Transcript of "Cloud Computing_Web Tools_5-19-10_Nicole Siegel"

  1. 1. CLEARING UP CLOUD COMPUTING<br />By Nicole Siegel<br />May 19, 2010<br />
  2. 2. WHAT IS CLOUD COMPUTING?<br />
  3. 3. WHAT IS A CLOUD<br />The term "cloud" is used as a metaphor for the Internet.<br />The cloud is a batch of computers called data centers or servers that hold your information (files, images, videos, etc.) and can be located anywhere. <br />Some claim that the phrase cloud computing was inspired by the cloud symbol that's often used to represent the Internet in flowcharts and diagrams.<br />
  4. 4. SO WHAT IS CLOUD COMPUTING?<br />
  5. 5. CLOUD COMPUTING….<br />When data or software applications are not stored on a user’s computer, but rather are accessed through the web from any device at any location.<br />The server and computing environment exist in a virtual sense, and aren’t tied to any one particular machine. <br />Files and applications are basically floating around in a “cloud of resources”, making the hardware less important.<br />Cloud computing customers do not own the physical infrastructure but rather rent usage from a third-party provider (there are paid and unpaid models).<br />Also known as grid computing, utility computing, software as a service, Internet-based applications, autonomic computing, peer-to-peer computing and remote processing.<br />
  6. 6. A BRIEF HISTORY<br />Years ago, computing was largely centralized. Users accessed information and programs on mainframe computers (such as Microsoft and Adobe).<br />The underlying concept of cloud computing dates back to 1960, when John McCarthy declared that “computation may someday be organized as a public utility.”<br />Amazon played a key role in the development of cloud computing, providing access to their systems through Amazon Web Services (remote computing services).<br />Recent evolutions in information technology (and the growth in broadband access) have led to a more distributed computing environment.<br />
  7. 7. 3 CATEGORIES<br />Infrastructure-as-a-Service (IaaS)<br />Outsources the equipment used to support operations, including storage, hardware, servers and networking components. The service provider owns the equipment and is responsible for housing, running and maintaining it.<br />Examples: Amazon EC2, Rackspace Cloud<br />Platform-as-a-Service (PaaS)<br />Delivers operating systems and application platforms over the Internet without downloads or installation.<br />Examples: Google App Engine, Force.com<br />Software-as-a-Service (SaaS)<br />Delivers software as a service over the Internet, eliminating the need to install and run on a computer.<br />Examples: Gmail, Wordpress.com<br />
  8. 8. HOW IT WORKS<br />
  9. 9. HOW IT WORKS<br />Imagine that the cloud consists of layers — the back-end layers and the front-end or end-user layers.<br />When email is accessed on Gmail for example, software is running on the front-end of a cloud. The same is true with access to Facebook accounts.<br />The back-end consists of the hardware and the software architecture that fuels the interface you see on the front-end.<br />
  10. 10. HOW IT WORKS<br />Cloud computing works by hosting information on computers out ‘in the cloud’. Work is then done in a cloud since it is not necessary to store software or files on an individual computer. <br />Typical cloud computing providers deliver common business applications online which are accessed from another web service or software like a web browser, while the software and data are stored on servers.<br />Web-based programs, like Hotmail, Gmail, Google Docs and Facebook run in the browser and contain data which exists outside of a computer, or "in the cloud."<br />
  11. 11. EXAMPLES<br />
  12. 12. EXAMPLES<br />Many people have already transitioned to using a cloud environment without even realizing it:<br />Webmail services such as Hotmail, Gmail and Yahoo! <br />Online photo storage/albums such as Snapfish, Picassa and Kodak<br />Google documents<br />Video upload sites such as YouTube, Vimeo<br />Hard drive back-up sites<br />Social bookmarking<br />Presentation storage<br />Social networking sites such as Facebook<br />
  13. 13. WHO IS USING IT<br />
  14. 14. WHO IS USING IT<br />WiFi connectors are enthusiastic and are the most avid adopters.<br />Younger Internet users are more inclined than older ones to use services or applications that require personal data to be stored online.<br />A large company that has employees in numerous locations running specialized software to carry out data-intensive tasks.<br />Business travelers needing access while away from their computer.<br />Students looking to work remotely.<br />
  15. 15. ADVANTAGES<br />
  16. 16. ADVANTAGES<br />Accessibility<br />Agility<br />Cost effective<br />Easy and convenient<br />Environmentally friendly<br />Flexibility<br />Low Maintenance<br />Reliability<br />Shareability<br />
  17. 17. DISADVANTAGES<br />
  18. 18. DISADVANTAGES<br />Inconsistent<br />Lack of privacy<br />Learning curve<br />Less control over personal information<br />Liability<br />New technology<br />Reliant on Internet<br />Security issues<br />
  19. 19. WHAT IT ALL MEANS<br />
  20. 20. FUTURE OF CLOUD COMPUTING<br />Cloud computing is changing the way we use the web and store files.<br />With broadband Internet, the need to have hardware/software run on a computer is becoming less essential.<br />According to Steve Ballmer, "It's the next step, it's the next phase, it's the next transition.”<br />John Herlihy of Google Europe has essentially mirrored those thoughts, calling the desktop an item that will be "irrelevant" in three years. Why? Largely because most everything you'll need a tower for will be available via a mobile or the web.<br />
  21. 21. FUTURE OF CLOUD COMPUTING<br />We are transitioning from being very ‘personal hardware dependent’ to a world where resources are shared among the masses. <br />For businesses, cloud computing translates to greater efficiencies and collaboration (and IT staff and budget reductions). <br />For the average internet user, we'll start seeing a more networked world in which we'll be using our computers and mobile devices to easily access information stored elsewhere.<br />
