Shonan Meeting Oct 14-17, 201227Summary
 Inter-cloud computing and networking are essential forachieving ‘lifeline’ or mission critical social services, andmust be based on appropriate global standards.
GICTF is contributing to the promotion and standardization of suchinter-cloud interface

 We should encourage open discussions forsocial aspects, such as legal and regulatory
issues around them.
