Why Linux Dedicated Servers Are the Backbone of Bare Metal Server Hosting

Modern businesses require hosting solutions that deliver exceptional performance, robust security, and complete control over their infrastructure. As applications continue to require more resources and processing of data becomes more demanding over time, shared hosting services don’t meet the requirements of an enterprise-level business.  

While hosting on Linux dedicated server has become the standard in high-performance hosting, the image of dedicated use combined with the open-source benefit has brought about real solutions exclusively tied to bare metal server hosting in an environment delivering raw performance without the cost of the virtualization overhead. This powerful combination has become imperative for organizations running AI workloads, large data processing, and other performance-dependent applications that require the most reliability and speed possible while giving the organization full control over their infrastructure.

What Is a Linux Dedicated Server?

A dedicated server is a physical server that is assigned exclusively to an individual client, who has total control over all hardware resources (CPU, RAM, disk, and network). Dedicated servers deliver consistent performance over shared hosting environments. Users sharing resources in a shared environment have to compete for resources which makes performance unpredictable.

Dedicated servers predominantly run on Linux due to its open-source nature, stability, and unlimited customization. There are no software licensing costs associated with Linux because it is an open-source platform. And, transparency that allows administrators to modify any component, while optimizing performance to match requirements.

The advantages of dedicated servers running on Linux include greater resource utilization, better security, ample hardware compatibility, and compatibility with nearly all server applications. Linux systems can also continually operate for months at a time without restarting, which is beneficial for mission-critical applications that require maximum reliability and uptime.

Understanding Bare Metal Server Hosting

Bare metal server hosting offers actual physical server hardware with no virtualization layers. Cloud and VPS environments run many virtual machines on shared hardware that use hypervisors to allocate resources; everyone shares the same hardware where the VPS contains a hypervisor. Bare metal hosting uses entire physical servers to deliver resources to one client/server. Because bare metal uses single-tenant architecture, all the server resources are only available to that one client, eliminating resource contention issues, and providing predictable and consistent performance. Bare metal servers dedicate 100% of processing power to client applications, without hypervisor overhead. Bare metal improves response time and increases throughput.

There are also security benefits to bare metal servers. Sole tenant remediates attack vectors associated with shared virtualization platforms. The organization can apply hardware-level security and maintain control of the security stack, which is a useful benefit if the organization is trying to protect sensitive data, or for organizations in regulated industries requiring compliance controls.
