What is Azure Kubernetes Fleet Manager?
Azure Kubernetes Fleet Manager (Fleet) enables at-scale management of multiple Azure Kubernetes Service (AKS) clusters. Fleet supports the following scenarios:
Create a Fleet resource and group AKS clusters as member clusters.
Orchestrate Kubernetes version and node image upgrades across multiple clusters by using update runs, stages, and groups.
Create Kubernetes resource objects on the Fleet resource's hub cluster and control their propagation to member clusters (preview).
Export and import services between member clusters, and load balance incoming L4 traffic across service endpoints on multiple clusters (preview).
