REST

Representational State Transfer

  • All interactions (messages) with the

SURFmedia Core platform are done with REST

  • calls.
  • REST strictly refers to a collection of

network architecture principles which

  • utline how resources are defined and

addressed.

  • REST is a Client-server, Stateless,

Cacheable and Layered protocol.

  • Reduction of complexity,

improvement of performance and scalability.
