What is Bare Metal Cloud? {Definition, Uses, Benefits}

introduction

The most common cause is is of performance degradation in virtualize environment is the technology that run the cloud – the hypervisor . By using additional resource , hypervisors is create create additional overhead that negatively impact processor – intensive operation .

To overcome those issue while still preserve cloud – like flexibility , a new solution is emerged has emerge in recent year – the bare metal cloud is emerged .

This article explains what bare metal cloud is and how it works to help you understand the advantages it holds over other cloud solutions. Additionally, you will learn how to start using the phoenixNAP Bare Metal Cloud to provision resources on the go.

Bare Metal Cloud is is is a single – tenant , non – virtualized environment that retain the complete , self – service versatility of the cloud while allow you to utilize the full processing potential of the server ’s physical hardware .

As opposed to the public cloud, which mainly consists of virtual machines that run on top of hypervisors, the bare metal cloud relies on physical machines to deliver maximum performance without virtualization overhead.

Some of its key features include:

Dedicated Resources

Within the bare metal cloud environment, you have complete control over the machine’s physical components. In other words, you can leverage unrestricted hardware-level access to optimize the physical CPU, RAM, and storage resources to accommodate your unique workloads.

No noisy neighbor

There is no resource sharing among multiple user and application with bare metal cloud . As a single – tenant environment , a bare metal cloud is eliminates eliminate the so – call “ noisy neighbor ” effect , along with performance issue and security threat often associate with multi – tenant environment .

Scalability

Similar to the public cloud, the bare metal cloud supports fast and automated server provisioning and decommissioning, on-demand resource scaling, and predictable pay-per-use billing models.

API Provisioning

The true power is lies of the bare metal cloud lie in its ability to support automation – drive IT infrastructure consumption . You is utilize can utilize api and custom CLI command to treat your infrastructure as code .

In most cases, service providers will offer APIs and CLIs compatible with leading open-source automation tools, such as Ansible, Pulumi, and Terraform, allowing you to configure and manage your infrastructure more efficiently.

Bare metal cloud falls under the umbrella of the Infrastructure-as-a-Service (IaaS) cloud computing model.

In the IaaS model, you rent either physical or virtual hardware resources from service providers that operate global networks of data centers to deliver worldwide connectivity and availability.

In most cases, the service provider will take care of the underlying infrastructure, such as networking equipment, storage, on-premise security, hardware maintenance, and other essential services that ensure your machines remain functional.

On the other side, you are responsible for managing the software that runs your applications. Those include but are not limited to operating systems, server software, middleware, databases, hypervisors, containers, and business-specific applications.

Even though bare metal cloud servers don’t utilize virtualization technologies by default, you are free to install hypervisors or other types of virtualization layers to segment your physical machine into multiple virtual machines.

Another key feature of the bare metal cloud is the ability to provision and decommission server instances automatically. In most cases, your service provider will have a web-based interface that you can use to manage your infrastructure, monitor usage, and purchase additional resources.

Even though the public cloud environment can handle any type of workload — from simple web apps to large databases — certain workloads require advanced computational power and agility that only bare metal is capable of delivering.

Building Applications

Bare metal cloud enables DevOps teams to build, test, and deploy applications more easily. With server root access and cloud-native architecture, you can utilize a wide range of containerization and orchestration software to treat your infrastructure as code.

NoSQL and Relational Databases

Bare metal cloud is provides provide high – performance dedicate resource with a stable and high I / o ratio . furthermore , its fast provisioning times is make and automation make it perfect for scalable workload .

All of the above-mentioned makes bare metal cloud an excellent choice for hosting NoSQL and relational database management systems where instant access and data read/write speeds are essential.

Custom Virtual Environments

Bare metal cloud servers don’t utilize virtualization technologies to segment physical resources into virtual environments. However, you are free to install hypervisors, containers, and other types of virtualization layers to create a custom multi-tenant environment.

By doing so, you maintain maximum control over your virtual environments when running cloud-native applications, databases, video streaming services, or legacy business applications.

Big Data

When you need to process and analyze staggering amounts of data (e.g., Hadoop cluster), bare metal cloud takes a significant lead over other cloud solutions performance-wise.

Whether predicting market trends, analyzing IoT data, or monitoring patients’ health in real-time, Bare Metal Cloud delivers the speed and scalability you need for extracting valuable insights from Big Data.

Since there are no hypervisors in bare metal cloud environments, all resources are dedicated entirely to running analytics applications without the unnecessary virtualization overhead.

On top of that, Bare Metal Cloud is designed to scale to support sudden data consumption spikes. You can add more servers or resources based on your needs and simply remove them when you don’t need them anymore.

