When we look at the systems that are being built within the IoT from a bigger picture, they include physical devices, communication gateways and data centres. In this post, I’ll talk about Edge, Fog and Cloud Computing and where the use of DDS🌀 technology is most beneficial. Data in IIoT system needs to be efficiently…
When you are creating a distributed event driven system, you have to carefully think about observability. It is because such systems are more complex due to their asynchronous nature. ThereforeThere is less control over the processing flows. It is more difficult to test and debug. This requires to think carefully about observability infrastructure with providing…
There are cases where no matter what you do, DDS applications do not want to communicate with each other. In this post and video, I’ll share with you 4 reasons why DDS applications don’t communicate with each other and how you can verify and resolve the issue. Firewall First, make sure your communication is not…
EDA – All you need to know Real-world systems often rely on distributed software systems. That’s why it is crucial to establish the interconnectivity and interoperability between these systems. It’s now getting more common for system designs to be built on event-driven architecture. Why? Because this is the way to enable efficient, real-time communication between…
In the second part of the series, we will focus on the assembly of all components. There are not many parts to assembly, and the assembly itself is easy. We just need to pay attention to a few things. The following guide was inspired from the Pycom documentation and, if necessary, it is possible to…
I find out about Pycom company, which created LoPy, from a Kickstarter campaign. This company had had an experience with the first generation of WiPy at that time already. And because at that time I was (and I still am) very interested about everything about IoT, I could not resist the temptation to try something new,…
We can see a growth in numbers of IoT platforms. It does exist hundreds of IoT platforms (about 400 according to iot-analytics in Q1 2017). Among platforms, which provide the most comprehensive services belongs platform Watson IoT from IBM, platform ThingWorx from PTC, platform Azure IoT from Microsoft, platform AWS IoT from Amazon and platform Predix from GE. Among the main watched categories of IoT platforms belong…
There are many standards, consortiums and alliances concerning Internet of Things and the number will grow. Here is stated the most complete list on March 2016. In my opinion, the most promising standard for Industrial Internet of Thing is DDS and most promising consortiums are Industrial Internet Consortium and Open Fog Consortium. Source: How does W3C…
WiFi and ZigBee have limited range, and cellular can be too expensive and power hungry. So numerous alternatives for Low Power Wide Area Networking (LPWAN) have arisen to serve the needs of the Internet of Things (IoT). These alternatives include especially LoRaWAN, Sigfox a Weightless.

The Data Distribution Service (DDS™) is a middleware protocol and API standard for data-centric connectivity from the Object Management Group® (OMG®). It integrates the components of a system together, providing low-latency data connectivity, extreme reliability, and a scalable architecture that business and mission-critical Internet of Things (IoT) applications need.
