- Code commit
- Build
- Test
- Review
- Merge
- Artifact release
- Deployment
This approach, known as agile software development, not only improves development speed and quality but also significantly influences the time-to-market for software products.
Infrastructure as Code (IaC)
Another fundamental principle of DevOps is Infrastructure as Code (IaC). As the name suggests, IaC involves managing and provisioning infrastructure through code, which brings about a higher level of automation and consistency across environments.
IaC enhances consistency and reproducibility by:
- Automating resource provisioning and management
- Promoting transparency and accountability via version-controlled code
- Facilitating easier rollbacks in the event of issues or bugs
Moreover, IaC plays a crucial role in facilitating testing and deployment, enabling the testing of code for errors and oversights before deployment.
Monitoring and Feedback
The third pillar of DevOps is monitoring and feedback. Continuous monitoring provides real-time visibility into the application and infrastructure performance, enabling swift issue resolution, and fostering operational efficiency.
Conversely, feedback provides continuous insights into application performance and usage patterns, which facilitates iterative development and ensures the achievement of project objectives. The presence of feedback loops is essential in enhancing software quality and aligning development, testing, and deployment processes with project goals.
