The NIST definition offers cloud bursting for load balancing between clouds as an example of what?

1. Cloud bursting is named once, in a parenthetical at the very end of the deployment models section. 2. It illustrates the binding technology in the hybrid clause: technology "that enables data and application portability (e.g., cloud bursting for load balancing between clouds)". 3. So it is an example of hybrid cloud portability, the mechanism that lets work move between the distinct clouds that make up the hybrid. 4. The phrase "between clouds" is itself the clue, since only the hybrid model involves more than one cloud infrastructure. 5. Metering belongs to measured service, not to the public model isolation is implied by private but never named as a technology and the community clause names no technology at all. _Source: NIST SP 800-145 "The NIST Definition of Cloud Computing" (Sept 2011), p.3 section 2 "Deployment Models"_
