Hello everybody. I've been studying for some time now, reading official and third-party documentation about deploying and day-to-day maintenance of openstack. What I don't usually read about is the redundancy and high availability of basic services, such as the database, keystone, neutron... I wanted to better understand how it works in a small deployment scenario... I mean... 5 or 10 nodes and 3 controllers, for example... Here we use block storage fiber channel, so we won't use ceph... Of course, I won't implement it in production overnight, but I would like to hahaha but I would like to better understand this part of service redundancy. Thank you all for the emails sent every day. I learn a lot from them. -- Att, Jorge Visentini +55 55 98432-9868
