8 min read


A dedicated server is a type of hosting where the customer rents an entire physical server that is completely isolated from other users' servers. Unlike virtual hosting and VPS, where the resources of a single server are divided among several users by software, here all of the machine's resources, such as the processor, RAM, disk subsystem, and network channel, belong to only one tenant. This approach ensures maximum performance, a high level of security, and the ability to flexibly configure the server environment for any customer task.

Dedicated servers are located in professional data centers, where each server is connected to a high-speed network, powered by redundant power sources, and maintained by technical specialists who monitor the performance of the equipment.

This makes a dedicated server the optimal choice for projects that require a reliable, stable, and predictable IT infrastructure.

Who are dedicated servers suitable for?

A dedicated server is a rational choice when a project exceeds the capabilities of regular virtual hosting or VPS. In practice, such servers are chosen by companies and entrepreneurs who work with complex applications or high loads.

Main use cases:

  • large online stores with a large number of concurrent users;
  • SaaS applications and corporate services;
  • ERP and CRM systems;
  • projects with high peak loads (news portals, media platforms);
  • databases with complex queries;
  • game servers;
  • VPN, VoIP, and streaming platforms;
  • projects where security and physical isolation of infrastructure are critical.

Such cases require stability and no “neighborhood” with other clients, so dedicated servers meet this need better than other types of hosting.

 

 

 

 

What to choose, VPS or a dedicated server?

When choosing server infrastructure, most projects face two main options, such as VPS and dedicated servers. Both solutions are suitable for hosting websites, applications, and corporate services, but differ in their operating principle, level of available resources, security, and scalability options.

VPS is convenient when you need a balance between price and functionality, while a dedicated server is chosen when a project requires maximum performance, complete isolation, and flexibility in hardware configuration.

To better understand the differences between them, below is a comparison of these two popular solutions.

 

Table - Comparison of VPS and Dedicated Servers

Parameter VPS Dedicated Server
Performance Medium, resources are shared Maximum, resources are fully yours
Isolation Partial virtualization Full physical isolation
Hardware Control Limited by the hypervisor Full control
Scalability Fast but limited Requires server configuration change
Price Lower Higher
Security Depends on neighboring clients Maximum
Ideal Use Cases Small and medium projects High-load and mission-critical projects

This table will help you quickly determine whether a dedicated server is suitable for the specific requirements of your project.

 

 

 

 

 

How a dedicated server works

By accessing a dedicated server with a pre-installed operating system (Linux, BSD, or Windows), the customer can deploy any necessary infrastructure, such as databases, web servers, control panels, analytics systems, container environments, monitoring services, message queues, and other tools required for projects of any complexity.

In fact, the tenant manages the machine as if the server were located in their office, but they do not need to worry about ventilation and cooling systems, power supply, redundancy, or network infrastructure - all of this is handled by the data center. The customer gets full control over the software environment, including root access, which allows them to configure any software and manage all configurations at the OS level.

 

Additionally, the user can independently ensure the security of their server by taking the following measures:

  • configuring a firewall (iptables, nftables, ufw);
  • configuring SSH access by keys, disabling passwords;
  • installing status monitoring systems (Prometheus Node Exporter, Zabbix Agent, Netdata);
  • configuring logging and log management (rsyslog, journalctl, logrotate);
  • automating updates and security patches;
  • implementing Fail2ban or similar tools to protect against password brute force attacks;
  • using backup (local or remote);
  • configuring integrity checks and basic IDS/IPS mechanisms.

 

When configured correctly, a dedicated server provides the highest level of security, as it is physically isolated from other clients, and all settings are available to the server owner without any restrictions from the hypervisor, as is the case with VPS.

 

 

 

 

 

Advantages of using a dedicated server

Before moving on to specific use cases, it is important to understand why dedicated servers are considered one of the most reliable and productive solutions on the market. Unlike virtual hosting and VPS, where resources are distributed among multiple clients, a dedicated server provides full and exclusive access to all the computing power of a physical machine. This gives projects predictability, stability, and a high level of security, which is especially critical for large and resource-intensive systems.

Dedicated servers are used where high data processing speed, no external influence on performance, and the ability to flexibly configure the software and hardware environment to the needs of the business are important. Below are some of the key advantages that make a dedicated server the optimal choice for serious projects and corporate infrastructure.

