CERN has been running a large OpenStack private cloud in production for several
years. Services offered include virtualized compute, persistent block storage,
shared filesystems, and more recently baremetal provisioning and S3.
The existing network infrastructure has evolved in the last two decades and
although scalable (currently 10000s of physical nodes) it lacks some of the
flexibility users and external tools often rely on. These include floating and
virtual IPs, tenant networks, IP mobility, among others.
In this presentation we will describe how we've setup a new prototype region in
our private cloud offering software defined networking, relying on Tungsten
Fabric. We will present how we currently deploy the control plane using
kubernetes and helm, and some of the choices we've made regarding protocols and
configuration. We will summarize our initial use cases and finish with the next
steps towards a production setup.
