The Internet of Things (IoT) begins with sources of data or devices that perform an action. These we call endpoints, and they are the things associated with the internet. When one discusses IoT, in general, the actual sources of data are often overlooked. These sources are sensors outputting a stream of time-correlated data that must be transmitted securely, possibly analyzed, and possibly stored. The value of IoT is in the data in aggregate. Therefore, the data a sensor provides is crucial. However, for an architect, it is critical to understand the data as well as how the data is interpreted. Besides understanding what data is collected and how it is acquired, in a massive IoT deployment, it is useful to know what can be sensed, and what the constraints are for various sensors. For example, a system must account for lost devices and erroneous data. An architect must understand the reasons why data may not be reliable from sensors, and how...

Overview of this book
The Internet of Things (IoT) is the fastest growing technology market. Industries are embracing IoT technologies to improve operational expenses, product life, and people's well-being.
We’ll begin our journey with an introduction to Raspberry Pi and quickly jump right into Python programming. We’ll learn all concepts through multiple projects, and then reinforce our learnings by creating an IoT robot car. We’ll examine modern sensor systems and focus on what their power and functionality can bring to our system. We’ll also gain insight into cloud and fog architectures, including the OpenFog standards. The Learning Path will conclude by discussing three forms of prevalent attacks and ways to improve the security of our IoT infrastructure.
By the end of this Learning Path, we will have traversed the entire spectrum of technologies needed to build a successful IoT system, and will have the confidence to build, secure, and monitor our IoT infrastructure.
This Learning Path includes content from the following Packt products:
