IoT Architecture

Choices

FOUR-LAYER ARCHITECTURE

The first layer of the four-layer architecture deals with network things like actuators and sensors.

The second layer deals with the aggregation of sensor data and the data conversion. The third

layer is concerned with the preprocessing of the data by the edge IT systems. Lastly, the fourth

layer focuses on how data is managed, analyzed, and saved through conventional data centers.

Chapter

4

Today, IoT is used for a wide array of applications

in education, healthcare, manufacturing, finance,

retail, supply chain, and other industries. Thus, it

should come as no surprise that businesses are

aggressively integrating IoT solutions into their

existing infrastructures.

Deciding to use IoT is one thing; successfully

implementing it is a whole dierent ball game.

This is because there are several factors at play.

Therefore, it is necessary that you must have a

reliable architecture, which can help you to suc-

cessfully implement IoT applications. Following

are some of the types of IoT architecture.

After completing this chapter, you will be able to:

• Learn various architectural patterns for IoT

• Understand the difference between four layer-and seven-layer

architecture

• Learn about fog computing and its advantages,

• Learn open stack cloud architecture

• Learn about Hadoop and see how it is useful in IoT

• Understand problems with IoT Streaming Ingestion

• Learn how to manage bad data and firmware multicity

• Learn enhancing data in stream and processing data at scale, and

• Learn Pattern 2 (Batch-Oriented Data Transfer)
