Azure Data Factory (ADF) serves as the primary orchestration service for data integration. It enables you to create data-driven workflows for moving and transforming data at scale. ADF supports over 90 built-in connectors, allowing seamless connections between on-premises and cloud data sources. It excels at ETL (Extract, Transform, Load) and ELT operations, making it ideal for data warehouse population and batch processing scenarios.
For real-time data integration, Azure Event Hubs and Azure Stream Analytics provide powerful streaming capabilities. Event Hubs can ingest millions of events per second, while Stream Analytics processes and analyzes streaming data using SQL-like queries. This combination suits IoT scenarios, live dashboards, and real-time analytics requirements.
Azure Synapse Analytics offers an integrated approach by combining data integration, enterprise data warehousing, and big data analytics. Its Synapse Pipelines feature, built on ADF technology, enables data movement and transformation within the same analytical workspace, reducing complexity and improving developer productivity.
For hybrid integration scenarios involving applications and APIs, Azure Logic Apps and Azure API Management provide low-code solutions. Logic Apps connects SaaS applications and enterprise systems through pre-built connectors, while API Management secures and manages API traffic.
When recommending a solution, consider factors such as data volume, velocity, variety, latency requirements, existing infrastructure, and team expertise. For complex enterprise scenarios, a combination of these services often provides the most comprehensive solution. Cost optimization, security compliance, monitoring capabilities, and disaster recovery requirements should also influence your architectural decisions. Proper data governance through Azure Purview ensures data quality and lineage tracking across all integration points.

Why Data Integration is Important
Data integration is a critical component of modern cloud architectures because organizations often have data scattered across multiple sources, formats, and locations. Effective data integration enables businesses to:
• Make informed decisions based on unified data views • Automate data workflows and reduce manual processing • Enable real-time analytics and reporting • Maintain data consistency across systems • Support hybrid and multi-cloud scenarios
What is Data Integration?
Data integration refers to the process of combining data from different sources into a meaningful and unified view. In Azure, this involves moving, transforming, and consolidating data from various on-premises and cloud-based systems into a centralized location or making it accessible across platforms.
Key Azure Data Integration Services
Azure Data Factory (ADF) The primary orchestration service for data integration in Azure. It provides: • 90+ built-in connectors for various data sources • Code-free ETL/ELT pipelines • Data flow transformations • Scheduling and monitoring capabilities • Integration runtime for hybrid scenarios
Azure Synapse Analytics Pipelines Similar to Data Factory but integrated within Synapse workspace. Best for scenarios where you need tight integration with Synapse Analytics for big data processing.
Azure Logic Apps Ideal for event-driven, lightweight integrations and workflow automation with SaaS applications.
Azure Event Hubs For real-time streaming data ingestion from multiple sources at scale.
Azure Stream Analytics For real-time data processing and analytics on streaming data.
How Data Integration Works in Azure
1. Connect: Establish connections to source systems using linked services and integration runtimes 2. Ingest: Move data from sources to Azure using copy activities or streaming ingestion 3. Transform: Apply data transformations using mapping data flows, Spark, or SQL 4. Orchestrate: Create pipelines that coordinate and schedule data movement activities 5. Monitor: Track pipeline runs, set up alerts, and manage data lineage
Integration Runtime Types
• Azure Integration Runtime: For cloud-to-cloud data movement • Self-hosted Integration Runtime: For on-premises or private network data sources • Azure-SSIS Integration Runtime: For lifting and shifting existing SSIS packages
How to Answer Exam Questions
When facing data integration questions on the AZ-305 exam, follow this approach:
1. Identify the data source types: On-premises, cloud, SaaS applications, or streaming 2. Determine latency requirements: Batch processing vs. real-time streaming 3. Consider data volume: Small datasets may use simpler solutions; large-scale requires robust services 4. Evaluate transformation complexity: Simple copy vs. complex ETL logic 5. Check for existing investments: Legacy SSIS packages suggest Azure-SSIS IR
Exam Tips: Answering Questions on Data Integration
Tip 1: If the scenario mentions moving data from on-premises databases to Azure, look for answers involving Self-hosted Integration Runtime with Azure Data Factory.
Tip 2: When real-time or streaming data is mentioned, consider Azure Event Hubs combined with Azure Stream Analytics.
Tip 3: For scenarios requiring both data integration and big data analytics in one solution, Azure Synapse Analytics is often the preferred answer.
Tip 4: Questions mentioning existing SSIS packages should point you toward Azure-SSIS Integration Runtime.
Tip 5: If the scenario involves simple SaaS-to-SaaS integrations with minimal data transformation, Azure Logic Apps may be the correct choice.
Tip 6: Always consider cost and complexity. The exam often tests whether you can select the most appropriate and cost-effective solution rather than the most feature-rich one.
Tip 7: Pay attention to keywords like 'orchestrate,' 'schedule,' and 'pipeline' which typically indicate Azure Data Factory.
Tip 8: Remember that Azure Data Factory supports both ETL (Extract, Transform, Load) and ELT (Extract, Load, Transform) patterns depending on where transformations occur.
