To avoid performance issues, Pachyderm recommends that you set this value to at least `Standard_DS4_v2` which gives you 8 CPUs, 28 Gib of Memory, 56 Gib SSD. AKS allows us to automate the creation of the worker nodes. Additionally, the performance of the P4 disks (120 IOPS / 25 MB/s throughput) as OS disks is the real pain here and slows down the spin-up of the containers during the upgrade process. So if you want to increase the size, you have to use Azure CLI to create your AKS. --node-osdisk-size. Azure defaults the OS disk to 30GB, but if you look at the Managed Disk Pricing, the minimum size you are charged for is 32GB. Creating and configuring a Cluster; Upgrading a cluster.
