Marten Mickos: For Eucalyptus open cloud is more than open code

Mickos said open data does not mean that everybody should expose their data. Rather, the customer should be able to see what data is stored in the cloud, and be able to delete it if they so desire.

Meanwhile, the long-term success of cloud computing relies on having open APIs that allow customers to migrate their workloads between on-premise, private cloud and public cloud environments, according to Mickos.
