restarti

Restarti is a term used in computer science and engineering to describe a family of fault-recovery techniques centered on restarting components or services after a failure. The concept emphasizes rapid restoration of service and minimization of human intervention.

Restarti encompasses policies, mechanisms, and tooling that trigger restarts automatically in response to faults, health signals, or configuration changes. It can apply to single processes, microservices, virtual machines, containers, or embedded controllers. The restart can be cold (full reinitialization), warm (redeploying stateful components with preserved memory), or hot (in-place restart with minimal disruption).

The term is used in some engineering communities as a shorthand for restart-based resilience. It draws on watchdog timers, supervision trees, and health checks to determine when to initiate a restart. In practice, restarti is often combined with redundancy, health monitoring, and safe rollback mechanisms to limit data loss and service interruption.

Implementation considerations include determinism and idempotence of restart procedures, safe state handling, and ensuring that repeated restarts do not mask underlying faults. Observability, metrics, and alerting help distinguish transient faults from persistent failures. Configuration of restart thresholds, backoff strategies, and rollout plans is a core part of applying restarti in production.

Variants and related concepts include graceful restarts, rolling restarts, standby pools, and restart policies. Some software frameworks and orchestration platforms implement restarti through managed lifecycles that coordinate health checks and service updates.
