RBAC vs SLO
RBAC (Role Based Access Control) and SLO (Service Level Objective) both come up in technology conversations and get confused. Here's the plain-English difference, side by side, so you can use each one with confidence.
The key difference: RBAC refers to role based access control, while SLO refers to service level objective — they describe different things even when they show up in the same sentence.
RBAC — Role Based Access Control
An access model where permissions attach to roles, not individuals. Scales cleanly until roles explode — then it needs ruthless pruning or it becomes worse than no model at all.
SLO — Service Level Objective
The internal reliability target a team commits to — for example, 99.9% successful checkouts. SLOs sit one level above SLAs and force tradeoff conversations before customers feel the pain.
