When to choose bare metal over a VM
WHAT IT TESTS: hardware-level trade-offs. OUTLINE: bare metal suits latency-sensitive or high-throughput workloads needing no hypervisor overhead, single-tenant isolation for compliance, or direct hardware and licensing access.
WHAT IT TESTS: whether you understand when removing the hypervisor is worth losing elasticity. ANSWER OUTLINE: choose bare metal when you need maximum, predictable performance with no virtualization overhead or noisy-neighbor jitter, such as HPC, large databases, or low-latency trading; when single-tenant physical isolation is required for security or compliance; or when the workload needs direct hardware access, specialized accelerators, nested virtualization, or per-socket licensing.
