What are bare metal servers? Are they the right decision for all customers? What benefits can they bring? Here's an attempt to answer these questions

Bare metal servers offer a variety of benefits to users - there's little latency, better availability of resources, and root access for tenants. All of these factors often lead to an improvement in overall performance. Another advantage that a lot of users talk about is that bare metal servers are highly customizable.

But, what are bare metal servers? Are they the right decision for customers of all types? What specific advantages can they bring to environments? Here's an attempt to answer all these questions and give an overview of the topic.

What is Bare Metal?

A bare-metal server is a physical computer server that is dedicated to a single tenant. It comes without the additional virtualization/hypervisor layer that is typical in a cloud-based infrastructure. In bare-metal environments, even though the user rents the server from a provider, every decision regarding how the server can be used lies with the renter, including the OS. The term 'bare metal' is used to distinguish between servers that utilize virtualization and cloud hosting and often run multiple tenants in a single environment.

As mentioned, bare metal servers are used by a single tenant and are not shared between customers. The user can determine to run any amount of work or have multiple users within the environment if they choose to do so. Unlike servers in a public cloud environment, the server resources are not being shared between multiple customers. The physical separation makes bare metal servers avoid the “noisy neighbor” effect that's often seen as a problem with some virtual environments. They are ideal for customers who need maximum flexibility and minimum interference from providers.

Major Benefits of Bare Metal

We've covered some of the advantages of bare metal servers already, but here is a slightly more detailed glance at them.

Complete Control of Underlying Infrastructure: The tenant gets full control over the hardware. This control will come in handy when setting up firewall protocols, integrating network and storage, and other unique requirements.

Dedicated Resources: Since there is no hypervisor for virtualization in bare metal, the environment has no overhead, and the servers offer high-performance computing. All the hardware compute power and resources are dedicated to the tenant applications.

Customizability: The physical server system can be used to create applications the way the tenant wants to. Customization can be made in anything from storage to RAM to GPUs.

Cost-Effectiveness: As bare metal servers are often bundled with bandwidth, cost overages become less of an issue. Moreover, a highly customizable environment means that you use what you need, which avoids resource wastage and additional costs related to that.

Security: The user can integrate their preferred security or encryption protocol into the environment without the provider's interference.
