Types of Cloud Computing
Cloud computing can be categorized into three main types: public cloud, private cloud, and hybrid cloud.
- Public Cloud: Public cloud refers to a cloud computing model where a third-party cloud provider owns and manages the cloud infrastructure, making it accessible to the general public via the internet. Well-known public cloud services are offered by providers like Amazon Web Services (AWS), Microsoft Azure, and Google Cloud Platform (GCP).
- Private Cloud: On the other hand, a private cloud is a cloud computing model where a single organization owns and operates the cloud infrastructure exclusively for its users. The private cloud can be hosted either on-premises within the organization’s facilities or in a third-party data center.
- Hybrid Cloud: A hybrid cloud is a combination of public cloud and private cloud usage. This model allows organizations to leverage the advantages of both public and private clouds. For instance, an organization might use a public cloud for web hosting while keeping sensitive data on a private cloud for enhanced security and control.
Characteristics of Cloud Computing
Cloud computing is defined by several distinct characteristics that set it apart from traditional computing models.
