You probably imagine scaling a Service Mesh is as smooth as scaling a Kubernetes cluster. From one node on your laptop to hundreds of nodes in a datacenter. In the beginning everything seems fine, but you might wake up one day, look at the metrics and see that the Envoy sidecar is consuming 8GBs of memory and 30% of the CPU. What on earth happened there? Well your system grew, but the Mesh grew even bigger. In this talk Krzysztof will go over algorithms that allow delivering incremental config updates (delta-xds, on-demand-xds) and explain why big systems that use “state of the world updates” cause Envoy to grow that big. Then he will focus on what can be done to improve the situation on the Control Plane and Envoy level and what is currently available in the off the shelf open source Service Meshes like Kuma, Istio, Consul.
