 The Azure VM size for your nodes defines CPUs, memory, size, and the storage type available (such as high-performance SSD or regular HDD). Plan the node size around whether your applications may require large amounts of CPU and memory or high-performance storage. Scale out the number of nodes in your AKS cluster to meet demand. For more information on scaling, see [Scaling options for applications in AKS](/concepts-scale.md).

 For managed disks, the default disk size and performance will be assigned according to the selected VM SKU and vCPU count. For more information, see [Default OS disk sizing](cluster-configuration.md#default-os-disk-sizing).
