A :term:`hybrid cloud` design is one that uses more than one cloud.
|
|
For example, designs that use both an OpenStack-based private
|
|
cloud and an OpenStack-based public cloud, or that use an
|
|
OpenStack cloud and a non-OpenStack cloud, are hybrid clouds.
|
|
|
|
:term:`Bursting <bursting>` describes the practice of creating new instances
|
|
in an external cloud to alleviate capacity issues in a private cloud.
|
|
|
|
**Example scenarios suited to hybrid clouds**
|
|
|
|
* Bursting from a private cloud to a public cloud
|
|
* Disaster recovery
|
|
* Development and testing
|
|
* Federated cloud, enabling users to choose resources from multiple providers
|
|
* Supporting legacy systems as they transition to the cloud
|
|
|
|
Hybrid clouds interact with systems that are outside the
|
|
control of the private cloud administrator, and require
|
|
careful architecture to prevent conflicts with hardware,
|
|
software, and APIs under external control.
|
|
|
|
The degree to which the architecture is OpenStack-based affects your ability
|
|
to accomplish tasks with native OpenStack tools. By definition,
|
|
this is a situation in which no single cloud can provide all
|
|
of the necessary functionality. In order to manage the entire
|
|
system, we recommend using a cloud management platform (CMP).
|
|
|
|
There are several commercial and open source CMPs available,
|
|
but there is no single CMP that can address all needs in all
|
|
scenarios, and sometimes a manually-built solution is the best
|
|
option. This chapter includes discussion of using CMPs for
|
|
managing a hybrid cloud.
