Description
The code is a LaTeX document that defines a stock software architecture using TikZ package to create a graphical representation of the architecture. The architecture is composed of three cloud services: Cloud Run, Google Cloud C#, and App Engine, each represented by a rectangular box with rounded corners and a different color.
Inside each cloud service box, there are several colored boxes that represent different functionalities or features of that cloud service. The colors of the inner boxes vary depending on the cloud service they belong to. The boxes are arranged in a hierarchical manner, with the section headers on top and the specific features or functionalities at the bottom.
The code defines various styles for the elements in the architecture, such as sectionHeader, sectionContainer, and coloredBox. It also defines the colors used in the architecture, such as cloudrunMain, cloudrunSecond, appengineMain, appengineSecond, and reportsMain.
The code uses various TikZ commands to position the elements in the architecture relative to each other, such as above, below, left, and right. It also uses the calc library to perform mathematical operations on coordinates. Finally, the code uses the backgrounds library to add a background color to the architecture.
