Quick Definition

Artificial intelligence (AI) is the science and engineering of creating systems that perform tasks which normally require human intelligence, using data, models, and automation.
Analogy: AI is like a recipe-following robot chef that learns new recipes from examples, adapts when ingredients change, and warns you when the oven is too hot.
Formal technical line: AI is a broad set of algorithms and system designs that map inputs to outputs via learned or encoded models, often optimized under constraints like latency, cost, and robustness.

What is artificial intelligence?

What it is / what it is NOT

• AI is a set of methods — statistical models, neural networks, symbolic reasoning, and hybrid systems — used to automate decision-making and pattern recognition.
• AI is NOT magic; it is constrained by data quality, compute, and explicit objectives.
• AI is NOT equivalent to “autonomy.” Autonomy includes operational control, safety cases, and governance beyond model outputs.

Key properties and constraints

• Data dependence: performance scales with data quantity and quality.
• Objective alignment: models optimize explicit loss functions which may not capture human values.
• Resource constraints: latency, compute, memory, and cost shape feasible architectures.
• Uncertainty: probabilistic outputs and distributional shifts require defensive design.
• Observability: without telemetry, model behavior in production is opaque.

Where it fits in modern cloud/SRE workflows

• AI systems are deployed alongside microservices and data platforms; they must integrate with CI/CD, observability, and security controls.
• SRE responsibilities include defining SLIs for model quality, tracking drift, managing resource scaling for inference, and handling incidents where models cause harm or outages.
• Cloud-native patterns (Kubernetes, serverless, managed ML platforms) are common deployment targets but require careful orchestration of data pipelines and model lifecycle automation.

A text-only “diagram description” readers can visualize

• Imagine a layered pipeline: Data sources feed an ingestion layer; processed data goes to feature stores and training pipelines; models are built, validated, and pushed to a model registry; deployment uses inference services behind APIs; telemetry flows from inference and downstream systems back to monitoring and retraining triggers.

artificial intelligence in one sentence

Artificial intelligence is the practice of training and operating computational models to perform tasks that require perception, reasoning, or prediction, integrated into systems with monitoring and governance.

Why does artificial intelligence matter?

Business impact (revenue, trust, risk)

• Revenue: AI drives personalization, automation, and predictive capabilities that directly increase conversion, retention, and operational throughput.
• Trust: Poorly designed models degrade customer trust; explainability and guardrails are business-critical.
• Risk: AI introduces regulatory, privacy, and safety risk requiring governance, audits, and incident remediation processes.

Engineering impact (incident reduction, velocity)

• Incident reduction: Predictive maintenance and anomaly detection reduce outages when integrated with ops.
• Velocity: Automated data labeling, model training pipelines, and feature stores speed feature delivery.
• Trade-offs: Increased velocity can create new classes of incidents if observability and testing lag.

SRE framing (SLIs/SLOs/error budgets/toil/on-call)

• SLIs: model latency, prediction accuracy, data freshness, and inference error rates.
• SLOs: acceptable ranges for those SLIs; e.g., 99th percentile latency under threshold and accuracy above baseline.
• Error budgets: allow controlled experimentation with model variants.
• Toil: data labeling and manual checks are significant toil areas; automation reduces recurring manual work.
• On-call: incidents include model regression, data pipeline failure, and model-induced downstream faults.

3–5 realistic “what breaks in production” examples

1. Data schema change breaks feature extraction, causing degraded model accuracy without obvious service errors.
2. Model serving nodes run out of GPU memory under traffic spike, leading to increased latency and timeouts.
3. External policy change causes model outputs to become non-compliant, requiring rollback and audit.
4. Training pipeline consumes stale labels due to a lagging ground truth source, causing silent drift.
5. Adversarial input pattern or scraping causes unexpected outputs affecting reputation.

When should you use artificial intelligence?

When it’s necessary

• When the task requires pattern detection on large, noisy datasets that rule-based logic cannot capture.
• When personalization, forecasting, or complex prediction directly impacts revenue or safety and simple heuristics fail.

When it’s optional

• When deterministic rules suffice and are cheaper to develop and audit.
• When dataset size is small and human-in-the-loop or rules are faster and safer.

When NOT to use / overuse it

• Don’t use AI to mask poor product design or as a substitute for clear business logic.
• Avoid using AI where interpretability is legally required and models cannot be explained.
• Don’t apply AI for low-value features where maintenance cost outweighs benefits.

Decision checklist

• If X: dataset > tens of thousands of labeled examples AND Y: performance gains uncertified by rules -> build ML model.
• If A: strict regulatory explainability required AND B: model is a black box -> consider rules or transparent models.

Maturity ladder: Beginner -> Intermediate -> Advanced

• Beginner: Prototypes, small datasets, offline evaluation, batch inference.
• Intermediate: CI/CD for models, model registry, feature store, online inference and monitoring.
• Advanced: Continuous training loops, causal evaluation, safe deployment (canary/rollout), governance and policy enforcement.

How does artificial intelligence work?

