vcluster
vCluster - Create fully functional virtual Kubernetes clusters - Each vcluster runs inside a namespace of the underlying k8s cluster. It's cheaper than creating separate full-blown clusters and it offers better multi-tenancy and isolation than regular namespaces.

InfluxDB
Power Real-Time Data Analytics at Scale. Get real-time insights from all types of time series data with InfluxDB. Ingest, query, and analyze billions of data points in real-time with unbounded cardinality.
I think DaemonSets, and some other things that require node information, can actually be used with the vCluster. You just need to add "--fake-nodes=false" flag, and vcluster will sync node info into your virtual cluster. More info on this topic is in the docs: https://www.vcluster.com/docs/architecture/nodes
