Kubernetes Efficiency
Kubernetes saturation pass
Node group review, request/limit drift checks, and scheduler hints that recover headroom without heroic re-architecture.
What the briefing covers
We profile burst patterns, spot placement safety, and daemon overhead. The pass ends with a concise patch list your cluster operators can execute in ordinary sprints.
Feature checklist
- Scheduler profile snapshot across production pools
- Right-size suggestions grounded in observed percentiles
- Spot / on-demand mix review with guardrails
- Addon overhead audit (mesh, logging, security agents)
- HPA coverage map versus actual traffic ramps
- Image pull and registry latency notes
- Operator-friendly backlog grouped by blast radius
Outcomes
- Documented headroom targets per pool with safety notes
- Shared language between SRE and application teams on limits
- A two-sprint patch list with owners attached

FAQ
Preferably we reuse existing observability; if gaps exist we propose lightweight exporters rather than new paid stacks.
Desk notes from teams
The Kubernetes saturation pass surfaced three daemonsets we could demote safely. The limitation call-out on legacy JVM heaps saved us from a risky resize.
