What Is Bare Metal Cloud?

Bare Metal Cloud

Bare metal cloud is a type of cloud service that offers dedicated physical servers to users, as opposed to virtualized computing resources. Unlike traditional cloud services that run multiple tenants on a single server through virtualization, bare metal cloud provides users with exclusive access to the entire server's hardware. This approach eliminates the overhead associated with virtualization, allowing for enhanced performance, better control, and improved security.

Note that while bare metal servers traditionally offer direct access to hardware without a virtualization layer, many modern bare metal cloud providers include a lightweight virtualization or hypervisor layer. This layer, often minimal and designed to be efficient, enables advanced features like rapid provisioning, remote management, and security isolation. It does not significantly impact performance.

With bare metal cloud, users get full access to the capabilities of a physical server without sharing resources with other tenants. That is to say, they won't have to put up with so-called 'noisy neighbors'. This ensures that the server's resources are fully available to the user, which is particularly beneficial for resource-intensive applications. Without the overhead of virtualization, applications can run more efficiently with lower latency and higher throughput. This is crucial for performance-critical tasks where every microsecond counts.

Users have the freedom to install and configure any certfied operating system or software stack, tailored to their specific needs. This flexibility is ideal for organizations that require specific configurations and optimizations for their workloads. Dedicated servers reduce the risk of side-channel attacks and other security vulnerabilities associated with multi-tenant environments, providing a higher level of security and compliance for sensitive data and applications.

Bare metal cloud is particularly suitable for workloads that demand high performance, consistent and predictable latency, or specific hardware configurations. For example, high-performance computing (HPC) tasks, such as scientific simulations and financial modeling, benefit greatly from the dedicated resources of bare metal servers. Big data and analytics applications, which often involve complex data processing frameworks, can achieve optimal performance with bare metal infrastructure.

FAQs

  1. What's the difference between bare metal and cloud compute? 
    Bare metal cloud provides users with dedicated physical servers, giving them exclusive access to the server's hardware without the overhead of virtualization. In contrast, traditional cloud compute services use virtualized environments where multiple tenants share the same physical server. This means bare metal cloud offers better performance, control, and security, whereas cloud compute services offer more flexibility and scalability with lower upfront costs.
  2. Is bare metal less costly than cloud? 
    Bare metal cloud can be more expensive than traditional cloud compute services due to the dedicated nature of the hardware. Users pay for the entire server regardless of usage, which can lead to higher costs if the server is not fully utilized. However, for workloads requiring high performance and dedicated resources, the cost may be justified by the improved performance and control. It is important to note that the application software used must be able to scale to the capacity of the instance to fully leverage the benefits of bare metal cloud. This scalability ensures that resources are utilized efficiently, potentially balancing the overall cost with the performance gains achieved.
  3. What are the security advantages of bare metal cloud? 
    Bare metal cloud provides enhanced security by eliminating the risks associated with multi-tenant environments. Since users have exclusive access to the physical server, there is a reduced risk of side-channel attacks and other vulnerabilities that can arise from sharing hardware with other tenants. This makes bare metal cloud a preferred choice for sensitive and mission-critical applications.
