Nilesh Patkar - Cloud Computing Myths & Realities - Interop Mumbai 2009

  1. 1. Cloud Computing Myths & Realities
  2. 2. What People Says • It’s Application service provider • Network of networks.. Platform of computing • It’s Grid computing • It’s Software as a service • It’s Utility computing • It's just another media excuse to sell magazines. • It’s Component / Web services.. Relabelling what's already there? • It’s a gimmick
  3. 3. What Specialist Says • Gartner defines cloud computing as a style of computing in which massively scalable IT related capabilities are provided “as a service” using Internet technologies to multiple external customers. • Forrester defines cloud computing as a pool of abstracted, highly scalable, and managed compute infrastructure capable of hosting end- customer applications and billed by consumption. • Tim orielly( CEO Orielly) defines cloud as Great way of thinking about how you are going to delivering computer services in future
  4. 4. What the hell is cloud computing?
  5. 5. 3 Layers of Cloud Computing Infrastructure asSoftware as a Platform asService a a Service IaaS PaaS Service SaaS
  6. 6. 3 principles of cloud computing • Elastic unlimited capacity – Get Big Fast • Pay as You Go – Spend cash wisely • Simple, Reliable, Fast – Focus on your idea
  7. 7. Infrastructure itself is programmable
  8. 8. Myth Cloud is new and complicated
  9. 9. Myth Cloud is Grid computing Cloud is Utility computing
  10. 10. Myth Cloud is Component / Web Service
  11. 11. Myth Cloud is Software as a service Cloud is Platform as a service
  12. 12. Myth Cloud is replacing traditional hosting Everything is moving into the cloud
  13. 13. Myth Cloud is Private
  14. 14. Reality is Cloud is not revolutionary – It’s simply a natural evolution
  15. 15. Reality is It’s a blessing for new startup
  16. 16. Reality is Cloud is Green
  17. 17. Reality is Cloud is Open
  18. 18. Reality is Startups and individual developers Enterprise users and developers There are different Perspectives
  19. 19. Reality is Security is concern – Storage & Compute
  20. 20. Reality is Manage Risk Business Efficiency & Agility Equilibrium must be achieved
  21. 21. Reality is The No. 1 barrier to the use of the cloud is IT culture
  22. 22. Case Study – Viacom International In early 2006 Viacom International Japan launched [the] FLUX [platform] with video downloads and a streaming entertainment site, combined with social networking.
  23. 23. Case Study – Viacom International • Problem Statement – Very high user interactions/transactions – Success is to keep users engaged – All user interactions are costly from bandwidth and resource point of view – Video streaming/uploading/downloading/processing – High quality Images uploading/downloading/processing
  24. 24. Case Study – Viacom International • Solution – Used Cloud IaaS to store bandwidth consuming media resources like videos, streams & images – Leveraged Web service interface (Programmable infrastructure) to access resources – Images and videos are processed using Map Reduce distributed processing
  25. 25. Case Study A new startup US Job Portal • Problem Statement – Strong Search engine which can index structured (database) as well as unstructured data such as resumes (word/pdf) – Very high user interactions/transactions – Very short turnaround time – Limited budget
  26. 26. Case Study A new startup US Job Portal • Solution – Rails for fast development – Attivio to index structured & unstructured data – Used Heroku platform as a Service which provides Rails app , HTTP cache, WebServer , database as one packaged platform – Used Amazon S3 to store documents/resumes/images
  27. 27. Case Study – Cloud Cache • A US startup company offerring intra cloud computing Services • CloudCache provides a simple and cost effective on demand caching solution. It enables developers to store data in an in- memory cache for super fast access while decreasing database hits and increasing performance. • Since CloudCache runs in the cloud as a service, developers do not need to run their own servers just for caching. It is just like memcached, but without the maintenance.
  28. 28. Case Study – Cloud Cache • Problem statement – Cloud should have programmable interface – Engage opensource enthusiast to spread this service
  29. 29. Case Study – Cloud Cache • Solution – Developed PHP API ( ) • As a PEAR package • As a PECL library – Developed Rails API – Developed Java API – Developed a working example for the users with phpgeotiles
