Medallion Architecture
Medallion architecture isn't a one-size-fits-all solution. It's a framework that's meant to be adapted. As Data Architects, our job isn't just to move data through these stages. It's to sculpt these stages to fit our unique business contexts.
From Raw Data to Insights
🥉 Bronze Layer: The raw data's initial landing spot. Think of it as data in its natural habitat, untouched and wild.
🥈 Silver Layer: After undergoing rigorous cleaning, validation, and schema systematization, data moves to the Silver layer. Here, it is polished and primed for analysis, becoming a reliable resource for deeper insights.
🥇 Gold Layer: The final refinement stage where data is aggregated, modeled, and tailored to suit various business scenarios. In the Gold layer, data achieves its highest value, becoming directly actionable and integral to strategic decision-making.
What is the Medallion Architecture?
The Medallion Architecture is a data engineering approach that organizes data in a layered structure to deliver quality, scalability and usability. The Medallion approach is structured into Bronze, Silver, Gold layers. In this, data engineers can take raw datasets (Bronze), clean and enrich them (Silver) and then transform them into prepared datasets for analytics and reports (Gold). By removing complexity, ensuring the proper use of the data, and making it ready for better use for analytics and AI / ML.
Ilum supplies prebuilt templates and dashboards for each layer of the Medallion Architecture, eliminating the need for massive custom development. These tools enable you to jumpstart faster and leave flexibility to customize i.e. whether monitoring ingestion of raw data or seeking foresight out of advanced analytics.
Automation Across Data Pipelines
Ilum helps automate process like data validation, schema evolution, as well as orchestration of complex transformations in Medallion Architecture pipeline. Ilum takes advantage of Spark-based workflows and integrated monitoring tools to reduce manual processes, error rates, and data quality inconsistencies at scale. By using these automated works, the processing gets faster without compromising your pipeline.

Interactive Exploration with Jupyter Notebooks
Transform your Medallion Architecture with our integrated Jupyter Notebook template. This interactive environment enables data scientists and engineers to access and work across the Bronze, Silver, and Gold layers, accelerating prototyping and in-depth data analysis. The template is designed to enforce best practices, ensuring that every transformation and analytical model meets rigorous data quality and governance standards.
Learn MoreSimplify Governance and Compliance
Data governance is integral to the Medallion Architecture. Our platform enables automated tracking of data lineage and version control with schema enforcement at every stage–from raw to refined data. This makes it easy to comply with regulatory standards while giving you full transparency and auditability, providing assurance that your data is safe and reliable at all times.
Learn MoreEnsure Data Quality and Consistency
Quality data is the foundation of effective analytics. Within the Medallion Architecture, our solution embeds rigorous validation checks and real-time error handling throughout the Bronze, Silver, and Gold layers. Automated profiling and continuous monitoring catch inconsistencies early—so you can be confident that each dataset is accurate and reliable before it drives your business insights. This proactive quality assurance minimizes downstream issues and empowers you to make data-driven decisions with certainty
Learn MoreAdaptive Scalability for Every Medallion Layer
Handling vast and varying data workloads is central to this architecture. With a Kubernetes-native design and integrated Spark workflows, our solution dynamically allocates compute and storage resources tailored to the needs of each stage. Whether processing high-velocity raw data in the Bronze layer or executing complex transformations in the Silver layer, our system scales ensuring optimal performance and resource efficiency even as your data demands grow.
Learn MoreOptimized Performance & Enterprise-Grade Scalability
From small scale deployments to enterprise level operations, the Medallion Architecture must perform flawlessly under any workload. Our platform’s advanced scheduling and resource allocation capabilities ensure that each layer of your data pipeline operates at peak efficiency—even during demand spikes. With built-in performance monitoring and dynamic orchestration, you can expand your data operations confidently, knowing that every part of your pipeline is optimized for speed, resilience, and cost-effectiveness.
