Book Description

In today’s digital landscape, ensuring service reliability is more than just a necessity—it’s a competitive advantage. SLIs and SLOs Demystified equips software engineers, SREs, and business leaders with the knowledge to build, measure, and manage service level indicators (SLIs) and service level objectives (SLOs) efficiently. Written by Alexandra F. McCoy—an experienced site reliability engineer with over a decade of experience in the cloud and technology industry—this book simplifies complex reliability concepts for engineers at all levels.

Starting with a review of reliability engineering basics, Alexandra provides a step-by-step approach to defining impactful SLIs, facilitating productive SLO discussions, and integrating observability into your monitoring strategy. You’ll also see how these principles apply to web applications, distributed systems, databases, and new features through real-world examples that can help you develop SLIs and SLOs for your specific environment. The book goes beyond implementation to explore the financial impact of reliability, alerting strategies, integration with incident management, and using error budgets for business decisions.

By the end of this book, you’ll be able to drive operational excellence, minimize unplanned downtime, and optimize end user experiences with well-established reliability metrics.

Review

“This book is a timely and invaluable resource for software engineers, administrators, and organizations seeking to optimize their systems and architecture. It masterfully breaks down complex reliability engineering principles into actionable insights, emphasizing the importance of prioritizing reliability at the organizational level. What sets this book apart is its hands-on approach, offering detailed examples and practical guidance on crafting SLIs and SLOs for diverse scenarios. These examples empower readers to implement reliability engineering principles effectively.

The book also explores observability, monitoring, alerting, and incident management, highlighting the financial impact of SLIs and SLOs on infrastructure. By demystifying these critical concepts, the author provides a clear roadmap for improving system reliability and performance […].”

Sayali Kulkarni, Customer Reliability Engineer at Sysdig

“SLIs and SLOs Demystified is a must-read book for those facing challenges in linking the technical and business worlds for service metrics, level indicators, and objectives. Alexandra dissects and examines each aspect of SLIs and SLOs holistically, explaining why they work magnificently to bring light to the system’s internal states and trends and how businesses can take advantage of adopting them. SREs can learn how to define SLIs purposefully to support business growth while negotiating SLOs with leaders for the company’s best interest.”
