A private cloud consists of cloud computing resources used exclusively by one business or organization.
It can be physically located at your organization’s on-site data centre, or it can be hosted by a third-party service provider. The services and infrastructure are always maintained on a private network and the hardware and software are dedicated solely to your organization. This make it easier for an organization to customize its resources to meet specific IT requirements.
Public clouds are the most common type of cloud computing deployment. The cloud resources (servers and storage) are owned and operated by a third-party cloud service provider and delivered over the internet. With a public cloud, all hardware, software, and other supporting infrastructure are owned and managed by the cloud provider. Public cloud deployments are frequently used to provide web-based email, online office applications, storage, and testing and development environments.
A hybrid cloud is a type of cloud computing that combines on-premises infrastructure—or a private cloud—with a public cloud. Hybrid clouds allow data and apps to move between the two environments. Organizations choose hybrid cloud due to business imperatives such as meeting regulatory and data sovereignty requirements, taking full advantage of on-premises technology investment, or addressing low latency issues.
