Infrastructure, cost, and the cloud
You need to think about infrastructure as a set of components. How do you assemble those components and then interact with them? In addition to that, how do you keep everything evolving? Infrastructure is much more elastic—to use a cloud term—than static, as it was before. Applications that live on top of that used to have the monolithic stacks or classic three-tiered architecture, but nowadays with containers, VMs, and microservices-based architectures, that's changed rapidly. It's why everybody needs to understand from an engineering perspective how the application or a set of services behave. It's also why they keep tracking that and looking for anomalies, because that's how you make sure that the site or your service is more reliable.
