Infrastructure Scaling Model

Infrastructure scaling follows an incremental model where compute and network capacity are added in staged rollout windows. Each expansion window includes baseline validation of latency, packet loss, and node-level contention before customer workloads are redistributed. This staging model avoids abrupt topology changes that can degrade routing performance.

Scaling policy distinguishes between horizontal and vertical pressure. Horizontal pressure appears when aggregate workload density rises beyond node scheduling tolerance. Vertical pressure appears when specific workloads outgrow single-node characteristics such as CPU cache locality or storage queue depth. The platform responds with targeted placement changes rather than broad migration events.

Reliability impact is evaluated through Monitoring Systems and operational SLO indicators documented in Status & Reliability.
