This document summarizes a presentation on key challenges in cloud computing to enable the future Internet of Things. The presentation discusses: 1) An architectural view of IoT over clouds, including instrumentation, interconnection, communication, intelligence, and processing layers. 2) Challenges in cloud computing to support IoT requirements like elasticity, quality of service, scalability, reliability, security, and energy efficiency. Research lines are proposed to address these challenges. 3) Maximizing the value of joint EU-Japan research efforts through openness, standardization, collaboration, and re-use; and leveraging ongoing EU research projects and open-source tools.
