Open source cloud computing took another giant leap forward with Piston Cloud Computing's September 27 announcement of the launch of pentOS™. pentOS marks one of the first enterprise grade versions of OpenStack, the open source cloud computing infrastructure that has gained the backing of 110 companies including AMD, Canonical, Cisco, Dell, Intel and Citrix. The deployment of pentOS underscores the emerging power of OpenStack as an increasingly competitive option to Infrastructure as a Service (IaaS) vendors such as Amazon Web Services and Rackspace. With pentOS, Piston joins Citrix Systems, Nebula and Dell in an elite group of vendors that commercialize the OpenStack platform. Piston marks one of the first live deployments of an enterprise grade level of OpenStack because Nebula's OpenStack-based appliance and Citrix's Project Olympus anticipate shipping in Q4 of this year.
With pentOS, Piston Cloud Computing leverages OpenStack's IaaS software and additionally provides enterprise-level security, scaling and customer support. Some of the key features of pentOS involve the following:
• Ease of scalability: patent pending Null-tier architecture allows enterprises to scale their cloud architecture by replicating individual servers, one at a time, instead of upgrading an entire ecosystem of different machines.
• An enterprise installation of CloudAudit, a tool that enables cloud providers such as Piston to provide details of security and performance to potential customers.
• Enterprise customers can use pentOS to build private clouds and inter-operate with public clouds built upon an OpenStack infrastructure.
Piston's announcement comes head on the heels of OpenStack's launch of Diablo, its latest software release since the Cactus release in April 2011. Diablo, the first upgrade to OpenStack released on a 6 month schedule, upgrades its existing Nova, Object Storage and Glance components. The Diablo release additionally features OpenStack Dashboard and KeyStone. OpenStack Dashboard gives users access to an interface to understand performance within their cloud deployments. OpenStack Keystone provides enhanced authentication and identity management functionality.
Founded by CEO Joshua McKenty, chief technical architect of the NASA Nebula Cloud Computing Platform, and Christopher MacGown in early 2011, San Francisco based Piston Cloud Computing is funded by Hummer Winblad and True Ventures. The company's deployment of an enterprise version of OpenStack significantly alters the horizon of cloud computing options available to enterprises that have particular concerns about vendor lock-in. Once deployed in General Availability mode, pentOS, Nebula and Project Olympus collectively promise to reconfigure the balance of cloud computing market share away from Amazon Web Services, Rackspace and Joyent, toward commercialized offerings of OpenStack that can deliver the portability increasingly demanded by enterprise CIOs.
