Bare Metal Servers

Why would you choose Bare Metal Servers?

Advantages

– BMS are dedicated to a single organization
– Single tenant or dedicated host
– No sharing of hardware, storage, connection, bandwidth (noisy neighbor)
– There is no hypervisor layer
– No virtualization overhead
– OS is loaded straight to the server
– Results in higher performance
– Quality of hardware
– Compliance and security due to single tenant
– Flexible contract, billing options

Disadvantages

– Procurement could take weeks depending on hardware type
– And that goes for replacement hardware as well.
