|
|
<para>A compute-focused cloud is a specialized subset of the general purpose
|
|
OpenStack cloud architecture. Unlike the general purpose OpenStack
|
|
architecture, which hosts a wide variety of workloads and
|
|
applications and does not heavily tax any particular computing aspect,
|
|
a compute-focused cloud specifically supports
|
|
compute intensive workloads. Compute intensive
|
|
workloads may be CPU intensive, RAM intensive, or both; they are
|
|
not typically storage intensive or network intensive. Compute-focused
|
|
workloads may include the following use cases:</para>

|
|
<para>Based on the use case requirements, such clouds might need to provide
|
|
additional services such as a virtual machine disk library, file or object
|
|
storage, firewalls, load balancers, IP addresses, or network connectivity
|
|
in the form of overlays or virtual local area networks (VLANs). A
|
|
compute-focused OpenStack cloud does not typically use raw block storage
|
|
services as it does not generally host applications that require
|
|
persistent block storage.</para>
