  1. CLOUD COMPUTING

  2. INTRODUCTION Cloud computing is one of the more recent technologies that many businesses, individuals and other industry organizations believe to by one of the keys to the future of information technology.
  3. CLOUD STATISTICS $150 Billion: The size of the cloud computing market by 2013. $750 Million: The amount that Amazon.com AWS expects to earn in 2011. 7/10: Companies using cloud services that will move new applications to the cloud. 54%: Amount of respondents citing Security as their top concern for transition to the cloud. 60%: Server workloads that will be virtualized by 2014. (Ingthorsson, 2011)
  4. Cloud Interest is Growing Google shows the increase of website searches on the topic of cloud computing.
  5. Definition of Cloud Computing The user is able to access files, data, programs and 3rd party services on the Internet hosted by a 3rd party provider (Hudson 2008) Cloud computing means one can purchase or rent complex corporate software and then access and manipulate this software on a relative simple mobile device. (Armburst, et.al,2012)
  6. Attributes of Cloud Computing Massive resources at its disposal and supports several users simultaneously Supports on-demand scalability of users’ computational needs Offers ubiquitous access; stored data and applications are accessible by authorized users anywhere at anytime
  7. Attributes of Cloud Computing Facilitates data sharing, enterprisewide data analysis, and collaboration Are generally self-healing and can self-reconfigure providing continuous availability in case of failure of its computing resources Offers enhanced user experience via a simplified Web browser user interface
  8. Paradigm Shift Transition from computing-as-a-product toward computing-as-a-service. Transition from buying hardware and software as products that we install, to using applications and computing infrastructure in the cloud as a service paying on the go.
  9. Paradigm Shift You aren't tied to a particular computer or a specific private network to run or access your applications and data. Easier for group members in different locations to collaborate
  10. Service Models Web-based application offered via cloud computing is called a cloud service. Cloud services range from simple applications such as e-mail, calendars, word processing, and photo sharing Complex enterprise applications and computing resources offered as services by major providers
  11. SaaS- Software as a Service End-user applications are hosted by a cloud vendor and delivered as a service. "on-demand" billing system or free eliminates the need to locally install and run the application on the user's computer, The software license is not owned by the user.
  12. Examples of SaaS Google Apps Salesforce.com CRM Quicken Online Accounting NetSuite’s Business Software Suite
  13. (PaaS) Platform as a Service Application development platforms and middleware systems are hosted by a vendor and offered to application developers The platform provides most of the tools and facilities required for building and delivering applications Examples Google App Engine Microsoft Azure Amazon.com’s Web Services
  14. (IaaS) Infrastructure as a Service Servers, CPU, storage, network equipment, and data center facilities, are delivered as a service on demand The service is billed according to the resources consumed. Examples of IasS Amazon Elastic Compute Cloud (EC2), GoGrid FlexiScale
  15. Cloud for Small Business and Individuals Google Gmail- communication service Calendar- time-management system Groups - collaboration/discussion Docs- word processing/spreadsheet application Dropbox-file sharing system Basecamp - web project management system Highrise - shared contact system (CRM) Backpack - personal information manager and intranet Campfire- business online chat service Evernote -web note taking service Xero-online accounting service
  16. Advantages & Disadvantages Advantages Easy to use Low cost or no cost Automatic software updates Improved PC performance Universal document access Unlimited storage capabilities Collaboration abilities Disadvantages Security Slow internet connection Lack of understanding as to what the cloud actually is.
  17. Lack of Understanding the Cloud 51% believe stormy weather would interfere with their cloud computing 54% claim to never use the cloud 17% have pretended to know what the cloud was during a first date 95% of those who think they’re not using the cloud, actually are Survey commissioned on behalf of the Centrix Organization (McKendrick2012)
