PaaS vendor Engine Yard announced record growth for 2011 marked by $28 million in revenue and over 2000 paying customers. The revenue growth rate of 58% and an over 50% increase in the number of customers in 2011 enabled Engine Yard to claim leadership in the PaaS space. Other highlights for 2011 included the acquisition of Orchestra and the launch of Engine Yard labs, which provides users with the opportunity to examine new features and functionality in a test environment. Engine Yard acquired Orchestra in August 2011 to form the basis of its Orchestra PHP Cloud for deploying and managing PHP based applications. Today, Engine Yard’s Orchestra PHP Cloud runs alongside its Ruby on Rails-based Engine Yard Cloud. Engine Yard’s Orchestra PHP Cloud celebrates a significant release later this month featuring increased configurability through APIs and higher performance due to optimized stack images, as well as superior auto-scaling. San Francisco-based Engine Yard is backed by Benchmark Capital, New Enterprise Associates and Amazon.com.
