 Bare Metal Server or Virtual Machine? A comparison

Servers are a crucial component of any organization's IT infrastructure. They host applications, websites, and databases, and provide computing power for various tasks. Organizations have two main options when it comes to deploying servers: bare metal servers or virtual machines. Choosing the right server technology can impact performance, scalability, costs, and ease of management. In this article, we will compare bare metal servers vs virtual machines to show all the pros and cons to help understand which option may be best for your business needs.

What exactly is a Bare Metal Server?

A Bare Metal Server is a physical server dedicated to a single tenant. The server is not shared with any other customers or applications. The server's resources such as processors, memory, storage, and network bandwidth are allocated to the single user. The operating system and software run directly on the hardware without any virtualization or hypervisor layer in between.

Bare Metal Servers provide dedicated and isolated computing resources. There is no competition for resources from neighboring virtual machines. This enables predictable high performance and low latency. Bare Metal Servers also offer flexibility and customizability since organizations have full control over the server hardware and software. You can select the processors, memory, storage, network cards, and operating systems based on your specific workload requirements. bare metal server Bare metal servers usually have a module style to provide a wide range of customization

What are Virtual Machines?

A Virtual Machine (VM) simulates a computer system in software. The Virtual Machine runs on top of a physical server and shares the underlying hardware resources with other Virtual Machines. A hypervisor software creates and manages the Virtual Machines and allocates compute resources dynamically to each VM.

The virtualization layer abstracts the physical hardware into virtual resources that can be assigned to VMs. So a single physical server can host multiple Virtual Machines that are isolated and have their own virtual CPUs, memory, storage, and network interface cards. The allocation of resources is flexible and can be changed on demand.

When comparing Bare Metal Servers vs Virtual Machines, it offers excellent scalability and elasticity. You can easily create, copy, move, and reconfigure VMs to meet changing workload demands. The ability to consolidate multiple VMs onto a single server also improves hardware utilization compared to dedicating an entire server per workload.

Some main differences between Bare Metal Servers vs Virtual Machines

When considering Bare Metal Servers vs Virtual Machines, you should consider this basic fact: Virtual Machines run and operate on bare-metal servers. However, there are key differences between the two hosting solutions that make them different. So here are all the main differences between Bare Metal Server and Virtual Machine:

Security

Security is a significant component of the bare metal vs Virtual Machine argument, as it is in other hosting issues. To begin, you should be aware that bare-metal servers are the most secure hosting solution available. They enable the installation of bespoke security software to protect the server against infection. Furthermore, because there is only one user on the server, there are no hosting neighbors that may compromise your server's security. In contrast, several Virtual Machines run on a single Bare Metal Server, and a security hole in one of them might jeopardize the security of all Virtual Machines hosted on the same server.

Performance

As we mentioned above, Virtual Machines and Bare Metal Servers use the same hardware. However, one essential aspect to consider in the Bare Metal Server vs Virtual Machine debate is that the same hardware is utilized by different hosts to operate multiple Virtual Machines.

When hardware is shared among users and only one of them requires extra power for a short period, all other Virtual Machines on the same Bare Metal Server experience a performance reduction.

The hypervisor used to produce Virtual Machine instances consumes some of the bare-metal server's resources, which is why the performance of the Bare Metal Servers is always better than Virtual Machines when both of them have the same specs.

Operating and maintain costs

The cost of owning and maintaining the server is a key consideration in the Bare Metal Server vs Virtual Machine debate. Monthly pricing options for Bare Metal Servers are more widespread, with prices starting around $50 per month. Depending on the server configuration you select, you will pay a set monthly fee. You will have to pay for a hardware upgrade if you want more resources for your hosted services.

Virtual Machines, on the other hand, are often billed in a utility-based manner. They charge by the hour, and you will only be charged for the resources that you are actively utilizing. If your resource utilization is excessive, the cost might range from a few cents per hour to a few dollars.

When your Virtual Machine-hosted services require additional resources, your server will automatically expand, and the hourly fee will rise. As your resource use decreases, so will the price.

Customization

Customization of Bare Metal Servers is possible at any moment throughout your hosting contract. You may start by building your unique dedicated server, or you can select from basic dedicated hosting plans and enhance them later if necessary.

Because you cannot choose which components go into Virtual Machines, they are not configurable. Rather, you may select from several setups and add more VM instances for increased performance. This method can be automated to handle performance spurts.

This is a crucial factor to consider when deciding between a Bare Metal Server and vs Virtual Machine since it allows you to customize the hosting solution to the needs of your business applications.
