AWS Glue & AWS Step Functions Azure Data Factory (ADF)

From AWS Glue & Step Functions to Azure Data Factory (ADF).

The 30-Second Mental Model Shift

In AWS, ETL and orchestration are split between AWS Glue (Spark data processing) and AWS Step Functions (state machine orchestration). Azure Data Factory combines both: visual pipeline orchestration DAGs + visual Mapping Data Flows (Spark) in one tool.

1. Architectural Mechanism Comparison

AWS (What You Know)

AWS Glue & AWS Step Functions

AWS Glue provides serverless Spark ETL jobs + Glue Catalog. Step Functions coordinates visual state machines using JSON State Language (ASL).

Key Architecture Strengths:
  • Serverless Spark ETL execution without managing EMR clusters.
  • AWS Glue Data Catalog provides centralized Hive-compatible metastore.
  • Step Functions coordinates across 200+ AWS services.
AZURE (How It Works)
Mastery Target

Azure Data Factory (ADF)

Unified serverless visual ETL and orchestration service with 100+ native connectors, Mapping Data Flows (Spark), and Self-Hosted IR for hybrid on-prem networks.

Why Azure Built It This Way:
  • 100+ native connectors with visual drag-and-drop pipeline canvas.
  • Self-Hosted IR acts as an outbound-only port 443 gateway for on-prem corporate databases.
  • Unified scheduling (Tumbling Window, Storage Events, Chronological).

2. Integration Runtimes (IR) & Mapping Data Flows

The Integration Runtime executes pipeline activities. Azure IR manages serverless cloud movement; Self-Hosted IR securely connects private on-premise networks with outbound-only HTTPS (port 443); Mapping Data Flows compiles visual graphs to Apache Spark.

Real-World Analogy

Like a secure armored courier that can enter high-security bank vaults (on-prem) without leaving the back doors unlocked.

Key Mechanics
  • Self-Hosted IR (SHIR): Outbound-only port 443 (zero inbound firewall holes required).
  • Azure IR: Managed serverless cloud compute auto-allocating Data Integration Units (DIUs).
  • Mapping Data Flows: Drag-and-drop transformations compiled into Spark Scala jobs.

5. Paradigm Shift Gotchas: Traps to Avoid in AZURE

Gotcha #1
tip

Self-Hosted IR Outbound Port 443 Only

The Trap:

Network engineers often worry that connecting Azure to on-prem databases exposes internal networks.

How to Avoid It:

Explain that Self-Hosted IR initiates outbound-only HTTPS to Azure; incoming ports remain 100% closed.
