Design Patterns

for IoT

Chapter

3

Design Patterns are an effective way of solving

common repetitive problems in various

domains. If we want to understand this better,

let’s take a very common “Road Traffic” problem

faced by all the countries in the world. As you

know, every country is very diverse in terms of

political and environmental scenarios. So find-

ing a common solution would be very tricky.

However, we could think of a solution, which is

applicable to small or negligible changes. That’s

the aim of creating a design pattern. Now, what

could be the solution? There are three design

patterns we see every day, traffic lights, stop sign

and roundabout. All these three design patterns

solve or help to control traffic. Although, they

have their own advantages, disadvantages, and

use cases based on contextual factors. As you

can see, design patterns help in building end-to-

end solutions, which can be used to architect the

desired system. Please do not misunderstand the

design pattern as a complete solution. You can

consider a design pattern as a template to build a

concrete solution for your specific purpose.

Working with design patterns for IoT

(internet of things) applications is a lot more

different than the traditional software appli-

cations. Devices in the IoT ecosystem can use

separate networks to establish connections,

which is quite opposed to the conventional

software architectures. Design patterns in IoT

differ in terms of their abstraction and level of

detail. Thus, to create user-friendly and robust

IoT applications, it is necessary to consider IoT

design patterns for several layers.

The procedures for configuration manage-

ment, deployment, and automated provisioning

pertaining to the IoT edge applications, which

are explained in this chapter, are associated with

the design patterns for governance.

The idea to configure systems and connect

devices is quite complex. IoT design patterns

address concerns related to the management of

edge applications from initialization to deploy-

ment. To create IoT-based applications, consider

the following design patterns to generate the best

possible results.

After completing this chapter, you will be able to:

• Understand various design patterns of IoT

• Understand the difference between traditional and IoT design patterns

• Learn challenges for selecting a specific design patterns

• Learn strategies to overcome challenges to implement chosen design

patterns, and

• Tools needed to implement design patterns.
