In 2016, the engineering team didn't need load balancing — they didn't have that much traffic. But once they started gaining traction, scaling and load balancing became a key concern, as did cert-rotation. It was time to adopt a service mesh.

First we evaluated Istio. But it proved to be a little too complex for us to handle. First, we had problems properly configuring Envoy. And, after updating versions [...] broke our test cluster, we decided to go for something simpler.
