Summary
In this chapter, we looked at the basic concepts of IIoT data processing. First, we explored the concept of microservices versus a monolithic application. We studied Docker and how it can help us deploy microservices-based architectures. In the upcoming chapters, we will make extensive use of Docker to simplify deployment.
We learned about the key principles of data storage, including time series, asset management using asset registry, and data processing with advanced analytics. Finally, we implemented our first end-to-end IoT flow with InfluxDB, Node-RED, and OPC-UA.
In the next chapter, we will build a real IIoT solution based on common open source technologies.
