Linux servers can provide a large range of services: mail, web, backup, cloud, source repository …

The access to the services from outside can be secured using a VPN with OpenVPN or Wireguard or via SSH tunnels and the server can be protected by its software firewall and security can be increased by integrating “Security Enhanced Linux” support.

The webserver connections can be encrypted using Let’s Encrypt SSL certificates (free) or using a paid certificate.

Backup of the server can be stored into the cloud (Wasabi or BlackBlaze) or to another server using rsync, Duplicati, or Borg

The server status can be constantly monitored with Zabbix and Icinga

DigitalOcean and Netsons provide professional VPS services with many features and options.
