- 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??!! aMS 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!

- 21. Parallel Processing a MSWord 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!!
