Microsoft-First, Not Microsoft-Only: The Enterprise Hybrid Integration Guide
By Errin O'Connor, Founder & Chief AI Architect, EPC Group | Updated April 2026
Every enterprise has a hybrid technology stack. Fortune 500 organizations that EPC Group advises cannot rely on a single-vendor environment. They often use:
- Salesforce with Dynamics
- SAP with Azure
- Snowflake with Fabric
Our role is to make Microsoft the intelligent layer that connects, analyzes, and governs data across all these systems.
This guide outlines the actual integration patterns we implement in production.
Why "Microsoft-First" Is the Right Strategy
Microsoft-first does not mean Microsoft-only. It means that Microsoft Azure, Power BI, Microsoft Fabric, Copilot, and Microsoft 365 form the strategic platform — the analytics, AI, collaboration, and governance backbone — while operational systems from other vendors feed into and integrate with that platform.
This approach is effective because Microsoft holds a unique place in the enterprise stack. It serves as:
- Productivity platform: Outlook, Teams, Office
- Analytics platform: Power BI, Fabric
- AI platform: Copilot, Azure OpenAI
- Governance platform: Purview, Defender
- Cloud platform: Azure
No other vendor covers this range. By making Microsoft the strategic backbone, every other system becomes an integration point instead of a standalone solution.
Treating every technology as equal and creating point-to-point integrations can lead to high maintenance costs. This method is difficult to manage and does not effectively support enterprise AI initiatives. EPC Group has seen this issue frequently. A Microsoft-first approach provides:
- Streamlined integrations
- Lower maintenance costs
- Better support for AI initiatives
- Lower total cost of ownership (TCO)
- Faster time-to-insight
- Stronger governance posture
Integration Pattern 1: Salesforce CDC to Microsoft Fabric
Salesforce is the most common non-Microsoft system used by our enterprise clients. The challenge lies not in connecting Power BI to Salesforce—this is possible—but in doing so at an enterprise scale. Key concerns include:
- Avoiding API limits
- Minimizing latency issues
- Preserving data lineage
EPC Group's Production Pattern
- Salesforce Change Data Capture (CDC): Enable CDC on key Salesforce objects (Account, Opportunity, Contact, Case, custom objects). CDC publishes change events to the Salesforce event bus in near-real-time.
- Azure Event Hubs: A lightweight integration layer subscribes to Salesforce CDC events and publishes them to Azure Event Hubs. This decouples Salesforce from the analytics pipeline and provides buffering for volume spikes.
- Fabric Eventstream: Fabric Eventstream ingests from Event Hubs into OneLake in Delta format. Automatic schema evolution handles Salesforce field additions without pipeline breaks.
- Fabric Lakehouse: Salesforce data lands in a Bronze layer (raw CDC events), is transformed in Silver (business logic, deduplication, type casting), and joined with Microsoft data in Gold (unified customer 360, revenue analytics).
- Power BI Semantic Model: A Direct Lake semantic model on the Gold layer provides sub-second query performance for executive dashboards combining Salesforce pipeline data with Microsoft 365 collaboration metrics.
This approach addresses the common issue of direct Power BI-to-Salesforce connectors. These connectors often reach API limits, offer slow refresh rates, and create unmanageable data copies.
Our production implementations effectively manage:
- 11,000+ Salesforce records at engagement scale
- 15-minute data freshness
Integration Pattern 2: SAP BW to Power BI via Fabric
SAP is essential for finance and operations for many EPC Group clients. This is especially true in the manufacturing, healthcare, and financial services sectors.
One of the most requested integration patterns we provide is connecting SAP BW (Business Warehouse) to Power BI.
- SAP BW connector in Fabric Data Factory: Native connector that extracts data from SAP BW InfoProviders, InfoCubes, and DSOs without custom ABAP development. Supports delta extraction for incremental loads.
- SAP HANA direct query: For real-time operational reporting, Power BI connects directly to SAP HANA views through the on-premises data gateway. EPC Group uses this for manufacturing floor dashboards where 1-minute latency matters.
