Azure Kubernetes Service (AKS) now includes several control plane enhancements to enable large clusters scale more efficiently and operate reliably. These enhancements include streaming LIST responses, higher control plane resource limits, API server guard and etcd defragmentation optimizations.
As engineering teams seek to optimize costs and maintain scalability in the cloud, leveraging Azure Spot Virtual Machines (VMs) in Azure Kubernetes Service (AKS) can help dramatically reduce compute costs for workloads tolerant of interruption.
However, operationalizing spot nodes safely—especially for production or critical workloads—requires deliberate strategies around cluster autoscaling and workload placement.
