Bare Metal VS Cloud Server

What differentiates a bare metal server against a cloud server? You’ve heard about cloud servers everywhere but do you know if they really are better than bare metal servers?

The basic differences between bare metal servers and cloud servers

The bare metal server

Bare metal servers offered at competitive prices with world class support.

The bare metal server is traditionally known as a dedicated server or a physical server. It’s installed within a datacenter in a controlled and highly monitored environment.

The server dedicates all it’s hardware resources (CPU, RAM, Storage, Network port) to a single tenant, you. You keep a dedicated access to all ressources and you don’t have to deal with performance variations and degradation.



The cloud server

When you buy your cloud server you get a virtualized server. This server is using a portion of the CPU, RAM and storage on it’s host machine.

Select between bare metal server or cloud server instances to suit your needs.

The host machine shares it’s resources with multiple virtual instances. They each get a portion of CPU, RAM and storage.

The cloud server, in the more popular configurations, receives a small portion of a bigger shared network storage. Rarely the cloud servers obtain a storage block from their compute node host.

We must stay aware that the word Cloud is often overused. When I talk about a public cloud I refer to an infrastructure generated from multiple compute nodes and a centralized storage system. We must not consider a VPS hosted on a single dedicated server a cloud instance.



Let’s go deeper in terms of CPU

When we compare the processor aspect of a cloud server and a dedicated server that have similar amount of cores and clock speeds the results are clear and obvious. Your dedicated server will outperform the cloud server because it has physical and direct access to the processing resources.

The dedicated server also has quicker and priority access to the processor cache as-well.

You also need to know that a single core of the latest generation of processors will often carry multiple threads per core. A vCPU however is a thread rather than a core.

That being said, not all hosting providers give you the same CPU model. And all CPU model does offer different frequencies.

Storage Wise

Generally the bare metal server uses local storage and the cloud server likely uses a network attached storage block.

Both can also be using HDD as well as flash-based (SSD) storage. All hosting is different here, depending on the technology and hardware used, and the QoS applied.

The main difference is that a bare metal server will use it’s own storage devices, with all the resources available for it. The cloud server uses shared storage with a bunch of other users.

We know cloud servers are sharing a pool of resources with other users. Because of that Quality of Service rules are implemented to deliver stable IOPS (input/outputs per seconds) to each cloud instance. Different packages may provide different QoS as well. Subsequently, the type of storage used will vary.

A caveat of shared pools of resources is that degradation of performance can be experienced if you have noisy neighbours on the same infrastructure.

What about the flexibility for bare metal servers compared to cloud servers?

You must now know the main highlight of a cloud server compared to it’s bare metal alternative; deployment. You can deploy cloud servers almost instantly whereas physical machines take longer to provision.

Cloud servers also have the possibility to “resize” your instance. You can increase your resources as you need them be it CPU, RAM or Storage.

When you choose to increase your storage capacity you generally can’t resize it back down afterwards. However, resizing quickly is a good option especially for your growing projects.

How can we help you?

GloboTech offers Cloud Instances based on OpenStack.

As a cloud server provider, we put a wide range of public cloud servers at your disposal. We designed an OpenStack based cloud infrastructure. We built it with passion and using state of the art components for peak performance throughput.

GloboTech cloud servers allow upgrade of CPU and RAM ressources independently of the storage capacity. By keeping the same storage size, GloboTech customers can simply resize the CPU + RAM when needed. Then, revert their original ressources.

Pay only for the resources allowed to the instance – Cloud servers at GloboTech are getting charge hourly.

You have a good advantage choosing one of our cloud products; you get your own private network within our cloud infrastructure. This enables you to design your own virtualized clusters for different types of workloads and increased redundancy.

If you need increased security we provide you with a security group system that you can customize to your needs. This system acts as a firewall outside of your virtual resources where you can restrain inbound and outbound access to specific ports. We also offer SSH key access at the creation of your server for added security.

What if use a dedicated server instead?

