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

1060 Research NetKernel
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
NetKernel Middleware Server
Transports HTTP, JMS, FTP
Logical Address Space URI

Physical Code (Java, Groovy, Scala)
