Medallion Architecture in MS Fabric | DynaTech Systems

The promise of real-time data sounds simple: act the moment things happen. But in practice, most enterprises are stuck. Disconnected systems, data silos, and brittle ETL pipelines turn live data into yesterday’s news. Businesses are collecting terabytes of streaming data from IoT sensors, apps, CRMs, and websites—but by the time it’s usable, it’s already obsolete. 

Let’s make it concrete: 

Stat Alert: According to IDC, businesses that can analyze data in real-time outperform their peers by 5x in customer acquisition and retention rates. Yet, more than 60% of enterprises still rely on batch processing for critical decision-making. 

That’s the gap. 

Enter Microsoft Fabric Real-Time Intelligence—a modern, unified analytics platform that doesn’t just process streaming data; it transforms it. And at the heart of this transformation lies a brilliant architecture pattern: the Medallion Architecture. 

This isn't just another data warehouse schema. It’s a structured, scalable way to ingest, refine, and surface data in real time, using layers: Bronze (raw), Silver (clean), and Gold (business-ready). When implemented correctly in Microsoft Fabric, it allows businesses to go from “just capturing data” to “always ready to act.” 

In this blog, we’ll take you deep into how Medallion Architecture works in Fabric’s real-time intelligence engine, how to implement it, why it matters—and how DynaTech, a top 1% Microsoft Partner, helps organizations lead this data evolution. 

Why Real-Time Data is a Game-Changer for Modern Enterprises 

In today’s hyper-connected business landscape, real-time data is not just a technological advantage—it’s a competitive imperative. Enterprises that can sense, analyze, and respond instantly to changing data signals outperform those still operating on batch cycles and outdated pipelines. 

Let’s have a look at some real numbers: 

But here's the challenge: streaming data is raw, messy, and volatile. If it is unstructured and cannot be governed quickly, it becomes more of a liability than an asset. 

That’s where the Medallion Architecture in Microsoft Fabric Real-Time Intelligence steps in. It renders an elevated, layered approach to wrangling this chaos—letting you ingest, refine, and visualize streaming data all in one pipeline. 

And this isn’t just theoretical. With solutions like KQL Database, Eventstream, and Data Activator, Fabric creates a canvas for action—where real-time data doesn’t just sit in dashboards, but triggers decisions, alerts, and automations. 

What is Medallion Architecture? 

The Medallion Architecture is a kind of design pattern that structures data processing into three logical layers: Bronze, Silver, and Gold. Originally popularized by the data lakehouse community, this 3 layered approach has now found a powerful home in Microsoft Fabric’s Real-Time Intelligence ecosystem. 

Here’s how it works: 

Bronze Layer – Raw & Streaming Ingestion 

This is the first checkpoint for your data. It captures everything: raw telemetry, user logs, sensor readings, e-commerce events, social signals, etc. 

Tools in Fabric:

• Eventstream to enable data ingestion 
• KQL Database as the initial store

Characteristics:

• Immutable 
• Schema-flexible 
• Low-latency ingestion

Use Case: Capturing raw POS transactions from 1000+ retail stores every second. 

Silver Layer – Clean & Filtered Data 

Here, your raw streams are transformed: duplicates removed, columns standardized, missing values handled, and schema normalized. 

Tools in Fabric:

• KQL or Spark to enable transformations 
• Stream Processing Rules for filtering 

Characteristics: 

• Light aggregations 
• Quality checks 
• Event-time alignment

Use Case: Creates clean, consistent order records with product, prices, as well as, location metadata applied. 

Gold Layer – Business-Ready Insights 

Here, magic happens. Data is now ready for decisions—enriched, joined, and modeled to feed dashboards, reports, and automation triggers. 

Tools in Fabric:

• Power BI for live dashboards 
• Data Activator for proactive alerts 
• DirectLake access to analytics-ready data

Characteristics:

• High-value, curated datasets 
• Role-specific metrics 
• Real-time triggers

Use Case: Alerting a logistics manager when delivery time KPIs drop below threshold in real time. 

Such architecture enables incremental transformation. You don’t need to reprocess an entire dataset when something changes upstream. That’s key when you’re handling real-time data at scale. 

Key Insight: The combination of Medallion Architecture with Fabric’s Real-Time Intelligence is what makes this ecosystem enterprise-ready—and future-proof. 

Inside Microsoft Fabric Real-Time Intelligence — Tools That Power the Medallion Architecture 

The brilliance of Microsoft Fabric is not in its data unification—but in how naturally it supports the Medallion Architecture through an ecosystem of real-time tools. Here are the core components that enable data flow in the Bronze, Silver, and Gold layers:

1. Eventstream — The Real-Time Ingestion Backbone

Eventstream is Fabric’s native pipeline to capture streaming data from sources like Azure Event Hubs, Kafka, or IoT devices. 

