Containerization & Virtualization : Knowledge of Podman, Kubernetes, Helm, and / or OpenStack; experience with KVM / QEMU is advantageous.

Storage Systems : Experience with Ceph and Rook is highly valued.

Database Expertise : Understanding of relational databases (MySQL, MariaDB) and experience with etcd.

Monitoring and Logging : Familiarity with tools like ELK (Elasticsearch, Logstash, Kibana), Prometheus, and Grafana.
