1. VMware

VMware powers virtualization across hosts, carving physical servers into efficient pools of compute, storage, and networking. It streamlines operations and anchors private and hybrid cloud designs across the data center.

Why It's Important

Virtualization squeezes more value from hardware, speeds provisioning, and hardens continuity with clustering and recovery features—key levers for cost control and availability.

How to Improve VMware Skills

1. Right-size and place VMs: Align vCPU and memory with real workload needs. Respect NUMA boundaries. Keep reservations and limits intentional, not accidental.
2. Keep the stack current: Standardize hosts with vSphere Lifecycle Manager. Patch ESXi, vCenter, and tools on a cadence for stability and security.
3. Lean on cluster brains: Enable DRS and HA. Tune DRS aggressiveness and VM-VM/VM-Host rules to reduce noisy neighbor effects and preserve app affinity.
4. Tune storage: Use Storage DRS and Storage I/O Control. Monitor latency per datastore and adopt adaptive queue depths. Prefer VMFS/NFS backed by fast media.
5. Shape network traffic: Standardize on vSphere Distributed Switch. Use Network I/O Control to prioritize storage, vMotion, and latency-sensitive flows.
6. Modernize VM compatibility: Update VM hardware versions and VMware Tools to unlock features and performance improvements.
7. Observe and act: Track contention (CPU ready, co-stop, ballooning, swap) and automate responses with policies or remediation runbooks.

Collect, analyze, iterate. The feedback loop is where performance gains stick.
