Top Reasons WHY TO & WHY NOT TO run Docker containers on Bare Metal System

Why to run containers on Bare Metal System?

Containers on bare-metal hosts get many of the advantages VMs offer but without the drawbacks of virtualization:

In addition, by hosting containers on bare metal, you get the benefits that have traditionally been possible only with VMs:

In short, run containers on bare metal to square the circle – do what seems impossible. Reap all the benefits of bare-metal servers’ performance and hardware accessibility, and take advantage of the portability and isolation features seen with VMs.


You probably are wondering why we don’t run all containers on bare metal. Consider the following drawbacks of using bare-metal servers to host a container engine, rather than VMs:

Here’s a Bonus..

Linux containers on bare-metal Windows

Historically, there was not an easy, efficient way to run Linux containers on a Windows host. However, Linux Containers on Windows (LCOW) is a tool from Docker that automatically runs Linux containers on a Windows host.

Technically, LCOW needs the Windows host to set up a Hyper-V hypervisor, so the Linux containers actually don’t run directly on bare metal inside the Windows environment. However, the hypervisor footprint is miniscule, and the hypervisor is fully managed. Consequently, the performance and management drawbacks associated with hosting containers inside a VM don’t exist with LCOW, and the technology removes another historical downside of running containers on bare metal.
