<title>Compute focused</title>
<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>High performance computing (HPC)</para>

<para>Big data analytics using Hadoop or other distributed data
stores</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>
