Are the Resources (RAM, CPU, HDD) Guaranteed on a Dedicated Server?

When it comes to dedicated servers, the resources such as RAM, CPU, and HDD are typically guaranteed.

Unlike shared hosting, where multiple users share the same resources, a dedicated server offers exclusive access to these components. This ensures that the allocated resources are solely dedicated to your server, providing enhanced performance and reliability.

RAM: On a dedicated server, the amount of RAM specified in your hosting plan is guaranteed for your exclusive use. This allows you to run memory-intensive applications smoothly without worrying about performance issues caused by insufficient memory.

CPU: The CPU resources on a dedicated server are also guaranteed. You have access to the full processing power of the CPU, enabling you to handle demanding tasks and high traffic volumes efficiently.

HDD: The dedicated server’s hard disk drive (HDD) is exclusively allocated to your server, ensuring that you have the entire storage capacity at your disposal. This allows you to store large amounts of data and run resource-intensive applications without any storage limitations.

In Linux, you can use various commands to monitor and manage these resources. For example, to check RAM usage, you can use the free command. To monitor CPU usage, you can utilize the top command. Additionally, the df command helps you view HDD usage and available disk space.

How to Access a Linux Server (SSH)

SSH (Secure Shell) is a secure protocol used to access and manage remote Linux servers. It provides a secure encrypted connection between the client and the server, ensuring data confidentiality and integrity. Here’s how you can access a Linux server using SSH:

1. Open a terminal on your local machine running Linux OS.
2. Use the ssh command followed by the username and IP address of the server you want to connect to. For example: ssh username@192.168.0.1.
3. If it’s your first time connecting to the server, you may be prompted to verify the server’s fingerprint. Type yes to continue.
4. Enter the password for the user account you specified. Note that the password won’t be visible as you type it.
5. Once authenticated, you will have access to the server’s command line interface. You can now execute commands and manage the server remotely.

To enhance security, it’s recommended to use SSH key-based authentication instead of passwords. This involves generating a public-private key pair on your local machine and adding the public key to the server’s authorized keys file.

Accessing a Linux server via SSH provides a convenient and secure way to manage your server remotely, allowing you to perform various administrative tasks efficiently. 😊
