GPlatform Control
The upstream half: the authority GControl instances enrol into.
The service we run. It issues licences, carries the catalogue and the signed artifact store, escrows lockdown keys, drives the support workflow, and manages the cloud deployments. GControl is the half you run; this is the half we do.
GPlatform Control is built and maintained by Gelhaus Solutions. The detail — what it does, how it is built and where it stands — is on their site.
