About Microservices, Containers and their Underestimated Impact on Network Performance
shock horror, Docker-SDN layers have terrible performance. Still pretty lousy perf impacts from basic Docker containerization, presumably without "--net=host" (which is apparently vital)

Google Cloud Platform Blog: A look inside Google’s Data Center Networks
We used three key principles in designing our datacenter networks:
We arrange our network around a Clos topology, a network configuration where a collection of smaller (cheaper) switches are arranged to provide the properties of a much larger logical switch.
We use a centralized software control stack to manage thousands of switches within the data center, making them effectively act as one large fabric.
We build our own software and hardware using silicon from vendors, relying less on standard Internet protocols and more on custom protocols tailored to the data center.

Snabb Switch
an open source virtualized Ethernet networking stack.

I am developing Snabb Switch in response to several exciting trends:
x86 has risen to be a powerful networking platform.
Virtualization and SDN are pulling more networking into servers.
Optimized user-space software is out-performing kernel-space software.

Snabb Switch's simple and fast software-only data plane makes developing networking software easier than ever before.


Written in LuaJIT but aiming to be very fast. cool stuff, worth watching
