Cloud computing1

  1. 1. “CLOUD COMPUTING” presented by anurika arora 2006eec50<br />
  2. 2. Contents<br />Introduction to Cloud Computing<br />How is it any different?<br />Components <br />Cloud Architecture<br />Types of Clouds<br />Virtualization <br />Cloud Characteristics<br />Related works <br />List of References<br />
  3. 3. What are Clouds?<br />Clouds are “Virtual Clusters”<br />Clouds support access of(lease of) computer instances<br />Instances accept data and job descriptions (code) and return results that are data and status flags<br />The datacenter with hardware and software is what we will call a Cloud.<br />
  4. 4.
  5. 5. What is Cloud Computing<br /> “A computing cloud is a set of network enable services providing scalable, QoS guaranteed, normally personalized, inexpensive computing infrastructures on demand, which could be accessed in a simple and pervasive way.”<br />
  6. 6.
  7. 7. Components<br />Client<br /> Mobile (Android, iPhone, Windows Mobile)<br />Thin client (Cherry Pal, Zonbu, gOS-based systems)<br />Thick client / Web browser (Apple Safari, Mozilla Firefox, Google Chrome, Opera, Microsoft Internet Explorer) <br />Service<br />Integration (Amazon Simple Queue Service) <br />Payments (Amazon Flexible Payments Service, Google Checkout, PayPal) <br />Mapping (Google Maps, Yahoo! Maps, MapQuest) <br />

  17. 17. Virtualization technology<br />Virtual machine is a software implementation of a real machine<br />Full virtualization<br /> Instead of 100 physical servers ,we can now have 100 virtual server images running on 1 physical server, this reduces the used infrastructure<br />Platform virtualization<br />Application virtualization<br /> Virtual appliances<br />Significance :<br />Server consolidation<br />Virtual memory<br />
  18. 18. Parallelization and virtualization <br />
  19. 19. Data-intensive processing<br />
  20. 20. <ul><li>Virtual machine images can be easily updated and redeployed
  21. 21. If any physical server fails then the virtual machines that it was hosting are simply restarted on different physical server</li></li></ul><li>
  22. 22. Related works and results<br />Microsoft: Software plus Services<br />IBM: Transformation through Customer Implementations<br />Cisco: Evolving Interoperability<br />
  23. 23. MICROSOFT: SOFTWARE PLUS SERVICES<br />Windows Azure Services Platform.<br /> The Azure platform is hosted in Microsoft data centers.<br />It facilitates:<br />Development of applications<br />Improved Service management<br />Improved Service-hosting<br />Several Microsoft SaaS applications already run on the Azure platform<br />
  24. 24. IBM: Transformation through CustomerImplementations<br />
  25. 25. CISCO: EVOLVING INTEROPERABILITY<br />Cisco adopted Web 2.0-based collaboration products. <br />Interoperability across cloud infrastructures—that is, the intercloud<br />In place of stand alone clouds , enterprise clouds with enhanced security and full interoperability needs to be developed which remains a challenge<br />
