We are excited to announce the preview for Data Management Gateway - High Availability and Scalability.

You can now associate multiple on-premise machines to a single logical gateway. The benefits are:

Higher availability of Data Management Gateway (DMG) – DMG will no longer be the single point of failure in your Big Data solution or cloud data integration with Azure Data Factory, ensuring continuity with up to 4 nodes.

Improved performance and throughput during data movement between on-premises and cloud data stores. Get more information on performance comparisons.
