Hello Vlastik, we run a handful DSpace instances at our institution. For every service we have a single instance - independent of number of items. We discussed your solution, too. But decided against, because of following points:
* lesser scabalbility and maintenanability if there come more services or users * all data are in one assetstore unassigend to a service - in case of a serious breakdown it could be very hard to separate the data and move them consistent in an another system (DSpace or something else) For us it is the best way to install and maintain one instance for one service. If there are only less items, your single VM don't need that much power, too. I'm not sure, if you maybe talked to my colleague. But we introduced at OR2019 our DSpace-Clustering (https://www.conftool.net/or2019/index.php?page=browseSessions&form_session=349). Maybe the setup is interesting for you - besides the Puppet configuration. At our institution we run both all components on a single VM and each component on a single VM (Clustering).
