From Data Silos to Reliable AI Inputs: An Infrastructure Roadmap

From Data Silos to Reliable AI Inputs: An Infrastructure Roadmap

Hook: If your AI models are inconsistent, slow to deploy, or produce low-trust outputs, the root cause is rarely the model alone — it's the data infrastructure driving those models. Salesforce’s 2025–26 findings show that weak data management and persistent silos are the single largest barrier to scaling AI in the enterprise. This article gives a pragmatic, infrastructure-centric roadmap — cataloging, pipelines, lineage, and hosting patterns — engineered for performance, observability, and cost predictability.

Executive summary — most important first

Enterprises that want AI readiness and trustworthy data must treat data infrastructure as product infrastructure. Start by building a metadata-first foundation: a centralized catalog and schema registry, metadata-driven data pipelines, automated data lineage capture, and hosting patterns that align with latency and cost SLAs. Couple that with end-to-end observability and cost KPIs. The result: predictable performance, fewer model regressions, and measurable ROI from AI investments.

Why this matters now (2026 context)

Late 2025 and early 2026 accelerated three dynamics:

• Proliferation of production LLMs and retrieval-augmented workflows that amplify upstream data issues.
• Regulatory pressure — privacy and provenance requirements now demand auditable data lineage for models in finance, healthcare, and regulated industries.
• Cloud cost sensitivity after a multi-year cycle of overprovisioned infrastructure; IT teams need predictable, optimized spend for data pipelines and inference hosting.

Salesforce’s diagnosis — what we can learn

Salesforce’s State of Data and Analytics (2025–26) highlights persistent silos, inconsistent governance, and low data trust as prime inhibitors to enterprise AI scale. Their research surfaces three practical failures:

• Incomplete metadata and missing catalog coverage across teams.
• Opaque ETL/ELT pipelines with no automated lineage or provenance.
• Mismatch between hosting architecture and production latency/cost constraints.

Those failures map directly to infrastructure choices — catalog, pipelines, lineage capture, and hosting patterns — which is why an infrastructure-first strategy gives the highest leverage.

Roadmap overview — four infrastructure pillars

To move from silos to reliable AI inputs, organize work into four pillars. Each pillar includes concrete implementation steps and observability/cost controls.

1. Cataloging & metadata
2. Data pipelines & ETL/ELT
3. Lineage, observability & testing
4. Hosting patterns & cost/performance ops

1. Cataloging & metadata — make data discoverable and actionable

Why: A catalog is the control plane for governance, discoverability, and AI readiness. Without it, teams duplicate work and models consume untrusted inputs.

Core components

• Entity model: datasets, tables, features, pipelines, models, and owners.
• Schema registry: canonical schemas, versioning, and compatibility rules.
• Policies: access controls, retention, sensitivity labels, and PII tags.
• Search & lineage links: dataset-to-pipeline, dataset-to-feature, dataset-to-model.

Implementation steps (practical)

1. Inventory critical datasets (top 20 by usage/impact) in 2 weeks and onboard into a catalog (Amundsen, DataHub, or a managed equivalent).
2. Publish a schema registry for producer teams and enforce compatibility checks in CI pipelines.
3. Tag datasets with business-critical metadata: owner, SLA, freshness requirement, sensitivity, and intended AI use.
4. Integrate the catalog with CI/CD and model registries so ML engineers can find validated features and training data.

Observability & cost controls

• Track catalog coverage (% of critical datasets registered).
• Monitor schema change events per week and failures caught by registry checks.
• Chargeback: include catalog metadata in cost allocation so teams pay for storage/computation tied to datasets.

2. Data pipelines & ETL/ELT — move from ad‑hoc jobs to metadata-driven flows

Why: Pipelines are where reliable inputs are produced. Infrastructure choices determine latency, cost, and the ability to enforce quality gates.

Design principles

• Metadata-driven pipelines: pipelines declare inputs/outputs, contracts, and SLAs in machine-readable metadata.
• Idempotency and immutability: datasets should be append-only or snapshot-based to preserve provenance.
• Push vs. pull: choose push for event-driven flows and pull for scheduled ELT to reduce coupling and cost spikes.
• Feature engineering separation: separate feature stores for serving vs. training to control freshness and compute costs.

