With an ever-increasing number of companies now buying computing, storage, and networking power as they need it from the cloud, it is hardly surprising that SYS-CON's industry-leading International Cloud Computing Conference & Expo series is going from strength to strength.

Now held three times a year, in New York, Prague, and Silicon Valley, the organizing principle of each International Cloud Computing Conference & Expo remains the same: our aim is to ensure, through an intense and carefully chosen program of technical and strategic breakout sessions, that attending delegates leave each Conference with abundant resources, ideas and examples they can apply immediately to leveraging the Cloud, helping them to maximize performance, minimize cost and improve the scalability of their Enterprise IT endeavors.

The Call for Papers for the 4th International Cloud Computing Conference & Expo, which will be held at the Santa Clara Convention Center in Santa Clara, CA, on November 2- 4, 2009, is closing shortly. The Conference Theme in Santa Clara is "Bringing the Economics of the Web to Enterprise IT Through Cloud Computing."

Our aim with each conference is to showcase breakout sessions from members of every layer of the Cloud ecosystem. The submission process is 100% online and the submissions URL is here. (Closing date July 15, 2009.)
