The article assumes there are people who want clusters. But a single Linux VM in the cloud can scale pretty far. Separate VM's for different apps works well for isolation. Why do I need a cluster?
Wouldn’t it be cheaper / less complex to scale vertically (eg a large workstation or medium size bare metal server) instead of using clusters? My understanding is that clusters are primarily useful when you want to share a resource from a pool across unpredictable usage, which becomes a moot point once the cluster is personal.
