Technology Short Take 95

Welcome to Technology Short Take 95! This Short Take was a bit more challenging than normal to compile, given that I spent the week leading up to its publication visiting customers in Europe. (My travel schedule in Europe is also why it didn’t get published until Saturday instead of the typical Friday.) Nevertheless, I have persevered in order to deliver you this list of links and articles. I hope it proves useful!


  • Larry Smith Jr. has a nice write-up on Cisco XR stemming from a presentation at NFD 17.
  • VMware recently released a reference design guide for NSX-T; see here for more details.
  • The engineering team at Lyft recently discussed a new overlay-free networking approach they’ve been working on for Kubernetes: IPVLAN-based CNI stack for running within VPCs on AWS. This is pretty cool, but does introduce some potential design considerations for deploying Kubernetes on AWS. (For those that may be unfamiliar: CNI, or Container Network Interface, is the means whereby network mechanisms “plug into” Kubernetes. IPVLAN is a low-latency means of providing IP connectivity to containers. VPCs, or Virtual Private Clouds, are Amazon’s software-defined networking mechanism for workloads running on AWS.)
  • Viktor van den Berg writes on deploying NSX load balancers with vRA.
  • Alen Komljen provides an introductory overview of service meshes in Kubernetes.
  • Matt Klein has a great post on why we need to embrace eventual consistency in (distributed) networking.
  • In the event that you need yet-another-introduction to Kubernetes networking, Mark Betz has a three-part series you may find helpful/useful (part 1, part 2, and part 3).


Nothing this time around, sorry!


  • This doesn’t make me feel very secure.

Cloud Computing/Cloud Management

Operating Systems/Applications


  • I had a chance to take a (very) quick look at Dotmesh, a new solution that enables snapshots for stateful workloads in Kubernetes and Docker. It seems like an interesting and potentially helpful solution, although I haven’t (yet) had the time to actually spend any hands-on time with it.


Career/Soft Skills

Nothing this time around (which surprises me—I almost always find material to include in this section).

OK, that’s all this time around, but I’ve already started gathering material for next time. Look for the next Technology Short Take in about two weeks. Thanks for reading!
