    Cloud Deployment Models

    Overview

    In this tutorial, we will learn about different cloud deployment models. Cloud Deployment Model defines the type of access to the cloud. It is characterized by the location of the cloud environment and by the type of party that has control over it.

    Cloud Deployment Models

    The four deployment models in cloud computing defined by the NIST(National Institute of Standards and Technology) are as follows:

    • Public cloud
    • Private cloud
    • Hybrid cloud
    • Community cloud

    Public cloud

    Public cloud infrastructure is provisioned for open use by the general public. It may be
    owned, managed, and operated by a business, academic, government organization, or
    some combination of them. It exists on the premises of the cloud provider.

    Private cloud

    Private cloud infrastructure is provisioned for exclusive use by a single organization
    comprising multiple consumers (e.g., business units). It may be owned, managed, and
    operated by the organization, a third party, or some combination of them, and it may exist on or off premises.

    Hybrid cloud

    The cloud infrastructure is a composition of two or more distinct cloud
    infrastructures (private, community, or public) that remain unique entities, but are bound together by standardized or proprietary technology that enables data and application portability (e.g., cloud bursting for load balancing between clouds).

    Community cloud

    The cloud infrastructure is provisioned for exclusive use by a specific
    community of consumers from organizations that have shared concerns (e.g., mission,
    security requirements, policy, and compliance considerations). It may be owned,
    managed, and operated by one or more of the organizations in the community, a third
    party, or some combination of them, and it may exist on or off premises.
