In SD-WAN SaaS deployments, what is the purpose of a Cloud onRamp?

• A. Redirect SaaS traffic to cloud edge PoPs for optimized path
• B. Provide VPN access to on-prem resources
• C. Act as a DNS resolver for SaaS domains
• D. Serve as firewall at SaaS edge

Answer: (A)

Cloud onRamp in SD-WAN SaaS deployments is about speeding up and stabilizing access to cloud apps by sending SaaS-bound traffic directly to cloud-edge points near the service providers. Instead of backhauling traffic to a central data center, the SD-WAN fabric redirects traffic to cloud onRamp nodes that sit close to the SaaS provider’s edge, enabling a shorter, higher-quality path. This reduces latency, jitter, and potential congestion, and lets policy-based routing and QoS optimize the journey to the SaaS service. The other options describe different functions (VPN to on-prem resources, DNS resolution, or a firewall at the SaaS edge) and are not the purpose of cloud onRamp.
