DevOps is a set of practices that combines software development (Dev) and IT operations (Ops). It aims to shorten the development lifecycle and deliver high-quality software continuously.
- Continuous Integration (CI): Automate code integration from multiple contributors.
- Continuous Delivery (CD): Automate deployment of code to production.
- Infrastructure as Code (IaC): Manage infrastructure using code and automation tools.
- Monitoring & Logging: Track application performance and system health.
- Collaboration: Foster communication between development and operations teams.
- Version Control: Git, GitHub, GitLab
- CI/CD: Jenkins, GitHub Actions, GitLab CI
- Containerization: Docker, Kubernetes
- Configuration Management: Ansible, Chef, Puppet
- Monitoring: Prometheus, Grafana, ELK Stack
- Developer pushes code to repository.
- CI server runs automated tests.
- If tests pass, code is built and deployed to staging.
- Automated deployment to production after approval.
- Monitoring tools track performance and errors.
- Automate repetitive tasks.
- Use version control for all code and configurations.
- Monitor systems proactively.
- Foster a culture of collaboration and feedback.
- Continuously improve processes.
