• IoT = Internet of Things. Really?

• It means "all things can communicate via Internet"

• It means "all things have communication module (Wifi, Bluetooth)"

What is the Big Data

• Big Data = Big + Data + Distributed Computing + Analysis

• Input of Big Data = Various and Massive Data

• Output of Big Data = Insights (also called "Value")

We already know

Why IoT need Big Data (1)

• Things = Devices (Rasberry Pi, Arduino, ...) with various sensor

• Devices grep a lot of data from sensors

• Temperature, Air Quality, Movements, GPS, Pressure, Images, ...

• Devices have to store the data somewhere else

Why IoT need Big Data (2)

• IoT data also have to be analyzed

• Massive data analysis are needed for getting insights

• Realtime analysis is also needed for instantaneous

• Big data do it

Device ➞ Big Data Analysis ➞ Insights
