Yes, I’ve been searching it extensively.
I founds results like: Best practice for Trellis with multiple sites however there question while at first glance looked similiar was about having sites that would all be subdomains and he was more asking if it was possible rather than which option is recommended.
And also saw Trellis setup for multiple Bedrock instances in subfolders but was also about havnig one domain with sub directories rather than completely seperate sites.
But if there is another thread where someone asked the recommended structure for multiple seperate sites and addresses the potential hard drive space issue of so many virtual servers, do let me know and I’ll take a look! I’ll keep searching in the meantime as well.
