  • Reducing Toil
    Define toil and how SRE practices help in minimizing repetitive work through automation.
  • Blameless Postmortems
    Introduce the importance of postmortems to review incidents objectively, understand root causes, and avoid blame.

Section 3: SRE Tools and Technologies

  • Monitoring and Observability Tools
    Cover tools such as Prometheus, Grafana, and New Relic that aid in monitoring and visualization.
  • Automation Tools
    Discuss automation tools like Kubernetes, Ansible, and Terraform that SREs use to reduce manual workload.
  • Incident Management and Alerting
    Explain the significance of alerting tools like PagerDuty and Opsgenie to manage incidents effectively.

Section 4: SRE Culture and Collaboration

  • SRE Culture
    Describe the culture of shared ownership, proactive communication, and continuous improvement within the SRE framework.
  • Collaboration between Dev and Ops
    Explain how SRE practices facilitate collaboration and smooth hand-offs between development and operations teams.
  • The Role of Soft Skills
    Emphasize communication, problem-solving, and teamwork as essential skills for SRE professionals.

Section 5: Incident Management and Troubleshooting

  • Incident Lifecycle
    Outline the incident lifecycle, from detection and response to resolution and review.
  • Root Cause Analysis
    Describe methods like the 5 Whys and Fishbone Analysis for effective troubleshooting.
  • On-Call Management
    Explain strategies for balancing on-call duties with work-life harmony.

Section 6: Performance and Scalability

  • Capacity Planning
    Explain how SREs work on forecasting resource needs to handle system demands.
  • Scaling Applications
    Discuss techniques for scaling applications, such as load balancing and autoscaling.
  • Resource Optimization
    Describe strategies for efficient resource usage to optimize costs and performance.

Section 7: Building an SRE Mindset and Career Path

  • Building an SRE Mindset
    Discuss the mindset shift required from reactive to proactive system management.
  • SRE Career Path
    Outline potential career paths in SRE, from junior roles to advanced roles like SRE Manager or Reliability Engineer.
  • Skills Development and Continuous Learning
    Highlight the need for ongoing education in areas like cloud computing, monitoring, and automation.
