The ODCA (Open Data Center Alliance) -- whose membership roster includes BMW, Deutsche Bank, JPMorgan Chase, and Lockheed Martin -- has expanded its vision for how cloud services should work, with requirements for more cloud-friendly licensing and better mechanisms for access control. The advantages of public cloud services are evident to most CIOs. The hope is that the cloud's multitenant, shared infrastructure will enable greater flexibility and lower costs, according to the ODCA.
