- Dec 16, 2025 Automatic Rollback Controllers and the Ways They Misfire A controller that reverts a deployment on a metric threshold is a feedback loop wrapped around a feedback loop; its failure modes are oscillation, latency in the evidence, and disagreement about what baseline means. inference systems
- Apr 7, 2025 Level-Triggered Reconciliation: Comparing State Instead of Consuming Events Why a controller that reacts to change events loses convergence after a missed event, how periodic full comparison restores it, and what the comparison costs at scale. distributed systems
- Jan 16, 2024 Level-Triggered Reconciliation and the Desired-State Loop How a platform controller converges observed state toward declared state, why it re-reads everything on every pass, and what that costs in API traffic and correctness. devops
- Aug 20, 2023 Autoscaling Model Servers on Queue Depth Rather Than Utilization Utilization-based autoscaling assumes work is interruptible and cheap to queue; for inference it produces oscillation, so the control signal has to be the wait time a request would experience. inference systems
- Apr 21, 2023 Autoscaling Policies and the Cost of Headroom How a scaling policy converts a load signal into an instance count, why the control loop lags the load, and what each unit of headroom costs per month. cloud infrastructure
