2 Outline 2 Overview Cloud Approaches Real-World Case Study Large Scale Computing Systems

3 3 Overview Large Scale Computing Systems

4 What is Cloud Computing? 4 Various definitions Wikipedia Web-based processing, whereby shared resources, software, and information are provided to computers and other devices (such as smartphones) on demand over the Internet Gartner a style of computing in which massively scalable IT-related capabilities are provided 'as a service' using Internet technologies to multiple external customers Large Scale Computing Systems

5 Common Understanding about 5 Cloud Computing Web-enabled services (software/platform/infrastructure) Remote datacenter Shared resources via virtualization Outsource maintenance tasks to the hosting organizations Large Scale Computing Systems

6 (Good Luck) Defining Cloud Computing Software-as-a-Service My customer resource management (CRM) system is out on the Internet! Grids vs. Clouds Shared Virtual Resources Batch Jobs vs. Online Applications Different Approaches to State Management Network Diagrams A service is on a cloud somewhere Virtualization Platforms & APIs Hardware can be manipulated with software Source: F. Javadi, Clearing the Air - Cloud Computing : Adobe Air, Google Gears and Microsoft Mesh

7 Grid vs. Cloud Grid Cloud Underlying concept Utility Computing Utility Computing Main benefit Resource distribution / allocation Solve computationally complex problems Negotiate and manage resource sharing; schedulers Provide a scalable standard environment for network-centric application development, testing and deployment Simple user <-> provider model; pay-per-use Domains Multiple domains Single domain Character / history Non-commercial, publicly funded Commercial 7 Source: F.
