AI Pipeline Architecture: Development & Production Pipelines for AI Systems

AI pipeline architecture defines how data flows through AI systems — from raw ingestion through model training and serving to production monitoring. This skill produces comprehensive pipeline architecture documentation covering development pipelines (experimentation to model artifact), production pipelines (data ingestion to prediction delivery), data store selection, model registry design, CI/CD strategy, and measurable requirements. [EXPLICIT]

Principio Rector

El pipeline es la arquitectura. El modelo es solo un componente dentro de él. La mayoría del esfuerzo en sistemas de IA de producción está en la infraestructura de datos, no en el algoritmo. Un pipeline mal diseñado convierte un buen modelo en un sistema frágil. Un pipeline bien diseñado permite que modelos mediocres evolucionen.

Filosofía de Pipeline Architecture

1. Dos pipelines, un registro. Development pipeline y production pipeline son sistemas distintos con requisitos distintos (experimentación vs. confiabilidad). El model registry es el puente que los conecta. Sin registro, no hay reproducibilidad. [EXPLICIT]
2. Data quality es el primer gate, no el último test. En pipelines de IA, basura entra, basura sale — con la agravante de que el modelo amplifica los sesgos de datos malos. Quality gates al inicio del pipeline, no al final. [EXPLICIT]
3. Blue y Gold, no YOLO deploy. Desplegar un modelo nuevo directamente a producción es irresponsable. La estrategia Blue (producción) y Gold (staging con validación) garantiza que ningún modelo llega a usuarios sin pasar gates automatizados. [EXPLICIT]

Delivery Structure: 6 Sections

S1: Development Pipeline Architecture

Maps the experimentation-to-artifact pipeline where models are built, trained, and validated. [EXPLICIT]

Stages:

• Data Quality Checks: Schema validation, anomaly detection, distribution analysis, business rule verification
• Data Transforms: Feature engineering, normalization, encoding, embedding generation
• Data Summary: Statistical profiling, correlation analysis, class balance assessment
• Model Building: Algorithm selection, architecture definition, initial training
• Model Tuning: Hyperparameter optimization, cross-validation, regularization
• Model Verification: Holdout evaluation, fairness testing, robustness assessment, explainability scoring
• Code Commit: Model artifacts + code + configs registered in model registry with full lineage
• CI/CD Dev Ops: Automated pipeline testing, artifact validation, security scanning

Key decisions:

• Experiment tracking tool (MLflow, W&B, Neptune, SageMaker Experiments)
• Training orchestration (Kubeflow Pipelines, Vertex AI, SageMaker Pipelines, Airflow)
• Reproducibility strategy (data versioning, environment pinning, seed management)

S2: Production Pipeline Architecture

Maps the data-to-prediction pipeline that serves AI capabilities in production. [EXPLICIT]

Stages:

• Data Cleansing: Automated validation, anomaly detection, quality enforcement with feedback loops
• Data Transformation: Feature computation via feature store, embedding generation, format conversion
• Model Execution: Prediction generation with model registry integration, A/B testing, monitoring hooks
• Results Store: Prediction storage, feature attribution, explanation logging, BI integration
• Pipeline Operations: Monitoring, alerting, self-healing, visualization, configurable logging

Key decisions:

• Batch vs. streaming vs. hybrid pipeline topology
• Feature store adoption (Feast, Tecton, Vertex AI Feature Store, or custom) → evolving toward Feature Platform (compute + store + monitoring + governance as integrated platform)
• Model serving framework (TF Serving, TorchServe, Triton, vLLM, SageMaker Endpoints)
• Monitoring granularity (sample rate, logging level, retention policy)
• Streaming pipeline pattern (Kappa for pure streaming, Lambda for batch+streaming hybrid)

S3: Data Store Technology Selection

Selects appropriate storage technologies for each pipeline component. [EXPLICIT]

Store types and AI use cases:

• Relational (PostgreSQL, MySQL): Metadata, experiment tracking, model registry, audit trails
• Object (S3, GCS): Training data, model artifacts, archives
• Key-Value (Redis, DynamoDB): Feature serving cache, prediction cache, real-time lookup
• Graph (Neo4j): Knowledge graphs, entity relationships, fraud networks
• Vector (Pinecone, Qdrant, pgvector): Embedding storage, semantic search, RAG retrieval

Selection criteria: Query complexity, latency requirements, scale, consistency model, cost, AI-native capability.

Multi-store pattern: Most production AI systems combine 3-4 store types with synchronization and lineage tracking across boundaries.

