An Internet-based network—commonly the Internet—is utilized to host and provide a centralized server resource known as a cloud server, which users can access as required. Cloud servers deliver processing power, storage, and applications similarly to a traditional physical server.
What is a cloud server?
A cloud server is a virtual server operating in the cloud on infrastructure managed by a cloud service provider. Historically, organizations had to buy and maintain their own physical servers to run and host applications and handle data processing and analytics. These servers were typically located on-site or in nearby data centers. Today, organizations can deploy virtual cloud servers anywhere globally. These virtual servers operate on physical servers that are acquired and managed by third-party cloud providers. Cloud servers offer the same performance, configuration options, and usability as physical servers. You can access an extensive range of cloud servers with various configurations, enabling you to run and host a wide array of applications and workloads in the cloud.
How does a cloud server work?

A bare-metal server (or physical server) is a tangible machine with circuits, memory, storage, and a CPU. It occupies physical space and requires electricity to operate.
In contrast, a cloud server, virtual server, cloud instance, or virtual machine (VM) is purely software-based but functions like a physical server. It is perceived as a physical server by other devices or connections.
Organizations run VMs on their own physical servers. However, cloud servers are virtual machines created and managed by a cloud provider, which owns and manages the underlying hardware and infrastructure.
Cloud computing, including cloud servers and other services provided by cloud providers, relies heavily on virtualization.
Virtualization
Virtualization involves creating and operating virtual instances of real IT resources. Multiple virtual servers can run on the same physical machine, sharing its computing resources.
With virtualization, hardware isn’t tied to a single operating system or configuration. Instead, various operating systems, workloads, and applications can run in fully isolated virtual environments. This isolation facilitates greater resource sharing and is often more cost-effective for businesses.
Provisioning
Cloud server provisioning involves allocating and configuring computing resources within a cloud environment to deploy VMs. This is done using APIs, which allow you to create, configure, delete, and manage cloud servers remotely.
The process begins with defining the desired server attributes—such as CPU, memory, storage, and network capabilities—along with the operating system and any preinstalled software.
Once these parameters are set, automated tools within the cloud platform instantiate the cloud servers, allocate resources, and configure networking and security settings. This enables quick and scalable deployment tailored to specific needs.
Typically, cloud servers come with a Linux-based OS. The choice of server type depends on the task, as some configurations are better suited for specific workloads.
Why is it called a cloud server?
When a computing resource is referred to as being “in the cloud,” it means it is delivered over a network like the Internet, rather than being physically present on-site and accessed directly. A cloud server is a prime example of a cloud computing resource, along with cloud storage, databases, networking, and software.
What are the benefits of cloud servers?
Cloud servers are essential to cloud computing, eliminating the need to purchase, operate, and manage physical servers. They can be used exclusively or alongside existing server infrastructure, and launching servers in the cloud is now easier and more configurable than ever. Various types of cloud servers are available to suit both business and personal needs.
Flexible Options
Cloud servers allow you to deploy almost any server architecture, regardless of the underlying hardware. You can select cloud servers based on specific requirements such as graphics capabilities, machine learning workloads, or networking functionality.
Meeting compliance objectives is straightforward, as you can choose the geographic region and even the specific location zone within the cloud computing environment for your cloud server.
Cost-Effective Management
Investing in physical servers used to be expensive and required extensive long-term planning. Purchasing a physical server meant committing to a significant investment for many years. In contrast, you can now rent cloud servers on demand with per-second billing. You can rent multiple cloud servers simultaneously for different workloads without being locked into long-term contracts.
Cloud servers also eliminate ongoing maintenance costs. The cloud provider handles various management tasks, including operating system maintenance, configuration, and security updates, reducing the need for in-house management.
Furthermore, since cloud servers are defined in software, they do not degrade over time, avoiding decommissioning costs associated with retiring hardware-based servers.
Scalable Provisioning
Cloud servers often offer scalability. If you need more space or power, you can configure the server type or increase the number of servers automatically to handle larger workloads. Conversely, you can also scale down automatically to accommodate smaller workloads.
Cloud servers typically include mechanisms for high availability, such as advanced load balancing and built-in failover options.
What is the difference between a cloud server and a traditional server?
“The cloud” is often equated with the Internet as a whole. However, there are numerous types of clouds, both public and private, consisting of interconnected servers that provide computing resources over a network.
A cloud server differs from a traditional dedicated server. While cloud server resources can be shared among multiple users, a dedicated server is intended for the exclusive use of a single company. The organization must set up and manage a dedicated server itself, whereas a cloud server can be owned and managed by a third party.
What are the types of cloud servers?
Cloud servers can be deployed in three main types of cloud environments:
Public Cloud: Cloud servers are most commonly deployed in the public cloud. In this setup, a third-party provider owns and manages the servers and infrastructure, offering customers access to on-demand computing services.
Private Cloud: A company can privately host its own cloud servers, maintaining full control over their management and maintenance. These server resources are not shared with other organizations, but because they are cloud-based, they can be accessed remotely by employees, usually via a company intranet or VPN.
Hybrid Cloud: A hybrid cloud combines public and private clouds with on-premises and off-site cloud servers working together. This environment provides companies with greater flexibility, allowing them to maintain control and security when needed while also leveraging public clouds to quickly scale up during demand surges.
What are some use cases for a cloud server?
A cloud server can handle a wide range of workloads. Here are some examples:
- Enterprise software, like human resources (HR) and customer relationship management (CRM) systems.
- Customer-facing applications, including mobile apps and document management systems.
- High-end graphics processing, such as video streaming and gaming.
- Scientific modeling applications.
- Databases that are managed through incoming queries.
- Web applications and websites, hosted on dedicated web servers running HTTP communications.
- Machine learning (ML) workloads, used for training ML models that demand significant computing power.
