Mobile First

  • We are not a port from a PC program
  • No shoehorning to mobile
  • No legacy code or designs to deal with
  • Our DNA is mobile/embedded
  • We push the envelope on available tech & tools
  • We think mobile, i.e. limited resources:
  • Connectivity/network
  • Battery life
  • CPU
  • Storage

Cross Platform Architecture

11

  • Our clients share the bulk of the code
  • Lots of code reuse ( dev. efficiency)
  • Easy to port to new platforms
  • Feature parity
  • Enables automated testing
  • But…
  • Complex build
  • Tricky cross language boundary crossing code

Smart Client

12

  • Realizations
  • There will always be more clients than servers
  • We will scale better if clients can “pull their own weight”
  • Need good UX even if servers aren’t reachable
  • Build Sophisticated Client
  • Offload as much as possible from servers
  • Cache heavily for UX
  • We are not just an HTML app (people tried & failed)
  • Create custom protocols
  • Downside: Complexity (versioning, c2c, c2s)

Future Areas of Exploration

  • Reliability testing for ‘real world’ client to server

craziness

  • Clients pointing to servers that have simulated latency

/failures

  • Simulated clients that behave like real world
