Today I want to tell you a few words about how you can describe your system through mathematical equations — at least to some degree. You will get familiar with terms like Contention, Coherency, and Coherency Delay. Additionally, I want to show you laws and their mathematical equations that can help you calculate the impact of these 3 mechanics on your application.
This article is more focused on overall system design and architecture than any other written by me till today — so consider yourself warned. In the article, I will try to answer a question: Can we scale systems indefinitely?
