Open Stack

Hi Christian,

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?

Best regards,

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