LinkedIn Draft — Workflow (2026-03-31) This pattern has saved production twice in the last year: Service mesh adoption: the operational debt lands before the value does Service meshes promise mTLS, traffic splitting, and deep observability. What arrives first is a new category of production failures your team has never debugged before. Adoption curve reality: Value │ ╱ mTLS + traffic control │ ╱ │ ╱╲ complexity trough │ ╱╲╱ │ ╱╲╱ ← sidecar failures, upgrade pain │╱ └──────────────────────────────▶ Time Week 1 Month 3 Month 9 Where it breaks: ▸ Sidecar injection failures look like app bugs — hours spent debugging the wrong layer. ▸ mTLS policy rollout in a live cluster requires namespace-by-namespace phasing — one mistake stops traffic. ▸ Mesh upgrades require coordinated sidecar restarts across the cluster — on large deployments, that's everything. The rule I keep coming back to: → Start mesh in observability-only mode (no policy enforcement). Prove value in one namespace first. Earn t
