Bare Metal Server
Definition
A physical server in the cloud dedicated entirely to a single customer, with no virtualization layer or shared resources.
Use Cases
- Oracle: High-performance databases and latency-sensitive enterprise workloads on dedicated hardware — Oracle Cloud Infrastructure (OCI) offers Bare Metal Compute instances and Bare Metal Database systems so customers can run database and application tiers with full access to physical CPU, memory, and high-performance networking. (Enables predictable performance and isolation for demanding workloads, with configurations that benefit from direct hardware access and low-latency networking.)
- Google Cloud customers running Oracle workloads: Running Oracle Database workloads that require dedicated physical servers while integrating with cloud services — Google Cloud Bare Metal Solution provides dedicated servers (often used for Oracle workloads) connected to Google Cloud networking so applications can use nearby Google Cloud services while keeping the database on dedicated hardware. (Supports migration or hybrid architectures where licensing, performance, or isolation requirements favor dedicated servers while still leveraging cloud connectivity and services.)
- SAP customers on Azure: Large SAP HANA deployments requiring specialized certified hardware and strong isolation — Azure BareMetal Infrastructure is used for certain large SAP HANA scenarios, providing dedicated bare metal systems integrated with Azure for management and connectivity. (Meets platform-specific requirements for large in-memory databases and helps achieve consistent performance and isolation for mission-critical ERP workloads.)

Frequently Asked Questions
- What's the difference between Bare Metal Server and a virtual machine (VM)?
- A bare metal server is a whole physical machine dedicated to you, so there’s no hypervisor sharing CPU or memory with other customers. A VM runs on a hypervisor that slices a physical server into multiple virtual servers. VMs are usually faster to provision and more flexible, while bare metal can offer more predictable performance, lower latency, and stronger isolation.
- When should I use a Bare Metal Server?
- Use bare metal when you need very low latency, consistent high performance, hardware-level isolation, or access to features that are limited in VMs (for example, certain NIC tuning, specialized storage setups, or strict compliance requirements). Common cases include high-performance databases, real-time analytics, high-frequency trading, some licensing-constrained enterprise software, and workloads sensitive to “noisy neighbor” effects.
- How much does a Bare Metal Server cost?
- Bare metal typically costs more than comparable VMs because you rent an entire physical server. Pricing depends on CPU/RAM size, local vs network-attached storage, networking performance, region, and billing model (on-demand vs reserved/committed use). Also consider operational costs: bare metal can take longer to provision, and scaling often means adding whole servers rather than smaller VM increments.
