  6. DEFINITIONS: "Clouds are a large pool of easily usable and accessible virtualized resources (such as hardware, development platforms and/or services). These resources can be dynamically reconfigured to adjust to a variable load (scale), allowing also for an optimum resource utilization. This pool of resources is typically exploited by a pay-per-use model in which guarantees are offered by the Infrastructure Provider by means of customized SLA“ - Vaquero, L., L. Rodero-Merino, et al. (2008)

  7. Cloud computing is simply a buzzword used to repackage grid computing and utility computing, both of which have existed for decades.”

  8. Evolution from Grid to Cloud Computing

  9. Public Cloud: The services are delivered to the client via the Internet from a third party service provider. • Example: Amazon

  10. Private Cloud: These services are managed and provided within the organization. There are less restriction on network bandwidth, fewer security exposures and other legal requirements compared to the public Cloud. • Example: HP Data Centers

  11. It is a combination of services provided by the Private and public cloud • Example: • ERP in private cloud • Sales & Email in public

  12. MAJOR CLOUD COMPUTING SERVICES

  13. IAAS • IAAS (Infrastructure as a service) • Offers capacity for rent, basically hosted data centers and Servers • An evolution of web site and server hosting services provided by VPS • Examples: • Verizon's CAAS (Computing as a service) • AT&T (Hosting & Storage)

  14. PAAS • PAAS (Platform as a service) • Platforms enable application developers to host their services • Example: • Google’s App Engine • Amazon E2C • Microsoft azure

  15. SAAS • SAAS – Software as a service • The application itself is provided by service provider • Examples: • ENTERPRISE: SalesForce.com, WebEx, Officelive • USER MAIL: gmail, Hotmail, Yahoo • USER PICS: flickr, picasa

  16. Amazon • Microsoft windows Azure • Savvis • Google App Engine • Vmware cloud • Rack space • Go grid

  17. Reduced Hardware equipment for end users • Improved Performance • Lower Hardware and Software Maintenance • Instant Software Updates • Accessibility • Pay for what we use • Security Issues • Internet connection • Features may be limited • Location of Servers • Speed