• Use in Bronze Layer 
• Supports transformation rules on the fly 
• Connects directly to KQL Databases, Lakehouses, and Data Activator 

2. KQL Database — For Immediate Querying & Storage

KQL DB is optimized for log-style data, perfect for capturing unstructured or semi-structured data in the Bronze layer. 

• Sub-second queries using Kusto Query Language (KQL) 
• Great for alerting, monitoring, and pattern matching 
• Plays a role in both Bronze and Silver stages 

Highlight: KQL lets you enrich and filter streams before they hit analytics dashboards. 

3. Lakehouse — Transform & Store at Scale

The Lakehouse brings structured transformation into the picture, using Spark notebooks, shortcuts, and Delta tables. 

• Crucial for the Silver-to-Gold transition 
• Supports data modeling and large-scale joins 
• Tied tightly with Power BI and DirectLake

4. Data Activator — From Dashboards to Decisions

This is where Gold-layer data comes alive. Data Activator listens for patterns in real-time and automatically triggers alerts, actions, or business workflows. 

• Integrated with Power Automate 
• No-code rules and proactive decision-making 
• Works across KQL DB, Eventstream, and Lakehouse

5. Power BI Real-Time Dashboards

Data, once refined and modeled, is surfaced instantly via Power BI’s DirectLake connectivity. There’s no duplication—data is queried in-place. 

• No scheduled refreshes needed 
• Supports pinning of KQL-based visuals 
• Powered by semantic models from the Gold layer

This combination of tools enables end-to-end real-time intelligence—with each Fabric component slotting naturally into its Medallion layer. 

Medallion in Action — A Real-Life Data Flow in Fabric 

To truly appreciate the power of the Medallion Architecture in Fabric Real-Time Intelligence, let’s walk through a real-world scenario. Here’s how a global retail chain might use it to improve supply chain visibility and operational responsiveness. 

Use Case: Real-Time Inventory Optimization Across Stores 

Bronze Layer – Raw Event Ingestion 

• Data Source: Every time a product is scanned at checkout or received at a warehouse, an event is pushed to Eventstream. 
• Sources: Azure Event Hub, IoT Edge devices from smart shelves 
• Storage: Data lands immediately into a KQL Database for sub-second querying.

Example: ProductID, Location, Timestamp, StockBefore, StockAfter 

Silver Layer – Cleaned, Filtered, and Enriched 

• Transformation Rules: Only capture events where inventory levels drop below threshold or when anomalies are detected (like sudden depletion). 
• Tools: Data enriched with warehouse metadata, product categories, and time zone adjustments using Spark in Lakehouse or KQL queries. 
• Output: Refined tables streamed to Delta Lake with clean schema.

Output Table: ProductID, StoreID, Category, CurrentStock, Threshold, Timestamp 

Gold Layer – Business Insights & Triggers 

• Dashboards: Power BI displays live “Low Inventory Heatmaps” by store or region. 
• Data Activator: Triggers an alert to the regional manager or even auto-initiates a restock request via Power Automate if stock is below 10 units. 
• Analytics: Predictive modeling identifies recurring stockout patterns by time of day, product line, or location.

Insight: This pipeline turns raw, noisy signals into predictive, automated decisions — within seconds of an event occurring in the physical world. 

Benefits of Medallion Architecture  

Medallion Architecture + Fabric = Scalable Real-Time Brilliance

Each layer (Bronze, Silver, Gold) operates independently. This decreases risk and enables modular maintenance, and fastens data experimentation. 

• New data sources can be tested in Bronze without impacting business dashboards. 
• Business teams can consume Gold layer insights with guaranteed schema cleanliness.

This separation is key for enterprise-grade scalability and compliance. 

2. Real-Time Data Availability

Thanks to Eventstream, KQL DB, and Power BI DirectLake, data is usable within milliseconds after ingestion. 

Stat to Know: Gartner predicts 70% of organizations will shift from batch to streaming architectures by 2025. 

3. Optimized Storage & Processing Cost

• Raw telemetry in KQL DB is compressed and cost-efficient. 
• Refined data moves only when necessary. 
• No data duplication thanks to Power BI’s DirectLake capability.

Insight: You only pay for what’s used—no over-engineering or redundant storage. 

4. Proactive Automation

Data Activator and Power Automate enable business users to react to data without the need of writing a single line of code. 

• Inventory running low? Alert the ops team. 
• Delay in shipments? Auto-notify the logistics vendor. 
• Hike in website traffic? Trigger dynamic pricing. 

5. Enterprise Security & Governance

Microsoft Fabric ensures role-based access, tracking of lineage, and sensitivity labels from raw to gold.
