SREcon19 Asia/Pacific - Software Networking and Interfaces on Linux

Matt Turner, Native Wave These are the days of VMs, containers, and service meshes. The network, for a long time the sysadmin's mysterious domain, is now at the forefront: providing overlays, security features, and headaches. It's vital to be able to understand what's going on under the hood of a cloud-native platform if you ever hope to debug it, but do you know a TAP from a TUN, let alone an ipvlanL3? This talk will take you through all the network interface types on modern Linux, from good old eth0 to the vEths used by Docker and the tunnels used by Calico.
