We are pleased to announce improvements to regional subscription limits for Azure SQL Managed Instance. These changes simplify subnet management and provide more granular control over vCore capacity across hardware generations.
What’s changing?
Two changes are now generally available:
Regional subnet limits are removed
Azure SQL Managed Instance no longer applies service-specific regional subnet limits. Instead, deployments are governed by the applicable Azure Resource Manager virtual networking limits.
This simplifies resource planning and removes the need to monitor or request increases for Azure SQL Managed Instance regional subnet limits.
Regional vCore limits are now hardware-generation specific
Regional vCore limits are now managed separately for each supported hardware generation:
• Standard Series
• Premium Series
• Premium Series Memory Optimized
Previously, a single regional vCore limit applied across hardware generations. With hardware-generation-specific limits, customers can request additional capacity only for the hardware generation required by their workloads.
For example, if you need additional Premium Series capacity in a region, you can request an increase for Premium Series without changing the limits for Standard Series or Premium Series Memory Optimized.
What does this mean for existing customers?
Existing regional vCore limits will be automatically converted to hardware-generation-specific limits. No customer action is required.
Your new limits can be viewed and managed through the Azure portal. If the default limit for a hardware generation is insufficient for a planned deployment, you can request an increase for that specific hardware generation.
New hardware generation specific vCore limits apply to both single-zone and multi-zone (Zone Redundant) Managed Instance deployments.
Benefits
These improvements provide:
• Simpler quota management through the removal of service-specific regional subnet limits.
• Better granularity with separate vCore limits for each hardware generation.
• Greater flexibility to request capacity only where it is needed.
• A seamless transition with automatic conversion of existing limits.

We hope these changes make planning and scaling your Azure SQL Managed Instance deployments simpler and more flexible.
