Virtualization Course

Lesson 1 • Virtualization vs. Cloud Computing

Clarifies the relationship and differences between virtualization and cloud services. Positions virtualization as the enabling layer beneath cloud platforms.

Lesson 2 • Types of Virtualization

Surveys server, desktop, network, storage, and application virtualization. Helps students select the right virtualization type for a given scenario.

Lesson 3 • What Virtualization Is and Why It Matters

Defines virtualization and contrasts it with bare-metal computing. Establishes the business and technical motivations that drive adoption.

Lesson 1 • Type 2 Hosted Hypervisors

Describes hypervisors that run atop a host operating system and their trade-offs. Connects to Type 1 by highlighting overhead and use-case differences.

Lesson 2 • CPU Virtualization Techniques

Covers full virtualization, paravirtualization, and hardware-assisted virtualization. Explains how each technique handles privileged CPU instructions.

Lesson 3 • Hypervisor Security Boundaries

Examines the attack surface of hypervisors and isolation enforcement mechanisms. Prepares students to evaluate security risks before deploying virtual environments.

Lesson 4 • Type 1 Bare-Metal Hypervisors

Explains how bare-metal hypervisors run directly on hardware without a host OS. Covers scheduling, memory management, and hardware access in this model.

Lesson 1 • VM Migration and Portability

Introduces cold migration, live migration, and cross-platform portability standards. Demonstrates how VMs move between hosts without service interruption.

Lesson 2 • VM Templates and Cloning

Covers building reusable VM templates and performing full or linked clones. Accelerates deployment workflows introduced in the creation section.

Lesson 3 • VM Retirement and Resource Reclamation

Covers decommissioning VMs safely and reclaiming storage, CPU, and memory. Completes the lifecycle loop started in the creation section.

Lesson 4 • Creating and Configuring Virtual Machines

Walks through VM provisioning, hardware profile selection, and OS installation. Establishes baseline skills required for all subsequent VM operations.

Lesson 1 • Network Isolation and Security Policies

Applies firewall rules, traffic shaping, and port security to virtual networks. Builds on VLAN segmentation to enforce network-level access control.

Lesson 2 • VLANs in Virtual Environments

Demonstrates VLAN tagging, trunking, and segmentation within virtual switches. Extends physical VLAN concepts to software-defined network boundaries.

Lesson 3 • Virtual Network Adapters

Covers virtual NIC types, driver models, and their performance characteristics. Connects adapter selection to overall VM network throughput.

Lesson 4 • Troubleshooting Virtual Network Issues

Provides a systematic approach to diagnosing connectivity failures in virtual networks. Applies all prior networking concepts to real-world fault scenarios.

Lesson 1 • Storage I/O Control and Performance

Introduces I/O prioritisation, latency monitoring, and storage QoS policies. Ensures critical VMs receive adequate storage bandwidth under contention.

Lesson 2 • Virtual Disk Formats and Types

Compares thin, thick, and sparse virtual disk formats and their trade-offs. Establishes storage fundamentals needed for all VM provisioning tasks.

Lesson 3 • Backup and Recovery for Virtual Storage

Covers snapshot-based backup, changed block tracking, and recovery point objectives. Completes storage management by addressing data protection requirements.

Lesson 4 • Datastore Management and Capacity Planning

Teaches creating, expanding, and monitoring datastores to prevent capacity issues. Applies disk format knowledge to real-world storage lifecycle management.

Lesson 1 • Diagnosing and Resolving Contention

Provides a structured methodology for identifying CPU, memory, and I/O contention. Applies all resource management concepts to resolve real performance problems.

Lesson 2 • Memory Resource Management

Covers memory shares, ballooning, swapping, and transparent page sharing. Connects memory controls to overall host stability under overcommitment.

Lesson 3 • CPU Resource Allocation and Scheduling

Explains vCPU assignment, CPU shares, reservations, and limits. Provides the control mechanisms needed to prioritise workloads on shared hosts.

Lesson 4 • Performance Monitoring and Metrics

Introduces key performance indicators and monitoring tools for virtual environments. Enables data-driven decisions for tuning and capacity planning.

Lesson 1 • High Availability Cluster Concepts

Explains HA cluster architecture, heartbeat mechanisms, and admission control. Establishes the foundation for all failover and recovery configurations.

Lesson 2 • Distributed Resource Scheduling

Introduces automated load balancing across cluster hosts using DRS policies. Connects resource management skills to cluster-wide workload optimisation.

Lesson 3 • Fault Tolerance and Continuous Availability

Covers synchronous VM mirroring for zero-downtime protection of critical workloads. Extends HA concepts to applications that cannot tolerate any interruption.

Lesson 4 • Disaster Recovery Planning and Design

Covers RPO, RTO, site replication strategies, and DR runbook creation. Provides the planning framework needed before implementing any DR solution.

Lesson 1 • Audit Logging and Compliance Monitoring

Configures audit logs, SIEM integration, and compliance dashboards for virtual environments. Provides evidence required by regulatory and internal audit processes.

Lesson 2 • Vulnerability Management in Virtual Environments

Covers VM vulnerability scanning, patch prioritisation, and remediation workflows. Completes the security lifecycle by addressing ongoing threat exposure.

Lesson 3 • Securing the Hypervisor Layer

Covers hypervisor hardening, patch management, and minimal attack surface principles. Protects the foundational layer on which all VMs depend.

Lesson 4 • VM Isolation and Multi-Tenancy Security

Explains how to enforce strong isolation between tenant VMs on shared infrastructure. Builds on hypervisor security to address multi-tenant risk scenarios.
