Both Azure Data Factory and AWS Glue are powerful serverless data integration platforms, but each excels within its respective cloud ecosystem. The right choice depends primarily on your existing cloud infrastructure, team expertise, and specific integration requirements rather than raw feature superiority.
Choose Azure Data Factory if:
Choose Azure Data Factory if your organization operates primarily within the Microsoft Azure ecosystem or requires hybrid cloud connectivity through the self-hosted Integration Runtime. ADF excels for teams that prefer visual, low-code pipeline development with its drag-and-drop designer and 100+ built-in connectors. It is also the stronger choice for enterprises migrating existing SSIS packages to the cloud, as it provides dedicated SSIS Integration Runtime support. Organizations that need tight integration with Microsoft Purview for data governance and lineage tracking will find ADF offers a more unified experience across the Azure data platform.
Choose AWS Glue if:
Choose AWS Glue if your data infrastructure is built on AWS services like S3, Redshift, and Athena. Glue's built-in Data Catalog serves as a centralized metadata store that other AWS analytics services consume natively, creating a seamless analytics workflow. It is particularly well-suited for teams with strong Apache Spark or Python skills who prefer code-first ETL development with Interactive Sessions and notebook support. AWS Glue also provides unique capabilities like FindMatches ML-based deduplication, DataBrew for no-code data preparation, and the Flex execution class that can reduce costs by up to 34% for non-time-sensitive workloads.
This verdict is based on general use cases. Your specific requirements, existing tech stack, and team expertise should guide your final decision.
Azure Data Factory charges $1.00 per 1,000 activity runs for orchestration, with separate per-DIU-hour rates for data movement and per-vCore-hour rates for Mapping Data Flows. AWS Glue charges $0.44 per DPU-hour for standard Spark ETL jobs, with the Flex execution class available at approximately $0.29 per DPU-hour for non-urgent workloads. For a mid-size workload running 6 DPUs for 15 minutes, AWS Glue costs roughly $0.66 per run. ADF pricing varies more by component since each activity type has its own rate structure. Both platforms scale costs linearly with usage, and neither charges when pipelines are idle. The total cost difference depends heavily on job complexity, data volume, and execution frequency rather than the base pricing alone.
Both platforms support near-real-time data processing through micro-batch patterns rather than true row-by-row streaming. Azure Data Factory handles streaming through Mapping Data Flows with tumbling window triggers that process incoming data in configurable time intervals, integrating with Azure Event Hubs and IoT Hub as streaming sources. AWS Glue offers dedicated streaming ETL jobs that consume data continuously from Amazon Kinesis Data Streams and Apache Kafka topics with configurable checkpoint intervals. For true sub-second latency requirements, both providers recommend their dedicated streaming services instead, such as Azure Stream Analytics or Amazon Kinesis Data Analytics. AWS Glue streaming jobs cost the standard $0.44 per DPU-hour while running continuously, making long-running streaming workloads a significant cost consideration.
AWS Glue has a significant built-in advantage with its native Data Catalog, which stores table definitions, schemas, and partition information at no cost for the first million objects stored and first million accesses per month. The Data Catalog serves as a central Hive-compatible metastore that Amazon Athena, EMR, and Redshift Spectrum can query directly. Azure Data Factory relies on Microsoft Purview (a separate service with its own capacity-based pricing) for comprehensive data cataloging, classification, and lineage tracking. Purview provides broader governance features including sensitivity labeling and data estate scanning across multi-cloud environments, but requires a separate deployment and additional costs. For teams needing an integrated catalog without extra setup, AWS Glue's built-in approach is more convenient and cost-effective.
Azure Data Factory offers stronger hybrid connectivity through its self-hosted Integration Runtime, a lightweight agent that installs on-premises or on any VM to securely move data from behind corporate firewalls without opening inbound ports. The self-hosted IR is free for up to 5 nodes and supports sources like SQL Server, Oracle, SAP HANA, and local file systems. AWS Glue connects to on-premises data sources through AWS Direct Connect or VPN tunnels using JDBC connection objects, which requires networking infrastructure setup rather than a simple agent installation. For multi-cloud scenarios, ADF's 100+ connectors include native support for AWS S3, Google Cloud Storage, and other non-Azure platforms. AWS Glue primarily targets AWS-native sources, though JDBC and custom connectors extend its reach. Organizations with significant on-premises data estates will generally find ADF's approach more straightforward to deploy and manage.
