Can you describe the steps of the deployment pipeline? Starting from the code commit — what happens next?

After a code commit, a deployment pipeline is usually triggered, which includes the following steps:

1. Build — compiling the code, installing dependencies, preparing artifacts.
2. Test — running unit tests, integration tests, static code analysis.
3. Publish artifacts — uploading the built packages to the artifact repository.
4. Deploy to staging — deploying the application in an environment as close to production as possible.
5. Verification (Smoke tests, QA) — automated or manual checks of functionality.
6. Deploy to production — rolling out the update to the live server.
7. Monitoring & Rollback — tracking the application's status and the ability to revert in case of errors.

Each step can be automated using CI/CD systems (Jenkins, GitLab CI, GitHub Actions, etc.).
