Cloud Computing

  1. 1. Presented By: Manjiri Kharat Felsita Mekapogu Monali Ahire Monali Kolapkar
  2. 2. What is Cloud Computing?  “cloud” is methaphor for internet.  The name cloud computing was inspired by the cloud symbol that's used to represent the Internet in flowcharts and diagrams.  Users simply rent or access the software, paying only for what they use .
  3. 3. History of Cloud Computing  Concept dating back to the 1960’s by John McCarthy, a computer scientist, brought up the idea that "computation may someday be organized as a public utility”  Moving from clustering computing to grid computing this idea revolutionized Cloud Computing
  4. 4. Potential Issues • Data residency – time delay between data being requested and delivered • Security and confidentiality of data being stored outside the company • Business buy-in; convincing companies of the infrastructure and reliability
  5. 5. Functionality  Cloud computing is an emerging technology that is revolutionizing IT infrastructures and flexibility, and software as a service (SaaS)  During this economic time of recession, there are huge cost-reduction pressures and cloud computing allows businesses to do just that by tapping into cloud computing platforms on a pay-as-you-go basis  Software and applications are extremely costly. With cloud, you rent so the heavy investment is forgone
  6. 6. Functionality CONTD…..  Cloud computing is a set of technologies and business practices that enable companies of all sizes to build, deploy, monitor and scale applications using resources accessed over the internet  A cloud can be private or public.A public cloud sells services to anyone on the Internet. A private cloud is a proprietary network or a data center that supplies hosted services to a limited number of people  The goal of cloud computing is to provide easy, scalable access to computing resources and IT services.
  7. 7. Some Commercial Cloud Offerings 8
  8. 8. Cloud Computing Usage
  9. 9. Infrastructure as a Service  Defined as delivery of computer infrastructure as a service  Infrastructure providers can dynamically allocate resources for service providers
  10. 10. Platform as a Service  Provides all the facilities necessary to support the complete process of building and delivering web applications and services, all available over the internet  Infrastructure providers can transparently alter the platforms for their customers’ unique needs
  11. 11. Software as a Service  Defined as service-on- demand, where a provider will license software tailored  Customers can utilize greater computing power while saving on the following – – – – Cost Space Power Consumption Facility
  12. 12. • Reduced Hardware equipment for end users • Improved Performance • Lower Hardware and Software Maintenance • Instant Software Updates • Accessibility • Less Expensive (Amazon example) • Better Collaboration • Pay for what you use • Flexible
  13. 13. • Security Issues • Internet connection • Too many platforms • Location of Servers • Time for Transition • Speed
  14. 14. Future Educational Uses  More useful spending of technology budgets  Classroom collaboration  Office Web Applications  Google Docs
  15. 15. Future Personal Uses  No more backing up files to thumb drives or syncing computers together  Services replace devices  A single hard drive for the rest of a person’s life, accessible anywhere with internet
