What Are the Main Differences Between Cloud Servers and Dedicated Physical Hosting?

All answers to this question.

For high-frequency trading, bare metal usually wins because of the zero-latency overhead of a hypervisor. Cloud servers use virtualization, which introduces a small layer of delay. However, modern "Compute Optimized" instances in the cloud use SR-IOV and dedicated CPU pinning to mitigate the noisy neighbor effect. You get the benefit of scaling up instances in minutes during peak market volatility, which is something you simply cannot do with physical hardware sitting in a rack.

Are you planning to use a specific region for your deployment to minimize the physical distance to the exchange, or are you prioritizing raw compute speed over network hop latency?

• David, for our use case, the network hop is critical, but the jitter caused by CPU steal time in a virtualized cloud server is what really kills our margins. We are looking at AWS Outposts or specialized low-latency zones. If the cloud provider can guarantee dedicated hardware threads, we might consider the move, otherwise, we stay on-prem with our own dedicated physical boxes for the core execution engine.

Dedicated servers are great for steady workloads, but if your traffic is unpredictable, the cloud’s ability to auto-scale will save you much more in the long run.

• Barbara is spot on. For the majority of web apps, the "performance hit" of a cloud server is negligible compared to the massive operational agility and disaster recovery features you gain.
