C4 Model Diagram

"The C4 model was designed to help describe, document, and diagram custom-built, bespoke software systems. From this perspective, the C4 model can be used to describe a variety of software architectures (monolithic or distributed), built in a variety of programming languages, deployed on a variety of platforms (on-premises or cloud)" - C4Model.com.
