Mastering DevOps and Site Reliability Engineering: Build Reliable, Scalable & Secure Systems
Mastering DevOps and Site Reliability Engineering provides a practical and structured introduction to the principles, technologies, and operational practices used to build and maintain reliable modern systems. It explores the relationship between DevOps, Site Reliability Engineering, and platform engineering while following the professional journey of engineers responsible for keeping complex infrastructure healthy.
The book moves beyond manual operational workflows and focuses on automation, reliability, scalability, security, observability, and continuous improvement. It begins with essential technical foundations such as Kubernetes, Infrastructure as Code, networking, and modern infrastructure practices, before progressing into the core disciplines of SRE.
DevOps, SRE & Modern Infrastructure
Understand how DevOps and SRE complement one another in modern engineering organizations. Explore the foundations required to design, automate, operate, and continuously improve cloud-native infrastructure and platforms.
Reliability, Observability & Scalability
Learn how observability, metrics, logging, and tracing provide insight into system health. Explore scalability and reliability practices designed to help engineering teams build systems capable of supporting changing workloads while maintaining dependable performance.
SRE Practices & Operational Resilience
Explore practical SRE concepts including Service Level Indicators (SLIs), Service Level Objectives (SLOs), error budgets, chaos engineering, blameless root-cause analysis, on-call management, business continuity, and disaster recovery.
Infrastructure Automation & GitOps
Learn how Infrastructure as Code and GitOps practices can reduce manual work, improve consistency, and support repeatable infrastructure management. The book connects automation with reliability and operational efficiency across modern cloud environments.
Security, Cost & Engineering Efficiency
Go beyond system availability by considering security, compliance, developer productivity, and cloud cost management. Explore budgeting, forecasting, and cost controls alongside practices for building secure and sustainable infrastructure.
