Dr. Joseph Reger from Fujitsu Siemens Computers discusses how social networking and online communities can benefit businesses through crowdsourcing and making information sharing more efficient. While public clouds present issues like security and reliability for enterprises, customized private or hybrid clouds can optimize costs through flexibility and dynamic scaling. Fujitsu Siemens aims to help customers build dynamic IT infrastructures through products, solutions, and managed services that leverage economies of scale from shared resources. They will showcase these offerings focused on dynamic infrastructures and green IT technologies at their booth and the BITKOM Green IT exhibit at CeBIT 2009.
