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?
A similar question was here, a few days ago, maybe it helps:
I use just one.
I have multiple services on it (docker containers, custom data tracking) and have not had an issue.
I consistently surprised at how low my memory usage is on one instance 330 mb.
The maintenance of keeping up a db each docker just isn’t worth it or necessary.
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.
