Introduction
In today’s data-driven world, businesses need powerful tools to manage, process, and analyze their data efficiently. Azure Data Factory (ADF) and Azure Databricks are two leading solutions in Microsoft’s cloud ecosystem, but they serve different purposes.
While ADF is designed for data integration and ETL (Extract, Transform, Load) workflows, Databricks is built for big data analytics, AI, and machine learning. These services fall under the broader category of Azure Data Services, which offers comprehensive solutions for data management, transformation, and analytics.
This article explores the key differences, use cases, and how to decide which tool best suits your needs.
What is Azure Data Factory (ADF)?
Azure Data Factory is a cloud-based data integration service that enables users to move and transform data at scale. It acts as an ETL tool that automates data movement between various sources and destinations.
