Explain Cloud Deployment Models
Cloud Deployment Models:
The cloud model is invented with four deployment models:
- Public cloud
- Private cloud
- Hybrid cloud
- Community cloud
A majority of companies concentrate on controlling the cloud to reduce capital expenses and manage operating expenses. Models have been suggested by the National Institute of Standards and Technology (NIST). As per NIST, the following are the deployment models.
The cloud infrastructure is provisioned for open use by the general public. It may be owned, managed and operated by a business, academic or government organization or some combination of them. It exists on the premises of the cloud provider.
Cloud infrastructure is provisioned for exclusive use by a single organization comprising multiple consumers. It may be owned, managed and operated by the organization, a third party or a combination of them. It may exist on or off-premises.
The cloud infrastructure is a composition of two or more distinct, cloud infrastructures that remain unique entities but are bound together by standardized or proprietary technologies that enable data and application portability.
The Cloud infrastructure is provisioned for exclusive use by a specific community of consumers from organizations that have shared concerns. It may be owned, managed and opened by one or more of the organizations in the community, a third party or a combination of them. It may exist on or off-premises.
