Which Is Finer: Bare Metal or Virtual Machines (VM)?

November 17, 2022 / Dedicated Servers

Both bare metal servers and virtual machines (VM) are potent hosting solutions, it might be challenging to decide which to use. On bare metal servers, VM runs, but the additional hypervisor strains performance and multi-tenancy can jeopardize security. However, bare metal servers might be a pricey hosting option that not everyone can afford. Which one do you decide on then? To assist you in deciding which option is best for you, we will compare and contrast bare metal and virtual machines in this post.

A Bare Metal Dedicated Server: What is it?

Even the most challenging web hosting applications can be powered by bare metal servers, which are single-consumer hosting solutions. Contrary to the hardware of shared hosting servers, the hardware parts of bare metal servers are not shared with other consumers.

High processing power, reliable and constant performance, and absolute security are the hallmarks of bare metal servers. They enable you to scale your dedicated server by attaching more hardware and are very customizable as well.

Dedicated servers hosting are another name for bare metal servers. You are the sole user in that hosting area when you host on a bare metal server. Therefore, all of the physical resources on the server are available to your hosted apps and services.

A Virtual Machine: What is it?

Software-based servers are hosted on virtual machines. A single bare metal server hosts several VMs. To build distinct VMs on top of the bare metal server, a layer of application known as a hypervisor is deployed. Additionally, the hypervisor is utilized to proportionally distribute hardware resources among all the virtual machines.

Due to the hypervisor, new VMs can be generated instantaneously and deleted at any time if they are no longer required. On a single server, all the hardware resources – including the CPU, GPU, RAM, and storage – are shared by all the VMs that are built there. Because of this, VMs can host several tenants.

VMs perform on par with bare metal servers in terms of speed. However, the inclusion of a hypervisor and other VMs running on the same server affect their performance.

6 Key Differences Between Bare Metal Servers and Virtual Machines

Bare metal servers run virtual machines. The two hosting solutions are distinct from one another, nonetheless, due to several significant differences. Here are the 6 key distinctions between bare metal servers and virtual machines:

  1. Security The most secure hosting option available is bare metal servers. They enable the installation of specialized security software and protect the server from viruses. Additionally, because there is only a single user on the server, your server security will not be compromised by other consumers. Whereas the security of multiple users hosting on the same server can be jeopardized if one of the VMs on a bare metal server has a security issue.
  2. Performance VMs and bare metal servers use the same hardware. The distinction is that several hosts running VMs share the same hardware. All the VMs on the same bare metal server will notice a decrease in performance when the hardware is shared by users and just one of them temporarily requests additional power. A portion of the bare metal server’s resources is utilized by the hypervisor used to produce VMs instances, leaving fewer resources for the VMs to share.

  3. Customization You can alter bare metal servers at any point during your hosting agreement. You can choose from basic dedicated hosting options and upgrade them if you want to, or you can start out by building your own unique dedicated server. VMs cannot be customized since you cannot choose the components that go inside of them. Instead, you can pick from different configurations and increase the number of virtual machines for better performance. Burts in performance can be accommodated by having this process run automatically.
  4. Deployment The time it takes to deploy a new server after purchase is another significant difference between bare metal and virtual machines. A dedicated server can be supplied in as little as a few hours or as much as over 24 hours after you purchase it. You may need some time to move your files to a dedicated server and begin hosting. However, because virtual computers are immediately built when you order them, they are provided practically instantly. Your virtual machine is available for use right away.
  5. Scalability Bare metal servers and VM can be scaled simply, but they do it in various ways. Physical hardware switching is necessary to scale a bare metal server. If you scale up in response to a spike in site traffic, you can easily miss it and end up with extra hardware. Scalability is accomplished considerably more quickly when VMs are used. When traffic spikes, VMs instantly increase the hardware resources to handle it without pausing your hosted services. When the traffic influx has passed, this procedure occurs automatically, and the server resources return to normal.
  6. Pricing Hosting packages can be invoiced either monthly or per hour. Depending on the server configuration you have selected, you will pay a certain monthly fee. You will have to pay for a hardware upgrade if your hosted services require more resources. A utility-based approach is often used to charge for virtual machines. You will mostly only be charged for the resources that you are actually utilizing, and they are billed by the hour.

    The hourly price will rise as your server automatically scales as your virtual machine’s hosted services need more resources. As soon as you start using fewer resources, the price will decrease.

What should you buy: Bare Metal Server or Virtual Machine?

VMs and bare metal servers both offer top-notch hosting options and quality performance platforms for hosting your online services. But they work well for different things.

Bare metal servers are perfect for:

  1. Hosting essential applications that require consistent high-performance Hosting in significant sectors where security cannot be compromised
  2. Online learning environments
  3. Solutions for backup and storage
  4. News sources and the media
  5. Streaming IPTV services

Virtual Machines are ideal for:

  1. Applications being tested by developers and in need of robust hosting
  2. Scaling-up websites and applications for startups
  3. A website with seasonal traffic
  4. Businesses looking to reduce their hosting expenses
