Defining Bare Metal
A bare metal server is a physical server dedicated to a single tenant without any virtualization layers. It provides direct access to the server’s hardware resources, such as CPU, memory, storage, and network capabilities, allowing the tenant’s applications and operating system to harness the server’s full power without interference from hypervisors or other virtual machines.
Bare metal servers typically live in a provider’s data centers. The provider is responsible for the maintenance and upkeep of the hardware. They are also responsible for providing the space, power, and network connectivity. With a bare metal, you are paying for dedicated server resources like a utility. The provider’s service level agreement (SLA) guarantees uptime and performance.
The Anatomy of a Bare Metal Server
A bare metal server’s architecture is inherently simple, yet robust, making it a go-to choice for many performance-critical applications. Let’s delve deeper into its key components:
Physical Hardware: At the heart of a bare metal server are its physical components. These include:
CPU (Central Processing Unit): This is the brain of the server, responsible for executing commands. On a bare metal server, the CPU isn’t shared, ensuring maximum processing power.
Memory (RAM): This temporary storage area is where the server processes data. Without virtualization, a bare metal server can utilize all available RAM more effectively.
Storage: Whether using HDDs (Hard Disk Drives) or SSDs (Solid State Drives), the storage on a bare metal server is direct and often faster, as there’s no hypervisor mediating access.
Networking Components: NICs (Network Interface Cards), switches, and other networking hardware determine the speed and efficiency of data transfer.
BIOS and Firmware: Often overlooked, the BIOS (Basic Input/Output System) and firmware on bare metal servers can be optimized for specific workloads. This allows for even more granular control and performance tuning.
Whether it’s for a high-end gaming server, a crucial database server, or latency-sensitive applications, the raw power and direct access of bare metal are hard to match.
Colocation, VPS, and Cloud vs. Bare Metal
To better understand where bare metal sits in the technology ecosystem, let’s explore the competing and complimentary technologies of colocation, virtual private servers, and cloud.
Colocation vs. Bare Metal
Colocation involves housing privately-owned servers and networking equipment in a third-party data center. The colocation provider delivers the space, power, cooling, and network connectivity. Customers are typically responsible for purchasing and maintaining their own servers and storage capacity.
Bare metal includes the benefits of data center colocation, but adds server hardware as part of the service. The service provider is responsible for the maintenance and uptime of the server. The hardware is also delivered as a service, making it an operational expense, rather than a capital expense.
Virtual Private Servers (VPS) vs. Bare Metal:
VPS hosting leverages a hypervisor to create multiple virtualized servers on a single physical machine.
The system allocates distinct virtual environments to users, with each one emulating a standalone server. They have the flexibility to choose their operating system and adjust their resource allocation, but they share the underlying physical resources with other VPS tenants.
Bare metal servers, in contrast, provide a dedicated physical environment. They combine the exclusive access of owning a physical server with the operational advantages of a managed service. Instead of sharing resources and potentially facing performance issues due to virtualization overhead, clients get the full capacity of the server. VPS services are typically less expensive, while bare metal services typically offer better performance.
Cloud vs. Bare Metal:
Cloud computing offers an abstracted layer where users can provision and manage resources from a vast pool, often distributed across multiple locations. Its design offers high scalability and flexibility to cater to both small and large-scale operations. Providers typically bill resources based on usage, and users often lack direct control or knowledge of the specific physical infrastructure that supports their operations.
Bare metal servers, on the other hand, strip away this abstraction, giving users direct access to a server. While cloud solutions dynamically scale based on demand, bare metal delivers consistent, predictable performance. Bare metal also gives users full access to the resources of the server for a fixed monthly price. This eliminates the uncertainty of variable billing in the cloud service model.
Advantages of Bare Metal Servers
Bare metal servers provide a range of benefits such as enhanced performance, increased security, and extensive customization options. Their dedicated resources and physical separation from other tenants eliminate the “noisy neighbor” effect, ensuring better performance.
Bare metal servers also provide enhanced security through physical isolation, which is unavailable on virtual private servers (VPS) or shared hosting. Additionally, extensive customization options allow you to fine-tune hardware and software configurations to meet specific needs.
Bare metal servers stand out for their exceptional performance. By providing dedicated resources and eliminating the “noisy neighbor” effect, bare metal servers ensure that your applications and workloads have exclusive access to the resources they need, resulting in better performance.
This is particularly beneficial for high-performance computing tasks, such as AI, machine learning, and big data processing, which require maximum performance and minimal latency.
Bare metal servers offer distinct security advantages due to their inherent nature of dedicated resource allocation. Unlike shared or virtualized environments, where multiple tenants reside on a single physical machine, bare metal servers cater to a single user or entity, ensuring complete isolation from malicious users. This segregation greatly reduces the risk of cross-tenant breaches or vulnerabilities that might arise in multi-tenant setups.
Furthermore, without the overhead of a hypervisor, there are fewer layers and entry points for potential attacks. Organizations have full control over the server’s security configurations, allowing for the implementation of tailored security protocols, stringent firewall rules, and custom monitoring without the constraints or potential vulnerabilities of shared environments. This direct access and control, combined with dedicated resources, make bare metal servers a preferred choice for security-conscious organizations.
Bare metal servers provide you with a wide array of customization options, enabling you to adapt the hardware and software configurations to your unique needs. With full control over the server environment, you can choose bare metal servers with the operating system, hardware components, and software applications that best suit your requirements on bare metal systems.
This level of customization enables you to optimize your server for performance, security, and reliability, ensuring that your applications and workloads run smoothly and efficiently.
Disadvantages and Limitations
Notwithstanding their many benefits, bare metal servers also have some disadvantages and limitations. These include higher costs, limited scalability, and longer deployment times compared to virtualized environments.
The relatively higher cost compared to VPS is one of the primary drawbacks of bare metal servers. Due to their dedicated resources and upfront investments in hardware provisioning and customization, bare metal servers can be more expensive than virtualized alternatives.
However, the superior performance and security provided by bare metal servers may justify the higher cost for businesses with demanding workloads or strict security requirements.

Compared to virtual machines that can be provisioned swiftly and effortlessly, scaling with bare metal servers can pose more challenges. Expanding the resources on a bare metal server requires purchasing more physical hardware. This leads to potential manual intervention and possible longer deployment times. As a result, businesses with fluctuating resource requirements may find it more difficult to scale their infrastructure using bare metal servers.
Owing to hardware provisioning and customization requirements, bare metal servers may take longer to deploy than virtual machines. While virtual machine servers can be deployed in a matter of minutes, deploying a bare metal server can take several hours or even days, depending on the level of customization needed. This longer deployment time may be a drawback for businesses that require rapid server provisioning and deployment.
That said, most dedicated server providers list what servers are currently available in their data center. If you choose from readily available hardware, deployment times for your bare metal environment can be closer to that of shared hosting servers or cloud hosting.
