We love tests at Twingate. When working on the Twingate’s helm charts repository I wanted to incorporate testing like we do with other code. For a long time our release process requires a long process of manual testing - every change to the chart’s templates required a manual process of testing the chart with various inputs to make sure it still works as expected. Enter golden tests as a way to automate this process…

We recently switched to Twingate’s GKE load balancer to use Google’s new Container-native load balancer. The premise was good - LB talks directly to pods and saves an extra network hops, (with classic LB, traffic goes from LB to a GKE node which then, based on iptables configured by kube-proxy, get routed to the pod) and should perform better, support more features, and in general we’d rather be on google’s maintained side and not on legacy tech.

One of the most important aspects of building your own analytics system is how you store the data and expose it for querying. This post describes the challenges and approach taken when designing the analytics system for dapPulse (now monday.com) and later at Wondermall.
