Here’s a quick look at using Envoy as a load balancer in Kubernetes. Via Alex Mitelman’s Systems Design Weekly 015 , I was pointed to this AWS article on multi-site active-active architectures. It’s a good starting point for thinking about operating your own active-active architecture. Virtualization.

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. Operating Systems/Applications. Virtualization. Unfortunately, this appears to be GKE-specific.

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. (For VPCs, or Virtual Private Clouds, are Amazon’s software-defined networking mechanism for workloads running on AWS.). Virtualization.
