The universal answer to home service delivery these days seems to be "the cloud", even though nobody really agrees on what "cloud services" means. In order to bring some transparency to the Cloud, we identify what are the challenges in digital home services delivery, discuss the strengths and limitations of a pure cloud approach, and finally propose an hybrid solution relying both on data centers and home devices to better serve home users. We discuss the research and technology challenges that have to be solved to deploy this digital service delivery architecture.


 Christophe Diot received a Ph.D. degree in Computer Science from INP Grenoble in 1991. With INRIA Sophia-Antipolis (Oct 93-Sept 98), Diot pioneered diffserv, single source multicast, and peer-to-peer online games. At Sprint (Oct 98-Apr 03), he pioneered Internet measurements. Diot was with Intel Research from May 03 to Sept 05, and then joined Thomson where he started two research labs: Paris in 2006 and Palo Alto in 2011. Diot's research activities now focus on content delivery architectures and personalization. Diot has around 20 patents and more than 300 publications in major conferences and journals. Thomson became Technicolor in 10. Diot is currently Chief Scientist at Technicolor. He is an ACM fellow..
