Comprehensive Guide to Using a Virtual Server / How to Use a VPS?

Today, with the growth of digital services, website design, application development, and the execution of web-based projects, the use of Virtual Private Servers (VPS) and working with VPS has become a common choice for developers, startups, and even professional home users.

But for many novice users, the question arises: “What is a Virtual Private Server and how can it be used?”

In this article, we intend to explain, step-by-step, clearly and practically, what a Virtual Private Server is, what its applications are, and how to use a Virtual Private Server.

What is a Virtual Private Server (VPS)?

Virtual Private Server or VPS is a type of hosting that consists of dividing a physical server into several separate sections. Each user has access to a dedicated portion of resources (RAM, CPU, storage space) and can manage it like a dedicated server.

Difference Between VPS, Shared Hosting, and Dedicated Server:

Common Uses of Virtual Private Server and Working with VPS

Due to its flexibility, dedicated resources, and full server access, a Virtual Private Server (VPS) is considered an ideal solution for many online projects. Below, we will explore the common and important uses of VPS:

1. Hosting Dynamic and Professional Websites

Using a virtual server to host sites that require high performance, such as:

• High-traffic WordPress websites
• Content Management Systems like Joomla and Drupal
• PHP projects based on Laravel
• Python applications with the Django framework

VPS provides complete freedom to configure the appropriate environment, install plugins, and manage resources.

2. Running Dedicated Applications and Custom Projects

If you have an application that requires installing libraries, configuring ports, or running specific services, using a Virtual Server is the best choice.
Suitable for:

• Node.js apps
• Dedicated APIs
• Web-based management panels

3. Setting up a Dedicated Email Server

For companies that value security, control, and branding, using a Virtual Server allows them to create their own dedicated email server.

Advantages:

• Using a dedicated domain (e.g., info@yourdomain.com)
• No dependency on public services like Gmail
• Control over spam, filters, encryption, and backups

4. Professional Database Hosting

Using a Virtual Server, you can install various types of databases on the server:

• MySQL / MariaDB for WordPress or PHP projects
• PostgreSQL for enterprise applications
• MongoDB for NoSQL and real-time apps

5. Running a Telegram Bot or Node.js Applications

Many Telegram bots or real-time applications that require continuous execution and constant connection can only be hosted on a VPS. Using a Virtual Server provides full access to ports and the installation of custom modules.

6. Using as a Backup Server and Data Storage

VPS is a reliable and cost-effective option for storing backup files. You can:

• Automatically back up your website or database.
• Encrypt and archive files.
• Have secure remote access.

7. Remote Desktop Connection for Commercial Use

Users can set up Remote Desktop (RDP) on a Windows VPS server and use it for:

• Project management
• Performing administrative tasks remotely
• Running software that requires a permanent connection.
  

8. Running a Game Server or Live Stream Server

If you intend to set up a game server or have a stable and dedicated environment for live video streaming, using a VPS is an excellent option. Suitable for:

• Minecraft, CS:GO, ARK, and other game servers
• Setting up streaming platforms like Owncast or Nginx RTMP

Steps to Use a Virtual Server

1. Selecting and Purchasing a Virtual Server

First, you need to purchase a virtual server from a reputable provider. When purchasing, pay attention to the following:

• Geographic location of the data center (Iran or abroad)
  
• Operating system type (Linux or Windows)
  
• Amount of hardware resources required (RAM, CPU, Disk)
  
• Security features and technical support
  

2. Receiving Server Login Information

After purchasing, the following information will be sent to you to use the virtual server:

• Server IP address
  
• Username (usually root on Linux or Administrator on Windows)
  
• Initial password
  
• Installed Operating System
  

3. Connecting to the Virtual Server

 For Windows Operating System (RDP):

Use the Remote Desktop Connection tool:

1. In the Start menu, type: Remote Desktop Connection
   
2. Enter the server’s IP address
   
3. Enter the username and password
   
4. After connecting, you will be faced with the server’s desktop environment
   

 For Linux Server (SSH):

On Linux or macOS operating systems, use the terminal. On Windows, use programs like PuTTY or Termius.

ssh root@your-server-ip

Upon the initial connection, the system will display a security alert that you can confirm.

4. Initial Actions After Logging into the Server

After logging into the VPS, take the following steps to enhance security and efficiency:

 Change Password

passwd

 Firewall Activation

For Linux:

ufw enable

ufw allow 22

Operating System Update

apt update && apt upgrade -y     # For Ubuntu/Debian

yum update -y                    # For CentOS

5. Software Installation and Project Execution

Now that you have a virtual server, you can install any software you need. For example:

Installing Nginx and PHP on Ubuntu:

apt install nginx php php-fpm -y

Installing MySQL Database:

apt install mysql-server -y

Setting up a Website:

You can transfer website files to the server via SFTP or SCP and place them in the /var/www/ directory.

6. Using Control Panels for More Convenience

If you are not comfortable with the command line, you can use panels such as the following to manage your virtual server:

7. Server Care and Maintenance

To ensure the proper functioning of the server, check the following regularly:

• Resource Usage (using the htop or top command)
  
• Disk Space Usage (df -h)
  
• Security and System Logs (/var/log/)
  
• Automatic Backup Settings (Backup)
  

Conclusion

Using a Virtual Private Server gives you complete control, greater security, and high flexibility in managing online resources. By learning how to connect, install software, and perform initial configurations, you can easily run your projects on your own dedicated platform.

If you plan to pursue professional activities in the field of digital, web development, or application hosting, a VPS is one of the best choices to start your professional journey.

Frequently Asked Questions

1. Is the Virtual Server always on and accessible? “`

Yes. Your virtual server runs 24/7 in the host’s data center.
Unless you manually turn it off or the hosting company performs maintenance or updates, your VPS is always online and accessible.

2. Do I need to know programming to use a VPS?

Not necessarily. For basic usage, you don’t need in-depth programming knowledge.
However, for more professional server management—especially on unmanaged VPSs—familiarity with basic Linux commands or the Windows Server environment is helpful and sometimes essential.

If you are a beginner, you can use HiData’s managed VPS services to have all the settings and technical support done for you.

3. Can I host multiple websites on one VPS?

Yes, this is one of the key advantages of a virtual server.
You can manage multiple domains and sites on one VPS by installing control panels such as Cpanel, DirectAdmin, or CyberPanel. Even without a panel, it is possible to host multiple sites by configuring Virtual Hosts on web servers like Apache or Nginx.

4. Can a VPS be upgraded?

Yes. If your website traffic increases or you need more resources, you can usually upgrade your VPS plan to a version with more RAM, CPU, or disk space — without needing to transfer data to a new server.

5. What is the difference between VPS and shared hosting?

In shared hosting, server resources (such as RAM, CPU, and bandwidth) are shared with multiple other users. But in VPS, you have dedicated resources with full access to the operating system. This means much greater security, speed, and flexibility.
