I’m self hosting a lot of small apps that require databases to function. So far, each stack has its own database, but I’m wondering if it would be better to centralise the data into one single database instance
All the apps are low traffic (it’s just me), and security concerns are minimal (no sensitive data)
Does anyone have any advice on this?

I use one per container that requires one (containers are all about isolation after all) , but since I use Ansible to maintain my Docker hosts, management is really simple.
