Which metrics are used to evaluate Cloud onRamp effectiveness after a SaaS cutover?

• A. Monitor SaaS latency, jitter, and packet loss.
• B. Track only the latency to the SaaS service.
• C. Track only the jitter to the SaaS service.
• D. Track only the packet loss to the SaaS service.

Answer: (B)

End-to-end latency to the SaaS service is the primary measure when evaluating Cloud onRamp effectiveness after a SaaS cutover. The user experience of SaaS apps hinges on how quickly requests reach the provider and how fast responses return, so latency directly reflects this end-to-end delay. Jitter describes variation in delay, and while it can matter for real-time apps, most SaaS web applications tolerate some fluctuation because TCP retransmission and buffering help smooth speeds. Packet loss can degrade performance, but if latency stays low, the impact is less immediate on perceived speed; if losses spike, latency tends to rise due to retries. Focusing on latency gives the clearest, most direct signal of whether the onRamp is delivering faster access to the SaaS service. Other metrics can be useful, but latency is the best single metric in this scenario.
