What is "plesk"

Plesk is a commercial web hosting platform. Originally released under the U.S. company Plesk Inc. and designed in Novosibirsk, Russia, Plesk was acquired by SWSoft in July 2003. SWSoft renamed themselves under the Parallels name (a brand which had been acquired by SWSoft) in 2008. In 2015 Parallels rebranded the service provider business unit to Odin. In December 2015 the Odin brand was acquired by Ingram Micro rendering Plesk a separate business entity.
