Same job, different isolation
A dedicated server is an entire physical machine: all cores, all RAM, all disk I/O are yours. A VPS is a virtualized slice of one, sharing hardware with neighbors. Dedicated wins on raw and consistent performance; VPS wins on price and flexibility — you can resize a VPS in minutes.
The price gap in practice
Entry VPS plans run USD 4-10/month; entry dedicated machines start around USD 40-80/month and climb fast. Between them sits a large gray zone where people overpay: a workload that fits a USD 6 VPS running on a USD 60 dedicated box, or a bursty app on a VPS that throttles under load.
Noisy-neighbor effects on cheap VPS plans are real but overstated for web workloads; for latency-critical or disk-heavy workloads (databases, game servers), dedicated hardware still earns its price.
The option both comparisons skip
If your workload is a website or API, the honest third option is not renting a machine at all: request-based architectures (static, serverless, hybrid) price by usage and drop to near zero when idle. The machine-versus-machine debate only applies once you have decided you need a machine.
Where SimDeploy fits
SimDeploy's cost engine compares architectures — static, hybrid, serverless, node-server — against real provider price tables for your specific project, before you deploy. Projects that genuinely need a persistent server are routed (and priced) as such; the rest stop paying for idle capacity.
FAQ
Is a dedicated server faster than a VPS?
For consistent, hardware-bound workloads, yes — no neighbors, full disk I/O. For typical web traffic, a well-sized VPS or a request-based platform is indistinguishable to users.
