a collection of cooperating, interoperable autonomous component clouds
- the component clouds perform their local operations (internal requests) while also participating in the federation and responding to other component clouds (external requests)
- the component clouds are autonomous in terms of, for example, execution autonomy
- execution autonomy is the ability of a component cloud to decide the order in which internal and external requests are performed
- the component clouds are loosely coupled where no control is imposed by no changes are required to participate in a federation
- also, a federation controller does not impose changes to the component cloud except for running some central component(s) of the federated system (for example, a broker agent – executes as a workload)
- also, a federation controller does not impose changes to the component cloud except for running some central component(s) of the federated system (for example, a broker agent – executes as a workload)
- the component clouds are likely to differ in, for example, infrastructure resources and their cloud platform software
- workloads may be distributed on single or multiple clouds, where the clouds may be colocated or geographically distributed
- component clouds only surface NBIs (Please note that VMware deployed in a private and a public cloud can be treated as a single cloud instance)