 

Increased performance

All server resources belong solely to your project. No “noisy neighbors” or performance drops. This is especially important for high-traffic web projects, large databases, and real-time applications.

 

Full control

You can install any OS, software, and configurations. The administrator gets root access and the freedom to configure the server for specific business tasks.

 

Improved security

Physical isolation makes a dedicated server much more secure. Risks associated with neighboring virtual environments are minimized. And with the right security settings, including the measures described above, your dedicated server can become an impenetrable fortress.

 

Scalability

You can increase the volume or even the type of disk storage, the amount of RAM, or expand the channel for network traffic. All of this helps you easily adapt to the growth of your project. And if your project has grown rapidly or become suddenly popular, then you can increase the number of dedicated servers in your infrastructure.

 

Improved SEO

High speed and predictable performance are the ranking factors that Google considers key when determining the order of search results. A dedicated server often provides faster server responses, which has a positive effect on the position of your website or project in search results.

 

 

 

 

 

How to choose a dedicated server

The choice of a dedicated server depends not only on your budget, but also on the actual requirements of the project, such as load, traffic characteristics, application type, data volume, and expected future growth. An incorrectly chosen configuration can lead to a lack of resources, unstable operation, or, conversely, overpayment for capacity that is not actually used.

Therefore, before renting, it is important to evaluate the project architecture, understand which processes will consume resources, and determine which characteristics affect performance in your particular case. This is especially true for applications that are demanding on the CPU, disk subsystem, or network channel.

For example, if you plan to host a high-load database on a rented server, then the key parameter you should pay attention to is the type and volume of storage, because the faster the read-write operations are performed, the more productive your database will be.

Below are the key parameters to pay attention to:

  • processor type and generation (e.g., Intel Xeon or AMD EPYC);
  • number of cores and threads;
  • amount of RAM;
  • type and speed of the disk subsystem (NVMe, SSD, RAID);
  • channel bandwidth and number of IPv4;
  • data center geolocation;
  • availability of DDoS protection;
  • SLA and availability guarantees;
  • possibilities for further upgrades.

Making the right choice allows you to avoid unnecessary expenses and get the best price-performance ratio.

 

 

 

 

 

FAQ: frequently asked questions about dedicated servers

 

Can I transfer a project from a VPS to a dedicated server?

Yes. In most cases, migration is fairly quick. You simply copy the files, databases, and current service configurations. If the project uses containerization or CI/CD, the transfer is even easier, as you just need to deploy the environment on the new server and switch the DNS.

 

Is a dedicated server suitable for WordPress or other CMS?

Yes. Dedicated servers are well suited for websites on WordPress, Joomla, Drupal, and other CMS, especially with a large number of plugins, heavy database queries, or high traffic. You get full access to the configuration of PHP, MySQL/MariaDB, Redis, and caching mechanisms - without any restrictions imposed by other types of hosting and virtualization.

 

How can I ensure the security of a dedicated server?

You need to set up a set of protective mechanisms, such as: firewall (nftables, iptables, or ufw), SSH key access, regular system updates, Fail2ban for brute force protection, resource monitoring, and logging. It is also advisable to set up backups, system integrity checks, and restrict access rights for services. When configured correctly, a dedicated server can achieve a very high level of security.

 

What to choose, a dedicated or cloud server?

A dedicated server provides maximum performance, stability, and physical isolation. A cloud server wins in terms of flexibility, speed of scaling, and automation. If absolute predictability and high-load operation are important for your project, then it is better to choose a dedicated server. If periodic dynamic scaling is required, then the cloud is more often chosen.

 

Can a dedicated server handle peak loads?

Yes. Thanks to dedicated hardware resources, the absence of neighboring projects, and the ability to optimize the configuration for a specific load, the server can consistently withstand sudden spikes in traffic. Additionally, you can configure caching, CDN, and load balancing to increase system stability.

 

 

 

Conclusion

In summary, a dedicated server is a reliable, productive, and flexible solution that provides complete control over the infrastructure, a high level of security, and stable operation of resource-intensive projects. Despite its higher cost compared to virtual solutions, a dedicated server is a worthwhile investment for businesses that require predictability, speed, and stability.

This approach allows you to create an IT infrastructure that can scale with your project and withstand even extreme loads. And we haven't even discussed GPU servers yet :)
