+# Operator Nexus management upgrades
+
+Operator Nexus releases various functionality and bug fixes throughout the month to update the Azure resources and on-premises extensions, critical in communications back to Azure. 
+
+## Scope
+
+The releases update components on the Cluster Manager and Network Fabric Controller to enable new functionality, while maintaining backwards compatibility for the customer. Additionally, new runtime releases make available and accessed via [Cluster Runtime Upgrades](./howto-cluster-runtime-upgrade.md) and [Network Fabric Upgrades](./howto-upgrade-nexus-fabric.md).
+
+For Compute management, Microsoft delivers new software to the extensions and agents that exist on the platform to provide new functionality and maintain security and communication back to Azure.
+
+## Impact to customer workloads
+
+The intent of these releases is no disruption to running workloads and on-premises resources retain availability throughout the upgrade. Therefore, the customer should see no impact. 
+
+## Duration of on-premises updates
+
+These updates take up to one hour to complete per cluster.