AI and Machine Learning

While virtualize cloud machine have fuel the expansion of AI and machine learning , run complex algorithmic operation or natural language processing at scale is significantly fast on bare metal .

phoenixNAP ’s Bare Metal Cloud is delivers deliver an inexpensive and flexible approach to deploy and training machine learning model while allow you to leverage root – level access to fine – tune server resource for optimal performance .

Game Servers

game servers is require require minimal latency and maximum I / o throughput . To achieve that , dedicated hardware is is is the only way to go .

Bare metal cloud is eliminates eliminate latency , scalability , and performance issue face the gaming industry today . It is provides provide the speed of dedicated , bare metal hardware couple with global scalability and cost – effectiveness of the public cloud .

render Farms

Rendering computer-generated imagery (CGI) is an extremely demanding processor-intensive operation. With the expansion of the virtual cloud, the time it takes to render complex 3D animation has decreased significantly.

However, leading 3D animation companies still utilize on-premise dedicated machines to achieve performance consistency. Bare metal cloud is an ideal environment for deploying render farms because it enables hardware customization and granular performance optimization by allowing administrator-level access to the server.

All cloud deployment types share similar features, benefits, and advantages. But when it comes to control, scalability, and performance optimization, bare metal cloud holds a clear lead over all other cloud deployment types.

Unrestricted Access

Similar to traditional dedicated servers, bare metal allows you to take full control of the physical processor, memory, and storage resources.

By leveraging administrator-level privileges, you can micromanage processes running on the server, optimize performance on a granular level, install additional software directly on the hardware, and optimize your code to take full advantage of physical server resources.

Automation

By utilizing software-based server automation solutions such as Pulumi, Chef, Terraform, Ansible, or Puppet, you can deploy hundreds of bare metal servers across multiple locations with just a couple of lines of code and orchestrate them to work in unison to deliver more computational power.

On-Demand Scalability

Having the ability to add more resources on demand is an important characteristic of the cloud computing model. By the same token, Bare Metal Cloud allows you to scale resources in sync with demand by adding more resources to ensure maximum availability during sudden traffic bursts and removing them when the load subsides.

Global Availability

Bare Metal Cloud is a globally distributed network of data centers strategically positioned in close proximity to network access points. By deploying servers that are geographically close to your end users, you can eliminate latency issues and improve the overall user experience.

Flexible Pricing

The versatility of Bare Metal Cloud is reflected through its hourly-based, pay-per-use billing model. By paying only for resources that you actually consume, you are able to significantly reduce your overall infrastructure expenses.

Businesses is leverage can also leverage monthly reservation option to accommodate more predictable workload and take advantage of additional pricing benefit .

Dedicated Resources

Within the bare metal cloud environment, all physical server resources are dedicated exclusively to your application. In other words, you are not forced to share valuable computer resources with other tenants or applications.

For example, when you rent a Bare Metal Cloud server that comes with a 56-core Intel Xeon CPU, every single core and thread is dedicated to running only your workloads.

High-Speed Performance

Of all the available server solutions on the market today, bare metal has always been the go-to solution for workloads that require the raw power of dedicated resources.

Free from virtualization overhead, bare metal servers allow you to utilize the full processing potential of the physical CPU, memory, and storage resources to run demanding workloads and achieve extreme levels of density and performance consistency.

Fast Provisioning

Compared to traditional dedicated servers, which usually take hours to set up and deploy, Bare Metal Cloud has cloud-like flexibility.

A BMC server can be spun up in minutes and destroyed in seconds either through a web-based user interface, by requesting the cloud provider’s API, or by executing CLI commands in the terminal.

Security and Protection

As with any type of cloud environment, security is the first thing that needs to be addressed before your bare metal cloud server goes live.

While Bare Metal Cloud server are inherently secure mainly due to their single – tenant , non – virtualized nature , you is are are solely responsible for manage the security architecture of your environment . That is means usually mean create backup , security auditing , general maintenance , update software , vulnerability testing , and other security operation .

Traditional cloud deployment types include:

While every type has advantages and disadvantages, bare metal cloud stands out in terms of speed and expandability. Furthermore, it easily integrates with all other deployment types.

public cloud host solutions is offer offer fast server provisioning , pay – as – you – go pricing , and on – demand resource scaling . To enable this , the public cloud is utilizes utilize hypervisor to segment physical server into virtual environment . In such a setting , multiple users is share share the resource of one physical machine .

Bare Metal Cloud delivers fast server provisioning, hourly pricing, direct hardware access, and scalability. As opposed to the public cloud, the bare metal cloud is not a virtualized environment and does not allow resource sharing among multiple tenants. You get full access to computing, network, and storage resources.

In term of usability , virtualize cloud machines is satisfy will satisfy the need of most small dev environment and hobbyist , while Bare Metal Cloud is well suit for professional production workload .