Components and workflow

1. Data ingestion: collect raw data from sources and annotate if necessary.
2. Data processing: clean, normalize, and transform data into features.
3. Feature storage: store features in a feature store for training and serving parity.
4. Model training: train model on processed features; run validation and fairness checks.
5. Model registry: version and store artifacts with metadata.
6. Deployment: serve models via inference infrastructure with autoscaling and redundancy.
7. Monitoring: collect telemetry for model quality, drift, and system health.
8. Retraining and governance: execute retraining or rollback when signals indicate degradation.

Data flow and lifecycle

• Raw data -> ETL/ELT -> Features -> Training -> Model artifacts -> Deployment -> Inference -> Observability -> Feedback for retraining.

Edge cases and failure modes

• Data drift: distribution changes over time.
• Label leakage: training uses future information unintentionally.
• Cold start: insufficient user data for personalization.
• Resource exhaustion: inference nodes overloaded.
• Adversarial inputs: intentional or accidental out-of-distribution inputs.

Typical architecture patterns for artificial intelligence

1. Batch training, batch inference: for non-real-time analytics and periodic scoring.
2. Online inference with offline training: low-latency APIs using precomputed features.
3. Streaming training and inference: continuous learning from event streams for real-time updates.
4. Edge inference with cloud training: train centrally, deploy lightweight models to devices.
5. Hybrid human-in-the-loop: model proposes outputs and humans validate for high-risk decisions.
6. Multi-model ensemble serving: combine specialists to improve accuracy and robustness.

Best Practices & Operating Model

Ownership and on-call

• Assign clear ownership: model owner, data owner, and infra owner.
• On-call responsibilities include responding to SLO breaches and model incidents.
• Use runbooks for common incidents and ensure accessible documentation.

Runbooks vs playbooks

• Runbook: step-by-step operational procedures for known incidents.
• Playbook: higher-level decision frameworks for complex scenarios requiring judgment.

Safe deployments (canary/rollback)

• Use canary deployments with automatic comparison of key SLIs.
• Automate rollback on canary failure and require manual approvals for risky rollouts.

Toil reduction and automation

• Automate repetitive tasks: data labeling pipelines, retraining, and model evaluation.
• Use human-in-the-loop for high-risk decisions where automation is immature.

Security basics

• Secure model artifacts and registries.
• Encrypt data at rest and in transit.
• Apply access controls for feature stores and training data.
• Sanitize inputs and implement adversarial testing.

Weekly/monthly routines

• Weekly: Review SLO burn rate, recent alerts, and quick model health check.
• Monthly: Evaluate drift metrics, retrain schedule, and cost review.
• Quarterly: Bias and compliance audit, and architecture review.

What to review in postmortems related to artificial intelligence

• Root cause: data, model, infra, or process.
• Detection latency: when and how it was detected.
• Impact: business metric delta.
• Mitigation: steps taken and time to rollback.
• Preventative actions: data validation, monitoring, and release gating.

Frequently Asked Questions (FAQs)

What is the difference between AI and machine learning?

Machine learning is a subset of AI focused on algorithms that learn from data; AI includes ML plus symbolic systems and planning.

How do I know if my problem needs AI?

If rules fail at scale, or patterns exist only in large datasets and impact key business metrics, AI may be justified.

How do you measure AI performance in production?

Use SLIs like accuracy, latency, drift rate, and business KPIs; pair with SLOs and alerting.

What is model drift and how do you detect it?

Drift is distribution change in inputs or outputs; detect via statistical distance metrics, feature monitors, and performance degradation.

How often should models be retrained?

Varies; retrain on drift signals or scheduled intervals based on label latency and use-case criticality.

How do I deploy models safely?

Use canary rollouts, shadow testing, golden inputs, and automated rollback on SLI degradation.

What are key security concerns with AI?

Data leakage, model inversion, unauthorized model access, and adversarial inputs; mitigate with encryption and hardening.

Can AI replace data engineers?

No; AI augments workflows. Data engineers are essential for pipeline reliability and feature parity.

How should I set SLOs for an ML model?

Align SLOs with business outcomes; set SLOs for latency and model quality metrics using historical baselines.

What is human-in-the-loop and when to use it?

A design where humans review model outputs for safety or training; use for high-risk or low-confidence predictions.

Are pre-trained models safe to use?

Pre-trained models are powerful but carry upstream data biases; evaluate and fine-tune for the target domain.

How much compute do models require?

Varies widely by model size, training dataset, and inference latency requirements; estimate via profiling.

How to manage model explainability?

Use local and global explanation tools, maintain documentation, and include explainability in CI checks.

What telemetry is most important for models?

Prediction quality, latency, input distributions, feature freshness, and resource utilization are key.

How to avoid bias in AI?

Audit datasets, include fairness metrics, and design mitigation strategies like reweighting or targeted data collection.

How to reduce inference cost?

Optimize models (quantization, pruning), use right-sizing, caching, and smart routing (batching).

Is it better to use serverless or Kubernetes for inference?

Depends: serverless excels for sporadic traffic, K8s for predictable, high-throughput workloads.

How to perform postmortems for AI incidents?

Document detection, root cause, impact on metrics, mitigation, and preventative actions; include data flow diagrams.
