CPU Isolation Boundary

CPU Isolation Boundary is a compute security boundary that separates workloads so one cannot affect another unexpectedly for general-purpose processor scheduling. It uses namespaces, sandboxes, and access controls so teams can reduce cross-workload risk while keeping evidence, reliability, and public-safe operational boundaries clear.

“The platform engineering team used CPU Isolation Boundary when the service hit a compute ceiling, so the team could reduce cross-workload risk before the workload scaled up.”
