What is the main role of a DevOps engineer in the process of system development and operation?

The main role of a DevOps engineer is to ensure effective collaboration between software development and operations. This is achieved through automation of build, testing, deployment, and monitoring processes.

The DevOps engineer is responsible for:

• Setting up CI/CD (continuous integration and delivery) for rapid and secure release of new versions.
• Automating infrastructure using scripts and tools (e.g., Terraform, Ansible).
• Monitoring and logging systems for quick detection and resolution of issues.
• Ensuring stability and scalability of applications.

Thus, the DevOps engineer helps reduce time to market and improve software quality.
