Distributed Computing - What, why, how..

  1. 1. Distributed ComputingWhat, why, and how Prepared by arinto <arinto (at) gmail (dot) com>
  2. 2. Outline● What are DCs?● DC in our daily life ○ Dropbox ○ Google Drive ○ Spotify ○ Parallel Processing● DC in Indonesia ○ Energy ○ e-Government
  3. 3. What are DCs? Store and compute!Normal people usage: few hundreds of GB of data, browsing,email...Web companies and scientific communities : Petabytes ofdata!
  4. 4. Petabytes.. so what??!!a MS Word document : 40 KB = 40 kilobytes1 megabyte = 2^10 kilobytes = 1024 kilobytes1 gigabyte = 2^10 megabytes = 1024*1024 kilobytes > 1000000kilobytes1 terabyte = 2^10 gigabytes = 1024 gigabytes1 petabyte = 2^10 terabytes =1024*1024 gigabytes > 1000000 gigabytes > 1000000000000kilobytesGoogle processed 24 Petabytes of data everyday in 2009!
  5. 5. Many as one
  6. 6. Resource Sharing
  7. 7. Fault Tolerance
  8. 8. Scalability
  9. 9. Scalability
  10. 10. Sum them up!● Many as one a.k.a transparent ○ User view them as a whole rather than a collection of cooperating components● Resource sharing ○ Same set of resource shared by multiple users● Fault tolerance ○ Still working despite failing● Scalability ○ System or user can increase easily
  11. 11. Dropbox Store and retrieve dataHow do we transfer data ? ThumbdriveBackup? External HDDStolen?Crashed?
  12. 12. Dropbox X ● Simple access from anywhere ● Simple sharing ● Back up
  13. 13. Dropbox X ● Simple access from anywhere ● Simple sharing ● Back up
  14. 14. Dropbox X DataCenter
  15. 15. Google Drive Write, store and read documentsCollaboration ? Send back and forth.. MyDocuv223.docShare? Send back and forthFree ? No!!!!!Cant access document from other device easily
  16. 16. Google Drive Access your data from anywhere anytime
  17. 17. Spotify Download, store and listen musicHow do we get the music ? Download!Legal? No!!!Clean? No!!!!!Quality? Baddd :(Cant access playlist from other device easily
  18. 18. Spotify Vision: Music service easier and better than illegal music!
  19. 19. Spotify Vision: Music service easier and better than illegal music!
  20. 20. Spotify Peer-to-peer with master backup! Vision: Music service easier and better than illegal music!
  21. 21. Parallel Processinga MS Word document : 40 KB = 40 kilobytesGoogle processed 24 Petabytes of data everyday in 2009!Estimated total document =24*1000000000000 kilobytes / 40 kilobytes = 600000000000If 1 docu needs 0.001 second, we need= 600000000 seconds= 10000000 hours= 416667 days= 1141.5 years!!!!Solution: parallelize!!
  22. 22. DC in Indonesia1. Smart Grid a. Communication between Power Source b. Monitoring and providing appropriate response2. Smart City and Internet of Things a. Building Management b. Interoperability3. e-Government a. Open Data b. Online government service
  23. 23. Smart GridComputinginfrastructure, whichis distributed! Ref: http://www.smartgrid.epri.com/Demo.aspx
  24. 24. Internet of Things (IoT)Nest Smart-Termostat ● Learn our behavior, adjust temperature accordingly ● Connected termostat to internet ● Web-based management portalPromotional video: http://www.nest.com/saving-energy/#videotour
  25. 25. IoT towards Smart City
  26. 26. IoT towards Smart City
  27. 27. IoT towards Smart City
  28. 28. e-Government - Open Data● Open Data Stockholm (http://open.stockholm.se/oppna-data) - Population - Geodata, i.e: urban area, road network - Environmental Data - Traffic and Parking - School data● Open Data Singapore (http://data.gov.sg) - Traffic and Parking
  29. 29. Conclusion1. We know what Distributed Computing is!2. Distributed Computing is real and used in daily life!3. Some applications of Distributed Computing in our beloved country!
