Cloud Services Platform is a generic term and not a specific Cisco SD-WAN feature for regionalized service-chaining.

VNF Service Chaining is a general concept for chaining Virtual Network Functions, but 'Cloud onRamp for Colocation' is the specific Cisco SD-WAN implementation that provides this capability in a regionalized manner.

Cisco SD-WAN Cloud onRamp for Colocation specifically enables regionalized service-chaining by allowing organizations to deploy network functions (like firewalls) in colocation data centers or regional hubs. It then intelligently steers branch traffic to these services, optimizing cost through centralization and improving user experience by directing traffic to the closest or most appropriate service instance based on application-aware policies.

Cloud onRamp for IaaS (Infrastructure as a Service) focuses on connecting SD-WAN to public cloud providers like AWS or Azure, not specifically for regionalized service-chaining of network functions in colocation facilities.
