Cloud deployment models define the specific type of cloud environment based on who owns the infrastructure, who has access to the data, and whether the resources are shared or dedicated. The choice of deployment model significantly impacts factors like security, control, scalability, and cost. Here are the main cloud deployment models: Public Cloud: Description: Cloud services are offered by third-party providers (like AWS, Microsoft Azure, Google Cloud Platform) over the public internet. Resources (servers, storage, networks, applications) are shared among multiple users or "tenants." Private Cloud: Description: The cloud infrastructure is dedicated exclusively to a single organization. It can be hosted on-premises within the organization's own data center or by a third-party provider that ensures dedicated resources. Hybrid Cloud: Description: A combination of two or more distinct cloud infrastructures (private cloud and public cloud) that remain unique entities but are bound together by standardized technology. This allows data and applications to be shared between them. Community Cloud: Description: The cloud infrastructure is shared by several organizations that have common concerns (e.g., security requirements, compliance considerations, or specific mission). It can be managed internally by one or more of the organizations or by a third party.
