Fabric

Microsoft Fabric and data platform engineering.

Fabric is powerful, but only when architecture is intentional. Without structure, Fabric becomes a collection of workspaces, pipelines, and datasets that are hard to govern.

L1 Consultancy designs Fabric platforms that are built for controlled growth and predictable operations.

Architecture
Patterns

BRONZE
SILVER
GOLD

We implement medallion layering to separate raw ingestion, refined transformations, and governed consumption. Bronze preserves source truth. Silver applies standardisation and quality controls. Gold provides curated structures for analytics and semantic modelling. This approach supports traceability, reprocessing, and consistent logic reuse.

Ingestion &
Transformation

SOURCE
VALIDATION
TARGET

We design ingestion with repeatability in mind, using metadata driven patterns where appropriate. Transformations are engineered for maintainability and validation. We implement data quality checks, reconciliation rules, and anomaly detection patterns so issues are identified before they reach reporting.

Refresh &
Partitioning

HISTORICAL DATA
PREVIOUS YEAR
CURRENT (INCREMENTAL)

Refresh strategy is designed to scale. We use partitioning and incremental logic where appropriate, manage refresh windows, and design pipelines to support concurrency. We ensure that refresh does not become a bottleneck as data volume and user adoption grows.

Capacity &
Environments

DEV
TEST
PROD

We design workspace segmentation aligned to your governance model and team structure. Dev, test, and production environments are separated with controlled promotion. Capacity planning considers refresh workload, concurrency, model size, and the behaviour of mixed workloads across the estate. We aim for predictable performance and clear operational ownership.

Monitoring &
Telemetry

We implement monitoring and telemetry patterns to observe refresh behaviour, failures, latency, and workload contention. Operations cannot be an afterthought in enterprise platforms. We design for observability.

Delivery output for this service

Typical deliverables include Fabric architecture blueprint, workspace and environment model, ingestion standards, transformation conventions, data quality framework, refresh and partition strategy, monitoring approach, and deployment and operating model recommendations.
