Featured answer: What is the data infrastructure for AI?

Data infrastructure for AI is the scalable foundation of data, compute, and tooling that ingests, stores, processes, governs, and serves data to ML/LLM apps.

1. Ingestion: Collect batch/stream data with schema control and replay.
2. Storage/Lakehouse: Durable, columnar storage with ACID (e.g., Delta/Iceberg).
3. Feature Store/Vector DB: Reusable features and embeddings with online/offline parity.
4. Compute: Elastic CPU/GPU/TPU for training/inference.
5. Orchestration: CI/CD, pipelines, and scheduling for data and models.
6. Governance & Security: Catalog, lineage, PII controls, keys, policies.
7. Monitoring & Observability: Data quality, drift, latency, cost.
8. Integration: APIs, event buses, and connectors to business apps.

Example cloud‑native stack: Kafka → Delta Lake → Feast + vector DB → Ray/Vertex → Argo → Prometheus/Grafana. One‑page diagram and templates: Data platform modernization.

Why this matters: Business outcomes driven by proper AI data infrastructure

A sound AI data infrastructure shortens iteration cycles by 30–60%, cuts p95 inference latency by 40–70%, and reduces pipeline failure rates below 1% change‑fail. McKinsey's State of AI notes that operational excellence correlates with higher ROI from AI programs (McKinsey). Algorithmia's enterprise surveys observed that deployment bottlenecks, not modeling, stall value realization (Algorithmia report).

Three quick ROI scenarios you can benchmark:

• Customer service automation: 25–40% deflection, 15% AHT reduction; payback in 3–5 months.
• Predictive maintenance: 20–30% downtime reduction; 10–15x fewer emergency callouts.
• Fraud detection: +5–10% precision at same recall; chargebacks down 20%.

What kind of infrastructure is needed for AI?

Prototype vs. production: Prototypes prioritize speed—managed notebooks, small GPUs, minimal ops. Production emphasizes reproducibility, lineage, SLOs, and cost controls.

Real‑time vs. batch: Real‑time requires low‑latency networking (25–100 Gbps), vector indexes, autoscaling, and cache. Batch emphasizes high throughput (2–5 GB/s), spot/queue execution, and checkpointing.

On‑prem vs. cloud vs. hybrid: On‑prem secures data locality and predictable cost; cloud wins on elasticity; hybrid suits data‑gravity with cloud burst for training.

Recommended specs (typical):

• Training: 8×A100/H100 80GB or GKE/AKS with NCCL; ≥25 Gbps east‑west, 50k+ IOPS NVMe scratch.
• Real‑time LLM: 1–2×L4/A10G per 150–250 RPS (context ≤2k), Redis/pgvector cache, p95 <150 ms budget to model.
• Storage: Lakehouse on S3/GCS/ADLS with Delta/Iceberg; 10–30 TB starting; ≥500 MB/s read per node.

Minimum viable stack for pilot projects

Use credits and managed services: cloud notebooks, a small GPU (L4/A10G), managed Kafka/PubSub, Delta/Iceberg on object store, Feast for features, and a hosted vector DB. Timeline: Week 1–2 ingest + schema; Week 3–4 first model; Week 5–6 gated pilot with observability. Start with MLOps consulting to accelerate.

How AI infrastructure differs from traditional IT infrastructure

Dimension	AI infrastructure	Traditional IT infrastructure
Workload pattern	Data/compute bursts, GPU intensive	Steady, CPU-centric
Data pipelines	Feature/embedding stores, streaming	ETL to warehouse
Observability	Data quality, drift, token/cost	Uptime, CPU/RAM
Release cadence	Model/feature versioning via CI/CD	App releases
SLAs/SLOs	Latency budgets, freshness, accuracy	Availability
Procurement	GPU capacity, spot markets	Reserved CPU/storage

Reference architecture patterns and reusable templates

1. Real‑time stream inference: Kafka → Stream processor (Flink) → Feature/Vector → Model service on GPUs → API Gateway. Use managed Kafka, serverless Flink, and GPU autoscaling. Reference IaC: LLM observability.

2. Batched retraining: Object store → Delta/Iceberg → Spark/Ray → Model registry → CI/CD deploy. Use managed Spark and a registry (MLflow/Vertex Model Registry).

3. Hybrid secure on‑prem inference: On‑prem vector + GPU serving, cloud training bursts via private link; policy synced by OPA.

Costing, sizing and TCO models (How to budget)

Assumptions: GPU $2.10–$3.40/hr (L4/A10G), storage $0.023/GB‑mo, egress $0.05/GB, vector DB $0.20 per million queries, orchestration $0.10 per pipeline hour. Example monthly TCO below aggregates compute, storage, and platform overhead at 15%.

Sensitivity: GPU hours dominate. Doubling context length can 1.6–1.8x inference cost; adding a Redis cache often cuts it by 25–40%. Download the spreadsheet model and tweak GPU hours and data volume: Data platform modernization.

Data governance, lineage and security for production AI

Checklist: catalog every dataset; enable column‑level lineage; automated PII discovery; consent and retention policies; model provenance with artifact hashes; KMS‑backed secrets; least‑privilege IAM. Map to SOC 2, GDPR, and HIPAA where relevant. Incident runbook: detect (alerts on drift/PII leaks), contain (disable route), eradicate (rollback model), recover (retrain), and post‑mortem within 48 hours. See the AWS ML Lens for patterns (AWS ML Lens).

Operational playbook: MLOps, monitoring and SRE for AI automation

Metrics: data freshness, schema violations, p50/p95 latency, throughput, token rate, error rate, drift (PSI/KL). Triggers: PSI>0.2 for 3 days → retrain; accuracy drop >3 pts → rollback. CI/CD: unit tests, data contracts, canary by traffic shard, shadow deploys. Prometheus examples: request_latency_seconds_bucket{service="llm"}; data_freshness_seconds{table="features"}. Log query: filter status!=200 and latency>0.5s.

Who builds AI infrastructure and vendor selection criteria

Built by cross‑functional teams (Data/ML/DevOps/SRE/Security) or with specialized partners. Vendor checklist: GPU roadmap, IaC support, data governance, lineage, model registry, observability, SLOs, cost controls, support SLAs, exit strategy. RFP sample: request reproducible Terraform, latency/cost benchmarks, and compliance mappings.

Common pitfalls and how to avoid them

Top failures: poor data quality, missing lineage, undersized network, no cache, unbounded context, weak CI/CD, no rollback plan, and cost blind spots. Mitigate with contracts, lineage tools, 25–100 Gbps networking, caching, guardrails on tokens, staged deployments, and per‑team cost budgets.
