In this chapter, we looked at the underlying concepts inherent to software architecture. Even when the exposed principles have been in the industry for a while, they are still relevant, and it's worth considering them when working on architectural aspects. Something to remember is that high cohesion and low coupling refers to how you connect your components to shape your software architecture, and the SOLID principles apply to the design of each one of them.

To wrap this up, in this chapter, we have talked about how the software industry is evolving to embrace the new business challenges that companies are currently facing. In the next chapter, we will review what software architecture dimensions are in depth, and we will also learn how to use the C4 model to document software architectures.
