Compared to realtime IoT patterns that provide end users with data instantaneously, on-demand patterns provide end users with data only when it’s requested. IoT applications built using this pattern get information by directly accessing the device or by getting it from a pre-stored location. On-demand patterns are useful when your application is not actively looking for data and only accesses it when needed.

In this chapter, you are going to build an example of this pattern, called a smarter parking system . Figure 7-1 shows a high-level diagram of all components ...
