  1. 1. What is Green Computing ?  Green Computing is the term used to donate efficient use of resources in computing.  It is also Known as Green IT.  Green Computing is “ Where organizations adopt a policy of ensuring that the setup and operations of Information Technology produces the minimal carbon footprint” .
  2. 2. What is Green Computing ? (cntd.)  Green Cloud is “ the study and practice of designing, manufacturing , using and disposing of computers , servers and associated subsystems .  Key issues are energy efficiency in computing and promoting environmentally friendly computer technologies .
  3. 3. Goal of Green Computing – • The goals of green computing are similar to green chemistry. • Minimize energy consumption. • Purchasing green energy. • Reducing travel requirements for employees/costumers .
  4. 4. What is Cloud Computing ? • Cloud computing is a metaphor used by Technology or IT Services companies for the delivery of computing requirements as a service to a heterogeneous community of end-recipients. • It is a Virtualized Computing Platform . • Scalable use of computing resources .
  5. 5. CLOUD SERVICE MODELS
  6. 6. 1.Software as a Service: The software is present on clouds and all type processing is done on cloud only. This feature allows users to access the software from any computer which is connected to the internet.
  7. 7. 2.Storage as a Service: This service allow user to outsource their data storage needs to the cloud. The user store all his/her files on cloud but the all kind of processing is done on user’s PC
  8. 8. 3.Processing as a Service: This model provides user the functionality to process complex computation on cloud which consists of powerful servers. Tasks which demand less processing power are carried on user’s PC only.
  9. 9. SUMMARYOF MODELS Software as a Service Storage as a Service Processing as a Service Location of Processing Cloud Client Short task at client, Large tasks in cloud Location of Storage Cloud Cloud Client Function of Transport Transmit commands and receive results All files/documents Files for large tasks
  10. 10. Green Cloud Computing • Green Cloud computing is used to achieve not only efficient processing and utilization of computing infrastructure, but also minimize energy consumption . • It is also called as GREEN IT. • Practice of using computer products efficiently.
  11. 11. Goals Of Green Cloud Computing: • Reduce the use of hazardous material , it causes harm to environment . • “Green” Data Centers. • Using recycle materials. • Supply Chain Energy Usage.
  12. 12. ADVANTAGESOF GREEN CLOUD COMPUTING
  13. 13. Working of Green Cloud Public Cloud B Private Cloud End User Carbon Emission Directory Public Cloud A a) Request a cloud service d) Allocate service e) Request service allocation c) Request energy efficiency information Green Offer Directory b) Request any green offer Routers Internet Green Broker
  14. 14. Green IT in developing regions • Development of ICT • Moving Processor and Data closer to the User • Public Policy measures-Germany example, PPP • Locating Data Centers in the developing world • Economic Growth
  15. 15. Benefits Elastic Market Oriented (Pay As You Go) Virtualized Service Oriented Dynamic & Distributed Shared (Economy of Scale) Cloud Computing
  16. 16. Dark side • 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
  17. 17. Computer Rm. AC 34% Server/Storage 50% Conversion 7% Network 7% Lighting 2% Compute resources and particularly servers are at the heart of a complex, evolving system! Where Does the Power Go? Power Consumption in the Datacenter 3/26/2015 23
  18. 18. Green Cloud Computing Architecture
  19. 19. 1. Consumers/Brokers: • Cloud consumers or their brokers submit service requests from anywhere in the world to the Cloud. It is important to notice that there can be a difference between Cloud consumers and users of deployed services. For instance, a consumer can be a company deploying a Web application, which presents varying workload according to the number of users accessing it.
  20. 20. 2. Green Resource Allocator: • Acts as the interface between the Cloud infrastructure and consumers. It requires the interaction to support energy-efficient resource management.
  21. 21. 3.Virtual Machines (VMs) • Multiple VMs can be dynamically started and stopped on a single physical machine to meet accepted requests, hence providing maximum flexibility to configure various partitions of resources on the same physical machine to different specific requirements of service requests.
  22. 22. 4. Physical Machines: • The underlying physical computing servers provide hardware infrastructure for creating virtualized resources to meet service demands.
  23. 23. Go Green!!! • Presented a Carbon Aware Green Cloud Framework to improve the carbon footprint of Cloud computing • Lots of research to be carried out • Maximizing Efficiency of Green Data Centers • Developing Regions to benefit the most
