Cloud and IoT integration: data-oriented


• IoT devices send data to the Cloud

• app built on top of standardcloud facilities (VMs, storage, network)

• app makes use of stored (non-real time) IoT data

• indirect, IoT device-initiatedonly, retrieval of actuation commands

Cloud and IoT integration: application-specific


• app uses ad-hoc mechanisms to interact with IoTdevices

• no explicit interactions between Cloud components and IoT infrastructure

• static infrastructure deployment

Cloud and IoT integration:full thing “cloudification”


• IoT infrastructure as a natural extension of a datacenter

• well-defined Cloud API as a resource management interface

• separation of concernsbetween infrastructure and application (when needed)

• from Cloud to Fog/Edgecomputing

• device computation offloading

IoT-Cloud engine: Stack4Things


• an open source project helping administrators to manage IoT device fleetswithout caring about their physical location, their network configuration, their underlying hardware/software setup

• a Cloud-oriented horizontal solution providing IoT object virtualization, customization, and orchestration

Use case: MCS for Smart City services

#SmartMEas crowdfundinginitiative and experimental Smart City testbed

Example of a S4T-powered MCS app

• Pothole Detection and Mapping (PDM)– Android app + Cloud backend– Web portal

• MCS enhanced by the IoT-Cloud– runtime injection of code to

nodes for computation at the edge• (locally) querying Roads API to

actually anchor potential sites to the road


PDM web portal


• a taxonomy and model for MCS• relating MCS to IoT and edge computing• adapted IaaS framework for IoT to serve as a

service-oriented platform for MCS• instantiate / deploy custom code at runtime• offloading capabilities exercised through MCS

app
