The decision to migrate latency-sensitive workloads to the cloud has made the issue of whether to use public internet-based transit or direct interconnects a key architectural choice. In this paper, an empirical performance comparison has been described between traditional Public Internet (with IPsec VPN) and Private Direct Connect (AWS Direct Connect) to measure the reliability and speed trade-offs. We evaluated throughput, Round-Trip Time (RTT), and packet loss with a sustained 14-day cycle in a distributed experimental infrastructure in two large metropolitan areas. As our experimental results show, although the public internet has adequate bandwidth to support an asynchronous workload, it exhibits considerable micro-burst latency peaks, and jitter values reach as high as 35ms during periods of extreme congestion. Conversely, the Private Direct Connect continued to record sub-5ms jitter variance and a 22-percent greater sustained goodput on large-scale database synchronisation. In addition, we examine the effects of protocol overhead and show that the encryption layer of public VPNs decreases effective payload capacity by nearly 8%. Such results provide a strict, data-driven benchmark against which enterprise architects can measure the cost-performance ratio of dedicated cloud circuits, in the case of real-time analytics and high-frequency financial applications.
