Which one is not a cloud deployment model ?
(a) Public
(b) Private
(c) organization
(d) Hybrid
The correct answer and explanation is:
The correct answer is (c) organization.
Cloud computing deployment models refer to how and where cloud services are implemented, managed, and accessed. These models dictate how resources are shared, controlled, and allocated. The major cloud deployment models are:
- Public Cloud: In a public cloud, cloud resources such as servers and storage are owned and managed by a third-party cloud service provider. These resources are made available to the general public or a large industry group. Public clouds are typically used for applications where security and privacy concerns are minimal, and cost-effectiveness is a priority. Services like Google Cloud, Microsoft Azure, and AWS (Amazon Web Services) fall under this category. Public cloud services are often used for hosting websites, testing new applications, and software development.
- Private Cloud: A private cloud is dedicated to a single organization. It can either be hosted on-site at the organization’s data center or managed by a third-party provider. Unlike public clouds, private clouds are highly secure and tailored to meet specific organizational requirements, such as compliance with regulations or the need for a customized IT infrastructure. The private cloud gives the organization greater control over its data and security.
- Hybrid Cloud: A hybrid cloud combines the features of both public and private clouds. It allows data and applications to be shared between them, enabling businesses to take advantage of the scalability and cost-effectiveness of the public cloud while maintaining the security and control offered by a private cloud. A hybrid cloud is particularly useful for businesses that need to keep some data on-premises due to compliance, privacy, or regulatory requirements, while still benefiting from the flexibility and cost savings of public cloud services.
- Organization: This is not a recognized cloud deployment model. It may be used in certain contexts to describe a specific entity or business using the cloud, but it doesn’t refer to a deployment model itself. The three primary models are public, private, and hybrid clouds.
Understanding these deployment models helps businesses choose the right infrastructure based on their needs for scalability, security, and cost. Each model offers different levels of control, cost, and management complexity.
