  1. 1. Cloud Computing<br />
  2. 2. Agenda<br />1<br />
  3. 3. Our Definition<br />Cloud Computing -<br />The natural evolution of grid computing infrastructure and virtualization techniques that allow a network to logically distribute computing power to its users<br />2<br />
  4. 4. Traditional PC Setup<br />Client PC performs <br /> majority of processes <br />Cloud Computing<br />Dynamically allocates the processing power of several connected servers <br />Software as a Service (SaaS)<br />Platform as a Service (PaaS)<br />3<br />Economies of Scale<br />
  5. 5. Past<br />Mainframes<br />Present<br />Citrix<br />Google Apps<br />Future<br />Thin clients will replace a multitude of PC configurations from home use to video editing<br />4<br />Cloud Evolution<br />

  10. 10. Reduces difficulty of maintaining <br /> several computer configurations<br />Solutions such as Citrix centralize applications<br />Increases mobility <br />Allows IT to focus on efficiency and innovation<br />Utilizing 3rd party computing power or software is a viable alternative<br />Scale up and down on-demand<br />Pay for what you use incrementally<br />Amazon article conversion<br />9<br />Reducing Cost<br />
  11. 11. Cost ofInfrastructure <br />Infrastructure is difficult to develop and maintain<br />Vernon Turner, SVP IDC Enterprise Infrastructure<br />“IT executives are feeling the pinch of their budgets being squeezed…infrastructure remains underutilized“<br />Largest investment is datacenters<br />Cloud computing increases <br /> utilization from ~2% to ~30%<br />10<br />http://www.reuters.com/article/pressRelease/idUS103185+24-Sep-2009+BW20090924<br />http://datacenterjournal.com/content/view/1709/44/<br />
