I want to separate my cloud into different parts, but, I'm really confused abut these concepts: region ? Cell ? availability zone ? aggregate host ?
Anyone can give me some examples about how these concepts working together in a cloud ?
Thanks -chen
Hi,
I would recommend you start by reading the "Segregating Your Cloud" section in the OpenStack Operations Guide:
http://docs.openstack.org/trunk/openstack-ops/content/scaling.html#segregate_cloud
(some basic chinese translation is here if that is useful to you : https://github.com/cloudisopen/OpenStack/blob/master/source/Architecture/Scaling.rst)
As an example, I used to work on a cloud that had 8 different data centres providing a cloud on a single API endpoint. Each datacentre was a 'cell', but within each cell could be multiple host aggregates.
Hi Chen,
For understanding the availability zone and host aggregate you may refer segregation-in-grizzly-availability-zones-versus-host-aggregates
