The Dark Side of Scale
summary
Argues that “scale” is often a hollow virtue and shows concrete examples: a small ag startup runs successfully on Gmail+Dropbox+laptop instead of elaborate cloud stacks, Stack Overflow operates on 34 physical servers (surprising low number for huge traffic), while the demo sockshop balloons into ~400 microservices with Prometheus, Jaeger, Weave Scope, Kubernetes, Envoy and Istio stitched together. Advocates YAGNI, a complexity/cleverness budget, and preferring simpler, debuggable deployments over prophylactic over‑engineering.
