Azure Batch classic compute node communication model will be retired on 31st March, 2026

Published date: 17 March, 2023

To improve security, simplify the user experience, and enable key future improvements, we will retire the Classic compute node communication model on 31st March, 2026

The simplified compute node communication model will replace the classic compute node communication model after 31st March, 2026. The change will be introduced in two phases. From now until 30th September, 2024, the default node communication mode for newly created Batch pools with virtual networks will remain classic. After 30th September, 2024, the default node communication mode for newly created Batch pools with virtual networks will switch to simplified. After 31st March, 2026, the option to use classic compute node communication mode will no longer be honoured. 

Batch pools without user-specified virtual networks are generally unaffected by this change and the default communication mode will be controlled by the Batch service.

Required action 

Follow these steps to transition using the Simplified compute node communication model before 31st March, 2026.
