Kubernetes, Know as K8s, is an open source system used to manage Linux Containers across private, public and hybrid cloud environments.
In other words, Kubernetes can be used to manage microservice architectures and is deployable on most cloud providers.
Azure Kubernetes Service (AKS) packages and manages the complexity of putting together all of the preceding sources for you.

Instead, they focus solely on their worker nodes.
