One of the major concerns around cloud computing is lock-in but can open APIs solve this problem. Are they enough to create portability and interoperability between providers? Can Open APIs mean that a proprietary platform can be a friend to the open source world?
Do standards matter in the cloud, are they important or a pointless waste of time which is more likely to inhibit innovation rather than benefit it?
One of the hottest topics in cloud is security. But is much of the cloud security debate simply FUD or are there some real consequences of this change? How does cloud change traditional security models, can they they be re-used or is it back to the drawing board?
