The Open Data Center Alliance (ODCA) has announced the availability of five new usage models focused on security and infrastructure, and an overview document on identity management in the cloud. These user-driven requirements are based on the most pressing cloud computing challenges faced by member organizations says the alliance.

Four of the usage models and an overview document target security, a leading concern for cloud adoption. The security usage models will drive interoperability between identity management and access management systems that will allow users to utilize resources in the cloud as if they were located within the organization. The fifth usage model focuses on long distance virtual machine migration which provides information about enterprises’ expectations for availability, scalability and extendibility of their data via seamless data migration.
