Operating Systems are not always set up in the same way. Storage mount points in a system might be larger or smaller, local or remote, with high or low latency, and various speeds. Starting with OneAgent version 1.199, the runtime folder is configurable and consequently you can retain your storage mount point setup as-is.

Perhaps inspired by serverless in spirit and in terminology, the path forward proposed in this paper is towards a managed and model-less inference serving system. Managed here means that the system automates resource provisioning for models to match a set of SLO constraints (cf. autoscaling). Model-less is more confusing.
