CI/CD - Continuous Integration and Continuous Delivery/Deployment

01

Code Commit

Developers commit code changes to a shared repository, ensuring frequent updates and avoiding large, complex merges, promoting collaboration and code quality.

02

Automated Testing

Committed code triggers automated tests that verify functionality, security, and performance, identifying issues early and ensuring high code quality and stability.

03

Build Process

Successful tests lead to an automated build process, compiling the code into executable applications or binaries, ensuring consistent and reproducible builds across environments.

04

Continuous Integration

Integrated code undergoes further testing, including integration tests, to verify that new changes work seamlessly with existing code and do not introduce new issues.

05

Deployment to Staging

After passing integration tests, the application is deployed to a staging environment that mirrors production, allowing for final testing and validation by stakeholders.

06

Continuous Deployment/Delivery

Once validated in staging, the application is automatically deployed to production (deployment) or prepared for manual release (delivery), ensuring rapid, reliable, and frequent updates.
