[15min live stream] Why is telemetry the essence of IoT solutions?

During this live stream I explained why I consider telemetry to be the essence of any IoT solution. I hope you will find it interesting. Below you can find the diagram I presented during my stream: Telemetry Consider subscribing to my newsletter to get a notification about the next live stream!

The Internet of Things is all about the many-to-many communication.

There are three main benefits of using the MQTT protocol: Many-to-many communication. The Publisher is unaware of the Subscribers. MQTT helps to manage that chaos. Let’s break it down. Many-to-many communication is stimulating as it enables ecosystem capabilities. What do I mean by the IoT ecosystem? That is a dynamic group of loosely connected devices that can interact with each other to realize various business use cases. When we introduce a new device to this environment, it increases the overall value of that solution.

MQTT Topic structure

Introduction What can you tell about the monitored device and measured feature based on MQTT Topic? MQTT Topics are highly flexible and do not force any structure. We should wisely use that compelling feature. I saw companies struggling with MQTT because they lacked a standardized approach to the MQTT Topic definition. Every department/team used a different Topic structure leading to massive integration challenges. I created this guide to show how you can effectively organize the MQTT Topic structure following:

What must you know about the implementation of MQTT protocol at AWS Cloud?

MQTT is an OASIS standard messaging protocol for the Internet of Things (IoT). It is of the most popular protocols in the Internet of Things domain. AWS supports MQTT, which is the default communication method between devices and AWS IoT Core service. But there are some significant differences between the implementation of the MQTT protocol at AWS and the OASIS specification. QoS (Quality of Service) levels define the assurance for message delivery.

Approach to cost optimization.

Someone asked me for help in reducing the AWS IoT cost. That person provided the maximum yearly expense per device and asked how to achieve it. I could not give any hints based on that single piece of information. It looks like a common misunderstanding, so I decided to share my thoughts on this topic. Starting the conversation with “I can spend X USD per year” does not move the cost optimization exercise an inch further.

Leveraging the AWS IoT Device Registry to store the physical location of connected devices.

There are several ways to store the physical location of IoT devices. In the case of static gadgets (smart home appliances, for example), we can leverage the AWS IoT Thing Groups. Thing Group represents a logical subset of the fleet. We use Thing Groups in various scenarios, one of which is to describe the physical location of assets. We can send a no-one-home MQTT message to all devices in the hall group to switch them into the desired state.
