Centralized vs. Distributed Authorization: The CAP Theorem
One of the best parts of working on the Open Policy Agent at Styra is that we get to help people design authorization systems for both their platform and their custom applications. The other day we were talking someone through the design tradeoffs of authorization for their application, and the first decision they had to make was whether they wanted a centralized authorization system or a distributed authorization system. Both OPA and Styra support either, so we have no real bias.
