Writing your code for Pods and Containers

One of the keys to successfully using Kubernetes is to consider how you want your code to operate, and to structure it so that it fits cleanly into a structure of Pods and Containers. By structuring your software solutions to break problems down into components that operate with the constraints and guarantees that Kubernetes provides, you can easily take advantage of parallelism and container orchestration to use many machines as seamlessly as you would use a single machine.

The guarantees and abstractions that Kubernetes provides are reflective of years of experience that Google (and others) have had in running their software and services at a massive scale, reliably, and redundantly, leveraging the pattern of horizontal scaling to tackle massive problems.
