Chapter 6: Clustering with Kubernetes

1. A server cluster is a set of connected computers that work together in such a way that they can be used similarly within a single system.
2. Kubernetes Node is just a worker, that is, a host that runs containers. Kubernetes Control Plane Master is responsible for everything else (providing the Kubernetes API, Pod orchestration, and more).
3. Microsoft Azure, Google Cloud Platform, and Amazon Web Services.
4. Deployment is a Kubernetes resource that's responsible for Pod orchestration (creating, terminating, and more). Service is an (internal) load balancer that provides a way to expose Pods.
5. kubectl scale.
6. Docker Swarm and Mesos.
