Cloud deployment public model – UGC NET Question

A public cloud is operated by a third party provider and delivers computing resources over the internet to multiple customers, making services broadly available to the general public on subscription or pay per use. Since the institution is using services open to the public via the internet, it is a public cloud.

Option A:
Option A is correct because a public cloud offers services such as storage, computing and applications to anyone over the internet on a pay per use or subscription basis. The institution is just one of many customers. Public clouds are managed by third party providers like major cloud vendors.

Option B:
Option B, private, cloud is restricted to a single organisation and not open to the general public, so it contradicts the description in the stem. Private clouds are usually implemented within an organisation’s own data centre or on dedicated infrastructure. Thus, this term does not correctly fill the blank.

Option C:
Option C, community, cloud is shared by a specific group of organisations with common concerns, such as security or mission, and is not generally available to the public. This makes it unsuitable as an answer to the scenario given.

Option D:
Option D, hybrid, cloud combines two or more cloud models, typically public and private, with data and application portability between them. The question does not mention such a combination, so hybrid cloud is not the best match.
