This week, Piston Cloud Computing announced the finalization of $8 million in Series B funding from Cisco Systems, Data Collective and Swisscom Ventures, with additional participation from Divergent Ventures, Hummer Winblad and True Ventures. The $8 million in Series B funding builds upon $4.5 million in Series A funding from July 2011. The funding will be used to accelerate Piston’s product development and enhance the company’s ability to respond to the needs of its expanding product base. Piston recently appointed open source industry veteran Jim Morrisroe as CEO and correspondingly freed up Joshua McKenty, the company’s founding CEO, to focus on product development for Piston and his responsibilities as a board member of the OpenStack Foundation. Piston claims a unique and powerful position in the commercial OpenStack space given the depth of its executive experience in OpenStack and commercial open-source software. The company delivers software for managing private clouds based on OpenStack Infrastructure as a Service technology. Piston Enterprise OpenStack leverages its proprietary Moxie High Availability platform to minimize service disruptions and Null-Tier Architecture to simplify scaling and overall infrastructure management. Piston’s core product boasts the ability to operationalize an OpenStack private cloud in less than 10 minutes.
