Creating Databases for Each Client in a Multi-Tenant System

Asked by TechExplorer92
Hey everyone! I'm diving into multi-tenant systems and I'm curious about how to handle database creation when a new client signs up. If I want to have one database for each tenant, what's the best practice for creating these databases? Is it common to run some commands (maybe using a lambda function) to create a new database and migrate it right after user signup? Any tips or common patterns would be super helpful!

It really depends on how many clients you have. If it's just a few high-value clients, creating dedicated AWS accounts for each might be a good move for better isolation. If youโ€™re looking at around 500 clients, most of whom won't exceed 1GB of data a year, it might be worth considering multiple databases, but that can get a bit complex. Just keeping that in mind!

CloudNinja23: I'm thinking about that too! I haven't even started my MVP yet, but establishing multiple databases upfront seems like a solid strategy.