Practical pipeline patterns

• Batch ELT with lazy materialization: store raw events in a cheap object store (S3/GCS), transform into curated tables on schedule, and materialize only high-demand tables.
• Streaming micro-batches: use Kafka or cloud equivalents (Pub/Sub, Event Hubs) with stream processing (Flink, Spark Structured Streaming) when low-latency features are required; design these flows with principles from live-streaming stacks for low-latency edge authorization and throughput.
• Hybrid feature store: use a low-cost object-store-backed feature repo for training + a low-latency serving layer (Redis/Vector DBs) for inference.

Actionable steps

1. Define and enforce data contracts for producers (schema, cadence, freshness) and add them to the catalog.
2. Pipeline CI: implement unit and integration tests for transformations, execute on PRs, and gate merges on test success. For guidance on tradeoffs between serverless and dedicated orchestration, see serverless vs dedicated crawlers.
3. Adopt incremental/CDC patterns to limit recompute costs and keep data fresh for models.

3. Data lineage, observability & testing — trust through verification

Why: Lineage and observability turn mysterious regressions into actionable alerts. They’re the infrastructure that enforces trust and auditability.

Lineage capture

Capture lineage at two levels:

• Logical lineage: which datasets and transformations produced a table or feature.
• Physical lineage: which jobs, timestamps, and file objects back each materialization (important for audits).

Standards & tools

Adopt open standards such as OpenLineage and tools like Marquez to capture job-to-dataset edges. Combine with Great Expectations or Soda for data quality assertions and Monte Carlo or custom dashboards for SLA monitoring.

Observability matrix

• Freshness: lag between expected and actual data arrival (SLA).
• Completeness: percent of expected rows or partitions present.
• Accuracy: schema conformance and constraint checks.
• Drift: statistical differences vs. baseline distributions for features.

Testing & prevention

1. Implement contract tests in CI: schema and nullability checks, cardinality guards.
2. Data regression tests post-deploy: compare key metrics to prior baseline and block model retraining if thresholds exceeded.
3. Lineage-based impact analysis: when a producer schema changes, automatically compute impacted models/dashboards and notify owners.

“If you can’t trace a prediction back to its inputs and validate those inputs, you don’t have an auditable AI workflow.”

4. Hosting patterns — match latency and cost SLAs

Why: The hosting pattern you choose for storage, feature serving, and inference determines both performance and cost predictability. Mismatches are a major driver of runaway bills and unreliable behavior.

Storage and compute tiers

• Cold archival: object stores (S3, GCS) with lifecycle policies; ideal for raw data and training archives.
• Warm/curated: lakehouse tables (Delta, Iceberg) for analytical workloads and batch training; enable time-travel.
• Hot/serving: low-latency databases, vector stores, or Redis for inference-serving features.

Inference hosting patterns

• Batch inference: schedule large runs on spot instances to reduce cost; materialize predictions into tables.
• Real-time inference: use autoscaling serverless endpoints (Knative, cloud functions) with dedicated caching for hot features and rate-limiting to control spend. Evaluate the serverless tradeoffs described in serverless vs dedicated analysis.
• Hybrid: precompute popular model outputs during off-peak hours and serve them from a fast cache; fall back to real-time for cold paths.

Multi-region & edge considerations

For global applications, place read replicas and caches at edge points. Use single-region authoritative writes with asynchronous replication for cost predictability. Ensure lineage metadata includes region and timestamp to support cross-region audits. Many edge-first hosting patterns overlap with edge backend patterns used in low-latency consumer stacks.

Cost optimization levers

• Lifecycle rules to transition cold data and purge obsolete snapshots.
• Spot/preemptible instances for noncritical training and batch jobs with checkpointing.
• Right-size serving tiers: set latency SLOs and measure cost per prediction to enable chargeback.

Operational playbook — how to roll this out

Turn the roadmap into an operational program with three tracks: discover, harden, operationalize.

Discover (0–6 weeks)

• Map critical datasets and owners; register them in the catalog.
• Run lightweight lineage capture on top pipelines (OpenLineage) to establish baseline provenance.
• Define performance and trust SLOs for top models (freshness, drift, cost per inference).

Harden (6–20 weeks)

• Implement schema registry checks, contract tests in CI, and ingestion guards for producers.
• Set up data quality assertions and drift detectors for top features.
• Migrate critical features to a dedicated serving layer with caching and cost controls.

Operationalize (ongoing)

• Automate impact notifications via lineage: a change in a producer triggers an owner workflow and a temporary block for dependent retraining until validation.
• Integrate cost KPIs into the catalog so teams see storage/compute cost per dataset.
• Run quarterly “data health” reviews tied to business metrics and model performance.

