But as we’ve seen repeatedly over the last few years, the excitement about service mesh has been tempered by practical additional overhead. Let’s explore how Envoy or wrote about his experiences configuring Istio to reduce consumption from around 1GB per proxy (!) to a much more reasonable 60-70MB each. But even in our Continue reading
