Different Types of Cloud Computing Models

Private Cloud A private Cloud refers to a cloud infrastructure dedicated solely to one organization. It can be hosted on-premises or by a provider. The resources of a private cloud are not shared with other organizations, providing greater control, security, and customization options. The private cloud is suitable for organizations with strict security and compliance requirements, or those that require high levels of control over their infrastructure.

Public Cloud A Public Cloud refers to a cloud infrastructure owned and operated by a third-party cloud service provider, such as AWS, Microsoft Azure, or GCP. The resources of a public cloud are shared among multiple organizations providing scalability, flexibility, and cost effectiveness. Public Clouds offer a wide range of services and are suitable for organizations of all sizes, including start-ups, enterprises, and government agencies.

Hybrid Cloud This is a combination of private and public cloud infrastructure, interconnected to enable data and applications portability between the two environments. An organization can use a hybrid cloud to leverage the benefits of both private and public clouds, such as the security and control of a private cloud and the scalability and cost-effectiveness of a public cloud. Hybrid Clouds are suitable for organizations that have varying workload requirements, regulatory constraints, or legacy systems that can not be migrated to the public cloud.
