Now that you've made your decision, I'd like to ask some followup questions for my own decision if I may. Most everyone have talked about some kind of load balancer or HA solution. My setup is such that that wouldn't be .. "workable". My whole Openstack setup is installed on a HP Bladecenter with 16 half hight nodes so all communication etc is pretty much internal in the blade center. I.e, the only external link is the one to the rest of the flat and then to the gatway/firewall/NATbox. Also, having a LB in front of MySQL (and possibly one more in front of Keystone), that will introduce a "single point of failure" that I'd prefer not to have (even if it was practically possible - I don't want to dedicate a whole BC node just for that, they're to precious). What would be the impact and/or problem by using DNS round robin for MySQL and Keystone for example? And then have MySQL in a master-master setup. I've never done that either, so I'm not sure how good idea that would be.. Any pointers? The only DB I've ever had the .. "displeasure" to try to get to work in a master-master setup is OpenLDAP and I can remember (vividly!) the discussions that's been on the OpenLDAP lists about this over the years! In essence, "don't, for the love of whoever, do it!!". -- Choose a job you love, and you will never have to work a day in your life. _______________________________________________ Mailing list: http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack Post to : [email protected] Unsubscribe : http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack
