Mastering DevOps Foundations: CI/CD, GitOps and Monitoring

This comprehensive foundation course offers an integrated understanding of DevOps principles and Site Reliability Engineering (SRE) practices, focusing on continuous integration and delivery (CI/CD), GitOps, and observability in modern IT environments.

Participants will explore how DevOps and SRE frameworks work together to improve software reliability, speed, and quality through automation, collaboration, and data-driven operations. The course blends theory with practical applications — covering pipelines, infrastructure as code, incident response, monitoring, and feedback loops — to help professionals streamline workflows and deliver resilient digital services at scale.

By the end of the programme, participants will be equipped with the skills to design and manage high-performing systems that align engineering excellence with organisational goals.

Section 1: Foundations of DevOps and SRE

• Understanding DevOps culture and philosophy.
• The evolution from traditional IT operations to continuous delivery.
• Core SRE principles: reliability, availability, and service-level objectives (SLOs).
• Bridging development and operations through shared accountability.
• The CALMS framework (Culture, Automation, Lean, Measurement, Sharing).

Section 2: Continuous Integration and Continuous Delivery (CI/CD)

• The CI/CD pipeline architecture and workflow.
• Automating builds, testing, and deployments.
• Integrating tools: Jenkins, GitLab CI, GitHub Actions, and Argo CD.
• Managing environments and rollbacks with version control.
• Best practices for secure and scalable release management.

Section 3: GitOps and Infrastructure as Code (IaC)

• Introduction to GitOps principles and benefits.
• Using Git as a single source of truth for infrastructure management.
• Popular GitOps tools and workflows: Argo CD, Flux, and Terraform.
• Automating environment provisioning and configuration.
• Policy enforcement, change tracking, and rollback strategies.

Section 4: Observability, Monitoring, and Reliability

• Defining observability vs. monitoring.
• Key metrics: SLIs, SLOs, and error budgets.
• Designing telemetry systems with logs, metrics, and traces.
• Tools overview: Prometheus, Grafana, ELK Stack, and OpenTelemetry.
• Incident response, alerting, and postmortem best practices.

Section 5: Building a DevOps & SRE Culture

• Continuous feedback and improvement loops.
• Collaboration between developers, ops, and business teams.
• Automation and measurement for scaling reliability.
• Managing change and reducing toil through SRE practices.
• Developing maturity models for DevOps and SRE adoption.
