The document discusses infrastructure interoperability challenges in cloud environments, particularly focusing on virtual networks and their definitions. It highlights the lack of a vendor-neutral standard that can accommodate large-scale deployments and the need for features like strong isolation and easy management. The Open Cloud Consortium is working on developing an open specification for virtual networks and testing implementations to address these issues.
