Bare Metal Servers are also called Dedicated Servers or dedicated servers. A Bare-Metal-Server refers to a physical server without pre-installed software or operating system, which is fully dedicated to a single user or application. Unlike cloud or virtual servers that share resources among multiple users, a Bare-Metal-Server offers dedicated hardware resources exclusively reserved for one tenant.
Difference from virtualized environments
The essential difference from virtualized servers lies in the exclusive availability of hardware resources. While virtual machines (VMs) run on a shared physical machine with resources managed by a hypervisor, a Bare-Metal-Server has direct access to all physical hardware. This eliminates the overhead and potential performance losses that can occur due to the virtualization layer.
Basics of Bare-Metal architecture
The architecture of a Bare-Metal-Server focuses on physical components such as processors, memory, storage space, and network interfaces. This allows for a customized configuration according to specific technical and business requirements. Companies can fully control the hardware and software, which not only leads to better performance but also meets security and compliance requirements.
Advantages and disadvantages of Bare-Metal-Servers
Vorteile
- Performance: Unmatched performance through direct access to full hardware resources.
- Customizability: Full control over hardware configuration, including choice of operating system and software.
- Security: Enhanced security through dedicated hardware and complete control over security settings.
Disadvantages
- Costs: Higher costs compared to virtualized environments due to dedicated hardware.
- Complexity: Requires technical expertise for setup, maintenance, and optimization of hardware and software.
Bare-Metal-Servers offer a robust solution for applications with high performance requirements that also demand flexibility and security. They are ideal for businesses that need a reliable and high-performance infrastructure and are willing to bear the additional costs and complexities associated with dedicated hardware.
Target groups for Dedicated Servers
- Large enterprises that need a secure, reliable, and high-performance hosting solution.
- Software developers and research institutions that test specialized applications where precise hardware specifications are required.
- The gaming industry, especially for game developers or hosts of multiplayer online games, where low latency and high performance are crucial.
In practice, online shops can benefit from the high availability, reliability, and fast scalability of Bare-Metal-Servers.
A practical example:
An online shop’s 25th anniversary is approaching. As part of this, the shop is planning an extensive discount campaign. The operator expects a significant increase in traffic. To handle this, the shop could use a Bare-Metal-Server that offers maximum performance and availability. The team could implement specific security measures and configure the hardware so that automatic scaling takes effect during traffic peaks: This way, the online shop can offer its customers a smooth shopping experience and doesn’t have to fear lost sales due to downtime.
Thus, Bare-Metal-Servers or Dedicated Servers are a powerful solution for those who need maximum control, performance, and customizability of their IT infrastructure.
