Knowledge Base

Today, reliable and high-performance server solutions are critical for businesses and individuals. Especially for websites, applications, and other online services, dedicated servers offer more control, security, and resources compared to shared hosting solutions. In this context, the CCX23 dedicated server model offered by Hetzner Online GmbH stands out as an attractive option that combines performance and price advantage. In this article, we will examine the features, advantages, and usage areas of the Hetzner CCX23 dedicated server in detail.

1. Introduction: Overview of Dedicated Servers

Dedicated servers are physical servers that are exclusively allocated for a customer's use. This gives the customer full control over server resources and eliminates the need to share performance with other users. Dedicated servers are ideal for applications such as high-traffic websites, resource-intensive applications, game servers, and database servers.

• Full Control: Full authority and customization options on the server.
• High Performance: Maximum performance for applications without shared resource issues.
• Enhanced Security: Reduced security risks by not sharing server resources with other users.
• Scalability: Ability to increase or decrease server resources according to needs.

2. Hetzner CCX23 Dedicated Server: Technical Specifications

2.1. Processor (CPU)

The Hetzner CCX23 server is generally equipped with an AMD Ryzen™ 5 3600 or similar processor. This processor has 6 cores and 12 threads and offers sufficient performance for applications that require high processing power. The base clock speed is usually around 3.6 GHz and can go up to 4.2 GHz with Turbo Boost.

Sample CPU Performance (Sysbench):

sysbench --test=cpu --cpu-max-prime=20000 --num-threads=12 run

2.2. Memory (RAM)

The CCX23 server usually comes with 32 GB of DDR4 RAM. This amount is sufficient for most applications and workloads. The memory speed is usually 2666 MHz or higher. A high amount of RAM is important for memory-intensive applications such as database servers, caching, and virtualization.

2.3. Storage

The Hetzner CCX23 server is usually offered with 2 x 480 GB or 2 x 960 GB SSD storage space. SSDs have much faster read and write speeds compared to traditional hard drives (HDDs), which allows applications to load and run faster. The storage configuration can be configured as RAID 1 (mirroring), which increases data security.

2.4. Network Connection

The CCX23 server typically has a 1 Gbit/s network connection. This ensures high-speed data transfer and low latency. Hetzner's network is considered one of the best in Europe and offers a reliable and stable connection.

Testing Network Speed (iperf3):

iperf3 -c server_ip_address -P 10 -t 60

2.5. Operating System

Hetzner offers a variety of operating system options, including Linux distributions (Ubuntu, Debian, CentOS, Fedora), Windows Server, and VMware ESXi. The choice of operating system depends on the requirements and preferences of your application.

3. Advantages of Hetzner CCX23

4. Use Cases of Hetzner CCX23

4.1. Web Hosting

Hetzner CCX23 is ideal for high-traffic websites and applications. A dedicated server ensures that websites load quickly and run smoothly.

4.2. Game Servers

The CCX23 can be used as a game server for popular online games. A dedicated server provides low latency and high performance, which offers a better gaming experience for players.

4.3. Database Servers

The CCX23 is suitable for database servers such as MySQL, PostgreSQL, or MongoDB. High amounts of RAM and fast storage ensure that databases run efficiently.

4.4. Virtualization

The CCX23 can be used to run virtual machines (VMs) on virtualization platforms such as VMware ESXi, Proxmox, or KVM. A dedicated server provides enough resources to run multiple VMs simultaneously.

4.5. Application Servers

CCX23 can be used as an application server for custom web applications, APIs, and other server-side applications. The dedicated server ensures that applications run quickly and reliably.

5. Hetzner CCX23 Server Setup and Configuration

5.1. Operating System Installation

Hetzner offers various operating system options for server installation. Operating system installation can be easily done through Hetzner's control panel.

1. Log in to the Hetzner control panel.
2. Go to the server management section.
3. Select the operating system installation option.
4. Choose the operating system you want and follow the installation instructions.

5.2. Firewall Configuration

It is important to configure a firewall to keep your server secure. Firewall tools such as UFW (Uncomplicated Firewall) or iptables can be used.

Basic Firewall Configuration with UFW (Ubuntu):

sudo ufw enable
sudo ufw default deny incoming
sudo ufw allow 22/tcp  # For SSH access
sudo ufw allow 80/tcp  # For HTTP access
sudo ufw allow 443/tcp # For HTTPS access
sudo ufw status

5.3. SSH Access

It is recommended to use SSH (Secure Shell) to securely access the server. SSH provides access to the server via an encrypted connection.

SSH Key-Based Authentication:

1. Create an SSH key pair on your local machine: ssh-keygen -t rsa -b 4096
2. Copy the generated public key (id_rsa.pub) to the server: ssh-copy-id username@server_ip_address
3. Edit the SSH configuration file (/etc/ssh/sshd_config) on the server and set PasswordAuthentication no.
4. Restart the SSH service: sudo systemctl restart sshd

6. Hetzner CCX23 Server Performance Monitoring and Optimization

6.1. Monitoring Resource Usage

Various tools can be used to monitor server performance, including top, htop, vmstat, and iotop.

Example: Using htop

sudo apt install htop
htop

6.2. Database Optimization

To improve the performance of database servers, it is important to optimize the database configuration. For example, you can optimize memory settings and caching settings by editing the my.cnf file for MySQL.

6.3. Web Server Optimization

Techniques such as caching, compression, and HTTP/2 can be used to improve the performance of web servers. For example, you can make websites load faster by making appropriate configuration settings for Apache or Nginx.
