable computing or Information Technology.

• Achieved by reducing the overall power consumption

Cloud Computing

A cloud is a distributed computing system consisting of a collection of interconnected and virtualized computers .

Types of cloud• Saas• Paas • Iaas

Deployment model•Public•Private•Hybrid

Green Cloud Computing

• It is the combination of green computing and cloud computing.

• The green cloud presents a simulation environment for energy aware cloud computing data centers.

Need Of Green Cloud Computing

• In the last compel of years, more data centers are came into existence the energy consumption of these data centers are also increased to a great extent.¹

• In 2007, Gartner estimated that ICT industry generates about 2% of the total global CO2¹

Benefits

1. Reduce energy consumption of computing resources during peak operation.2. Save energy during idle operation.3. Use eco-friendly sources of energy.4. Reduce harmful effects of computing resources.5. Reduce computing wastes

Cloud Enabling Green ComputingAccording to Accenture Report² , there are

following key factors that have enabled the cloud computing to lower energy usage and carbon emission.

• Dynamic Provisioning• Multi-tenancy• Server Utilization• Datacenter Efficiency

Cloud Computing And Energy Usage Model

Cont.• User/Cloud Software Application energy consumption is directly proportional to the

application’s profile.• Cloud software stack for SaaS, PaaS IaaS

Cloud software stack leads to an extra overhead in execution of end user applications.(accounting, monitoring,recoveryetc).

• Network DevicesEnergy consumption is same duringboth peak time and idle time.

Green Cloud Architecture

Cont.• SaaS Level Use datacenters which are energy efficient and

near to user.• PaaS Level Use various energy profiling tools such as

JouleSort.• IaaS Level Use latest technologies for IT and cooling

system to have most energy efficient infrastructure

Case Study: IaaS ProviderFive policies employed for scheduling by

Green Broker• Greedy Minimum Carbon Emission(GMCE)• Minimum Carbon Emission-Minimum

Carbon Emission(MCE-MCE)• Greedy Maximum Profit(GMP)• Maximum Profit-Maximum Profit(MP-MP)• Minimizing Carbon Emission and Maximum

Profit(MCE-MP)

ConclusionGreen policies reduces carbon emission by

almost 20%Even though Green cloud framework

embeds various features to make Cloud computing much more green, there are still many technological solutions are required to make it a reality.
