Error budgets balance reliability and velocity by setting measurable SLO targets, allowing you to govern deployment risks based on remaining budget within a rolling time window. This formalizes the tradeoff between releasing changes and maintaining service stability.

An SLO error budget policy maps your current budget status to deployment and toil automation decisions, using SLIs and SLOs over a rolling window like 30 days. It provides policy-driven guidance to decide on releases and changes while managing service reliability.

To guide deployment decisions, define clear SLIs and SLO targets for your services, then establish an error budget over a rolling time window. Applying this policy helps you reason about the tradeoff between reliability and the velocity of change.

Governing reliability requires clearly defined SLIs, SLO targets, and a rolling time window such as 30 days to calculate error budgets. You also need a policy mapping budget status to deployment and toil automation decisions to apply the governance effectively.

SLO error budgets help reduce manual toil by identifying repetitive work as automation targets based on your budget status. This approach maintains service reliability while systematically reducing manual repetitive work through policy-driven decisions.

Use an SLO error budget policy for incident response when you have measurable SLIs and SLO targets over a rolling window. It applies policy-driven guidance to decide on releases and changes, helping balance reliability and velocity during incidents.
