A public cloud supports multiple customers.
Connectivity occurs through the Internet or virtual private connections.
Use of a public cloud is billed based on usage.
Applications are deployed on the infrastructure hardware and services
offered by the cloud provider. The user is responsible for security and
application operations but not responsible for hardware maintenance.Figure 13-4 Public Cloud
Hybrid Cloud
A hybrid cloud is composed of one or more cloud
deployment models (private and public, for example)
and is used to extend capabilities or reach and/or to
augment capacity during peak demand periods (see
Figure 13-5). The key characteristics of a hybrid cloud are
as follows:
A hybrid cloud is a combination of public and private models.
A hybrid cloud has on-premises and off-premise resources.
Orchestration between the parts of a hybrid cloud is the responsibility
of the application owner.
Applications are deployed in a distributed fashion, with some services
and components residing on premises and others (such as client access)
in the cloud provider’s environment.