- SAP OData services to Fabric: For SAP S/4HANA Cloud, OData APIs provide a modern integration path into Fabric pipelines. EPC Group configures incremental extraction using change tracking timestamps to minimize SAP system load.
- Azure Data Factory SAP CDC: For high-volume SAP extraction, Azure Data Factory's SAP CDC connector provides near-real-time replication of SAP tables into Fabric OneLake. This is the pattern we recommend for enterprise-scale SAP-to-Fabric integration.
The main takeaway from our SAP integration experience is that the technical connector is rarely the bottleneck. The real challenge is modeling SAP's complex data structures.
These structures include:
- Hierarchies
- Currencies
- Fiscal calendars
These elements must be translated into Power BI semantic models that business users can easily understand.
EPC Group's expertise in SAP and Power BI covers both aspects:
- Technical connectors
- Data modeling
Integration Pattern 3: Snowflake + Fabric Mirroring
Many EPC Group clients have made significant investments in Snowflake for data warehousing. The key question is not, "Should we replace Snowflake with Fabric?" Instead, it is, "How can we maximize the benefits of both?"
Fabric Mirroring offers a solution to this challenge.
Fabric Mirroring creates a synchronized copy of Snowflake data in OneLake. It eliminates the need to build or maintain data pipelines. Changes made in Snowflake are automatically updated in Fabric.
This feature allows for Power BI Direct Lake queries against Snowflake-sourced data. It offers the performance of local Delta tables. As a result, it removes the usual tradeoff between data freshness and query performance.
When Fabric Mirroring Makes Sense
- Snowflake is the established data warehouse and migration is not planned
- Power BI is the enterprise BI standard and needs Snowflake data at scale
- AI workloads in Fabric (Copilot, ML models) need access to Snowflake-managed data
- Data governance via Purview needs to span Snowflake and Microsoft data
- Eliminating data pipeline maintenance cost is a priority
EPC Group has implemented Fabric Mirroring for clients using Snowflake warehouses of 10TB or more. This solution offers a unified analytics experience. Business users do not need to know or care if data comes from Snowflake or native Fabric sources.
The governance layer includes:
- Purview sensitivity labels
- Row-level security
- Data lineage
These features work the same way across both data sources.
Integration Pattern 4: Databricks Unity Catalog + Fabric
Databricks is the top choice for data engineering and machine learning workloads in many organizations that EPC Group advises. The integration with Fabric highlights their complementary strengths:
- Databricks: Ideal for complex data engineering tasks, including Spark-based ETL, ML model training, and streaming.
- Fabric: Best for business analytics, featuring tools like Power BI, Copilot, and Purview governance.
- OneLake shortcuts to Databricks Unity Catalog: Fabric can create shortcuts that provide read access to Delta tables managed by Databricks Unity Catalog. No data copying — Power BI queries traverse the shortcut to Databricks-managed storage.
- Databricks writing to OneLake: Databricks notebooks can write directly to OneLake storage using the ABFS (Azure Blob File System) driver, enabling Databricks-processed data to appear instantly in Fabric lakehouses.
- Unified Delta Lake format: Both Fabric and Databricks operate on Delta Lake format, eliminating format conversion overhead and ensuring data fidelity across platforms.
The EPC Group architecture principle for Databricks + Fabric is straightforward. Use Databricks where its Spark engine performs best. This includes:
- Complex transformations
- ML training
- Streaming
On the other hand, use Fabric where its business platform excels. This includes:
- Power BI visualization
- Copilot AI assistance
- Purview governance
- Business user self-service
This approach is not a competition; it represents a complementary architecture.