Concrete example: feature drift incident and how infrastructure prevents it

Scenario: A production recommender’s click-rate drops 18% after a supplier changes a CSV schema. Without lineage and contracts, the incident takes days to trace and costly model rollbacks happen.

With the roadmap in place:

1. Schema registry blocks the incompatible write and notifies the supplier’s owner.
2. Lineage-based impact analysis identifies two models that consume that CSV-derived feature and creates an incident ticket with owner contacts.
3. Data quality checks detect missing categories and trigger a rollback of the nightly job; cached features continue serving fresh predictions.
4. Cost of investigation is reduced; model performance recovers within hours instead of days.

KPIs and dashboards to track

• Catalog coverage: % critical datasets registered (goal: 95% in 6 months).
• Lineage completeness: % of dataset updates with captured lineage edges.
• Data quality pass rate: % of pipeline runs passing all assertions.
• Model input drift rate: % of features exceeding drift thresholds per week.
• Cost per prediction and cost per training epoch by model and dataset.

Technology checklist — pragmatic toolset options

Prioritize open standards and interoperable components to avoid vendor lock-in and maximize observability.

• Catalog / Metadata: DataHub, Amundsen, or a cloud-managed catalog.
• Schema Registry: Confluent Schema Registry or cloud-native equivalents.
• Lineage: OpenLineage + Marquez integration with orchestration tools.
• Quality/Testing: Great Expectations, Soda, or in-house assertions hooked into CI.
• Orchestration: Airflow / Dagster with metadata hooks.
• Feature Serve: Feast or cloud-managed feature store, plus Redis/Vector DB for low-latency reads.
• Observability: Prometheus/OpenTelemetry for infra + Monte Carlo or custom dashboards for data SLAs. For enterprise-grade observability patterns see cloud-native observability playbooks.

Future trends to plan for (2026–2028)

• AI-first data contracts: Contracts that include model-facing semantics (e.g., bias constraints, calibration targets) will become standard.
• Synthetic augmentation governance: As synthetic data is used more for training, provenance and labeling of synthetic vs. real inputs will be required for audits; see discussion on operationalizing provenance for synthetic assets.
• Continual verification: Continuous model verifiers will run downstream of lineage systems to assert end-to-end behavior in production.
• Stronger regulation: Expect stringent requirements for provenance and the ability to explain inputs used in high-stakes models.
• Mixed reality & edge testing: model inputs from new sensors (including MR) will require novel capture and labeling workflows; teams should browse MR playtesting guidance (mixed reality playtesting).

Practical checklist — first 90 days

1. Register your top 20 datasets and add owners and SLA metadata to the catalog.
2. Add a schema registry and enforce compatibility checks in producer CI pipelines.
3. Instrument OpenLineage on critical pipelines; capture logical and physical lineage.
4. Deploy data quality assertions for top features and set drift alerts tied to incident playbooks.
5. Measure and publish cost-per-prediction for one high-impact model and set a cost SLO; consider billing and micro-payments lessons from developer platforms (micro-payments analysis).

Actionable takeaways

• Start metadata-first: the catalog is the single most leveraged investment for AI readiness.
• Make pipelines declarative and metadata-driven: this enables automated testing, lineage capture, and cost controls.
• Instrument lineage and observability early: it shortens incident MTTR and supports regulatory audits. Enterprise observability patterns are discussed in industry playbooks.
• Align hosting with SLAs: choose storage/serving tiers and inference patterns to balance latency and predictable costs; for edge-first hosting see edge backend patterns.

Closing — where to begin

Salesforce’s research is a timely reminder: weak data management isn't just an organizational problem — it's an infrastructure one. Solving it requires a deliberate, infrastructure‑centric program that couples cataloging, metadata-driven pipelines, lineage capture, and hosting patterns optimized for cost and performance.

If you’re responsible for production ML or enterprise analytics, start by running a 6-week catalog sprint for your top datasets and instrumenting lineage on the most critical pipelines. From there, enforce schema contracts in CI, add data quality gates, and match your hosting architecture to the required latency and cost profile.

Call to action: For a tailored 90-day plan aligned to your stack and cost targets, schedule a technical review with your infrastructure team. Prioritize catalog coverage and lineage capture first — you’ll reduce risk and cut mean time to recovery for AI incidents within weeks.
