Have you ever wondered why you are deploying your multi-platform applications using containers? Is it just a matter of “following the hype”? In this article, I’m going to ask some provocative questions to make my case for Why Kubernetes is the new application server.
You might have noticed that the majority of languages are interpreted and use “runtimes” to execute your source code. In theory, most Node.js, Python, and Ruby code can be easily moved from one platform (Windows, Mac, Linux) to another platform.