S4: Model Registry & Versioning

Designs the bridge between development and production pipelines. [EXPLICIT]

Registry capabilities:

• Model artifact storage with version history
• Metadata: training metrics, data hash, hyperparameters, lineage
• Stage management: Staging → Canary → Production → Archived
• Access control and approval workflows
• A/B experiment configuration
• Rollback support with instant reversion

Key decisions:

• Registry tool (MLflow, SageMaker Model Registry, Vertex AI, W&B)
• Versioning strategy (semantic versioning, timestamp-based, hash-based)
• Promotion workflow (automated gates vs. manual approval vs. hybrid)
• Multi-model coordination (dependent models, ensemble management)

S5: CI/CD for AI (Blue & Gold)

Designs the deployment strategy connecting development artifacts to production serving. [EXPLICIT]

Blue Pipeline (Production): Currently serving, fully validated, rollback target. Gold Pipeline (Staging): New version under validation, receives shadow/canary traffic.

Validation gates:

1. Model validation: accuracy, AUC, fairness, robustness meet thresholds
2. Feature validation: distributions match expected profiles
3. Data quality: input data passes schema and quality checks
4. Performance: latency and throughput within SLA
5. Security: no new vulnerabilities, access controls intact
6. Regression: no degradation vs. current Blue performance

Promotion flow: Gold passes all gates → canary traffic → gradual shift → full promotion → Gold becomes Blue → previous Blue archived.

Key decisions:

• Canary percentage and duration
• Automated vs. manual gate approval
• Rollback trigger criteria
• Pipeline-level vs. model-level deployment

S6: Requirements Framework (AP/NF/SEC/CP)

Defines measurable requirements across four categories with thresholds and objectives. [EXPLICIT]

Performance (AP-1 to AP-13): Data processing speed, model accuracy, fairness, explainability, robustness.

Non-Functional (NF-1 to NF-9): Availability (>99.9%), recovery time (<1 min), fault detection (<0.5 secs), drift detection (<1 hour), pipeline isolation.

Security (SEC-1 to SEC-6): PKI for external interfaces, audit logging, adversarial protection, data access controls, model extraction monitoring.

Compliance (CP-1 to CP-7): Authorized data access, transaction archival, encryption at rest/in use, audit trails, model governance workflows.

Assumptions

• Team has or will build experience with ML pipeline orchestration
• Infrastructure supports the compute requirements for training and inference
• Data sources are identified and access is available or negotiable
• Model registry and CI/CD are organizational priorities (not afterthoughts)
• Monitoring and observability budget is allocated

Limits

• Focuses on pipeline architecture, not infrastructure provisioning (see metodologia-infrastructure-architecture)
• Does not design internal module structure (see metodologia-ai-software-architecture)
• Does not select design patterns or tactics (see metodologia-ai-design-patterns)
• Does not define testing strategy beyond pipeline gates (see metodologia-ai-testing-strategy)
• GenAI-specific pipelines (RAG indexing, agent orchestration) require metodologia-genai-architecture
• AWS-specific pipeline services (SageMaker Pipelines, Step Functions, Bedrock) covered by metodologia-aws-architecture-design

Edge Cases

Notebook-to-Production Migration: Data scientists work in Jupyter notebooks; production requires orchestrated pipelines. Bridge with notebook-aware orchestrators (Papermill, Ploomber). Prioritize extracting feature engineering and model training into reusable pipeline stages. [EXPLICIT]

Multi-Team Pipeline Ownership: Different teams own different pipeline stages (data eng owns ingestion, ML eng owns training, platform owns serving). Clear data contracts between stages are essential. Feature store becomes the coordination point. [EXPLICIT]

Real-Time + Batch Hybrid: System needs both real-time predictions (online serving) and batch analytics (offline scoring). Lambda or Kappa architecture patterns. Feature store must support both online (low-latency) and offline (batch) serving. [EXPLICIT]

Regulated Pipeline (Finance, Healthcare): Every pipeline stage must produce audit-worthy artifacts. Data lineage tracking from source to prediction. Model governance gates require human approval before production promotion. [EXPLICIT]

Manejo de Inputs Ambiguos

• Si el nombre del sistema no se proporciona: solicitar antes de proceder.
• Si el MODO no se especifica: usar piloto-auto (default).
• Si el contexto es insuficiente para una sección: documentar como "[Requiere input adicional: {descripción}]" en lugar de inventar contenido.
• Si no hay pipeline existente: diseñar desde greenfield con la fase 0 (foundation) como prioridad.
• Si el equipo no tiene experiencia con orquestadores: recomendar el más simple viable (Dagster para Python-first, Airflow para ecosistema amplio).

Validation Gate

Before finalizing delivery, verify:

• Development and production pipelines are designed as separate systems connected by model registry
• Each pipeline stage has defined inputs, outputs, and quality gates
• Data store selection justified by workload characteristics (not technology preference)
• Model registry design includes versioning, lineage, staging, and rollback
• CI/CD strategy uses Blue & Gold (or equivalent staged deployment)
• Validation gates cover model quality, data quality, performance, security, and regression
• Requirements framework includes all four categories (AP, NF, SEC, CP) with thresholds
• Training-serving skew risk explicitly addressed in pipeline design
• Monitoring strategy covers all pipeline stages (not just model serving)
• Pipeline architecture is deployable (not just theoretical)
