Private clouds and self-hosted datacenters are making a strong comeback. Unpredictable public cloud costs, data sovereignty requirements, and performance-driven workloads are pushing organizations to bring infrastructure back under their control.
What many teams quickly discover is that the hardest part of this transition is not virtualization nor orchestration, but the physical infrastructure underneath.
Today’s platforms demand cloud-like speed, consistency and automation, either when running workloads directly on physical servers or when provisioning new machines that will host virtual machines or containers. Traditionally, datacenter operating models were not designed for these expectations, and the gap becomes visible as soon as environments scale, or Kubernetes enters the picture.
The return of bare metal in private clouds and datacenters
This whitepaper explores why bare metal is once again central to private cloud strategies, the operational challenges that emerge when it is managed at scale, and how modern platform engineering principles can be applied below the hypervisor.
It also introduces how Canonical MAAS enables bare metal as a service by turning physical infrastructure into an API-driven, lifecycle-managed platform.
Whether you are modernizing an existing datacenter or designing a new private cloud from the ground up, this guide provides a practical framework for operating bare metal safely, efficiently, and at scale.
