Kubernetes
Kubernetes is a platform to schedule and run containers on cluster of virtual machines.
It runs on bare metal, VMs,, private datacenter and public cloud.
As nodes are added or removed from the cluster, a DaemonSet will add or remove the required pods.
Jobs -- Supervisor process for pods carrying out batch jobs.
Services -- allow communication between one set of deployments with another.
Use a service to get pods in two deployments to talk to each other.
