Which deployment model does the NIST definition describe as provisioned for open use by the general public?

1. All four deployment models open with the same phrase, "The cloud infrastructure is provisioned for...", so the difference is in who it is provisioned for. 2. Public cloud is provisioned "for open use by the general public". 3. Private cloud is provisioned "for exclusive use by a single organization", and community cloud "for exclusive use by a specific community of consumers". Both say *exclusive*, which is the opposite of open. 4. Hybrid cloud is not provisioned for a group at all; it is "a composition of two or more distinct cloud infrastructures". _Source: NIST SP 800-145 "The NIST Definition of Cloud Computing" (Sept 2011), p.3 section 2 "Deployment Models"_
