Benefits of Using ADF for Hybrid Cloud Data Integration
1) Streamlined Movement of Data
The Azure Data Factory Consulting Services reduces the need for elaborate, custom script generation for the movement of data both ways, i.e., from on-premise to the cloud. It provides pre-built connectors, and in conjunction with a visual interface that executes such transfers much quicker, great savings are made in terms of time and resources.
2) Enabled Data Accessibility and Visibility
ADF centralizes data management; that means it enables common visibility of the same through all organizational data, whatever their place is located. That means an improved perspective where everybody can allow making much better decisions from a full and collective picture of the data.
3) Simplified Data Management
It is the very purpose of ADF to provide one platform from where all of your data integration tasks can be managed. It means there is no need to run after multiple tools for on-premise and cloud data, which in turn means smoother and effective data management experience.
4) Cost Savings
ADF provides a serverless architecture of data integration without provisioning and managing infrastructure. In addition, with a pricing model on a pay-per-use basis, one ends up paying for what they use, hence cutting the cost of data management in general.
Key Features of ADF for Hybrid Cloud Data Integration
1. Extensive Data Source Connectors
ADF boasts a comprehensive library of over 90 built-in connectors to on-premises and cloud-based data sources, supporting the broadest possible data formats of structured, semi-structured, and unstructured data platforms, including relational databases, cloud storage, and SaaS applications.
2. Code-free and Visual Data Flow Design
ADF is codeless and fully visual in designing data flow. By drag-and-drop in a data flow, use fully visual, codeless data sources linking transformation activities to the sinks (destinations) without writing a single line of code. This makes ADF usable by both data engineers and business users who have little experience in coding.
3. Convert Data with Built-In Transformation Capabilities and Functions
ADF provides built-in data transformation capabilities in order to cleanse, manipulate, and enrich the data flow. Custom activities also enable you to perform advanced transformations by using external tools or writing your code.
4. Secured Data Access with RBAC
ADF integrations are seamlessly integrated with Azure Active Directory (AAD) for Role-Based Access Control (RBAC) to ensure that only authenticated users are accessed to manage the data pipelines and hence your data security in a hybrid environment.
5. Monitoring and Scheduling of Automated Workflows
ADF offers rich monitoring with the possibility to monitor what is the status of the data pipeline execution, including possible errors or issues taking place inside the pipeline. A data pipeline can further be scheduled to run after a certain interval on its own or by an event to ensure there is always continuity in the process of data integration.
Building Hybrid Data Pipelines with ADF
Data pipelines in ADF, refers to the workflow for data movement and data transformation. It will have a sequence of activities like below.
- Source: Defines the source data store (e.g., on-premises SQL Server database, Azure Blob Storage).
- Data flow: The nucleus of the pipeline, where data transformation gets applied.
- Sink: Defines the destination for the transformed data (e.g., Azure Synapse Analytics, on-premises data warehouse).
Step-by-Step Guide: Building a Basic Hybrid Data Pipeline with ADF
Following is a very simple example of an ADF data pipeline that simply moves data from an on-premises SQL Server Database to Azure Data Lake Analytics storage.
- Create an ADF Pipeline: In the ADF UI, a new pipeline should be created with a descriptive name (e.g., “OnPremToADLS”).
- Configure Source: Add a “SQL Server” connector as the data source activity. Provide connection detail for the on-premise SQL server database server, database, and credential details.
- Define Data Flow: Drag a Data Flow activity to the pipeline. Here, define how the structure of the data transformation logic is going to be.
- Choose Source Data: In the data flow, choose the already created SQL Server connection as a source. Select the table from which you would want to extract the data.
- Data Transformation (Optional): Wherever required, you may add transformation activities within the data flow. ADF provides a rich set of in-built functions for filtering, joining, aggregation, etc. And if required, you can use a custom activity for a more complex transformation.
- Sink Configuration: Add an “Azure Data Lake Storage Gen2” connector as the sink activity. Provide connection details of your ADLS account and the folder location that you want to extract into the data.
- Schedule or Trigger: Optionally, you may schedule the pipeline to run automatically on a recurring basis (e.g., daily) or else set up a trigger that activates the pipeline upon occurrence of specific events (e.g., new data arrival in the source database).
- Publish and Run: After configuration, the data pipeline should be published in order to make it active. You can then trigger the pipeline manually or monitor it automatically through the ADF interface to check if the pipeline is successfully executing.
ADF has an interface that uses visual designers, whereby users can comfortably develop and configure data flows using a drag-and-drop mechanism for data sources, transformation activities, and sinks to develop visual data pipelines. With that, you don’t have to go through the hassle of writing very complex codes. Therefore, ADF is usable by many.
