Scalability and Functional Decomposition

I got interested in this style of architecture, as in breaking up what would otherwise be a large monolith into multiple services back in 2010. I'd read this book, The Art of Scalability, and in the book, they had this scale cube, which was a three-dimensional model of scaling. And that really resonated with me, because up until then, I'd just been building a series of monolithic applications.
