public cloud

A form of cloud computing in which a company relies on a third-party cloud service provider for services such as servers, data storage and applications, which are delivered to the company through the Internet. A public cloud can free companies from the potentially expensive costs of having to purchase, manage and maintain on-premises hardware and software infrastructure.

Public clouds can also typically be deployed much faster and with more scalability and accessibility than on-premises infrastructure as a result of the public cloud provider’s expertise and existing infrastructure. Public cloud subscribers may pay pay-as-you-go fees or fixed monthly fees for the public cloud services they utilize.
