Transcript of "Cloud Computing Introduction"

  1. 1. Cloud Computing Eurécom Adomas Svirskas Sophia-Antipolis France The 3rd meeting of the Special Interest Group on eBusiness and eCommerce, Kingston University, 12/05/2009
  2. 2. Today’s Topics • What is Cloud Computing? • Why do we care? • Flavors of the Cloud Computing • What Cloud Computing can do for us? • Important things to keep in mind • It is cool, now what? How to reach the clouds?
  3. 3. What is Cloud Computing • Anyone…? • Ask 10 IT professionals and you will end- up with 10 different answers • Cloud computing (CC) is a way of providing both hardware and software as a service via the Internet, on demand
  4. 4. Cloud Computing Combines • The concept of software-as-a-service (SaaS), where a software application is accessed and used in a hosted environment • Together with the concept of utility computing, where shared, scalable software and hardware is purchased on a usage basis (IaaS, PaaS)
  5. 5. Why do we care? • Because the whole world is nuts about it? • Because it is a new shiny “gadget”? • Well, yes by definition we are geeks  • However, more practically… – Because it can save money (for everyone of us) – Because we need to teach students, CC is already very important in the field – Gives us interesting research opportunities
  6. 6. IaaS, PaaS, SaaS … XaaS… ? • Infrastructure as a Service - computing resources such as servers, storage, and other forms of low level network and hardware resources offered in a virtual, on demand fashion over the Internet • IaaS in a general sense, delivers value similar to what one might find in a traditional datacenter • Examples – GoGrid, Amazon EC2, etc
  7. 7. PaaS • Platform as a Service - a runtime-system and application framework that presents itself as an execution environment and computing platform available over the Internet with the sole purpose of acting as a host to application software
  8. 8. PaaS • It is foundation upon which it is possible to build highly scalable and robust Web- based applications in the same way that the traditional operating systems like Windows and Linux have done in the past for software developers. • Operational capability of the platform hosting is the primary value here
  9. 9. Evolution of Google PaaS
  10. 10. SaaS • Software as a Service - Specialized software functionality delivered over the Internet to users who intend to use the set of delivered functionality to augment or replace their application domain solutions • Examples: Salesforce.com CRM, or SugarCRM
  11. 11. SaaS vs. PaaS vs. IaaS http://www.saasblogs.com/2008/12/01/demystifying-the-cloud-where-do-saas-paas-and-other-acronyms-fit-in/
  12. 12. XaaS Taxonomy
  13. 13. CC Taxonomy
  14. 14. What CC can do for us? • Save money by moving a part of IT expenses from capital investment to operational expenses • Unlock virtually unlimited computational resources • Augment and complement SOA concepts and solutions
  15. 15. Not to forget • It is still Day One of CC • Availability issues, outages, downtimes • Jurisdiction aspects, e.g. WHERE the data is stored • Security and Privacy • Licensing, contractual issues • Standardization (your cloud is not my cloud yet we need to talk…)
  16. 16. Summary • The field is new, huge and promising • CC is a REALITY – Industry support (CC Expo in New York was a good place to experience this) – Open source support – Research community interest • Every IT professional must be knowledgeable in CC area • CC is available to try it out
