Operator Nexus Cluster Management Bundle Upgrades

Operator Nexus releases various functionality and bug fixes throughout the product lifecycle to update the Azure resources and on-premises extensions, critical in communications back to Azure.

Note

This article describes Cluster Management Bundle Upgrades (CMBU), which are non-disruptive and automatically applied by Microsoft. These upgrades are separate from Cluster Runtime Upgrades, which are customer-managed and disruptive. For more information, see Related content.

Scope

The releases update components on the Cluster to enable new functionality, while maintaining backwards compatibility for the customer. Additionally, new runtime releases are made available and accessed via Cluster Runtime Upgrades.

Delivery

CMBU is triggered independently when the release is available in the Azure region.

Impact to customer workloads

There's no disruption to running workloads or instantiating new workloads, and on-premises resources retain availability throughout the upgrade. Therefore, the customer sees no impact.

Duration of on-premises updates

Updates take up to one hour to complete per Cluster.

Azure Operator Nexus includes multiple upgrade types that serve different purposes.

Network Fabric Management upgrades (non-disruptive)

Runtime upgrades (customer-managed, disruptive)
