As networks grow in size, we are seeing a shift from the traditional three-layer network architecture to a flatter, wider Spine-Leaf architecture. Most modern e-commerce, social media and cloud applications use distributed computing to serve their customers.  Distributed computing means that servers speak to servers and work in parallel to create dynamic web pages and answer customer question...
