1. Introduction to DevOps: How Development and Operations Work Together
DevOps is a modern approach to software development that brings development and operations teams closer together. Instead of treating software development, testing, deployment and infrastructure management as completely separate activities, DevOps encourages collaboration, automation and continuous improvement throughout the software delivery lifecycle.
Key areas
- What DevOps Means
- Development vs. Operations
- DevOps Culture and Collaboration
- Benefits of DevOps
- DevOps Lifecycle
- DevOps in Modern Software Development
2. CI/CD Explained: Automating Software Development and Deployment
Continuous Integration and Continuous Delivery or Deployment are fundamental DevOps practices that help development teams deliver software faster and more reliably. CI/CD pipelines automate important stages such as code integration, building, testing and deployment, reducing manual work and allowing teams to release software more frequently.
Key areas
- Continuous Integration
- Continuous Delivery
- Continuous Deployment
- Automated Testing
- Build Pipelines
- Deployment Automation
- Popular CI/CD Tools
3. DevOps Automation: How Automation Improves Software Delivery
Automation is one of the most important principles of DevOps. By automating repetitive development, testing, deployment and infrastructure tasks, organisations can reduce human errors, improve consistency and accelerate software delivery.
Key areas
- Automated Builds
- Automated Testing
- Automated Deployments
- Infrastructure Automation
- Configuration Management
- Reducing Manual Errors
4. Git and DevOps: Why Version Control Is Essential for Modern Development
Git is a distributed version control system that allows developers to track code changes, collaborate with other developers and maintain different versions of a software project. Git is particularly important in DevOps because modern CI/CD pipelines rely heavily on version-controlled source code.
Key areas
- Git Fundamentals
- Branching Strategies
- Pull Requests
- Code Reviews
- Merge Conflicts
- Git Workflows
- Git in CI/CD Pipelines
5. Docker and DevOps: Understanding Containerization
Docker provides a way to package applications together with their dependencies into lightweight, portable containers. Containerization helps development and operations teams create more consistent environments across development, testing and production.
Key areas
- What Containers Are
- Docker Fundamentals
- Containers vs. Virtual Machines
- Docker Images
- Docker Compose
- Container-Based Deployments
- Benefits of Containerization
6. Kubernetes and DevOps: Managing Applications at Scale
Kubernetes is an open-source container orchestration platform designed to help organisations deploy, manage and scale containerized applications. It provides capabilities such as automated scheduling, scaling, service discovery and self-healing, making it an important technology for modern cloud-native applications.
Key areas
- What Kubernetes Is
- Containers and Orchestration
- Pods and Deployments
- Services
- Scaling Applications
- Self-Healing Infrastructure
- Kubernetes in Production
7. Infrastructure as Code (IaC): Managing Infrastructure with Code
Infrastructure as Code is the practice of managing and provisioning computing infrastructure through machine-readable configuration files rather than relying primarily on manual processes. IaC allows infrastructure configurations to be version controlled, automated and reproduced consistently across different environments.
Key areas
- What Infrastructure as Code Means
- Infrastructure Automation
- Terraform
- Cloud Infrastructure
- Version-Controlled Infrastructure
- Reproducible Environments
- Benefits of IaC
