Applications that have been implemented on legacy systems will migrate to cloud systems under the paradigm shift from “owning” to “leasing” IT.

  However, if each single system (hereafter a “single cloud”) is to provide a highly reliable system on a continuous basis, it must have high redundancy.

  To solve this problem, it is important to develop an inter-cloud world, in which multiple cloud systems running with different policies interwork with each other to share resources so that SLAs to users can be maintained even in the event of large fluctuations in the computing load that cannot be handled by a single cloud system. In order to promote interworking between international cloud systems, we will establish the Global Inter-Cloud Technology Forum, an organization aimed at bringing together the knowledge of industry, academia and government, and supporting R&D and feasibility tests on the technologies related to interworking between cloud systems.
