Azure Data Factory
Azure Data Factory is Microsoft's cloud-based data integration service that automates the movement and transformation of data between different data sources and destinations.
Overview
Azure Data Factory works like a cloud-based data assembly line that helps you collect, move, and transform data from different sources. Think of it as a factory that takes raw data from various places (like databases, files, or software applications), processes it according to your rules, and delivers it where you need it.
The service allows you to create data-driven workflows (called pipelines) that can orchestrate and automate data movement and data transformation. These pipelines can run on a schedule, in response to events, or be triggered manually. You can move data between on-premises systems and the cloud, or between different cloud services.
One of its key features is the ability to handle both big data and SQL workloads. It includes a visual interface for designing your data flows, making it easier to build complex data integration processes without writing extensive code.
Data Factory also manages the reliability and monitoring of your data pipelines, providing detailed logging and alerts when something goes wrong. It can scale automatically to handle large volumes of data and includes built-in support for data governance and compliance.
Example uses
Data Warehousing: Regularly load data from various sources into a central data warehouse for analysis.
ETL/ELT Processing: Transform raw data into a format suitable for analysis or reporting.
Data Migration: Move data from legacy systems to modern cloud storage or databases.
Real-time Analytics: Create pipelines that process and analyze data as it arrives from different sources.
Integration with other Azure services
Data Factory works seamlessly with many Azure services:
- Azure Blob Storage: Source or destination for data files
- Azure SQL Database: Move and transform relational data
- Azure Synapse Analytics: Load and process data for analytics
- Azure HDInsight: Process big data workloads
- Power BI: Create visualizations from processed data
- Azure Key Vault: Securely store connection credentials
