With Eucalyptus, we anticipate that we will see an immediate return-on-investment without losing any of the public cloud benefits. May 16, 2011 Eucalyptus Systems, creators of the most widely deployed on-premise cloud infrastructure-as-a-service (IaaS) platform, today announced that Plinga , one of the leading social games publishers in Europe, has selected Eucalyptus for its private cloud computing software. Plinga currently hosts more than 30 social games across 20 social networks and game portals in Europe, including six of the top 20 most popular games in Germany and five of the top 10 games in Poland. Eucalyptus provides Plinga with a dynamically scalable, highly available, elastic and agile software for managing its rapidly growing social games using secure, on-premise IT compute and storage resources. Plinga is quickly becoming a major player in the gaming industry. Its games like the popular Icy Tower' and Pet Party' are experiencing extremely high growth, increasing its need for a dynamically scalable yet cost-effective IT infrastructure, said Marten Mickos, Eucalyptus Systems CEO. With over 25,000 Eucalyptus clouds having been started up, Plinga has chosen the world's most widely deployed private IaaS cloud platform, and we look forward to working with them as part of their continued success. From its inception, Plinga has embraced cloud computing for on-demand compute resources that can scale up and down to meet the traffic demands of its social games. While Plinga initially used the Amazon Web Services (AWS) public cloud infrastructure, the company is now moving to a cost-effective, on-premise Eucalyptus cloud environment that can provide elastic scaling with complete IT control. Because Eucalyptus is directly compatible with Amazon EC2 APIs and image formats, Plinga can seamlessly migrate to and from the public cloud for maximum flexibility and cost savings. Eucalyptus provides integrated methods to manage rapid scale-up and scale-down of new and popular games and the stability and cost-effectiveness for mature games, said Thorsten Lubinski, Plinga CTO. With Eucalyptus, we anticipate that we will see an immediate return-on-investment without losing any of the public cloud benefits.
