What kind of architecture does a hybrid cloud offer organizations?

A combination of virtualized servers describes a virtualization infrastructure or private cloud implementation, not a hybrid cloud, which specifically requires the presence of a public cloud component.

A combination of serverless computing and public cloud services describes a subset of public cloud service types rather than the defining characteristic of hybrid cloud, which requires private infrastructure.

Hybrid cloud is defined by the integration of privately owned and operated infrastructure - whether on-premises data centers or a private cloud - with public cloud services from providers like Google Cloud, AWS, or Azure. This combination allows organizations to keep sensitive workloads on private infrastructure while leveraging the scalability and services of the public cloud, with data and applications portable between the two.

A combination of multiple public cloud providers describes a multi-cloud architecture, which is distinct from hybrid cloud because it does not include private on-premises or private cloud infrastructure.
