Overview (CPaaS / CIaaS)

ClouT Reference Architecture - October 2014

City Platform as a Service (CPaaS)

Development and processing tools

City Infrastructure as a Service (CIaaS)

Exploiting computing and sensing resources available to the City

City Software as a Service (CSaaS)

Outside the architecture: applications developed on ClouT

City Infrastructure as a Service (CIaaS)

The IoT Kernel comprises all the IoT resources available to the City
The Sensorisation and Actuatorisation component is responsible for the “sensorisation” of legacy devices, rendering such resources IoT-compliant sensors and/or actuators
The Interoperability & City Resource Virtualisation component is in charge of validating and converting data gathered from both IoT and sensorised devices
The Computing and Storage offers all the physical and virtualized computing, networking and storage resources that are required to store, retrieve and elaborate city data
The City Infrastructure Management offers centralized search capabilities and event management on the discovered city resources

The City Resource Access offers the middleware software that enables the storing and retrieval of the collected city data, together with the associated metadata
The City Data Processing component enables the analysis and extraction of the data archived inside the cloud storage. It offers querying interfaces that are exposed to the overlaying services
The City Service Composition is both for technically oriented and un-experienced users to mash-up and aggregate data and services offered by deployed applications

Provides services for all the architectural modules
CSaaS applications can leverage A.A.A. facilities or use their autonomous security modules (and federate)
Dependability block monitors all the resources hardware and software
Encryption facilities are provided
