1. Tussle OS – an idea that has met its Waterloo Jon Crowcroft, http://www.cl.cam.ac.uk/~jac22 With help from Keshav & Rayman

2. Isolation Red & Black The user’s apps v. The utility co.’s apps Same data Well, different granularity… Perhaps different lifetimes E.g. optimising home v. optimising bill

3. Latency Home is where the applications run Why go out over net & back? Why send other than occasional summaries to utility co? Need external access into the home For on the move control/alerts… Easy (same as skype ) Just NAT traversal

4. Availability Soups – home/mobile user need 6-fold replication to get 5 9s availability Equivalent to EC2 or mirror in Big Cloud Big Cloud expensive In energy/data center cooling Cheaper in ops/management

5. Energy Of energy By energy For energy And water, and gas, and internet, transportation, etc etc

6. Parsimony Unikernels v. Containers Irmin Block chain Reputational&Currency The “Hourglass Model”, Steve Deering Uk Many different kinds of applications and Users Many different kinds of Utilities

7. Next … Hub-of-all-things – IoT centric Monetize your data Data aggregators Apps - analytics User Centric Networking – Personal information hub Value your opinion Entertainment/Well-being Apps - recommenders
