Is this an alternative to Keycloak? One thing Keycloak supports is the ability to create multiple realms in order to use one instance for different groups of users and applications. Does Kratos support something like that?
I do run Keycloak in a container but I'm pretty sure spinning up a new instance for every realm would be more resource intensive than using multiple realms in the same instance.
It's just a question of use case at the end of the day. In my use case I only need this for small internal tools so it's easier to just spin up one instance for me.
