Outline

• User Generated Contents• From Consumer to Prosumer

• User Generated Services (UGS)

• User Provided Services (UPS)

• Webinos: A cloud platform to support UGS and UPS

• Enabled scenarios

• Conclusions

User Generated Contents• Spread of Social networks, blogs

• Producer – Consumer (ProSumer)

User Generated Services• Public APIs (google maps, twitter, …)

• High level tools• IFTTT (if this then that)• Yahoo Pipes

• Future Prospects• Users will able to create and provide on-the-fly

services using their devices• Markets for services: Pay for using services, not for

applications.

If this then that !

Yahoo Pipes

User Provided Services• About 7 connected devices per person in 2020• Services will be provided by users through their devices

• Google Latitude • Il Meteo (www.ilmeteo.it)

• Social networks of service providers

Webinos (www.webinos.org)

The webinos project will define and deliver an Open Source Platform and software components for the Future Internet in the form of web runtime extensions, to enable web applications and services to be used and shared consistently and securely over a broad spectrum of converged and connected devices, including mobile, PC, home media (TV) and in-car units.

webinos: Cloud Architecture

• Private/Shared cloud• Personal Zone

• Personal Zone Proxy

• Device specific API• Filesystem• Geolocation• Messaging• …

• Personal Zone Hub

Ex: webinos.discovery.findService(“http://webinos.org/api/filesystem”, findCallback)

Comparison with other platforms 1/2LocationManager locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);

• 1 Device involved• App and locManager are in the same

device

• Alices_car.location.getCurrentPosition(callback)

• N devices involved• Each API could be used as

a service

Comparison with other platforms 2/2

• Common cloud platforms provide mainly data synchronization among devices• Multimedia, Documents, Contacts, …

• webinos enables sharing of features among devices.• Devices may own to different users

Why webinos for UGS and UPS?• APIs to deal with device specific capabilities (filesystem,

messaging,geolocation,…)

• Each capability can be seen as a service provided by a device.

• Webinos provides both the mechanism for dynamic registration of new services and discovery of services and data within its Cloud infrastructures.

• Access control and data handling policies management

• Applications are able to communicate with other applications which reside on different devices
