A bare metal server is an advanced physical server that delivers a specific set of services to one customer.

This article will explain the basics of a bare metal server and how it functions in today's digital world.

What is a Bare Metal Server?

A bare metal server is an advanced physical server that delivers a specific set of services to one customer.

It works in a single-tenant environment, which is stable and reliable because the physical resources of its server are not shared among multiple tenants.

Physical separation between machines prevents them from being connected to other components of the network and eliminates the 'noisy neighbor' effect that is prevalent in virtual ecosystems.

A bare metal server can process large amounts of data and run for long periods, which can increase its overall performance.

Unlike virtualized machines, bare metal servers allow direct access to the hardware architecture.

Here's an example. To access the physical hardware underneath, layers in a typical virtual computer (VM) are stacked one on top of the other.

This means that a guest operating system such as Ubuntu, Windows Server, or Red Hat sits above a hypervisor that sits above the hardware.

The end-user only has access to the guest OS and management interface for provisioning the VM. These architectures do not allow users to connect directly to the hardware. Bare metal servers, on the other hand, allow users to interact directly with physical hardware.

Users have many options when designing their platform, which can openly render service and host an app. As with virtualized systems, which require a minimum of one layer of software, bare metal servers don't need more than one.

With fewer software layers between the user and physical hardware, the server's performance can be improved. It is important to note that tenants of bare metal can create VMs on the hardware just like in a virtualized environment.

Let's take a look at a simple analogy. A bare metal server can be compared to a house that a user owns, in which the user can customize it according to his choices and preferences.

The user can remain isolated from nearby noises and neighbors. Virtualized environments can host multiple tenants. Multiple users can share the resources of the virtual server, such as storage and computing.

This scenario can be compared to renting an apartment in which a neighbor interferes and can disrupt your personal space and life.

Bare metal servers can be a benefit to organizations as they can offer dedicated services within their data centers and colocation centers. Businesses also have the option to rent dedicated servers from a managed service provider on an hourly, monthly, or weekly basis.

How do Bare Metal Servers Work?

The workflow of a bare metal server optimizes the server infrastructure because it meets an organization's specific data storage and computing requirements.

Most organizations find it difficult to manage the daily operations of these servers.

External service providers may prove to be a benefit for companies. IT departments can focus on business operations and not server maintenance.

Let's look at some of the most important daily processes that ensure the smooth operation of bare metal servers.

1. Regular OS & Software Updates are Necessary

Servers perform better when the operating system and other components of their software are regularly updated.

These updates and patches are essential to secure data and protect servers against external attacks.

Other server components such as firewalls or switches must also be monitored and thresholds set to ensure server security from outside intrusion.

2. Install Firewall and Security Rules

Traffic management is essential for any component of a network, and bare metal servers are no exception.

Each server instance is different, so it requires close monitoring and attention.

You can create firewalls and security rules that apply to different situations and then modify them as necessary.

Based on IP addresses, portals, and IP rules, the firewall restricts ingress and egress traffic. These rules are essential to maintain a seamless workflow of servers and prevent suspicious traffic from being sent.

3. Operational Management is Crucial

All internal employees within an organization can access their resources directly and interact with them without any restrictions.

Each team member is directly connected to the underlying hardware so it is important to limit interaction.

This can be achieved by segregating users according to their roles and responsibilities and giving them different permissions for server interaction. The server will be protected from physical vulnerabilities.

Operational management includes other tasks such as data backup and recovery, data migration, and fixing and replacing hardware components. These functions enable the servers to function smoothly.

Bare Metal Servers are of Vital Importance

Bare metal servers are becoming more important to enjoy stable digital connections due to growing digitization. These servers address the problems that can arise while maintaining a virtualized environment. They also provide an organization with a secure, reliable, and strong networking foundation.

The gaming industry relies on bare metal servers to handle high-latency and CPU-intensive workloads. These servers are also crucial in the financial, aviation, and online media industries (YouTube. Netflix. Disney).

They generate huge amounts of data every second. The major players in the bare metal server market include Oracle, OVHcloud, and CenturyLink. Zenlayer is another.

1. High Performance

When compared to other servers, bare metal servers can deliver top-quality execution of tasks. The server's dedicated nature means that all resources are available for one client. This results in high performance.

This arrangement works well for many applications, including eCommerce shops, databases, VMs, and mobile apps as well as hosting sites. If your website is slow, you should consider using a bare metal server to speed up operations.

2. Servers can be Customized

Users have full control over the hardware and can modify server resources to suit their needs. The user can, for example, segregate resources in multiple VMs and customize them for specific tasks or dedicate them to a single application.

According to Semrush data from September 2022, amazon.com is the most popular website in the US. These sites can easily be hosted on a simple bare metal server.

Servers with more processors are also more powerful and can handle large workloads. Server customization according to requirements is another benefit for the company.

3. Enhanced Security

Bare metal servers can isolate data, resources, and programs as well as applications. They offer greater security and privacy than other hosting servers. They reduce the attack surface and hackers cannot steal sensitive or personal data because it is difficult to access them.

This isolated environment allows companies the ability to adjust firewall settings to suit their needs and increase their security base.

4. Scaling Options

You have the option to scale horizontally or vertically with bare metal servers. If the current server is unable to handle the workload, scaling vertically means upgrading to a more powerful server. This can be done by migrating to another server that has more RAM.

Horizontal scaling involves installing additional servers to spread the workload of the original server. If the network system is currently hosted on one server and you anticipate a larger workload in the future you can move the database to another server.

5. Reliable Services

Because the architecture is only one tenant, bare metal servers can provide reliable services. This means that workload spikes caused by noisy neighbors will be negated. This decreases the chance of server downtime, which in turn increases server performance.

6. Management of Support Well

Bare metal hosting is more customizable than shared or VPS hosting. Servers with bare metal servers have specialized administrators who can troubleshoot issues arising from specific configurations.

Server management requires an understanding of the operating system, security features, and services provided. Although managing bare metal servers is easier because they can be managed remotely, it's much more manageable. Routine OS updates also apply security updates.

7. Windows Support

Windows is used by many applications that we use every day. Windows Server versions are available for bare metal servers, making it easier to manage them for those who are familiar with the Windows OS.

Leasing or Buying a Server? A Business Perspective

Based on their business requirements, organizations can rent or buy a server. It is expensive to buy a server, but it allows you to access and control the server hardware from anywhere. You will also have to pay for the initial and any additional costs associated with maintaining the server.

Leasing seems to be the most popular option for companies due to its affordability and convenience. You don't have to maintain the server in such cases.

You can get immediate help if there are technical issues or the server is not performing as it should. It is also possible that you will need to keep track of and notify the service provider of any changes.

The decision to buy or rent a bare metal server is based on an organization's goals, needs, and future vision.


The IT sector plays a crucial role in the use of bare metal servers. This single-tenant architecture is also used by many other industries, including healthcare, fintech, and adtech.

infrastructure-as-a-service (IaaS), providers offer bare metal servers that can be used to host cluster resources that are scalable, and accessible worldwide. They can also be used to hybridize IT infrastructure, combining bare metal with a virtual environment.

Bare metal solutions can be a good choice for organizations that need secure, flexible, affordable, customizable IT systems.
