An Introduction to the Public Cloud
Public Cloud is the most recognized model of cloud computing. Here, cloud services are built utilizing shared physical resources that are pooled together and provided in a virtualized environment. These services can be accessed over a public network like the Internet. In the case of public clouds, the same shared infrastructure is used to provide services to multiple clients.
Public clouds enable the dynamic provisioning of storage and computational services on a self-service basis via web applications and services over the Internet.
Examples of the public cloud model include online software applications, cloud hosting, cloud storage services and cloud-based development environments.
