Outline● What are DCs?
● DC in our daily life○ Dropbox○ Google Drive○ Spotify○ Parallel Processing
● DC in Indonesia○ Energy○ e-Government
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!
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!
Many as one
Resource Sharing
Fault Tolerance
Scalability
Scalability
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
DropboxStore and retrieve data
How do we transfer data ? Thumbdrive
Backup? External HDD
Stolen?
Crashed?
X
● Simple access from anywhere● Simple sharing● Back up
Dropbox

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
Google Drive
Access your data from anywhere anytime
SpotifyDownload, 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
Spotify
Vision: Music service easier and better than illegal music!

Peer-to-peer with master backup!
Parallel Processinga 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!!
DC in Indonesia1. Smart Grid
a. Communication between Power Sourceb. Monitoring and providing appropriate response
2. Smart City and Internet of Thingsa. Building Managementb. Interoperability
3. e-Governmenta. Open Datab. Online government service
Smart Grid

Computing infrastructure, which is distributed!
Internet of Things (IoT)Nest Smart-Termostat● Learn our behavior, adjust temperature accordingly● Connected termostat to internet● Web-based management portal

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
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!
