IAM vs SLO
IAM (Identity and Access Management) 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: IAM refers to identity and access management, while SLO refers to service level objective — they describe different things even when they show up in the same sentence.
IAM — Identity and Access Management
The system that controls who is who and what they can touch. The first thing auditors ask for and the first thing attackers attack — get it wrong once and the cleanup is measured in quarters.
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.
