Key Concepts in DevOps

Traditional Models of Solution Delivery

1. Waterfall Model

   • Process: Requirements analysis -> Project planning -> Development -> Testing -> Maintenance.
   • Challenges: Difficulty in accommodating new requirements, high cost and time-consuming to make changes.

2. Agile Model

   • Process: Shorter cycles, continuous feedback (Sprints, usually 2 weeks).
   • Advantages: Faster delivery, client requirements better understood.
   • Disadvantages: Product not fully tested in production, developers and ops work in silos.

Introduction to DevOps

• DevOps: Integration of development and operations teams to improve efficiency.
• Phases: Planning, coding, building, testing, deploying, operating, monitoring.
• Tools: Git, Jenkins, Selenium, Maven, Chef, Ansible, etc.

Detailed Breakdown of DevOps Tools

Key Tools

• Git: Version control software.
• Jenkins: Integration and CI/CD automation tool.
• Docker and Kubernetes: Containerization and orchestration.
• Terraform: Infrastructure as Code (IaC) tool.
• Selenium: Automated testing.
• Chef: Infrastructure automation tool.

Cloud Computing and Containerization

• Popular Cloud Providers: AWS, Azure, Google Cloud.
• Containerization Tools: Docker, Kubernetes.
• CI/CD Tools: Jenkins, GitLab CI.
• Monitoring Tools: Prometheus, Grafana.

Advanced DevOps Skills for 2024
