📌 Important Notice & Guidelines

  • Scholarship Rule: The percentage of marks you score in the test will be equal to the percentage of scholarship you receive.
  • Weekly Test: Tests will be conducted every Friday.
  • Result Update: Your marks/results will be updated on the WhatsApp Channel every Saturday.
  • New Batches: New batches will start every Monday.

1. Introduction to DevOps

  • DevOps ek cultural aur technical approach hai jo development aur operations ko integrate karta hai.
  • Goal: Software delivery fast aur reliable banana.
  • Collaboration aur communication ko promote karta hai.
  • Benefits: Faster releases, fewer errors, aur better efficiency.

2. Software Development Life Cycle (SDLC)

  • SDLC software development ke process ko define karta hai: requirement, design, development, testing, deployment.
  • Models: Waterfall, Agile, aur DevOps approach.
  • Structured development aur predictable outcomes ensure karta hai.
  • DevOps me SDLC ko Continuous Delivery improve karta hai.

3. Version Control Systems (Git & GitHub)

  • Version control code changes track karne aur team collaboration me help karta hai.
  • Git commands: git init, git add, git commit.
  • Branching allow karta hai alag features pe kaam karne ke liye.
  • Remote repositories (GitHub) code share aur collaborate karne me help karte hain.

4. Continuous Integration (CI)

  • CI har code change ko automatically test aur integrate karta hai.
  • Automation tools: Jenkins, GitHub Actions, GitLab CI.
  • Early bug detection ensure karta hai.
  • Outcome: Stable aur production-ready code.

5. Continuous Delivery (CD)

  • CD release process automate karta hai taki applications kabhi bhi deploy ho sake.
  • Pipeline code ko testing se production tak automatically move karta hai.
  • Reliability: Consistent release process.
  • Advantage: Faster time-to-market.

6. Containerization (Docker)

  • Docker applications ko dependencies ke sath package karta hai.
  • Containers lightweight hote hain aur VMs se fast hote hain.
  • Dockerfile define karta hai image ka structure.
  • Portability aur efficiency improve hoti hai.

7. Container Orchestration (Kubernetes)

  • Kubernetes multiple containers ko manage karta hai across clusters.
  • Scaling: Automatically container resources adjust karta hai.
  • Load balancing: Traffic distribute karta hai containers ke beech.
  • Self-healing: Failed containers restart ho jate hain automatically.

8. Infrastructure as Code (IaC)

  • IaC infrastructure ko code ke through manage karta hai.
  • Tools: Terraform, Ansible, CloudFormation.
  • Automation: Servers configure karna faster aur consistent hota hai.
  • Advantage: Easy scaling aur reproducible environments.

9. Configuration Management

  • Systems ko consistently configure karna.
  • Tools: Ansible, Puppet, Chef, SaltStack.
  • Automation reduce karta hai manual errors.
  • Scalability: Thousands of servers easily manage ho jate hain.

10. Cloud Computing & DevOps

  • Cloud platforms scalable environment provide karte hain DevOps ke liye.
  • Platforms: AWS, Azure, Google Cloud.
  • Services: Compute, storage, databases, CI/CD tools.
  • Integration: Works seamlessly with DevOps tools.

11. Monitoring & Logging

  • Monitoring ensure karta hai applications aur servers healthy hain.
  • Logging events track karta hai for troubleshooting.
  • Tools: Prometheus, Grafana, ELK Stack.
  • Real-time alerts aur performance metrics provide karta hai.

12. Security in DevOps (DevSecOps)

  • Security integrate karna har stage me.
  • Shift-left approach: Early security checks.
  • Tools: SonarQube, Snyk, OWASP.
  • Automation: Security scans in CI/CD pipelines.

13. Case Studies & Mini Projects

  • Practical tasks DevOps concepts ko apply karne ke liye.
  • CI/CD Pipeline setup using Jenkins.
  • Docker + Kubernetes: Microservices deployment.
  • Infrastructure Automation with Terraform.
  • Monitoring dashboard with Grafana.

14. Automation & Scripting in DevOps

  • Automation reduces manual effort, ensures consistency, and speeds up the delivery process.
  • Scripting tools like Bash, Python, or PowerShell are used to automate repetitive tasks.
  • Automated testing, deployment, and infrastructure provisioning improve reliability.
  • Integration with CI/CD pipelines ensures end-to-end automation of software delivery.

15. Observability & Metrics in DevOps

  • Observability is the ability to understand system performance through logs, metrics, and traces.
  • Metrics like uptime, latency, and error rates help teams detect issues proactively.
  • Tools like Prometheus, Grafana, and ELK Stack provide visualization and alerting.
  • Good observability practices improve reliability and accelerate incident resolution.
