This allows users to access these resources from anywhere, at any time, as long as they have an internet connection.
Public Clouds
A public cloud is a cloud computing infrastructure that is owned and operated by a third-party provider. Public clouds are typically open to the general public and are accessible through the internet. They are often used by large enterprises and organizations that require a high level of scalability, security, and reliability.
