In a public cloud, you share the same hardware, storage, and network devices with other organizations or cloud “tenants,” and you access services and manage your account using a web browser. Public cloud deployments are frequently used to provide web-based email, online office applications, storage and more.
The cloud resources (like servers and storage) are owned and operated by a third-party cloud service provider and delivered over the internet. Microsoft Azure is an example of a public cloud. MyQ Roger is a true-cloud product that runs entirely in Microsoft's public cloud Azure.
