Infrastructure as a Service(IaaS)

• Provides virtualized computing resources over the Internet• Amazon AWS– EC2, Microsoft Azure, Google Cloud

Platform as a Service(PaaS)

• Platform allowing customers to develop, run and manage Web applications

• Google App Engine

Storage as a Service(StaaS)

• An architecture model in which a provider provides digital storage on their own infrastructure

• Amazon AWS – S3, Google Storage

Software as a Service(SaaS)

• Software is licensed on a subscription basis• Blackboard

Sensor Event as Service(SEaaS)

• Sensor Cloud providers • Sensor Observation Service- 52North.org

Stage 1: Receive Data from Sensor 1 Stage 2: Central IIoT Server submits the received data and instructions

to Big Data Analyzer Stage 3: Big Data retrieves corresponding historical data from database

archives Stage 4: After computing Big Data Analysis submits the conditions to

the Central IIoT server. Stage 5: After evaluating the conditions, the central server submits the

command to Actor 2. Stage 6: Sensor 3 submits the observations on Actor 2 actions for the

previous command.
