2. @YourTwitterHandle #DVXFR14{session hashtag} @erichoresnyi #COIP21 Objectives The  Art  of  Coding  is  about  balancing     UX,  performance,  and  resources     This  talk  does  not  cover  the  unlimited   benefits  of  coding  in  resource  management:     smart  grids,  ciDes,  transports…     This  talk  covers  the  impact  of  IT  resource   management  on  the  planet.  
3. @erichoresnyi #COIP21 What  is  the  ICT  carbon  footprint?   Energy:  40  Nuclear  Plants   2x  France     Greenhouse  Gas   1/2  of  France     Water  consumpDon     1.5  France  
4. @erichoresnyi #COIP21 What  makes  the  ICT  footprint   Make  =  2/3   Making  a  device  emits  100x  GHG  than  its  use   More  energy  used  than  during  lifeDme   Run  =  negligible     Dispose  ≈  1/3  
5. @erichoresnyi #COIP21 Logical  soluDon   Less Make è Less Impact ! BUT Actually, desktop lifespan divided by 3 over the last 30 years ! Where is the catch ?
6. @erichoresnyi #COIP21 The  role  of  Bloatware   Electronic  lifespan  extends  BUT  latest  versions  cannot  run     Windows98-­‐Office97  è  Windows  8-­‐Office   114  more  RAM  needed  in  20  years     Web  pages  get  25%  fader  every  year  
7. @erichoresnyi #COIP21 What  can  we  do  about  it  ?   So#ware  Eco  Design     =   Efficiency:   Same  Performance,   Less  resources  in  RAM,  CPU,  Bandwidth   ê   Less  Make  
8. @erichoresnyi #COIP21 Microso#  Bing     80%  energy  efficiency     by  removing     20%  of  search  results  
9. @erichoresnyi #COIP21 Linkedin     MigraDon  to  node.js     =     Server  infrastructure  /  10   Efficiency  x112  
10. @erichoresnyi #COIP21 Yahoo  vs  Google     ExhausDve  Vs    To-­‐the-­‐point  design   ê   /2  data  sent   +   /5  HTTP  requests   +     /3    CompleDon  Delay  (PLT)  
11. @erichoresnyi #COIP21 SNCF  vs  Capitaine  Train       ExhausDve  vs  To-­‐the-­‐point  design   ê   /5  data   +   /20  HTTP  requests  
12. @erichoresnyi #COIP21 PMU  vs  Betclic     TradiDonal  vs  PerDnent  design   ê   /5  Data   +   /2  TransacDon  Time   +   Challenger=Mobile  Leader  
13. @erichoresnyi #COIP21 Waste  in  code       70%  features     are   never     or  rarely  used   ê   α-­‐  UX  -­‐  ω  
14. @erichoresnyi #COIP21 Network-­‐Based  So#ware:  a  threat?     Data  per  device  grows  51%  per  year   X   Number  of  devices  increases  40%  a  year   X   Bandwidth  increases  19%  a  year   =   Network  impact  doubling  every  year  
15. @erichoresnyi #COIP21 RESTful  API  =  sustainable  code   Network  Based  So#ware   =   SeparaDon  of  concern  client/server   Stateless   Cacheable   Layered  systems,  eg  proxies   Uniform  interface    
16. @erichoresnyi #COIP21 Microservices  =  Be  Responsible   ComponenDzaDon  via  Services   Organized  around  Business  CapabiliDes   Products  not  Projects   Smart  endpoints  and  dumb  pipes   Decentralized  Governance   Decentralized  Data  Management   Infrastructure  AutomaDon   Design  for  failure   EvoluDonary  Design  
17. @erichoresnyi #COIP21 Streaming  APIs       With  cache,  server  load  divided  by  x10  to  100  (facebook,  twider)     If  differenDal,  data  reduced  by  x10  to  100  on  top     Device  badery  consumpDon  divided  by  4  
18. @erichoresnyi #COIP21 Key  Takeaways     ICT  impact  on  earth=40  nuclear  plants,   growing  x2  than  other  sector     Key  ICT  impact:  make  &  dispose   ê   Eco-­‐efficient  design  =  to-­‐the-­‐point  
19. @erichoresnyi #COIP21 Credits   Research  by  F.Bordage  @greenit   Cisco  VNI:  y-­‐o-­‐y  data  growth   Masterpiece  of  architecture  :  R.Fielding,  REST  thesis  (2000)   Dinh&Boonkrong,  UniversityBangkok   InfoQ,  on  Linkedin  to  Node.js   MarDn  Fowler  @thoughtworks  on  microservices   Special  thanks  to  @vlavschneid,  @verseo_fr  and  the   @StreamdataIO  crew  for  supporDng  this  quest
