“In modern software development organizations, however, what gets used in development and testing environments has a habit of showing up in production. This was the opportunity that Kubernetes was built to take advantage of. It provided developers with a means – an open source means, naturally – of taking the containers they were so enamored of and running them in production environments, but without having to make determinations such as which containers run on which hardware. In its initial incarnation, this was the simple, basic job that Kubernetes was hired for.”
