The Parallels Plesk Panel (ex: Parallels Plesk Control Panel, Plesk Server Administrator, PSA,[citation needed] or just Plesk) software package is a commercial web hosting automation program. Originally released under the U.S. company Plesk Inc. and designed in Novosibirsk, Russia, Plesk was acquired by SWSoft in July 2003. SWSoft would rename themselves under the Parallels name (a brand which had been acquired by SWSoft) in 2008. Parallels Plesk Panel allows a server administrator to set up new websites, reseller accounts, e-mail accounts, and DNS entries through a web-based interface. The administrator can create client and site templates, which predetermine resource-allocation parameters for the domains and/or clients.  Parallels Plesk Panel for Linux/UNIX supports multiple POSIX platforms, including Debian, Fedora, FreeBSD, Red Hat Linux, SUSE and Ubuntu. Parallels Plesk Panel for Windows supports Windows Server 2003 and Windows Server 2008 operating systems.  Parallels Plesk Panel installs custom versions of or manages versions of MySQL and PostgreSQL databases (Microsoft SQL Server and Microsoft SQL Server Desktop Engine under Windows), Apache Tomcat Java platform server, ColdFusion server, as well as CounterStrike and Battlefield 1942 game servers.
