A bare metal server corresponds conceptually to the well-known dedicated server. It uses the single-tenancy architecture, is offered by a hostingprovider 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
thehardware of a functioning server. The bare-metal refers to the fact that the server is offered without software. It has no 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. In addition, there is 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 top of the hardware. Applications run on virtual guest systems.memory are shared. In modern IT concepts, dedicated servers are operated in the data centers of hosting providers, where they form the private cloud of a company in cloud computing
. Bare metal servers can be used as web servers.
They are especially interesting for large websites with a lot of content and traffic. They can also work as database servers, where large amounts of data need to be stored and processed, or in the field of computer games.
