Distributed systems come in many shapes and sizes, and they are increasingly a major part of how we build and deliver software. But distributed systems also create challenges. At face value, they appear to offer the ability to create more stable software. No longer should the death of a single machine take our system offline, right? Unfortunately, the world is not that simple. While distributed systems seem simple on the surface, complexity emerges from a set of initially straightforward interactions between computers. Calls can take too long or fail, networking equipment can catch fire, configuration errors can send your network packets down the wrong trouser leg of the internet, data centers can be taken out by regional conflict, you could be hit by an indiscriminate distributed denial of service attack, or a simple cache failure could bring your whole system down. It gets worse. A distributed system also consists of the people who operate and use the system, and they can be their own sources of instability. However, the human component is also the most vital one in taking our distributed systems and making them resilient. In this book, I explore the nature of distributed systems and the notion of resiliency in general. Through the following 16 chapters, I’ll take you on a journey in which we look at everything from the humble timeout to building collapse; retrying calls to CAP theorem; rate limiting to sociotechnical systems. By the end, you’ll know a lot more about how to make your system more resilient from both a technical and a people point of view, and you’ll have a much more rounded understanding of the notion of resilience in general.
