Comprehensive overview of bare metal servers in cloud computing covering benefits performance characteristics use cases and considerations for high-performance workloads in dedicated environments
This document provides an overview of bare metal servers in cloud computing, explaining their benefits, use cases, and considerations for provisioning. Bare metal servers are single-tenant, dedicated physical servers that are fully customizable and ideal for high-performance computing and data-intensive applications. They are suitable for workloads such as ERP, CRM, AI, deep learning, and virtualization. Bare metal servers are more expensive than virtual servers but offer higher performance, security, and control. Understanding bare metal servers is essential for selecting the right infrastructure for your applications.
A bare metal server is a single-tenant, dedicated physical server. It is dedicated to a single customer. The cloud provider manages the server up to the operating system (OS). If anything goes wrong with the hardware or rack connection, the provider will fix or replace it and reboot the server. The customer is responsible for administering and managing everything else on the server.
Bare metal servers can be pre-configured by the cloud provider to meet specific workload packages or custom-configured according to customer specifications. This includes processors, RAM, hard drives, specialized components, and the OS. Customers can also install their own OS and certain hypervisors not available from the cloud provider, allowing them to create their own virtual machines and farms. Additionally, GPUs can be added to bare metal servers for accelerating scientific computation, data analytics, and rendering professional-grade virtualized graphics.
Because bare metal servers are physical machines, they take longer to provision than virtual servers. Preconfigured builds can take 20-40 minutes to provision, while custom builds can take around three or four hours. These times can vary by cloud provider. Bare metal servers are dedicated to a single client at any given time, making them more expensive than similarly sized virtual machines. Not all cloud providers offer bare metal servers.
Bare metal servers are fully customizable and can handle the most demanding environments. They are dedicated and intended for long-term high-performance use in highly secure and isolated environments. Clients have full access and control because no hypervisor is required. Since there is no sharing of underlying server hardware with other customers, bare metal servers are ideal for high-performance computing (HPC) and data-intensive applications that require minimal latency. They excel in big data analytics applications and GPU-intensive solutions.
Bare metal servers are suitable for workloads such as ERP, CRM, AI, deep learning, and virtualization. They are a good alternative in the cloud for applications that require high degrees of security control or apps typically run in an on-premises environment.
When comparing bare metal servers to virtual servers, the most important considerations are customer needs. Bare metal servers work best for CPU and I/O intensive workloads, offer the highest performance and security, satisfy strict compliance requirements, and provide complete flexibility, control, and transparency. However, they come with added management and operational overhead.
In contrast, virtual servers are rapidly provisioned, provide an elastic and scalable environment, and are low cost to use. However, since they share underlying hardware with other virtual servers, they can be limited in throughput and performance.
