<title>General purpose</title>
|
|
<para>An OpenStack general purpose cloud is often considered a
|
|
starting point for building a cloud deployment. They are designed
|
|
to balance the components and do not emphasize any particular aspect
|
|
of the overall computing environment.
|
|
Cloud design must give equal weight to the compute, network, and
|
|
storage components. General purpose clouds are
|
|
found in private, public, and hybrid environments, lending
|
|
themselves to many different use cases.

|
</para>
|
|
<note>
|
|
<para>
|
|
General purpose clouds are homogeneous deployments and are
|
|
not suited to specialized environments or edge case situations.

<para>Use cases that benefit from scale-out rather than scale-up approaches
|

are good candidates for general purpose cloud architecture.

</para>
|
|
<para>A general purpose cloud is designed to have a range of potential
|
|
uses or functions; not specialized for specific use cases. General
|
|
purpose architecture is designed to address 80% of potential use
|
|
cases available. The infrastructure, in itself, is a specific use case,
|
|
enabling it to be used as a base model for the design process.
|
|
General purpose clouds are designed to be platforms that are suited
|
|
for general purpose applications.</para>
|
|
<para>General purpose clouds are limited to the most basic
|
|
components, but they can include additional resources such
