Azure Data Factory (ADF) is a powerful, fully managed cloud service from Microsoft designed to simplify the process of moving, transforming, and orchestrating data at scale. Whether you are a developer, data engineer, or analyst, ADF provides a versatile platform to build data-driven workflows that automate data intake and processing across many sources and destinations. This blog introduces the core concepts, components, and benefits of Azure Data Factory, helping beginners understand how to get started easily.
What is Azure Data Factory?
Azure Data Factory is a serverless data integration platform built for modern cloud and hybrid data scenarios. It helps create automated data pipelines that extract data from diverse sources, perform transformations, and load the data into sinks (like data warehouses or lakes). You can think of ADF as a data orchestrator that ensures the right data moves efficiently and reliably between systems to enable analytics and reporting.
It supports a wide range of data sources from on-premises databases to cloud storage, SaaS applications, and big data stores. ADF also integrates well with other Azure services, making it ideal for enterprises adopting cloud data modernization.
Key Concepts and Components
Pipeline
A pipeline is a logical grouping of activities that perform a unit of work. For instance, a pipeline might copy data from an Azure Blob storage location and then transform it using a compute service like Azure Databricks. Pipelines enable you to manage the workflow as a single, coordinated job, running steps either sequentially or in parallel.
Activity
An activity represents a single task within a pipeline. There are many types, including but not limited to copying data, running a stored procedure, executing a data flow (for transformations), or invoking a REST endpoint. Activities are the building blocks to implement your data processes.
Dataset
Datasets represent data structures within your data stores, like tables or files. They act as inputs or outputs for activities, specifying what data is being processed.
Linked Service
A linked service is a connection string or configuration that defines the connection to a data source, destination, or compute resource. For instance, a linked service might connect ADF to an Azure SQL database or an Amazon S3 bucket. Learn More
Integration Runtime
This is the compute infrastructure that performs data movement and transformation. You can use Azure-hosted runtimes or self-hosted runtimes to securely access on-premises data. Learn More
Data Flows
Visual data transformation tools that let you build data transformation logic with a drag-and-drop experience. Data Flows in ADF execute on managed Spark clusters, handling large-scale data processing without coding Spark directly.
Triggers
Triggers define when pipelines run—on a schedule, in response to an event, or manually. You can automate your pipelines to execute daily, hourly, or based on file arrivals.
Basic Pipeline Example: Copy a Test data file (.txt) in Azure Blob Storage (Source & Sink (target/destination))
Outline of very high-level steps, we can have a detailed explanation of it in a separate post.
Create Linked Services: Define connections for your source (Azure Blob Storage) and sink (Azure Blob Storage).
Create Datasets: Define datasets that point to your source files and target.
Build a Pipeline: Add a Copy Activity that moves data from the source dataset to the sink dataset.
Add a Trigger: Schedule the pipeline to run manually once or daily to keep your target updated with new data files.
This simple setup can be extended to include data transformations, error handling, and notifications, showcasing ADF’s automation capabilities.
