Great technologies come in many guises. Some start small. They can be created by just one person, quietly working alone to solve a spe‐ cific problem in a personal way. Ruby on Rails and Node.js are two examples that exceeded their creator’s wildest dreams. Other tech‐ nologies make an immediate impact. The rarest of these win wide‐ spread support in just a few years—in a blink of an eye in our industry. Kubernetes and containers are such a technology. They represent a fundamental shift in the industry platform—as critical as HTTP and Linux.
