The Mobile Apps team has been working on an experimental content service (see also T87824). The development and testing phase will soon be over, so the next step would be deployment on the SCA cluster.
The idea is for RESTBase to serve a proxy/storage for it, so a public access point is not needed. We would, however, need an internal IP (so RB can connect to it). As far as configuration/puppetisation goes, the service uses service-template-node and thus shares important bits and pieces with other, already in production, services, such as RESTBase, Parsoid, Citoid. Hence, not much work is anticipated on this front.
