DevOps Practices
- Continuous Integration (CI):
- Developers frequently integrate code into a shared repository.
- Automated builds and tests are run to identify issues early.
- Continuous Delivery (CD):
- Ensures that code changes are automatically prepared for release.
- Automates the release process so that the software can be deployed at any time.
- Continuous Deployment:
- Extends continuous delivery by automatically deploying every change that passes all stages of the production pipeline.
- No human intervention is needed for deployment.
- Infrastructure as Code (IaC):
- Infrastructure is provisioned and managed using code.
- Tools like Terraform, Ansible, Puppet, and Chef are used.
- Automated Testing:
- Automated tests are integrated into the CI/CD pipeline to catch defects early.
- Types include unit tests, integration tests, and end-to-end tests.
- Monitoring and Logging:
- Continuously monitor applications and infrastructure to detect issues.
- Tools like Prometheus, Grafana, ELK Stack, and Splunk are used.
- Microservices Architecture:
- Break down applications into small, independent services.
- Each service can be developed, deployed, and scaled independently.
- Version Control:
- Use systems like Git to manage and track code changes.
- Ensures collaboration and version management.
- Collaboration and Communication:
- Encourage shared responsibility and open communication between development and operations teams.
- Use tools like Slack and Microsoft Teams for ChatOps.
- Security as Code:
- Integrate security practices into the DevOps process.
- Automate security testing and compliance checks.
