Introduction to BGP and cloud networking

This post is intended for people that is just entering to BGP and cloud networking (i.e. SDN). We’ll bring an introduction to BGP fundamental concepts.  BGP is fundamental for SDN to scale out large networks in the Datacenter for end-points attached to containers and virtual servers.
