Who handles deployment — developers or DevOps?

The responsibility for deployment can vary depending on the organization and team. In some companies, developers deploy their own changes, especially in small teams or when using CI/CD, where the process is automated.

In other cases, the deployment is handled by the DevOps team or individual operations engineers who monitor the stability and security of releases.

Joint work is often practiced: developers prepare and test the code, while DevOps engineers manage the infrastructure and deployment process. In modern agile teams, there is a move towards a DevOps culture, where developers and operations specialists work together and can perform deployments collaboratively.
