Ship ai Safely With 38% Fewer Incidents

Tactics we actually use, with configs you can copy-paste.

Start With A Boring Win, Not Demos

Let’s start by admitting what we all know: the most dramatic AI demos rarely survive first contact with real systems. We’ve had the best luck by picking a narrow, boring use case and squeezing it for measurable value. Think summarizing noisy alerts into crisp, actionable tickets, not building a robo-CIO. Boring wins are measurable, reversible, and easy to explain. We define a single “happy path” for inputs, set guardrails for everything else, and agree on success in concrete terms—minutes saved per ticket, reduction in escalations, or fewer social-engineering-prone handoffs. This keeps us from chasing novelty and helps the rest of the org trust the thing we built. That trust matters when the occasional “AI said something weird” incident appears, because we can actually quantify the tradeoffs instead of shrugging and promising vibes.

We also pin the operational constraints early. What’s the worst thing the system can do? Leak a secret, file a wrong ticket, over-ping on-call? We write those down, decide how we’ll detect them, and add a kill switch. Importantly, the kill switch has a boring owner and a documented path to rollback. We do this before we ship so nobody is arguing during an incident. It’s not glamorous, but it’s the difference between a weekend saved and a weekend ruined. When we’ve nailed one boring win end-to-end, we reuse the same playbook for the next case, gradually expanding scope with the same confidence. Small scope, fast feedback, tight rollback: that’s where compounding value lives.

Data Plumbing Beats Model Magic

The unsexy secret of useful AI is clean data with durable semantics. If we can’t trust the input, we won’t trust the output—no matter how capable the model. So we invest early in schema hygiene, lineage, and reproducibility. We version the “contracts” between producers and consumers, and we write tests around them. A log line with a missing user_id or a timestamp that’s local instead of UTC will quietly hollow out your evaluation metrics. We learned to treat features as first-class assets: documented, discoverable, and testable. Data scientists move faster when they don’t have to reverse-engineer what “priority_level” meant in Q4 two years ago.

We also put guardrails around personally identifiable information and ephemeral secrets. If your prompt or features can accidentally include tokens from a debug log, you’ve built a quiet data breach machine. We add deterministic redaction at the edge, then test the redaction like any other library. When outputs are stored, we attach provenance: which model, which parameters, which upstream dataset versions. That makes audits and rollbacks sane instead of forensic archaeology by Slack thread.

To enforce the hygiene, we rely on lightweight validation in the pipeline. Expectation tests on critical tables catch drift early and loudly. Tools like Great Expectations are helpful precisely because they make intent explicit—“this column is never null, this value is always one of these enums”—and then keep us honest as upstream teams evolve. We’d rather fix a failing expectation in staging at noon than explain a bizarre production outlier at 3 a.m.

Guardrails You Can Read: Policies And Kill Switches

We don’t rely on vibes for safety; we codify it. Before we ship an ai-powered feature, we write the safety rules as policies the cluster can enforce. Two categories pay off fast: provenance (only run images from our registry with signed tags) and traceability (no deployment without an owner and escalation path). We like policies we can show to security with a straight face and to engineers without rolling eyes—simple, declarative, and enforced the same way across services.

Here’s a compact Kubernetes ValidatingAdmissionPolicy example that blocks deployments if the image isn’t from our registry and forces an owner label. It’s not perfect, but it catches a surprising number of “oops” moments before they reach prod:

apiVersion: admissionregistration.k8s.io/v1
kind: ValidatingAdmissionPolicy
metadata:
  name: require-trusted-ai-deploys
spec:
  matchConstraints:
    resourceRules:
      - apiGroups: ["apps"]
        apiVersions: ["v1"]
        operations: ["CREATE","UPDATE"]
        resources: ["deployments"]
  validations:
    - expression: "object.spec.template.metadata.labels.exists('ai.oasis/owner')"
      message: "Missing label ai.oasis/owner"
    - expression: "object.spec.template.spec.containers.all(c, c.image.startsWith('registry.internal/oasis/'))"
      message: "Images must come from registry.internal/oasis/"

On the risk side, we adopt lightweight checks from the NIST AI Risk Management Framework. We borrow what maps cleanly to operations: define harmful failure modes, plan mitigations, and make a mental checklist that any engineer can run in a pinch. “Does it handle malformed inputs? Can we rate-limit or pause it? Do we log enough context to debug without storing secrets?” And yes, we keep an obvious kill switch—either a feature flag or a routing rule—that we can flip in under a minute. The best incident mitigation is a big, friendly “off” button that’s tested in daylight.

Ship ai Like Software: CI/CD That Knows Models

Shipping ai reliably looks a lot like shipping normal software, plus two twists: model artifacts and evaluation gates. We add those to the pipeline, make them visible, and keep the whole thing boring. A green check should mean the deploy is safe to roll, not “we ran flakey notebooks and prayed.” We treat the model as a package: pinned dependencies, reproducible build, and a provenance trail. Your future self will thank you when a product manager asks, “What changed last Tuesday?”

