Private cloud:
A private cloud is a cloud computing environment that is hosted on-premises by an organization. This means that the hardware, software, and networking infrastructure that supports the private cloud is owned and operated by the organization.Ex: VMware
Public Cloud:
A public cloud is a cloud computing model in which the hardware, software, and networking infrastructure are owned and operated by a cloud service provider and made available to the general public over the internet. Ex. AWS
Hybrid cloud:
A hybrid cloud is a cloud computing environment that combines a private cloud with a public cloud. This means that some workloads are hosted on-premises in the private cloud, while other workloads are hosted in the public cloud.
[Note:] AWS can be used to create hybrid cloud environments. This means that AWS resources can be combined with on-premises resources to create a single, cohesive IT environment.
