Introduction to MQTT protocol for IOT applications.

In my previous blog post, I explained why the widely used application-layer protocol HTTP is not suitable for the IOT applications. There are a number of application-layer protocols developed to serve the purpose of IOT like MQTT, AMQP, CoAP, XMPP, STOMP etc. In this blog post, I will provide an introduction to MQTT protocol, its design, architecture and use-case examples.

Why HTTP is not suitable for IOT applications.

When developing modern web-applications, the most commonly used application layer protocol is HTTP. It is suitable for serving hypermedia resources in a request-response fashion over the internet. However, when it comes to the Internet of things(IOT), it tends to perform poorly mainly because it was designed to be a reliable but heavy-weight protocol for the world-wide-web. In this blog, I want to highlight the issues with HTTP with respect to IOT applications.

The Internet of Things is just getting started

The Internet of Things (IoT) is just getting started. Honestly though, if you think about it, IoT has always been here. In the beginning, we had the internet. Traditionally, the internet’s purpose was to allow devices to serve content from the internet. Now with IoT, we simply alter the paradigm and consider that the device is sending sensor data to the internet. In other words, we have always had the ability to do IoT, but what has changed is the notion around how devices and device data can be used.

Using IoT on a Beer Kegerator

Being born and raised in the great state of Wisconsin, beer has been a part of most of my adult life. Couple that with my love of technology, I always wondered how I could leverage some cool tech with a beer theme. Since the proliferation of inexpensive hardware and the Internet of Things (IoT), it has now become easy (and cheap!) to provide solutions that can be used to monitor (among other things) beer-related activities. This article will describe and detail the steps I took to create a solution for monitoring beer consumption on a beer kegerator.

IoT Device Security

IoT is a huge topic, especially for enterprises. Many have been doing it for years, and many more are interested in doing it for the first time. Companies like Target have proven that it is often these smaller and non-obvious machines that are being used to penetrate systems and cause havoc or steal information. Utilizing an air-gap or analog segregations only make manipulations more difficult to detect. Microsoft has created a very robust set of Azure services to mitigate any qualms about using their cloud services, but what about their connected devices? Could an infiltrator access these to penetrate the system, or modify their programming to cause malicious damage?