Your dedicated server allows you for a lot more flexibility in terms of possible upgrades. You can generally schedule a quick maintenance for hardware swaps mainly for CPU or RAM at any time with minimal downtime involved.

When we think about storage we can leverage the use of Software Raid 1 to increase the size of a storage array with minimal impact on service availability.

You need a private LAN between your dedicated servers? We’ll provide a private network interface of 1GBps or 10Gbps depending on your needs.

We are known to always find solutions to suit our customer’s various needs and do our very best to adapt our hosting offer to fit your most precise requirements.

Okay, so what’s best for me?

It’s all up to you. All things considered both types of infrastructure have their strong and weak points. We are qualified to help you tailor a solution that maximizes your budget while giving you the best infrastructure for your needs.

For smaller projects, which require shared hosting or VPS, a small cloud server can be perfect for your needs as they can grow on the same infrastructure for quite some time.

As most people know, the internet is not infallible. Servers go up and down all the time, due to hardware failure, configuration mistakes, network problems, etc. Many of those failures are often unpredictable and may cause headache to infrastructure owners and administrators. To help counter these potential issues, people have introduced the concept of “High Availability” or HA for short. This whole design philosophy hinges on the replication of network routes and websites data so that there is no single point of failure.


To reduce network latency, a Content Delivery Network (CDN) provides a series of alternative servers geographically spread throughout the world. By placing your static images on those servers, they are delivered more quickly, keeping download time to a minimum. In this article, we’ll explore how they work, when to use them, and how they are priced. Ultimately, if they are right for you.

Originally developed in collaboration with NASA, OpenStack is an open source project designed to build customizable cloud environments. Although the idea behind OpenStack is simple, the platform itself is not. In this article, we’re going to talk a little bit about how it works and how it can be beneficial to users who are considering using it.


The online hosting industry has undergone significant changes in recent years. Increasing numbers of business owners are opting away from traditional Internet hosting in favor of cloud service. If you are looking for a hosting service that is versatile, convenient and cost-efficient, you should consider cloud service when choosing a new hosting provider.

Several important characteristics of cloud services set them apart from traditional hosting providers. The virtualization layer of a cloud service, also called the infrastructure layer, is the product of numerous operating systems that have been installed as virtual machines. A hypervisor, also known as a virtual machine manager, is another prominent part of cloud hosting. It is a program that permits several operating systems to share one hardware host. A hypervisor ensures the efficiency of the entire process by allocating resources to each operating system as they are needed. It also ensures that the multiple virtual machines do not interfere with each other.

As a business owner with a significant online presence, you will find these components work together seamlessly to maximize the use of each system, enhance scalability and reduce overall costs for your business.

The growing popularity of cloud hosting also has changed the role of storage area networks (SANs) in the industry. In the past, businesses usually purchased a series of individual physical servers connected to SANs. The rise of cloud hosting has led to a move toward cost-efficient modular systems that encompass enough power to efficaciously operate a business’s applications.

If reliability and low rates are major considerations for your business’s online presence, you will discover that a public cloud server offers an impressive range of benefits. In the most general terms, a public cloud service provider sells cloud computing services to individuals and businesses online. As a business owner, you will find cloud computing services particularly valuable in ensuring that your online applications run consistently and efficiently.

Another advantage of cloud hosting is the ability to ramp up or reduce your business’s virtual machine resources on the fly. This process eliminates the hefty costs related to shifting from one dedicated server to another.

Fast provisioning is a feature of cloud computing that uses linked clones in virtual machine provisioning operations. Linked clones are copies of virtual machines that share a base disk with the first machine. This technique will help you save time and space in your operations.

Keeping applications up and running is a vital consideration for many businesses involved with cloud hosting. Quick failover, which refers to a fast and seamless switch to a new server in the event of a system failure, ensures that your customers will enjoy uninterrupted access to your online business.

When considering a cloud service for your hosting needs, also take elasticity into account. Cloud hosting gives you the ability to scale up or down quickly to meet the demands of your customer base. This feature saves your business money and allows you to pass along the added value to your customers.
