I did something last week that I had not done for a while. I recommended a bare-metal cloud service to a client. They had a particular purpose, and it was the right technology to solve the problem.
In a typical public cloud environment, most users interact with virtual machines, which are operating system instances running on top of physical hardware. These VMs are separated from one another through a hypervisor, which allows multiple users to share the same hardware securely and efficiently. However, this abstraction introduces performance overhead and limits user control over the server’s physical resources.
Bare-metal cloud services, by contrast, provide users with exclusive access to the underlying physical server hardware: no hypervisor, no virtual machines, no additional abstraction. This purity means full access to raw compute power, such as CPU, GPU, and memory resources, without virtualization’s added latency or restrictions. In essence, bare-metal clouds bridge the gap between the flexibility of cloud computing and the robust performance of dedicated on-premises servers.
