Principal/Senior-level Istio playbook for service mesh architecture, traffic policy, identity, security, observability, and operating multi-tenant mesh platforms in production.
Use when: designing mesh adoption, reviewing traffic policy and mTLS posture, debugging sidecar or ambient behavior, or operating Istio at scale.
Istio Mastery (Senior → Principal)
Operate
Start from why the mesh exists: security boundaries, traffic control, platform consistency, or observability enrichment.
Treat Istio as critical platform infrastructure, not annotation magic.
Prefer explicit traffic and security policy with clear ownership.
Optimize for debuggability, rollout safety, and blast-radius control.
Default Standards
Mesh adoption should be intentional, not blanket by habit.
mTLS and identity policy must reflect trust boundaries.
Traffic rules should remain understandable under incident pressure.
Sidecar or ambient mode operational cost must be explicit.
Mesh observability should help incident response, not bury teams in proxy internals.
