While writing about load balancers, I stumbled upon the CAP theorem, a distributed systems concept, and was the perfect segue into my next article.

Load balancers serve to distribute load among multiple servers to prevent single servers from overloading. In other words, it increases the availability of applications for users. Backtracking from load balancers, the CAP theorem states that any system can only support two among the three: Consistency, Availability, and Partition. Distributed systems engineering is full of tradeoffs and CAP theorem focuses on one such tradeoff between Consistency and Availability.
