This curriculum spans the equivalent of a multi-workshop operational immersion, addressing the same virtualization design, deployment, and governance challenges encountered in enterprise infrastructure transformations and internal platform teams.
Module 1: Virtualization Architecture and Infrastructure Planning
- Selecting between Type 1 and Type 2 hypervisors based on performance requirements, security posture, and hardware compatibility in production environments.
- Determining CPU and memory overcommitment ratios while balancing resource efficiency against risk of VM performance degradation during peak loads.
- Designing cluster topologies with appropriate host count and redundancy to support high availability without over-provisioning.
- Integrating virtualization platforms with existing directory services for role-based access control and audit logging.
- Planning storage architectures using shared vs. local storage based on VM mobility, backup requirements, and cost constraints.
- Assessing hardware compatibility and firmware requirements for virtualization support, including BIOS/UEFI settings and NIC offloading features.
Module 2: Hypervisor Deployment and Configuration Management
- Standardizing hypervisor installation using automated deployment tools (e.g., PXE, kickstart, or host profiles) to ensure configuration consistency.
- Configuring VLAN trunking and virtual switch policies to align with network segmentation and security requirements.
- Implementing host lockdown mode and secure boot to reduce attack surface while maintaining operational access for maintenance.
- Managing firmware and patch baselines across hypervisor hosts using centralized update managers and maintenance windows.
- Setting up time synchronization via NTP across all hosts to prevent VM clock drift and log inconsistency.
- Allocating reserved CPU and memory resources for management VMs to ensure platform stability under load.
Module 3: Virtual Machine Lifecycle and Resource Management
- Defining VM naming conventions and metadata tagging strategies to support inventory tracking and chargeback/reporting systems.
- Right-sizing VMs during provisioning based on application profiling and historical usage data to prevent resource waste.
- Implementing VM templates and guest customization specifications to accelerate deployment and enforce compliance.
- Managing VM snapshots by establishing retention policies to avoid performance degradation and storage bloat.
- Orchestrating VM migrations (vMotion, cold migration) during maintenance with minimal application disruption.
- Decommissioning VMs through formal workflows that include storage reclamation and audit logging.
Module 4: Storage Virtualization and Performance Optimization
- Choosing between thick and thin provisioning based on storage capacity planning and risk of over-allocation.
- Configuring storage I/O control to prioritize critical VMs during contention periods on shared datastores.
- Integrating with storage arrays that support VAAI to offload cloning, zeroing, and snapshot operations.
- Monitoring datastore latency and queue depth to identify bottlenecks and plan capacity expansion.
- Implementing storage DRS to balance VM placement and I/O load across datastores in a cluster.
- Designing backup storage workflows that account for VM snapshot impact on storage performance and consistency.
Module 5: Network Virtualization and Security Integration
- Configuring distributed virtual switches to support consistent network policies across multiple hosts.
- Implementing port groups with VLAN tagging and security policies (promiscuous mode, MAC spoofing) aligned with compliance standards.
- Integrating virtual firewalls or micro-segmentation tools to enforce east-west traffic controls between VMs.
- Planning for network bandwidth allocation using traffic shaping and NIC teaming policies.
- Managing virtual machine network connectivity during live migrations across different subnets.
- Coordinating with network operations teams to ensure physical switch configurations support virtual network requirements.
Module 6: High Availability, Fault Tolerance, and Disaster Recovery
- Configuring host failure response policies in clusters to balance VM restart priority and resource availability.
- Implementing VM-level fault tolerance only for mission-critical workloads due to resource and licensing costs.
- Designing backup strategies that include application-consistent snapshots using VSS or equivalent tools.
- Testing failover procedures for DR sites using isolated recovery networks to validate connectivity and IP addressing.
- Aligning RPO and RTO requirements with replication frequency and VM priority in replication jobs.
- Documenting and maintaining runbooks for manual recovery when automated failover mechanisms fail.
Module 7: Monitoring, Capacity Planning, and Cost Management
- Selecting monitoring tools that correlate hypervisor, guest OS, and application performance metrics.
- Establishing baseline performance thresholds for CPU, memory, disk, and network to detect anomalies.
- Forecasting capacity needs using trend analysis of VM growth and resource consumption over time.
- Identifying and reclaiming stranded resources from orphaned VMs, snapshots, and unattached disks.
- Generating chargeback or showback reports using resource usage data to inform budget decisions.
- Integrating virtualization metrics into enterprise ITSM platforms for incident and problem management.
Module 8: Governance, Compliance, and Operational Policies
- Developing VM provisioning approval workflows to prevent shadow IT and enforce standard configurations.
- Enforcing encryption policies for VMs handling sensitive data, including at-rest and in-transit requirements.
- Conducting regular access reviews for administrative accounts on virtualization platforms.
- Aligning virtualization configurations with regulatory standards such as PCI-DSS, HIPAA, or GDPR.
- Documenting and auditing changes to virtual network and storage configurations for compliance audits.
- Establishing retention policies for VM logs and configuration backups to meet legal and operational requirements.
