In cloud-based architectures, the situation is different and the network has become even more important. Let’s imagine a typical cloud-based architecture situation. You run a datacenter with a flexible number of allocated computing instances (for example, due to the pricing model and volatile demands for CPU). Your datacenter serves distributed applications that are backed by, for example, microservices. Additionally, let’s say that your applications are distributed via Docker containers to give your DevOps teams some flexibility. In situations like this you need more networking than ever. Your network must shoulder all the communications required between the microservices. It serves as a virtual nervous system for your applications.
