SLO (Service Level Objective)

An SLO is an internal target for service reliability, typically more stringent than customer-facing SLAs.

What is an SLO?

A Service Level Objective (SLO) is an internal target for service reliability, defining the desired level of service measured by SLIs, used for internal reliability engineering.

SLO Principles

User-centric targets, Error budgets, Measurable and achievable, Iteration over time.

Common Misconceptions

"SLO equals 100% availability" - Error budget concept
"SLOs are just for SRE teams" - Organization-wide concern
"SLOs are static" - Evolve with service maturity
