Tell me about the configurations you've worked with, and the subsystems involved.

In my practice, I have worked with various system configurations, including server and network solutions. For example:

• Server configurations: setting up web servers (Nginx, Apache), databases (PostgreSQL, MySQL), including security, performance, and backup parameters.
• Network configurations: setting up VLANs, firewall rules, VPN tunnels to ensure secure access.
• Monitoring and logging subsystems: integrating log collection systems (ELK stack), status monitoring (Prometheus, Grafana).

In each case, I interacted with authentication subsystems, access management, backup and recovery, as well as deployment and update automation subsystems.
