Web Services: Quota Enablement
Quota enforcement for apps using the web services API

A file with a list of subtenants/UIDs is distributed across all Atmos nodes
– Each Atmos WS node evaluates requests against a restricted file (overquota.txt or readonly.txt) and enforces the appropriate restriction – Web services must be restarted each time a new list is provided to ensure enforcement

Subtenants or UIDs requesting restricted access receive error code response
