Introduction: Your Journey to Becoming an SRE
Site Reliability Engineering (SRE) is a discipline that combines software engineering with operations expertise to build and maintain highly reliable, scalable systems. As a junior SRE, you’ll be responsible for ensuring service reliability, automating operational tasks, and bridging the gap between development and operations teams.
This comprehensive learning path will take you from foundational programming skills through the core technologies that power modern infrastructure. Each step builds upon the previous one, preparing you for real-world SRE challenges including:
- Automation: Writing scripts and tools to eliminate toil
- Infrastructure as Code: Managing cloud resources programmatically
- Container Orchestration: Deploying and scaling applications reliably
- Observability: Monitoring, alerting, and debugging production systems
- Incident Response: Responding to and learning from service disruptions
Whether you’re transitioning from development, operations, or starting fresh in tech, this roadmap provides the essential knowledge and resources you need.
