Public Cloud

A public cloud is a type of cloud computing service that delivers computing resources, such as virtual machines, storage, and networking, over the internet to a wide range of users.

In a public cloud, the infrastructure is owned, operated, and maintained by a third-party cloud service provider. These cloud providers make resources available to the public on a pay-as-you-go or subscription basis.
