Re: Howto Nova setup with HA?
Thanks for your reply.
With mysql master/master i meant the following: http://mysql-mmm.org/ but it seems they are using 2 different locations for mysql reads and writes. Something nova is (yet) not able to configure (i.e. --sql_connection= which is being used for reads and rights.)
Maybe http://www.mysql.com/products/cluster/ is a better way..
RabbitMQ HA i am aware of. This is something we are looking at as well.
The main question is how does other companies reach HA with openstack? I can't find any good information on the net about it.
And how does Essex change things?

I would prefer to use MySQL Cluster:
http://www.mysql.com/products/cluster/. You meant that with MySQL
For RabbitMQ there are several ways to setup it:
I think the customer site has to decide which HA setup they want use.
All types have advantages and disadvantages.
