What is the specific situation for using Node-RED in the cloud?

Let's revisit the situation where Node-RED is used in the cloud.

As we mentioned in the previous chapter, Node-RED is both a tool and an execution environment for creating Node.js applications written in Node.js. As a reason to build an application with Node-RED, I explained that by black boxing individual units of data processing, the role of each process becomes very clear, and it is easy to build and maintain.

This is the same reason not only on the edge device, but also on the server side (cloud side), for persisting, analyzing, and visualizing the data that's collected by the edge device.

The biggest feature of Node-RED is that it connects the processing of Node.js in a sequential manner or in parallel with input/output data chunks in the form of messages. It can be said that this is very suitable for IoT data handling.

Again, as we discussed in the previous chapter, the standard architecture...
