The Plesk software package is a proprietary commercial web hosting automation solution by SWsoft. Most commonly found bundled (or available as an optional extra) with VPS and dedicated server packages provided by professional hosting service providers, Plesk provides a graphical web based interface which allows the user to configure the most common server management tasks. This allows administrators with only a limited knowledge of the server operating system to do basic tasks that would otherwise require a command prompt. Plesk allows a server administrator to set up new websites, email accounts, and DNS entries through a web-based interface. Like competing commercial packages, there is a strong emphasis on the provision of tools to allow management of multiple clients and the multiple domains that belong to them. The administrator can create client and site templates which predetermine resource allocation parameters for the domains and/or clients.
