Cloud computing dynamically allocates the processing power of several connected servers, allowing software, platforms, and infrastructure to be accessed as services over the internet. It offers economies of scale by reducing the need to manage hardware, and allows resources to be scaled up or down on demand. While cloud computing offers benefits like reduced costs, increased mobility and flexibility, it also faces challenges around standardization, privacy, security, reliability and early adoption risks.

3. Our Definition Cloud Computing - The natural evolution of grid computing infrastructure and virtualization techniques that allow a network to logically distribute computing power to its users 2

4. Traditional PC Setup Client PC performs majority of processes Cloud Computing Dynamically allocates the processing power of several connected servers Software as a Service (SaaS) Platform as a Service (PaaS) 3 Economies of Scale

5. Past Mainframes Present Citrix Google Apps Future Thin clients will replace a multitude of PC configurations from home use to video editing 4 Cloud Evolution

6. Cloud services operating system Allows developers to write code as they normally would Azure is tasked with allocating processing jobs and ensuring redundancy Removes the need to manage hardware Windows Azure 5 Seminar on Cloud Computing and Windows Azure, UMSL IS Club, Krishna Kumar, Microsoft

10. Reduces difficulty of maintaining several computer configurations Solutions such as Citrix centralize applications Increases mobility Allows IT to focus on efficiency and innovation Utilizing 3rd party computing power or software is a viable alternative Scale up and down on-demand Pay for what you use incrementally Amazon article conversion 9 Reducing Cost

11. Cost ofInfrastructure Infrastructure is difficult to develop and maintain Vernon Turner, SVP IDC Enterprise Infrastructure “IT executives are feeling the pinch of their budgets being squeezed…infrastructure remains underutilized“ Largest investment is datacenters Cloud computing increases utilization from ~2% to ~30% 10 http://www.reuters.com/article/pressRelease/idUS103185+24-Sep-2009+BW20090924 http://datacenterjournal.com/content/view/1709/44/
