Foundations of Site Reliability Engineering

In today's digital landscape, keeping software systems running reliably is a critical requirement for any organization. This text-based course introduces you to the core principles of Site Reliability Engineering, bridging the gap between software development and systems operations. You will gain a solid understanding of how to design, maintain, and scale resilient applications. Through clear written explanations, practical examples, and conceptual exercises, you will transition from a traditional operations mindset to a modern reliability engineering perspective. What you'll learn: - Understand the fundamental principles of SRE, including service level indicators (SLIs), objectives (SLOs), and error budgets. - Apply modern observability practices using structured logging, metrics collection, and distributed tracing. - Manage system capacity and scale infrastructure reliably using automation and infrastructure-as-code concepts. - Coordinate incident response workflows, conduct post-mortems, and establish blameless post-incident cultures. - Configure basic CI/CD pipelines to ensure safe, automated, and progressive code deployments. - Practice designing resilient software architectures that gracefully handle failures and minimize downtime. The course begins with foundational definitions and key SRE terminology before guiding you through practical strategies for monitoring, incident management, and automation. You will progress from theoretical concepts to applying reliability practices in real-world scenarios. This course is designed for beginner software engineers, systems administrators, and IT professionals who want to understand modern reliability engineering. No prior SRE experience is required.
