Data Integration Consulting: Connect Every Source Into a Unified Data Estate

The average enterprise runs 130+ SaaS applications, multiple databases, and legacy systems that don't talk to each other. Integration isn't optional — it's the engineering challenge that determines whether your data platform delivers value or collects dust.

Integration is the unglamorous work that makes data platforms actually work.

Everyone wants the lakehouse, the AI models, the real-time dashboards. Nobody wants to talk about the 47 source systems that need to feed them. But integration is where most data programs stall — not because the target platform lacks features, but because the connectors, pipelines, and sync mechanisms between sources and targets are fragile, poorly documented, or simply missing.

The problem intensifies as enterprises adopt multiple cloud platforms. A typical mid-market company might run Salesforce for CRM, D365 for ERP, Workday for HR, and Fabric or Snowflake for analytics. Each system has its own API patterns, authentication models, rate limits, and data change semantics. Connecting them reliably — with proper error handling, retry logic, and lineage tracking — requires specialized integration engineering.

Xylity matches integration engineers who understand both the source systems and the target platforms. Whether you need MuleSoft developers, Azure Data Factory specialists, or custom API engineers — our consulting-led matching evaluates candidates against your specific integration landscape.

What we deliver

Data integration consulting capabilities

Every integration engagement is staffed by engineers who understand your specific source systems, target platforms, and the connectivity patterns between them.

🔌

API Development & Integration

REST API design, GraphQL implementation, webhook handlers, and API gateway configuration. Custom connectors for systems without native integration support. Rate limiting, pagination handling, and error management built for production reliability.

🔄

ETL/ELT Pipeline Development

Batch and incremental data pipelines using ADF, Fabric Pipelines, dbt, Airflow, Fivetran, or custom orchestration. Source extraction, transformation logic, data quality gates, and loading into your target warehouse or lakehouse.

See ETL development →

Real-Time Data Sync

Change data capture (CDC), event streaming (Kafka, Event Hubs, Eventstreams), and near-real-time replication between operational and analytical systems. For use cases where batch latency is unacceptable — fraud detection, inventory tracking, live dashboards.

How we deliver

Integration engineers matched to your data landscape

Integration Assessment

We map your source systems, target platforms, data volumes, latency requirements, and current integration gaps. The matching starts from your specific landscape.

Specialist Matching

Engineers matched for your specific sources (Salesforce, D365, SAP) and targets (Fabric, Snowflake, Databricks). Platform-specific evaluation ensures production-ready skills.

Pipeline Development

Connectors, pipelines, and sync mechanisms built with proper error handling, retry logic, data quality gates, and monitoring. Production-grade from the start.

Monitor & Optimize

Pipeline performance monitoring, cost optimization, alerting setup, and runbook creation. Your integration layer is operational and your team owns it.

Who we serve

Integration expertise for enterprises and IT services companies

For enterprises

Data platform ready but sources still disconnected?

You've invested in Fabric, Snowflake, or Databricks — but the platform can only deliver value when it's connected to your operational systems. Xylity matches integration engineers who understand both your source applications (Salesforce, D365, SAP, Workday) and your target platform architecture. Consulting-led solutioning ensures the integration design fits your data strategy.

For IT services companies

Client needs integration specialists your bench doesn't have?

Integration projects require a specific combination of source-system knowledge (Salesforce APIs, D365 OData, SAP BAPIs) and target-platform skills (ADF, Fabric Pipelines, dbt). When your bench doesn't cover both sides, Xylity delivers curated integration profiles from our 200+ partner network. First profiles in an average of 4.3 days.

Common questions

Data integration consulting — answered

What's the difference between ETL, ELT, and API integration?
ETL (extract-transform-load) transforms data before loading it into the target. ELT loads raw data first, then transforms it inside the target platform — increasingly common with cloud warehouses. API integration connects systems in real-time or near-real-time for operational use cases. Most enterprise data strategies need all three. See our ETL pipeline development service for more detail.
How do you handle integration for systems with rate limits?
Rate limiting is one of the most common integration challenges — especially with Salesforce, HubSpot, and other SaaS APIs. Our engineers implement adaptive throttling, batch extraction strategies, and incremental sync patterns that maximize data freshness within API limits. For high-volume extractions, we use bulk APIs where available.
Should we use a managed iPaaS or custom integration?
Managed iPaaS platforms (MuleSoft, Boomi, Workato) work well for standard SaaS-to-SaaS connections with pre-built connectors. Custom integration is better for complex transformations, high-volume CDC, or when you need deep platform-native features. Most enterprises use both — iPaaS for standard flows and custom pipelines for complex data engineering workloads.
Can you integrate on-premises systems with cloud platforms?
Yes. Hybrid integration — connecting on-prem SQL Server, Oracle, or SAP instances with Fabric, Snowflake, or Databricks — is a core competency. We implement self-hosted integration runtimes, VPN-based connectivity, and CDC-based replication that keeps cloud platforms in sync with on-prem sources.
How do you handle schema changes in source systems?
Schema drift is one of the biggest operational risks in integration. Our engineers implement schema drift detection, automated alerting, and graceful handling strategies — whether that means auto-evolving the target schema, quarantining changed records, or triggering manual review workflows. The approach depends on your data governance requirements.
