SLO-Based Rollback
SLO-Based Rollback governs automatic rollback on budget breach, shaping system behavior under specific failure modes and workloads.
Definition
SLO-Based Rollback is a design property concerning automatic rollback on budget breach. It defines how the system behaves under specific conditions — what guarantees hold, what trade-offs apply, and how the mechanism interacts with related techniques. The property is only meaningful when its preconditions are met; outside those conditions it provides no benefit and may add cost.
Context and scope
Apply SLO-Based Rollback when designing systems where automatic rollback on budget breach matters. It is most useful under partial failure, high load, or correctness requirements. Pair it with observability to verify the claimed behavior in production. Do not assume the property holds without testing the specific configuration and workload.
Common misconceptions
- SLO-Based Rollback eliminates all problems in its domain — it only bounds or shapes specific failure modes, not all pathologies.
- SLO-Based Rollback is free once you adopt the right tool — the property depends on configuration, workload, and failure pattern, not the product label alone.
Anti-patterns
- Enabling SLO-Based Rollback without measuring its cost in latency, availability, or operational complexity under production-like conditions.
- Assuming SLO-Based Rollback composes safely with other guarantees — combining mechanisms can introduce new failure modes or negate benefits.
