Needless to say, integration with the underlying cloud provider provides a great productivity boost. However, a multi-cloud strategy is seen as essential to cope with various risks associated with data privacy, but also with contractual requirements, such as “data should stay within my jurisdiction”. Many cloud providers come with great observability stacks included, such as AWS’s CloudWatch, GCP’s StackDriver, and Azure’s Monitor. Observability is an essential feature of a platform, to ensure that “2am events” are converted into daily checks. What would I need more than vanilla Kubernetes? Furthermore, logs and metrics are collected. Great! Now you can run your application, you can direct traffic within the cluster and you can get traffic from end users into the cluster and to your application. For example, Google GKE sends logs, metrics and traces to Google StackDriver. Therefore, most managed Kubernetes offers also include a few more integrations with the underlying cloud provider. Knowing what is happening inside your Kubernetes cluster - also called “observability” - is essential to avoid unplanned downtime and customer disappointment.

Now Kubernetes needs to know how to bring traffic to your Pods and how to store their data, a function fulfilled by the so-called cloud controller. To this end, even the “most vanilla” Kubernetes comes with a Container Network Interface (CNI) addon, such as Calico. The above Kubernetes setup cannot really run anything yet: Kubernetes does not know how to make Pods, i.e., a collection of one-or-more containers, talk to each other.
