This curriculum spans the technical and operational rigor of a multi-workshop infrastructure modernization program, addressing the same architectural, security, and performance challenges encountered in large-scale VDI deployments across hybrid environments.

Module 1: Architecture Design and Sizing

  • Selecting between persistent and non-persistent desktop pools based on user profile complexity and data retention requirements.
  • Calculating vCPU-to-user ratios while accounting for peak concurrency and application CPU bursts in knowledge worker environments.
  • Determining storage IOPS requirements using boot, logon, and steady-state workload profiles across user personas.
  • Choosing between full clone, linked clone, and instant clone provisioning based on scalability, patching frequency, and storage efficiency.
  • Designing network segmentation for management, user, and storage traffic to isolate latency-sensitive protocols like PCoIP or Blast Extreme.
  • Integrating load balancer placement and SSL offloading strategies for connection brokers in multi-datacenter deployments.

Module 2: Image Management and Golden Image Lifecycle

  • Establishing a change control process for golden image updates that includes regression testing for critical line-of-business applications.
  • Implementing layered image architectures using App Layering or FSLogix to decouple OS, platform, and application updates.
  • Scheduling recompose operations during maintenance windows to minimize user disruption in non-persistent environments.
  • Managing driver injection for diverse endpoint hardware while avoiding image bloat from unnecessary drivers.
  • Enforcing antivirus and patch compliance within the base image before deployment to downstream pools.
  • Version-controlling golden images using automated build pipelines and hash verification to ensure consistency across regions.

Module 3: Storage Optimization and Performance Engineering

  • Allocating tiered storage (SSD/HDD) based on read/write intensity of user workloads and profile behavior.
  • Configuring storage replication and deduplication ratios without introducing latency that impacts login storms.
  • Implementing write-cache sizing on shared storage to absorb burst I/O during peak logon periods.
  • Monitoring and tuning storage queue depths to prevent bottlenecks in all-flash arrays supporting VDI workloads.
  • Deploying host-based caching (e.g., VMware vSphere Flash Read Cache) with capacity planning for cache miss scenarios.
  • Aligning VM virtual disk types (thick vs. thin) with storage array capabilities and overprovisioning policies.

Module 4: User Experience and Profile Management

  • Choosing between roaming profiles, UE-V, and FSLogix based on application compatibility and mailbox integration needs.
  • Configuring folder redirection for Documents, Desktop, and AppData to reduce profile size and improve logon times.
  • Setting up FSLogix profile container size limits and exclusion rules to prevent container bloat from temporary files.
  • Monitoring and troubleshooting profile corruption events through event log correlation and container health checks.
  • Optimizing logon duration by pre-loading commonly used applications during idle periods using group policy or scripts.
  • Managing application-specific settings synchronization conflicts in multi-session environments using exclusion lists.

Module 5: Security, Compliance, and Access Control

  • Enforcing multi-factor authentication for external access to Horizon or Citrix Gateway with conditional access policies.
  • Implementing role-based access control (RBAC) for VDI admin consoles to separate provisioning, monitoring, and support functions.
  • Configuring antivirus exclusions for hypervisor and broker processes without compromising endpoint protection.
  • Applying Just Enough Administration (JEA) principles to limit local admin rights on virtual desktops.
  • Encrypting desktop VMs at rest using VM-level encryption or storage array-based mechanisms in regulated environments.
  • Auditing user access and session activity through SIEM integration with connection broker and hypervisor logs.

Module 6: Monitoring, Troubleshooting, and Performance Tuning

  • Deploying synthetic transactions to simulate user logons and detect performance degradation before end-user impact.
  • Correlating hypervisor CPU ready time with desktop responsiveness metrics to identify resource contention.
  • Using protocol-specific analytics (e.g., Citrix HDX Monitor, VMware PCoIP logs) to isolate network or rendering issues.
  • Establishing baseline thresholds for logon duration, frame rate, and latency to trigger proactive alerts.
  • Diagnosing storage latency spikes by analyzing datastore latency metrics alongside VM-level disk queue lengths.
  • Documenting root cause analysis workflows for common issues such as black screen, session drops, or printer mapping failures.

Module 7: Business Continuity and Scalability Planning

  • Designing cross-site broker failover with DNS or GSLB to maintain connection broker availability during outages.
  • Replicating desktop VMs between data centers using asynchronous replication while managing RPO and storage overhead.
  • Testing disaster recovery runbooks that include recomposing desktop pools from golden images at the recovery site.
  • Scaling connection brokers horizontally with health checks and dynamic registration to handle increased connection loads.
  • Planning for surge capacity using cloud-hosted desktops (e.g., Azure Virtual Desktop) with hybrid identity integration.
  • Validating backup strategies for user profile containers and application data with recovery time objectives (RTO) testing.

Module 8: Cost Management and License Optimization

  • Negotiating Microsoft Windows VDA and RDS CAL licensing based on user count versus device count models.
  • Tracking VMware Horizon or Citrix Virtual Apps and Desktops license consumption to avoid over-deployment.
  • Right-sizing VMs using performance telemetry to reclaim underutilized CPU and memory allocations.
  • Implementing power policy schedules to power off idle desktops during non-business hours.
  • Comparing on-premises TCO with cloud-hosted VDI using reserved instances versus pay-as-you-go pricing models.
  • Enforcing desktop session timeouts and disconnect policies to reduce active VM count and associated licensing costs.
