Bare metal (x86)

Pros • Familiar • Performance• Data management

Cons • Static hardware• Slow and expensive provisioning• Low utilization per host

@vpetersson

Virtual machine overview

Pros • Flexible server sizes• Higher host utilization• Simple migration path• Scale with demand2

Cons • “Noisy neighbor” issue• Overhead on host1

• Management1

• Data control2
