Up to marci

What is the difference between "centralizing the logic" and syncing the data to a centralized place?

We can't just move the data to one place. So we would need to centralize the data AND keep it in sync with the rest of the app. This is painful


Logic can be moved to a central place and called upon with an API

What does Oso do to solve authz in microservices?

Local authorization. You can keep your data in the database and Oso can use that data without you centralizing it
