DevOps is a combination of "Development" (software creation) and "Operations" (IT infrastructure and deployment). It is a collaborative approach that aims to automate, speed up, and improve the software development and delivery process.
DevOps is not just a set of tools — it's a culture, mindset, and workflow that encourages communication and collaboration between developers and IT operations teams.
🔄 Main Goal of DevOps
-
Deliver software updates quickly, reliably, and frequently
-
Improve team collaboration and transparency
-
Reduce bugs, downtime, and manual work
-
Increase efficiency, security, and system stability
🧱 Core Components of DevOps
| Component | Description |
|---|---|
| 🧑💻 Version Control | Manage code changes (e.g., Git, GitHub) |
| 🔍 Automated Testing | Check code quality before deployment |
| 🚀 CI/CD (Continuous Integration/Continuous Delivery) | Automate build, test, and deployment processes |
| ⚙️ Infrastructure as Code (IaC) | Manage servers and configurations using code |
| 📊 Monitoring & Logging | Track system performance and errors in real time |
🔧 DevOps Lifecycle Stages
-
Plan – define project goals and tasks
-
Develop – write and update code
-
Test – automatically test code for bugs
-
Integrate – merge code into the main branch
-
Deploy – release software to users
-
Monitor – observe system health and performance
🚀 Popular DevOps Tools
| Purpose | Tools |
|---|---|
| Version Control | Git, GitHub, GitLab |
| CI/CD | Jenkins, GitLab CI, GitHub Actions, CircleCI |
| Containerization | Docker, Kubernetes |
| Monitoring | Prometheus, Grafana, New Relic |
| Configuration Management | Ansible, Terraform, Puppet |
