Hybrid cloud describes the use of private and public cloud platforms, along with on-premises IT infrastructure. It can refer to any combination of cloud solutions and in-house IT. Companies use hybrid cloud to quickly and cost-effectively enhance their existing resources. They can keep sensitive data secure within a private cloud and also quickly add more computing, network bandwidth or storage in a third-party public cloud to address temporary surges in demand.
Hybrid cloud can also refer to a single solution that incorporates multiple cloud platforms. In this case, there is a single management system to access and operate all the cloud elements.
