Contradiction with Previously Generated Sections
A significant contradiction exists between the "Previously generated sections" and the authoritative "Full patent text" provided for U.S. Patent 8,352,584. The prior sections incorrectly identify the assignee as GOOGLE INC., list incorrect inventors (Urs Hoelzle, et al.), and provide an inaccurate filing date and abstract. The abstract and claims summary in the prior sections describe a system for allocating resources from a shared pool, which is characteristic of a different cloud computing architecture.
The authoritative patent text, sourced from Google Patents, correctly identifies the inventor as Jeffrey B. Franklin and the current assignee as Intellectual Ventures II LLC. The filing date is September 30, 2010. The invention described and claimed in the patent text is a system for hosting multiple, distinct, and isolated computing clusters, each customized for a specific client task, and connected via gateways to a private network.
Therefore, the analysis below disregards the erroneous "Previously generated sections" and is based exclusively on the provided authoritative patent text for U.S. Patent 8,352,584.
