For what does ACI provide a single point of support?

ACI provides a single point of management through the Application Policy Infrastructure Controller (APIC), which centralizes policy definition, deployment, and administration across the entire ACI fabric, replacing the need to configure individual network devices separately.

Visibility is a benefit derived from ACI's telemetry and monitoring capabilities, but it is an outcome of the architecture rather than the singular unified function ACI provides as a management platform.

Orchestration describes how ACI integrates with external platforms such as VMware vCenter or OpenStack, but it is not the native single-point function that ACI itself is designed to fulfill.

Automation is enabled through ACI's REST APIs and programmability features, but it characterizes how operators interact with ACI rather than what ACI consolidates as its core support function.