Integration Pattern 5: Oracle to Azure for Analytics
Oracle databases, whether on-premises or in Oracle Cloud, play a crucial role in enterprise operations. This is especially true in financial services and government sectors. EPC Group's Oracle integration patterns aim to make Oracle operational data accessible for Microsoft analytics. This is done without disrupting applications that depend on Oracle:
- Seamless data access
- Enhanced analytics capabilities
- Minimal disruption to existing applications
- Oracle CDC via Fabric Data Factory: Change data capture from Oracle databases into Fabric OneLake for near-real-time analytics
- Oracle GoldenGate to Event Hubs: For clients with existing GoldenGate investments, we route change streams through Azure Event Hubs into Fabric
- Power BI DirectQuery to Oracle: For low-latency operational dashboards through the on-premises data gateway
- Oracle Autonomous Database + Azure Arc: For Oracle Cloud environments, Azure Arc provides unified management and monitoring alongside native Oracle workloads
Governance Across the Hybrid Stack
The most important part of hybrid integration is unified governance. Data flows from Salesforce through Fabric into Power BI. This data needs consistent classification, lineage, and access control. EPC Group uses Microsoft Purview as the governance backbone for hybrid environments:
- Consistent classification
- Data lineage tracking
- Access control management
- Multi-source scanning: Purview scans and classifies data across Azure, Snowflake, SAP, Salesforce, Oracle, AWS S3, and Google BigQuery from a single governance plane
- Unified data catalog: Business users find and understand data regardless of source system through a single searchable catalog
- Sensitivity labels: Classification labels applied in Purview propagate to Power BI reports, Fabric notebooks, and Copilot responses
- Data lineage: End-to-end lineage from source system (Salesforce record, SAP table, Snowflake view) through transformation to consumption (Power BI report, Copilot answer)
- Access governance: Unified access reviews and entitlement management across the hybrid stack through Entra ID and Purview policies
This governance approach is what enables our clients in regulated industries to confidently build analytics and AI on hybrid data — they can demonstrate to auditors exactly where data came from, how it was classified, who accessed it, and what controls were applied at every step.

Frequently Asked Questions
Does EPC Group only work with Microsoft technologies?
No. EPC Group is Microsoft-first, not Microsoft-only. While Microsoft is our primary technology ecosystem and deepest expertise area, we have extensive integration experience with Salesforce, SAP, Snowflake, Databricks, Oracle, AWS, Google Cloud Platform, and dozens of industry-specific platforms. Our engagements routinely involve connecting Microsoft analytics and AI capabilities with non-Microsoft data sources, CRMs, and operational systems. The real world is hybrid, and so are our architectures.
Can Power BI connect to Salesforce data effectively?
Yes. EPC Group has built production Power BI deployments sourcing data from Salesforce for Fortune 500 clients. The most effective pattern uses Salesforce CDC (Change Data Capture) events streamed through Azure Event Hubs into Microsoft Fabric OneLake, where Power BI consumes the data with near-real-time freshness. This approach avoids the API call limits and performance issues of direct Power BI-to-Salesforce connectors while enabling semantic modeling across Salesforce and Microsoft data in a unified lakehouse.
How does Microsoft Fabric work with Snowflake?
Microsoft Fabric supports Snowflake integration through multiple patterns: Fabric Mirroring (preview) for near-real-time data synchronization without data movement pipelines, Fabric Data Factory pipelines with native Snowflake connectors for batch ETL, and OneLake shortcuts that provide virtualized access to Snowflake-managed data. EPC Group recommends Fabric Mirroring for analytics workloads where Snowflake remains the operational data store and Fabric serves as the semantic and AI layer.
What is the typical timeline for a hybrid integration architecture engagement?
EPC Group's hybrid integration engagements typically run 8-16 weeks depending on complexity: 2-3 weeks for discovery and architecture design (mapping data sources, integration patterns, security requirements), 4-8 weeks for implementation (data pipelines, semantic models, security configuration), 2-3 weeks for testing and optimization, and 1-2 weeks for knowledge transfer. Organizations with existing Azure infrastructure and well-documented source system APIs are on the shorter end; greenfield Azure + multiple legacy source systems are on the longer end.
How does EPC Group handle data governance across hybrid Microsoft and non-Microsoft environments?
Microsoft Purview is the governance backbone for hybrid environments. EPC Group configures Purview to scan and classify data across Azure, Snowflake, SAP, Salesforce, Oracle, and AWS S3 from a single governance plane. Sensitivity labels applied in Purview propagate to Power BI reports, Fabric lakehouses, and Copilot responses — ensuring that governance policies follow the data regardless of where it originates. This unified governance approach is critical for regulated industries where data lineage and classification must span the entire technology stack.
