bare metal server

A bare metal server corresponds conceptually to the well-known dedicated server. It uses single-tenancy architecture, is offered by a hosting provider and can be rented by companies and other users. The resources in terms of computing power, security and reliability are exclusively available to the renting customer.

Bare-metal, which stands for bare metal, refers to the hardware of a functioning server. The bare-metal refers to the fact that the server is offered without software. It does not have a pre-installed operating system or application software. The hosting provider installs the desired operating system and all application programs run under the installed operating system. There is also a bare metal concept with a hypervisor. This server concept knows only one user, who alone can use the full computing power and storage capacity for his application. In this concept, the hypervisor can support multiple operating systems running different application programs. The hypervisor is a native hypervisor that sits directly on the hardware. Applications run on virtual guest systems.

This contrasts with shared hosting with hypervisors, in which the virtual server is available to several users at the same time and the available resources of computing power and memory are shared. In modern IT concepts, dedicated servers are operated in the data centers of hosting providers, where in cloud computing they form the private cloud of a company.

Bare metal servers can be used as web servers. They are especially interesting for extensive websites with a lot of content and traffic. They can also work as database servers, where large amounts of data have to be stored and processed, or in the field of computer games.
