What operating systems have you worked with? What did you use for virtualization and deployment automation?

In my work, I used various operating systems, including Linux (Ubuntu, CentOS) and Windows Server. For virtualization, I used VMware and VirtualBox, as well as Docker for containerizing applications.

For deployment automation, I used tools:

• Ansible — for configuration management and deployment automation
• Jenkins — for CI/CD pipelines
• Terraform — for infrastructure as code management

For example, with Ansible, you can describe a playbook that automatically deploys an application on a server and configures the environment.
