Hello Amit, Good questions.
I would agree that the simplest description of a public cloud is what you mention - "one that allows anyone to sign up(either freely or paid) to access the resources provided". Like amazon EC2, etc. The hybrid model mentioned is what I would describe as a private cloud that when needed can pull in or access resources of a public cloud. There do exists VCL provisioning modules in development that can request resources from EC2 and IBM's cloud. Xianqing Yu is working on a JIRA issue for interacting with an IBM cloud https://issues.apache.org/jira/browse/VCL-457 as an example.
