As AI and ML rapidly power modern digital services from recommendation engines to generative models, moving these workloads into production exposes critical gaps in traditional operations. Site reliability engineering (SRE) applies software engineering principles to infrastructure, making SRE uniquely positioned to own the reliability, observability, and resilience of complex AI-driven environments. This book bridges the gap between traditional SRE practices and the innovative strategies required to manage AI-driven infrastructures such as LLM models effectively, offering readers a focused guide for this transformative era. Each chapter walks the reader through core concepts such as versioning of models and data, pipeline monitoring, and security testing for AI APIs, while providing concrete SRE patterns for uptime, rollback, and incident management in AI-driven environments. You will learn how to design service-level objectives that reflect AI-specific quality metrics, implement robust monitoring and alerting for model drift and data quality, secure AI-backed APIs against prompt injection and other attacks, and coordinate releases across code, data, and models in a complex environment.
