From the examples we have looked at in the previous chapter, we have seen how IoT helps us achieve a world of connected devices. But is that all there is to IoT? Well, no. The world of connected devices is step zero in the process of human evolution.

In a few years from now, IoT will be as integral as the internet itself.

Having a world of connected devices is all about convenience in terms of the ability to monitor and manage these devices remotely. Next comes the world of smart devices. Smart devices are the next generation of IoT, where the devices not only talk to a centralized entity, such as the cloud, but also talk to each other, keeping you in the loop.

Taking a smart home scenario, take a look at the following WhatsApp group chat for Arvind's Home:

In my humble opinion, IoT, and healthcare are match made in heaven. The value that comes from integrating seamless connectivity and smartness between living beings and their health is priceless.

Things such as postoperative care, elderly monitoring, and remote diabetes monitoring are only a few areas of impact.

Before we proceed further, I would recommend you to watch this video, Scott Hanselman's best demo! IoT, Azure, Machine Learning & more at https://www.youtube.com/watch?v=u5oTz1e5qqE to understand the true power of real-time healthcare.

In 2018, we are defining smart healthcare, but the sad truth is that something as trivial as healthcare and its intelligence component should have been the primary focus from the beginning.

As a side note, if you want to see how these disruptive technologies might turn out from the eyes of Charlie Brooker (http...

Industrial IoT or, as it's more popularly known, IIoT, is one of the key impact areas of IoT. With the power of industrial sensors, as well as a world of smart devices, we can achieve and automate a lot more.

The following diagram is from an article by Greg Cline on Industry 4.0 and Industrial IoT in Manufacturing: A Sneak Peek, at http://www.aberdeenessentials.com/opspro-essentials/industry-4-0-industrial-iot-manufacturing-sneak-peek/:

As we can see from the diagram, we are currently in the era of industry 4.0, where, with the power of smart devices, we could change the way a manufacturing process runs.

Take a look the following videos to get a better idea as to what industry 4.0 is all about:

• Industry 4.0 in the Volkswagen Group (Volkswagen): https:/...

In this chapter, we have dwelled on the world of healthcare and industry. Now, at a high level, let's take a look at other potential areas of impact.

Smart agriculture is all about finding optimal farming methodologies to increase the final yield, as well as to preserve natural resources. This is more beneficial to commercial farmers than anybody else.

Crops that yield cotton, cocoa, sugar, oranges, and so on would have a greater impact on the ability of smart and controlled farming.

Greenhouses can also benefit from the technologies of smart farming.

Here is an overview of this domain:

In this chapter, we have gone through various domains where IoT can add value. We have specifically dwelled on the healthcare and industry domains. Next, we looked at other possible domains that could be impacted by IoT.

In the next few chapters, we are going to look at various IoT platforms that can bring the previous visions to reality.
