Why hiding it, I like this diagram. A lot. It represents a typical “cloud side” (Azure) system using some component called “XYZ”, that happens to be written in C or C++. Most likely C, because it has to be integrated with NODE.JS.
Here is why. It seems Microsoft marketing has overwhelmed the target audience with dozens of made to be equally important Azure “services” (for the lack of better word). The “full Monty”: Posters, charts and animations. It is enough for Azure newcomer (developer or decision maker) to make and keep her dizzy, instead of producing focused and relaxed visitor, when entering the Azure yonder.
