Could you provide some guidance on the proper and efficient management of VPS/VDS? I have recently made the switch from traditional hosting to UPU and my knowledge in this area is limited.
For instance, should I install an antivirus and other features that are available?

To avoid hindering your learning, refrain from installing any ISP Manager / Vesta / cPanel as they use up valuable resources. Even Vesta, the lightest of the options, consumes a decent amount of resources, and it's unlikely you have a VPS with 8GB+ of memory.

Instead, learn through studying lessons, articles, manuals, and best practices for each package. Follow this approximate order:

- Deploy the axis
- Update immediately
- Create and configure swap
- Change the root password to something super-mega-complex (though we won't use it)
- Create a regular user with a password of normal complexity (this will be used for sudo)
- Grant the user sudo rights
- Tighten SSH security by changing the port, disallowing root and password login (only ssh keys), and allowing entry to only one of their new login
- Configure UFW (default deny, allow http, https, your custom ssh port). If you only log in from specific places (office, home), you can just allow ssh to those IP addresses.
- Set your time zone with sudo dpkg-reconfigure tzdata for easy-to-read logs
- Configure logrotate
- Set up logwatch
- Configure Postfix to send emails from the server and configure it to an external mailer like Mandril to avoid spam filters
- Set up fail2ban, then write extensions to monitor things like login attempts to WordPress admin panels and block them with fail2ban
- Install everything needed (Git, Nginx, HHVM, PHP5-FPM, MariaDB, Memcached/Redis, etc.)

Remember to regularly log in to the server and run apt-get update && apt-get dist-upgrade.

P.S. This applies to Ubuntu/Debian systems, though packages and commands may differ slightly for other systems.

It's also crucial to secure the server properly with measures like changing passwords, disallowing root and password login for SSH, and setting up fail2ban.

To enhance security, it is advisable to alter the default port for ssh and authorize access only by key while disabling password login.
Additionally, installing fail2ban can be helpful in preventing unauthorized access attempts.

When I first started administering a server, I realized that it's best to use a control panel to manage it. In my case, I opted for ISPmanager. Personally, I don't see the need to utilize the console for complete server administration because everything runs smoothly without consuming too many resources. It's my responsibility to tell you that finding comprehensive guides online can be difficult and frustrating, as issues may arise unexpectedly, causing you to become agitated. With ISPmanager in place, you don't need to worry and can sleep soundly.

Have you ever tried managing a server before? What control panels have you worked with?

VPS accounts from hostingsource.com and asvhost.com are worth trying due to their top-notch services.
All is good, nothing negative to say, support is very fast, all problems are solved in a very short time at a very affordable price. I recommend them without any reservation, go to them.
