This curriculum spans the equivalent of a multi-workshop technical design engagement, covering the full lifecycle of VDI infrastructure planning, deployment, and operations as typically addressed in enterprise architecture and internal capability-building programs.

Module 1: VDI Architecture and Deployment Models

  • Select between persistent and non-persistent desktop pools based on user profile requirements and storage cost implications.
  • Decide on on-premises, cloud-hosted, or hybrid VDI deployment considering data residency, latency, and operational control needs.
  • Evaluate connection broker technologies (e.g., VMware Horizon Connection Server, Citrix Delivery Controller) for scalability and integration with existing identity systems.
  • Size the control plane components to handle peak concurrent login storms during morning boot-up periods.
  • Implement high availability for critical VDI infrastructure components such as brokers and gateways using clustering or failover configurations.
  • Integrate VDI with existing Active Directory and DNS infrastructure to ensure seamless user authentication and name resolution.

Module 2: Compute Resource Planning and Sizing

  • Calculate vCPU-to-user ratios based on application workloads, distinguishing between knowledge workers and power users.
  • Allocate memory per virtual desktop with overhead for OS, hypervisor, and VDI agent processes included in calculations.
  • Implement CPU resource reservations or limits to prevent noisy neighbor issues in shared host environments.
  • Choose between full clone and linked clone desktops based on performance requirements and storage efficiency trade-offs.
  • Monitor and adjust overcommit ratios for CPU and memory in response to performance degradation during peak usage.
  • Plan for burst capacity using cloud-hosted desktops during temporary workforce scaling events.

Module 3: Storage Design and Optimization

  • Design storage tiering strategies using SSD and HDD layers to balance IOPS requirements and cost for boot, login, and steady-state operations.
  • Implement storage replication and snapshots for non-persistent desktops to enable rapid recomposition and rollback.
  • Configure storage quality of service (QoS) policies to prioritize I/O for critical desktop pools during high contention.
  • Select between SAN, NAS, or hyper-converged infrastructure based on scalability, latency, and administrative complexity.
  • Size write cache volumes for linked clones to prevent overflow during intensive write operations.
  • Monitor storage latency and IOPS utilization to identify bottlenecks before user impact occurs.

Module 4: Network Infrastructure and Connectivity

  • Design network bandwidth allocation per user based on display protocol (e.g., Blast, PCoIP, HDX) and multimedia usage patterns.
  • Implement QoS policies on network switches and firewalls to prioritize VDI traffic over less critical applications.
  • Configure WAN optimization or SD-WAN for remote branch offices to reduce latency and packet loss for remote desktop access.
  • Segment VDI management, desktop, and user access traffic using VLANs to enhance security and performance.
  • Plan for redundant network paths and NIC teaming on hypervisor hosts to prevent single points of failure.
  • Test and validate display protocol behavior under constrained bandwidth and high-latency conditions.

Module 5: Desktop Image Management and Lifecycle

  • Develop a standardized golden image with OS, applications, and VDI agent components using automated build pipelines.
  • Implement a patching schedule for desktop images that aligns with organizational change control windows.
  • Use layering technologies (e.g., App Layering, FSLogix) to separate OS, applications, and user settings for flexible deployment.
  • Test updated images in a staging environment before rolling out to production desktop pools.
  • Manage version drift across desktop pools by enforcing periodic recomposition or refresh cycles.
  • Retire outdated images and associated storage artifacts to reclaim capacity and reduce management overhead.

Module 6: User Profile and Data Management

  • Deploy profile management solutions (e.g., FSLogix, UE-V) to ensure consistent user environments across non-persistent desktops.
  • Configure profile container size limits and roaming exclusions to prevent excessive storage consumption.
  • Integrate user data redirection to network shares or cloud storage (e.g., OneDrive) to decouple data from desktop lifecycle.
  • Implement backup and recovery procedures for user profile containers and home directories.
  • Monitor profile load times and troubleshoot delays caused by large registry hives or excessive file counts.
  • Enforce encryption for profile containers at rest and in transit to meet compliance requirements.

Module 7: Monitoring, Performance Tuning, and Troubleshooting

  • Deploy monitoring tools (e.g., vRealize Operations, Citrix Director) to track desktop logon duration, latency, and resource utilization.
  • Establish baseline performance metrics for CPU, memory, disk I/O, and network to detect anomalies.
  • Use display protocol telemetry to diagnose user experience issues such as frame rate drops or input lag.
  • Correlate hypervisor, broker, and endpoint logs during incident investigations to isolate root cause.
  • Adjust virtual desktop resource allocation dynamically based on historical usage trends and forecasting.
  • Conduct regular health checks on VDI infrastructure components to preempt failures and performance degradation.

Module 8: Security, Compliance, and Access Governance

  • Enforce multi-factor authentication for external access to VDI environments via unified access gateways or connection brokers.
  • Apply least-privilege principles to administrative access for VDI management consoles and hypervisor hosts.
  • Encrypt virtual desktop disks and profile stores using platform-native or third-party encryption tools.
  • Implement role-based access control (RBAC) to delegate management tasks without granting full administrative rights.
  • Audit user login activity, file access, and administrative changes to meet regulatory logging requirements.
  • Integrate VDI with endpoint detection and response (EDR) solutions to monitor for threats within virtual desktops.
