Help creating software architecture diagram

Question

I was wondering if anyone had any tips on how I create recreate the diagram above, any tips would be helpful.

Please and thank you. Are there any packages for nested rectangles, and rendering cubes?

Answer 1

Apart from the fit library, which has been mentioned by Dr. Manuel Kuehner, there are a few more libraries that are convenient here: positioning, shapes.geometric and shapes.symbols. The missing shapes can be found here and here. The rest is just patching things together (and creating a "new" pic). Everything is enjoyable except for punching in these texts.
