  1. GREEN CLOUD By Sphoorthy

  2. WHAT IS CLOUD COMPUTING? • Cloud computing is a model for enabling convenient, on-demand network access to a shared pool of configurable computing resources like networks, servers, storage, applications, and services.

  3. WHAT IS GREEN COMPUTING? • Green computing is the environmentally responsible and eco-friendly use of computers and their resources. In broader terms, it is also defined as the study of designing, manufacturing or engineering, using and disposing of computing devices in a way that reduces their environmental impact. • Green Cloud computing is envisioned to achieve not only efficient processing and utilization of computing infrastructure, but also minimize energy consumption.

  4. Cloud Advantages • Reduce spending on technology infrastructure. Maintain easy access to information with minimal upfront spending. Pay as you go based on demand. • Globalize your workforce on the cheap. People worldwide can access the cloud, provided they have an Internet connection. • Streamline processes. Get more work done in less time with less people. • Reduce capital costs. There’s no need to spend big money on hardware, software or licensing fees. • Improve accessibility. You have access anytime, anywhere, making your life so much easier! • Minimize licensing new software. Stretch and grow without the need to buy expensive software licenses or programs. • Improve flexibility. You can change direction without serious financial issues at stake.

  5. Dark side of Cloud • Gartner Report 2007: IT industry contributes 2% of world's total CO2 emissions • U.S. EPA Report 2007: 1.5% of total U.S. power consumption used by data centers which has more than doubled since 2000 and costs $4.5 billion

  6. Why is green computing needed in cloud? • Cloud Data Centers consume excessive amount of energy: • According toareport on “Revolutionizing Data Center Energy Efficiency” : A typical data center consumes as much energy as 25,000 households. • The total energy bill for data centers in 2010 was over $11 billion and energy costs in a typical data center doubles every five years.

  7. Clouds Impact on the Environment • Data centers are not only expensive to maintain, but also unfriendly to the environment. • Carbon emission due to Data Centers worldwide is now more than both Argentina and the Netherlands emission. • High energy costs and huge carbon footprints are incurred due to the massive amount of electricity needed to power and cool the numerous servers hosted in these data centers.

  8. Performance  Energy Efficiency • As energy costs are increasing while availability decreases, there is a need to shift focus from optimising data center resource management for pure performance alone to optimising for energy efficiency while maintaining high service level performance.

  9. Cloud Providers Measures Cloud service providers need to adopt measures to ensure that their profit margin is not dramatically reduced due to high energy costs. • Amazon.com’s estimate the energy-related costs of its data centers amount to 42% of the total budget that include both direct power consumption and the cooling infrastructure amortized over a 15-year period. • Google, Microsoft, and Yahoo are building large data centers in barren desert land surrounding the Columbia River, USA to exploit cheap hydroelectric power.

  10. Green Cloud Computing Architecture

  11. User: Green Broker • A typical Cloud broker • Lease Cloud services • Schedule applications • Green Broker • 1st layer: Analyze user requirements • 2nd layer: Calculates cost and carbon footprint • of services • 3rd layer: Carbon aware scheduling

  12. Provider: Green Middleware

  13. Case Study: IaaS Cloud • Carbon Emission Directory: Stores all carbon emission rates for each IaaS provider • Green Offer Directory: Receives number of VMs that can be initiated at a particular time for maximum energy efficiency • Green Broker: Computes schedule with the lowest carbon emission based on application requirements

  14. Green Offer & Carbon Emission Directory • Carbon Emission Directory • Contains data on Power Usage Effectiveness (PUE), cooling efficiency, carbon footprint, network cost • Helps user to select cloud services with minimum carbon footprint • Incentive for providers Advertising tool to increase the market share, e.g. Google • Require more carbon transparency from providers Government role by enforcing policies such as Carbon Tax • Green Offer Directory • Incentive for users • Choosing more carbon efficient hours • Lists services with their discounted prices and green hours

  15. Conclusion • Clouds are essentially Data Centers hosting application services offered on a subscription basis. However, they consume high energy to maintain their operations.  high operational cost + environmental impact • Presented a Carbon Aware Green Cloud Framework to improve the carbon footprint of Cloud computing. • Open Issues: Lots of research to be carried out for Maximizing Efficiency of Green Data Centers and Developing Regions to benefit the most.
