Xavier Avrillier walks readers through using Antrea (a Kubernetes CNI built on top of Open vSwitch—a topic I’ve touched on a time or two) to provide on-premise load balancing in Kubernetes. Matt Oswalt takes readers though a fairly in-depth look at sockets and address binds in Linux. Virtualization.

In the private sector, IT can set up a self-provisioning environment that lets development teams move at the required speed without ceding control of enterprise resource management – things such as compute, storage, and random access memory (RAM). Additionally, how one would deploy their application into these environments can vary greatly.

The “TL;DR” for those who are interested is that this solution bypasses the normal iptables layer involved in most Kubernetes implementations to load balance traffic directly to Pods in the cluster. Virtualization. Fortunately, the diagrams illustrate that there is something substantive behind the headline.

Open Virtual Network (OVN) is really ramping up and getting lots of attention, which I personally think is absolutely well-deserved. Linux network namespaces is a topic I’ve covered here before , but it’s always great to have multiple viewpoints and explanations of technologies and concepts to get a complete and comprehensive view.

The first concept that Recep discusses is network virtualization. He believes that network virtualization is primarily about decoupling network services from the underlying network infrastructure. The specific terminology involved is that the virtual switches become a VTEP, a virtual tunnel end-point.
