Every company that runs software in production eventually faces the same tension. The people who build software want to ship new features quickly. The people who keep software running want stability and predictability. These two goals seem to pull in opposite directions, and most organizations resolve the tension poorly.
**Author:** Betsy Beyer (Editor, with contributions from Google's SRE team)
**Estimated Reading Time:** 45 minutes
**What You'll Learn:** - Why 100% reliability is the wrong target for almost every service - How error budgets transform reliability from a technical goal into a business decision - What separates toil from real engineering work, and why eliminating it matters - How to design monitoring systems that alert humans only when they truly need to act - Why blameless postmortems are the foundation of organizational learning - How to think about distributed systems, load balancing, and cascading failures at scale
**Who This Book Is For:** This book is for software engineers who find themselves responsible for production systems. It is for operations professionals who want to apply engineering rigor to their work. It is for engineering leaders who need a framework for balancing reliability with feature velocity. And it is for anyone who has ever been paged at 3 a.m. and wondered if there is a better way.
Every company that runs software in production eventually faces the same tension. The people who build software want to ship new features quickly. The people who keep software running want stability and predictability. These two goals seem to pull in opposite directions, and most organizations resolve the tension poorly. The traditional solution is to create an operations team. Developers write code and hand it to operations, who deploy it, monitor it, and fix it when it breaks. This division creates a wall between building and running software. Developers optimize for shipping features. Operations optimizes for keeping systems stable. Each side develops its own incentives, its own culture, and its own vocabulary. The result is often a slow-motion conflict: developers complain that operations is too slow and bureaucratic, while operations complains that developers are reckless and don't care about reliability. Google faced this problem at a scale few companies can imagine. By the early 2000s, Google was running an enormous fleet of services across globally distributed datacenters. The traditional operations model was breaking down. There simply were not enough operations engineers to manage the complexity manually. The company needed a fundamentally different approach. The answer was Site Reliability Engineering, or SRE. The core insight was simple but radical: what if you asked software engineers to design and run the operations function? What if the people responsible for keeping systems reliable were the same kind of people who build systems in the first place? Instead of hiring operators to manage systems manually, Google hired software engineers and gave them a mandate to solve operational problems with code. This book is the definitive account of how Google's SRE teams work. It was written by the people who created…
