PR.IR-04 - Maintaining Resource Capacity for Availability
Show notes
PR.IR-04 maintains sufficient resource capacity—storage, compute, power, and bandwidth—to ensure system availability, monitoring usage and forecasting needs. This proactive scaling prevents performance bottlenecks or failures that could disrupt operations. It aligns capacity planning with risk and resilience objectives.
This subcategory supports uninterrupted access to critical systems by anticipating growth and stress scenarios, ensuring resources meet demand. It reduces availability risks through data-driven adjustments, keeping services operational. PR.IR-04 sustains the infrastructure’s ability to deliver under pressure.
