  1. An Introduction to Clouds Presented by: Prof Mark Baker ACET, University of Reading Tel: +44 118 378 8615 E-mail: Mark.Baker@computer.org Web: http://acet.rdg.ac.uk/~mab mark.baker@computer.org

  2. What is Cloud Computing? • Providing Software as a Service (SaaS) - delivering applications over the Internet. • More recently also Hardware infrastructure, platform as a service. • Based on Utility Computing - pay-as-you-go: • The under lying idea of infinite resources, • No up-front costs, • Billing (e.g. hourly). mark.baker@computer.org

  3. Different Cloud Computing Layers‏ MS Live/ExchangeLabs, IBM, Google Apps; Salesforce.com Quicken Online, Zoho, Cisco Application Service (SaaS)‏ Google App Engine, Mosso, Force.com, Engine Yard, Facebook, Heroku, AWS Application Platform 3Tera, EC2, SliceHost, GoGrid, RightScale, Linode Server Platform Storage Platform Amazon S3, Dell, Apple, ... mark.baker@computer.org

  4. Virtualization • Virtual workspaces: • An abstraction of an execution environment that can be made dynamically available to authorised clients by using well-defined protocols, • Resource quota (e.g. CPU, memory share) • Software configuration (e.g. O/S, provided services) • Implement on Virtual Machines (VMs): • Abstraction of a physical host machine • Hypervisor intercepts and emulates instructions from VMs and allows management of VMs • VMWare, Xen, etc. • Provide infrastructure API: • Plug-ins to hardware/support structures App App App OS OS OS Hypervisor Hardware Virtualized Stack mark.baker@computer.org

  5. Cloud-Sourcing • Why is it becoming a Big Deal: • Using high-scale/low-cost providers, • Any time/place access via web browser, • Rapid scalability; incremental cost and load sharing, • Can forget need to focus on local IT. • Concerns: • Performance, reliability, and SLAs, • Control of data, and service parameters, • Application features and choices, • Interaction between Cloud providers, • No standard API – mix of SOAP and REST! • Privacy, security, compliance, trust… mark.baker@computer.org

  6. Different types of Cloud • Amazon: • Computing in the cloud! • EC2 (with S3, SQS and SimpleDB), • Use Xen VMs, • Workflow and Security. • Google: • Apps: Python module/API, • Working also with IBM. • Microsoft: • Azure! • Yahoo: • Pipes, Working with Computational Research Laboratories • Sun/IBM/HP and others… mark.baker@computer.org
