Featured Cloud Deployment Models

Cloud Deployment Models:

  • Public
  • Private
  • Hybrid
  • Community
  • Multicloud

Private Cloud: A private cloud, also known as internal or corporate cloud, is a cloud infrastructure that a single organization operates solely. The organization can implement the private cloud within a corporate firewall. Organizations deploy private cloud infrastructures to retain full control over corporate data. There is only a single tenant.

Public Cloud: In this model, the provider makes services such as applications, servers, and data storage available to the public over the Internet. In this model, the cloud provider is liable for the creation and constant maintenance of the public cloud and its IT resources. It is multitenant. There is public access to the service and the cloud infrastructures is shared among different organizations and individuals.

Community Cloud: It is a multi-tenant infrastructure shared among organizations from a specific community with common computing concerns such as security, regulatory compliance, performance requirements, and jurisdiction. The access is restricted to a community that meets some requirements, for example, same industry or same organization type.

Hybrid Cloud: It is a cloud environment comprised of two or more clouds (private, public, or community) that remain unique entities but bound together for offering the benefits of multiple deployment models.

Private or hybrid cloud makes sense when there are compliance requirements that compels to use it.

In a multicloud model, an organization or individual uses many cloud providers.
