I have recently started working on a migration process to move our company deployments over to Kubernetes (from Fleet, if you were interested, which was, at the time of deployment, a pretty cutting-edge technology, but it is pretty low level, and you have to provide stuff like load balancing and DNS yourself).
A colleague of mine had already done the hard work in actually spinning up a Kubernetes cluster on AWS (using EKS) and generally most of the boilerplate around service deployment, so having had a general intro and deploying my first service (single microservice deployed as a Kubernetes “service” running inside a “pod”), which mostly just involved copy and pasting from my colleagues examples, my next goal was to deploy our monitoring setup. We currently use Prometheus and Grafana, and those still seem to be best in class monitoring systems, especially with Kubernetes.
