Hybrid Cloud
A computing environment that combines public and private clouds so workloads can move between them.
A hybrid cloud combines an organization’s on-premises or private cloud infrastructure with a public cloud like Azure, letting workloads and data move between them. It suits organizations that must keep regulated data on-premises while still scaling non-sensitive workloads out to Azure on demand. For the AZ-900 exam, do not confuse hybrid with multi-cloud: multi-cloud means using several public providers, whereas hybrid mixes on-premises or private infrastructure with a public cloud. Azure Arc is Microsoft’s tool for extending Azure management, governance, and Azure Policy to servers and Kubernetes clusters running outside Azure, enabling a consistent hybrid strategy.
