Which Cloud OnRamp solution is used by partners and vendors without Cisco SD-WAN but still need connectivity to their customers without installing SD-WAN routing appliances on their sites?

Cloud OnRamp for IaaS (Infrastructure as a Service) is used to extend the SD-WAN fabric into public cloud environments like AWS or Azure, typically by deploying virtual SD-WAN routers within the IaaS.

Cloud OnRamp for Multicloud is a broader solution that encompasses managing connectivity across multiple public cloud providers, often leveraging IaaS integrations.

Cloud OnRamp for Colocation provides a way for non-SD-WAN partners or vendors to connect to SD-WAN customers through a shared SD-WAN gateway in a colocation facility. This eliminates the need for the partner/vendor to deploy their own SD-WAN edge devices, simplifying connectivity.

Cloud OnRamp for SaaS (Software as a Service) focuses on optimizing connectivity and performance to specific SaaS applications (e.g., Office 365, Salesforce) from SD-WAN branches.
