Cloud topology example
|
|
======================
|
|
|
|
.. note::
|
|
|
|
The information on this page is associated with the topic of :ref:`Managing
|
|
Power Events <managing_power_events>`. See that page for background
|
|
information.
|
|
|
|
This page contains the analysis of cloud machines. The ideal is to do this for
|
|
every machine in a cloud in order to determine the *cloud topology*. Six
|
|
machines are features here. They represent a good cross-section of an *Ubuntu
|
|
OpenStack* cloud. See :ref:`Reference cloud <reference_cloud>` for the cloud
|
|
upon which this exercise is based.
|
|
|
|
Generally speaking, the cloud nodes are hyperconverged and this is the case for
|
|
three of the chosen machines, numbered **17**, **18**, and **20**. Yet this
|
|
analysis also looks at a trio of nodes dedicated to the `Landscape project`_:
|
|
machines **3**, **11**, and **12**, each of which are not hyperconverged.
|
|
|
|
.. note::
|
|
|
|
Juju applications can be given custom names at deployement time (see
|
|
`Application groups`_ in the Juju documentation). This document will call
|
|
out these `named applications` wherever they occur.

In this example, ``mysql`` and ``nova-compute-kvm`` are `named

``percona-cluster`` and ``nova-compute``, respectively.

along with their HA status and machine type:
