We were just moving into AWS secrets when I left. The API was simple enough, other than the fact that now everyone had to use aws login instead of just the few of us working in terraform, and the terribly chosen session timeout, which I don’t know if our people chose or AWS chooses.
But the management of the namespaces/roles for secret visibility looked Stone Age to me. I did not envy the OPs team the problems they were volunteering to deal with.
It feels like the same brand of tedious bookkeeping that led to the Arc security hole.
