What is the point of Kubernetes?

The purpose of Kubernetes is to make it easier to organize and schedule your application across a fleet of machines. At a high level it is an operating system for your cluster. Basically, it allows you to not worry about what specific machine in your datacenter each application runs on.

What is Kubernetes good for?

Kubernetes allows you to deploy cloud-native applications anywhere and manage them exactly as you like everywhere. … With containers, it’s easy to quickly ramp application instances to match spikes in demand. And because containers draw on resources of the host OS, they are much lighter weight than virtual machines.
