GCP to Azure Data Engineering Bridge
Translate your existing knowledge of BigQuery, GCS, Pub/Sub, and Composer into Azure Synapse, ADLS Gen2, Event Hubs, and ADF without watching 10-hour introductory videos.
Data Engineering Translation Tracks

Data Lake & Object Storage
From GCS flat object buckets to ADLS Gen2 POSIX Hierarchical Namespaces.
In GCS, folders don't actually exist—they are just strings with slashes. In ADLS Gen2 with HNS, folders are real physical file system entities. Renaming a directory with 500,000 files in GCS executes 500,000 copy/delete operations; in ADLS Gen2, it takes 5 milliseconds!
Modern Data Warehousing
From BigQuery dynamic Dremel slots to Azure Synapse 60-Distribution MPP & Serverless T-SQL.
In BigQuery, everything is serverless and auto-managed. In Azure Synapse, you have two distinct superpowers: 1) Serverless SQL Pools (matches BigQuery's on-demand $5/TB query over Parquet files with zero VMs), and 2) Dedicated SQL Pools (fixed MPP engine with 60 storage distributions where you must explicitly choose Hash, Replicated, or Round-Robin table strategies).
Real-Time Streaming & Message Ingestion
From Pub/Sub per-message ACK model to Azure Event Hubs append-only partition logs.
In GCP Pub/Sub, you don't worry about partitions, and messages disappear once acknowledged. In Azure Event Hubs, you must think in Apache Kafka terms: fixed parallel Partitions (1-32+), Consumer Groups tracking offsets, and an immutable 90-day time buffer allowing you to rewind and replay historical data.
Pipeline Orchestration & ETL
From Cloud Composer (Apache Airflow Python DAGs) to Azure Data Factory (Visual Serverless Pipelines).
Cloud Composer requires maintaining a GKE cluster running Airflow workers in Python ($250+/month baseline even when idle). Azure Data Factory is 100% serverless ($0 baseline) with a visual drag-and-drop canvas and the Self-Hosted Integration Runtime that acts as an outbound-only secure gateway to your private corporate databases.
Service Accounts, IAM & Local App Access
From GCP Service Accounts & JSON Keys to Microsoft Entra ID Service Principals, Client Secrets & DefaultAzureCredential.
In GCP, you create a 'Service Account' and download a JSON key file. In Azure, you register an 'App Registration' in Microsoft Entra ID, generate a 'Client Secret' (or use pure `az login`), and grant an Azure RBAC role (e.g. `Storage Blob Data Contributor`) to its 'Service Principal'. In Python, `DefaultAzureCredential()` gives you the exact same automatic multi-environment discovery as Google's ADC!
