Sync is the Future of Mobile Data

Couchbase Mobile is an open-source data synchronization system for occasionally connected devices like smartphones, tablets, and desktop computers. Our killer feature is streaming data sync, so your user experience isn't held hostage to unpredictable network performance anymore. Our sync protocol has been proven in production for over four years, and our database is written from the ground up to be lightweight and embedded in mobile apps.

7. Faster  is  BeDer
   • “Half  a  second  delay  caused  a  20%  drop  in  
   traffic.”
   – h:p://glinden.blogspot.com/2006/11/marissa-­‐mayer-­‐at-­‐web-­‐20.html
   • “Google  Search  found  that  a  400  millisecond  
   delay  resulted  in  a  -­‐0.59%  change  in  
   searches/user.  What's  more,  even  aMer  the  
   delay  was  removed,  these  users  sNll  had  
   -­‐0.21%  fewer  searches,  indicaNng  that  a  
   slower  user  experience  affects  long  term  
   behavior.”  –  Steve  Souders

9. Fallacies  of  Distributed  CompuHng
   ? • The  network  is  reliable.
   • Latency  is  zero.
   • Bandwidth  is  infinite.
   • The  network  is  secure.
   • Topology  doesn’t  change.
   • There  is  one  administrator.
   • Transport  cost  is  zero.

10. Take  the  Cloud  Out  of  the  CriHcal  Path
    • Local  data
    • Predictable  latency
    • App  works  offline
    • Cloud  services  can  be  
    tuned  for  throughput
    • Developers  control  the  
    user  experience
    • Mobile  apps  can  address  
    new  use  cases
