I have an openstack deployment question. I have three physical<br>
server(Configurations are listed in the following). What is the best<br>
optimized production-ready deployment model to achieve the following<br>
goals in mind(Users will not exceeds more than 10)?<br>
- Ability to add more services(compute, controller, storage node)<br>
later, without service interruption<br>
- Ability to provide HA for all services, after more nodes added<br>
without service interruption<br>
- No need to change the deployment architecture later when more<br>
physical nodes and resources available(My physical infrastructure will<br>
be scaled later, and not limitted to these three physical machines).<br>
For example I don't know is it better to have 1 neutron node, or have<br>
two neutron service on my two compute nodes?<br></blockquote><div><br></div></span><div>Hi - Have you read:</div><div><a href="http://docs.openstack.org/openstack-ops/content/scaling.html" target="_blank">http://docs.openstack.org/openstack-ops/content/scaling.html</a><br></div><div><br></div><div>and</div><div><br></div><div><a href="http://docs.openstack.org/openstack-ops/content/example_architecture.html#example_architecture-neutron" target="_blank">http://docs.openstack.org/openstack-ops/content/example_architecture.html#example_architecture-neutron</a><br></div><div><br></div><div>Horizontal scaling is covered in these as well as your neutron question.</div><span class="HOEnZb"><font color="#888888"><div><br></div><div>Anne</div></font></span><span class=""><div><br></div><div> </div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left-width:1px;border-left-color:rgb(204,204,204);border-left-style:solid;padding-left:1ex">
