The Internet of Things (IoT) embeds technology into any physical thing to enable never-before-seen levels of connectivity. IoT is revolutionizing industries and creating many new market opportunities. Cloud services play an important role in enabling deployment of IoT solutions that minimize time to market — and that’s where AWS fits in.
In this article, we’ll discuss:

AWS IoT Things Graph
As it stands today, the IoT industry does not currently have a widely used and accepted standard by vendors on how IoT devices should connect to each other. This makes it hard for developers to understand how this can be achieved across multiple manufacturers when developing IoT applications. As a result, the AWS IoT Things Graph was launched. This service helps to simplify the process of visually understanding the connectivity between IoT devices and web services.  
The service allows you to develop IoT applications using a visual drag-and-drop interface that connects devices and services together making it easier to build and understand workflows across the solution. One example provided by AWS explains that “you can create a workflow that is triggered by a motion sensor that will automatically take a picture and send a text message.  IoT Things Graph coordinates the interaction between devices and services, including any necessary protocol translation or unit conversion.”

IoT Things Graph uses reusable, pre-built models each of which consists of a set of actions,  events, and states, which can also be considered at inputs, outputs, and attributes respectively. The pre-built models contain popular
