Deep dive: Linux networking
SCaLE 22x, Pasadena, CA
Mohamed Elsakhawy, Ph.D
My research interests lie in the broad spectrum of Cloud Computing with a particular focus on data-driven intelligence for the Cloud. I am interested in investigating how the vast amount of operational data generated by production Clouds can be leveraged to guide the decision-making process in these Clouds.

How packets actually flow in OpenStack
A six-part walk through the Neutron data path — from a VM's virtual NIC, across bridges and tunnels, to the wire and back. Read in order; each part assumes the one before it.
6 partsRunning Ceph behind OpenStack
Operational notes from a production Ceph cluster backing Cinder, Glance and Nova — growing it, snapshotting it, unsticking it, and eventually deploying it with cephadm.
6 partsNeutron internals and gotchas
Standalone deep dives into the parts of Neutron that bite you in production: VNI ranges, port security, external networks and SR-IOV passthrough.
