Implement security and governance: SCC/PSA, image/OVA pipelines, certificate/PKI, secrets management, network isolation policies, compliance operator/OpenSCAP. Establish observability for VMs and platform: Prometheus/Alertmanager, Grafana, EFK/Loki, SLOs/error budgets, capacity planning, chargeback/showback. Automate lifecycle and operations: cluster/node tuning, performance profiles, day-2 upgrades of CNV/Operators, Ansible/Terraform pipelines, GitOps patterns. Partner with app/infra/security teams to define standards, landing zones, golden images, and self-service workflows; mentor engineers and review designs.