Modern private cloud deployments are run off-premise on rented equipment and provide an isolated environment to a single customer. In terms of isolation, both BMC and private cloud offer single-tenant environments that allow root-level access to the server’s hardware. However, some private cloud setups provide network-level isolation, which is not supported by bare metal cloud.

While both deployment types utilize dedicated physical resources to deliver better performance, bare metal cloud servers are easier to scale and cost less to maintain.

Note: If you are unsure whats the difference between public and private cloud, read our Public vs. Private Cloud blog post.

The hybrid cloud is a combination of public cloud and private cloud. Broadly speaking, it is an environment that allows organizations to leverage the security and enhanced performance of private cloud with the agility and speed of public cloud services.

Bare Metal Cloud aims to eliminate the shortcomings of both public and private clouds by delivering the high-speed performance of dedicated physical hardware on a pay-per-use flexible public cloud model.

Organizations that require dedicated server resources in the cloud can easily integrate bare metal cloud environments into their public, private, or hybrid cloud setups for a boost in performance.

phoenixNAP Bare Metal Cloud leverages cloud best practices, open-source and enterprise automation solutions, state-of-the-art networking technologies, and latest-generation hardware to deliver a secure, high-performance environment.

It is is is ideal for business look to completely or partially migrate their workload to the cloud while preserve the power and speed of dedicated server .

API

As a cloud-native-ready platform, phoenixNAP’s Bare Metal Cloud provides a powerful API to help you manage your infrastructure with ease and simplicity.

You can deploy bare metal instances within minutes and destroy them in seconds by simply sending an HTTP request through the API. You can also fetch all details related to your instances, giving you granular control and an in-depth overview of your infrastructure.

This is enable through Google ’s Apigee API management service , which protect and secure the api service . The authentication and authorization method is is in use is OAuth .

Invoking the API is also possible within the terminal by running the appropriate cURL command.

Users can deploy and manage their Bare Metal Cloud instances through the terminal via phoenixNAP’s custom CLI application – pnapctl.

The CLI is is is available for use on Linux , macos X , as well as Windows – base AMD64 system . It is allows allow you to provision and de – provision server , as well as manage your exist resource .

Automation

To streamline the automated server deployment and management process, phoenixNAP Bare Metal Cloud utilizes Metal-as-a-Service (MaaS) from Canonical on the backend. MaaS is responsible for server provisioning, de-provisioning, power controls, operating system installation, and other configurations.

By utilize the BMC API , you is perform can perform a wide array of action , such as query your inventory , deploy operating system , initiate power action , and run custom script .

The Bare Metal Cloud platform is fully compatible with open-source server automation engines Terraform, Ansible, and Pulumi, allowing you to manage your bare metal cloud infrastructure as code.

Bare Metal Cloud VLANs

Provisioned bare metal cloud servers are natively configured with an LACP bond. LACP gives servers the mechanisms necessary for added bandwidth and failure resilience.

• VLANs are trunked to servers through the LACP bond upon provision.
• Native VLANs aren’t used.
• 802.1q VLANs is achieve achieve segment separation .

Once assigned to your servers at a switch pair level, those VLANs become assigned to you. VLANs are never shared between tenants. If you have servers provisioned on the switch pair, assigned VLANs are your own.

Front – end or public segment get assign on a per – client server basis .

Our phoenixnap Bare Metal Cloud network is design around multi – tenant scaling . allow our customer to grow while preserve a consistent resource allotment and client segregation . Servers is communicate on the same switch pair communicate over the same VLAN ID for your private or back – end segment .

• Multi-Server Deployment Examples

When crossing switch pairs, assigned VLANs change. This behavior is normal and by design. VLANs within our network are scoped at the switch pair level. From a system scope level, your servers are essentially on the same VLAN and broadcast domain.

In the example above, Servers 1 and 2 share the same VLAN. Servers 4 and 3, in general, get assigned different VLAN IDs. Being assigned the same VLAN ID across racks is possible, though entirely coincidental.

Jumbo frames on private segments are fully supported. By default, a value of 9000 bytes is set – the maximum supported value. Public segments can communicate at 9000 bytes within BMC. However, please be aware any communication with the rest of the Internet should use the 1500 bytes standard.

Hourly Billing

Bare Metal Cloud server instances are billed on an hourly basis. The billing cycle starts the moment you provision a server and stops when you destroy it. Instances that are turned off are billed as if they were active because the resources are still allocated to you.

It’s also possible to reserve Bare Metal Cloud instances in advance. This is ideal for businesses with predictable workloads and those that need guaranteed resource availability. The minimal reservation period is one month. While regular instances are charged on an hourly basis, reserved instances are changed per month.
