All this by directly tapping into the OpenStack message bus for processing critical events in real-time. Schlagwörter: billing, charging, Cyclops, events, nova, openstack, RabbitMQ, rating
In our previous blog post we presented an overview of Nova Cells describing its architecture and how a basic configuration can be set up. After some further investigation it is clear why this is still considered experimental and unstable; some basic operations are not supported as yet e.g. floating ip association as well as inconsistencies […]
In the GEYSER project, we are examining suitable Openstack architectures for our pilot deployments. In an earlier blog post we described different ways to architect an Openstack deployment mostly focusing on AZ (Availability Zone) and Cells (those were the only options available back in 2013). Much has changed since then and new concepts were added […]

Recently we had to remove a compute node in our cluster for management reasons (read, it went dead on us). But nova perpetually maintains the host entry hoping at some point in time, it will come back […]
