P2P  Hidden  Costs  

Bo#om  Line  SOA    by  Marc  Rix  

Web  services  

A  web  service  does  NOT  truly  decouple  the  consumer  and  provider  

P2P  Integra-ons  

The  cost  of  maintaining  P2P  integra-ons  increases  exponen5ally  as  the  number  of  the  connec-ons  increases

ROC    plaMorm  

Netkernel  is  a  Resource-­‐Oriented  Compu-ng  (ROC)  pladorm  that  runs  within  a  Java  Virtual  Machine  (JVM)  

Transports  

Transports  are  used  to  

• Capture  external  request  or  events  • Map  request  or  event  data  to  a  logical  address  (URI)  and  ac-on  (C.R.U.D)  

• Issue  sub-­‐request  to  a  RESTful  Microkernel  

RESTful  microkernel  

The  RESTful  microkernel  

• Resolves  requests  to  the  address  space  to  physical  code  

• Schedules  request  to  run  on  available  core  allowing  processing  to  scale  linearly
