Bare Metal: The Infrastructure for Critical Workloads and Maximum Performance

Introduction: when virtualization is no longer enough

With the generalization of public cloud and virtualized environments, it may seem outdated to return to a physical infrastructure. However, in many cases, especially for critical workloads, Bare Metal is the only truly suitable solution.

These are dedicated physical servers, fully allocated to a single company, without a shared hypervisor layer. This architecture guarantees maximum performance, full control of resources, and greater predictability of processing.

Some applications – sensitive databases, heavy processing, real-time services, certified hosting – require an isolated, optimized environment without the vagaries of virtualization. Bare Metal precisely meets these constraints.

This article aims to shed light on the technical and strategic challenges of the Bare Metal model, and to show why it remains a technological reference choice for demanding companies.

Bare Metal: what is it, and who is it for?

A Bare Metal server is a dedicated physical server, installed in a datacenter, which is not shared with any other client. Unlike a VPS server or a shared infrastructure, it offers total exclusivity of CPU, RAM, disk and network resources.

Companies choose Bare Metal when they search :

• Constant performance, without external interference
• Extremely low latency (for real-time processing, e.g.)
• Direct access to the hardware, without an abstraction layer
• A complete customization of the OS, the BIOS, or the network layers
• An infrastructure ready for HDS, ISO or PCI-DSS certification

It’s the ideal solution for critical workloads, high availability cluster deployments, or applications requiring an isolated environment.

Bare Metal thus combines the power of a modern datacenter with the proximity and control of a local server.

Technical advantages: raw power, safety, predictability

The main asset of Bare Metal is the total mastery of performance. Without software overlay or mutualization, companies can calibrate their infrastructure exactly to their needs.

Bare Metal also helps to avoid the effects of "neighborhood noise", often observed on shared cloud platforms.

It is also particularly suitable for DevOps or Kubernetes architectures that require dedicated physical nodes to manage high-density clusters.
