• Perform system patching, upgrades, certificate maintenance, and lifecycle-management activities for ESXi hosts, vCenter, and related VMware components.
• Monitor and optimize virtual infrastructure performance, capacity, resource utilization, availability, and stability.
• Troubleshoot complex issues involving virtual machines, hypervisors, virtual networking, storage connectivity, physical servers, and supporting infrastructure.
• Plan and support workload migrations, technology refreshes, and transitions between test, lab, and operational environments.
• Apply platform-independent virtualization concepts to support the evaluation or adoption of alternate hypervisors, private-cloud platforms, or container-based solutions.