Here’s a compact GitHub Actions workflow that runs unit tests on prompt tooling, builds an image, runs a smoke evaluation, and pushes on success:

name: build-and-ship-ai
on: [push]
jobs:
  build:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - uses: actions/setup-python@v5
        with: { python-version: '3.11' }
      - run: pip install -r requirements.txt
      - run: pytest -q tests/unit
      - run: python eval/smoke_eval.py --model local --min_score 0.85
      - run: docker build -t registry.internal/oasis/assist:${{ github.sha }} .
      - run: docker push registry.internal/oasis/assist:${{ github.sha }}

For serious model versioning and lineage, we like MLflow’s model registry because it behaves like a source of truth for artifacts and evaluations. We tag each release candidate with evaluation metrics and a link to the data snapshot used in tests. If a canary underperforms, rollbacks are trivial: pin the prior model version and redeploy the same container. We prefer progressive delivery (tiny traffic slice, watch metrics, widen) over big-bang rollouts; repetition beats bravado. And we keep the evaluation step as code in the repo, not a mystical spreadsheet on someone’s desktop.

Observe Outcomes, Not Vibes

Observability for ai has to measure what the business and the user feel, not just CPU and 99th percentile latency. We still track the usual suspects—latency, error rates, saturation—but we add task-specific quality signals: success labels from human feedback, drift signals from input distributions, and guardrail triggers like toxic content flags or PII detections. A tidy dashboard that shows these side by side helps us catch “it’s fast but wrong” before users do. If the model is text-heavy, we sample outputs to a moderation pipeline and store redacted exemplars with a short TTL; we want enough visibility to debug without hoarding sensitive content.

We define SLOs that reflect user impact: median time-to-usable-output, percent of suggestions accepted by humans, or percent of tickets closed without escalation. That maps nicely to the reliability language ops already speaks, and it keeps our reviews concrete. If we can’t turn an intuition into an SLO, we question whether it’s a real requirement. The Google SRE guidance on SLOs is still the cleanest mental model for this: choose a few signals that directly represent reliability for the user, and tolerate error budgets where it makes business sense. For ai, we also experiment with “quality budgets”—a formal allowance for lower accuracy during controlled canaries or after retraining—so we can move fast without pretending the system is perfect. When the budget is gone, we slow down. No drama, just math.

Cost Controls That Actually Trigger

Costs creep up in two places: GPU time and tokens. We set ceilings for both and enforce them with tooling, not discipline alone. For GPU, we keep small, efficient models handy for the 80% case and reserve the heavy hitters for the 20% that need them. Autoscaling is great until it silently provisions expensive nodes. We cap hard resources in namespaces so that “just one more replica” doesn’t spin up surprise costs. Here’s a simple Kubernetes ResourceQuota that limits GPU requests and total pods for an ai namespace:

apiVersion: v1
kind: ResourceQuota
metadata:
  name: ai-cost-guardrails
  namespace: ai-services
spec:
  hard:
    requests.nvidia.com/gpu: "8"
    limits.nvidia.com/gpu: "8"
    pods: "50"

We also track cost-per-request as a first-class metric. If we use external LLMs, every prompt is a small invoice, so we cache aggressively and normalize prompts to avoid duplication. We roll up token usage by service and team, publish it weekly, and celebrate the teams that shave pennies without hurting quality. Visibility is a shockingly strong motivator. We’ve found Kubernetes quota docs useful when tuning limits and requests—especially the gotchas around aggregate metrics in mixed workloads; the official ResourceQuota guide is short and worth a bookmark.

Finally, we protect ourselves from “cascading novelty”: when someone finds a creative new use for a model that makes product sense, our budgets prevent a surprise bill. That’s not stinginess; it’s space to scale intentionally, with a plan for the next tier of spend.

Team Rituals That Keep Us Out Of Trouble

We keep two rituals light and relentless: pre-merge reviews that include a safety glance, and post-incident reviews that produce one concrete improvement each. During review, we ask the same few questions: will this handle malformed input without stepping on a rake? Are logs free of secrets? Is there a soft fail path if the model is down or slow? Has the output been sampled by a human? If we can’t answer confidently, we add a test or a guardrail and move on. It’s not bureaucracy; it’s consistent house rules that keep our future selves from playing detective.

On incidents, we write the shortest report that explains user impact, root cause, and one clear prevention step. Then we actually do that step. It might be adding a drift alarm, lowering a rate limit, or making the kill switch more obvious. We celebrate such fixes because they level up the whole system, not just the hero of the week. We also keep a short privacy checklist that ships with every feature: redaction verified, retention sane, access minimal, and owner named. You don’t need a thousand policies; you need five that everyone remembers.

Finally, we practice empathy for the users and ourselves. ai can feel like magic until it acts like a raccoon in the attic. When it does, we fall back on our habits: small scope, clear metrics, staged rollouts, honest dashboards, and an easy off-ramp. It’s not glamorous, but it is repeatable. And repeatable is how we ship safely, week after week.
