This curriculum spans the full operational lifecycle of server virtualization, equivalent in scope to a multi-workshop technical engagement for designing, securing, and maintaining enterprise virtual infrastructures.

Module 1: Virtualization Architecture and Hypervisor Selection

  • Evaluate type-1 versus type-2 hypervisors based on performance overhead and security isolation requirements for production workloads.
  • Compare VMware ESXi, Microsoft Hyper-V, and KVM based on existing infrastructure dependencies and vendor support agreements.
  • Assess hardware compatibility list (HCL) adherence when selecting hypervisors to avoid driver and firmware conflicts.
  • Determine CPU virtualization extensions (Intel VT-x, AMD-V) enablement requirements in BIOS/UEFI across server fleets.
  • Plan for hypervisor licensing models that align with core-based, socket-based, or subscription-based cost structures.
  • Design host-level partitioning strategies to balance VM density against resource contention risks.

Module 2: Resource Allocation and Performance Optimization

  • Allocate CPU reservations and limits to prioritize critical applications during peak load periods.
  • Configure memory overcommitment policies while monitoring ballooning and swapping to prevent performance degradation.
  • Implement NUMA node alignment for large VMs to reduce cross-socket memory access latency.
  • Set storage I/O throttling policies to prevent noisy neighbor effects in shared datastore environments.
  • Monitor and adjust virtual CPU-to-core ratios based on actual workload utilization trends.
  • Use performance baselines to identify and remediate VM sprawl and underutilized instances.

Module 3: Storage Design and Virtual Machine Provisioning

  • Select between thick-provisioned and thin-provisioned virtual disks based on storage capacity planning and performance SLAs.
  • Configure VMFS, NFS, or vSAN datastores with appropriate block sizes and RAID levels for I/O patterns.
  • Implement storage DRS to automate load balancing and initial placement of VMs across datastores.
  • Design snapshot retention policies that account for performance impact and backup integration requirements.
  • Integrate storage multipathing to ensure redundancy and failover for critical VMs.
  • Plan clone and template workflows to standardize VM deployment while minimizing storage duplication.

Module 4: Network Virtualization and Connectivity Management

  • Design vSwitch and distributed switch topologies to segment traffic by security zone and performance class.
  • Configure VLAN tagging at the port group level to maintain network policy consistency across VMs.
  • Implement NIC teaming with appropriate load balancing and failover policies for physical uplinks.
  • Allocate network resource pools to guarantee bandwidth for high-priority VMs during congestion.
  • Integrate virtual firewalls and micro-segmentation policies with NSX or equivalent platforms.
  • Validate MTU settings across physical and virtual network layers to support jumbo frames where required.

Module 5: High Availability, Fault Tolerance, and Clustering

  • Configure vSphere HA admission control policies to ensure sufficient failover capacity in the cluster.
  • Enable VM-level fault tolerance only for stateful applications requiring zero downtime.
  • Design DRS automation levels to balance workload distribution without excessive VM migrations.
  • Implement host profiles to standardize configuration across cluster nodes and reduce drift.
  • Test cluster failover scenarios to validate VM restart priorities and datastore heartbeat resilience.
  • Monitor host isolation response settings to prevent split-brain conditions during network outages.

Module 6: Backup, Recovery, and Disaster Preparedness

  • Integrate image-level backup tools with changed block tracking to minimize backup windows.
  • Validate application-consistent snapshots using VSS or equivalent frameworks for databases.
  • Test VM restore procedures including full recovery, file-level restore, and cross-site failover.
  • Configure backup proxy placement to avoid network bottlenecks during data transfer.
  • Define RPO and RTO targets for VMs and align backup frequency and replication accordingly.
  • Document and audit backup retention schedules to meet compliance and legal hold requirements.

Module 7: Security Hardening and Compliance Enforcement

  • Apply hypervisor security baselines from CIS or DISA STIGs to harden ESXi or Hyper-V hosts.
  • Restrict administrative access to vCenter using role-based access control (RBAC) and SSO integration.
  • Encrypt VMs at rest using vTPM and VM encryption features for sensitive workloads.
  • Audit VM creation and configuration changes through logging and SIEM integration.
  • Isolate management traffic on dedicated VLANs and physical NICs to reduce attack surface.
  • Enforce secure VM templates with updated OS patches, disabled default accounts, and logging enabled.

Module 8: Monitoring, Capacity Planning, and Lifecycle Management

  • Deploy monitoring agents or agentless tools to track VM and host-level performance metrics.
  • Generate capacity forecasts using historical growth trends for CPU, memory, and storage.
  • Identify candidates for VM retirement or rightsizing based on utilization thresholds.
  • Standardize VM naming, tagging, and ownership metadata to improve accountability.
  • Integrate virtualization events with ITSM tools for incident and change management workflows.
  • Plan hypervisor patching cycles using maintenance mode and rolling upgrades to minimize downtime.
