Slides for sharing session with PPI Stockholm. The topic is about Distributed Computing, covering what it is, why it is important in our daily life and how we can utilize it in Indonesia.

1. Distributed Computing
What, why, and how
Prepared by arinto <arinto (at) gmail (dot) com>

2. Outline
● What are DCs?
● DC in our daily life
○ Dropbox
○ Google Drive
○ Spotify
○ Parallel Processing
● DC in Indonesia
○ Energy
○ e-Government

3. What are DCs?
Store and compute!
Normal people usage: few hundreds of GB of data, browsing,
email...
Web companies and scientific communities : Petabytes of
data!

4. Petabytes.. so what??!!
a MS Word document : 40 KB = 40 kilobytes
1 megabyte = 2^10 kilobytes = 1024 kilobytes
1 gigabyte = 2^10 megabytes = 1024*1024 kilobytes > 1000000
kilobytes
1 terabyte = 2^10 gigabytes = 1024 gigabytes
1 petabyte = 2^10 terabytes =
1024*1024 gigabytes > 1000000 gigabytes > 1000000000000
kilobytes
Google processed 24 Petabytes of data everyday in 2009!

5. Many as one

6. Resource Sharing

7. Fault Tolerance

8. Scalability

9. Scalability

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. Dropbox
Store and retrieve data
How do we transfer data ? Thumbdrive
Backup? External HDD
Stolen?
Crashed?

12. Dropbox
X
● Simple access from anywhere
● Simple sharing
● Back up

13. Dropbox
X
● Simple access from anywhere
● Simple sharing
● Back up

14. Dropbox
X DataCenter

15. Google Drive
Write, store and read documents
Collaboration ? Send back and forth.. MyDocuv223.doc
Share? Send back and forth
Free ? No!!!!!
Can't access document from other device easily

16. Google Drive
Access your data from
anywhere anytime

17. Spotify
Download, store and
listen music
How do we get the music ? Download!
Legal? No!!!
Clean? No!!!!!
Quality? Baddd :(
Can't access playlist from other device easily

18. Spotify
Vision: Music service
easier and better than
illegal music!

19. Spotify
Vision: Music service
easier and better than
illegal music!

20. Spotify
Peer-to-peer with master backup!
Vision: Music service
easier and better than
illegal music!

21. Parallel Processing
a MS Word document : 40 KB = 40 kilobytes
Google processed 24 Petabytes of data everyday in 2009!
Estimated total document =
24*1000000000000 kilobytes / 40 kilobytes = 600000000000
If 1 docu needs 0.001 second, we need
= 600000000 seconds
= 10000000 hours
= 416667 days
= 1141.5 years!!!!
Solution: parallelize!!

22. DC in Indonesia
1. Smart Grid
a. Communication between Power Source
b. Monitoring and providing appropriate response
2. Smart City and Internet of Things
a. Building Management
b. Interoperability
3. e-Government
a. Open Data
b. Online government service

23. Smart Grid
Computing
infrastructure, which
is distributed!

24. Internet of Things (IoT)
Nest Smart-Termostat
● Learn our behavior, adjust temperature accordingly
● Connected termostat to internet
● Web-based management portal

25. IoT towards Smart City

26. IoT towards Smart City

27. IoT towards Smart City

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. Conclusion
1. 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!
