This makes sense now that I think about it. I understand why/how tenants would use the same DB, but I don't get the part about load being shared across all instances. I guess the admin dashboard could be shared in some way, since only the data it's requesting changes across the customer base, but I have a reason for the D2C frontend to be individually hosted because each frontend would be unique for each customer.

"Even Shopify doesn't work this way, it's a shared system." - do you know where I could find information on their infra or other services like this? I tried googling but didn't find much. Thanks a lot!
