This curriculum spans the technical breadth of a multi-phase VDI deployment engagement, covering design, integration, and operational practices comparable to those required in enterprise virtualization programs.
Module 1: Architecture Design and Sizing for VDI Environments
- Selecting between persistent and non-persistent desktop pools based on user profile requirements and storage cost implications.
- Calculating host server requirements (CPU, RAM, disk IOPS) using user workload profiles and concurrency ratios.
- Determining the optimal hypervisor placement for connection brokers and desktop VMs to minimize latency and network hops.
- Designing network segmentation for VDI traffic, including separation of management, user, and storage networks.
- Planning for high availability of critical VDI components such as connection brokers and database servers.
- Integrating load balancing mechanisms for Horizon Connection Server or Citrix Delivery Controllers in multi-site deployments.
Module 2: Hypervisor Integration and Optimization
- Configuring CPU and memory resource pools to prevent VM sprawl and ensure fair allocation across desktop workloads.
- Implementing VM-Host affinity rules to distribute virtual desktops across physical hosts for fault tolerance.
- Enabling and tuning hypervisor-level features such as memory overcommit and transparent page sharing with performance monitoring.
- Deploying virtual desktop templates with optimized guest OS settings (e.g., disabling visual effects, defragmentation).
- Configuring virtual machine snapshots for patching workflows while avoiding performance degradation in production.
- Integrating vSphere DRS or Hyper-V Cluster Shared Volumes for dynamic load distribution and storage failover.
Module 3: Desktop Image Management and Golden Image Lifecycle
- Establishing a change control process for golden image updates, including testing in a staging environment.
- Choosing between full clone and linked clone strategies based on storage efficiency and patching frequency.
- Using tools like VMware Instant Clone or Citrix Machine Creation Services to reduce provisioning time.
- Integrating Microsoft SCCM or Intune with VDI image builds to ensure consistent application and policy deployment.
- Managing driver injection for diverse endpoint devices (zero clients, thin clients, laptops) in the base image.
- Implementing version control and rollback procedures for desktop images using image naming and tagging standards.
Module 4: User Profile and Data Management
- Selecting profile management solutions (FSLogix, UE-V, or native roaming profiles) based on application compatibility and roaming needs.
- Configuring profile container storage on high-performance file shares or Azure Files with appropriate access controls.
- Excluding specific registry hives or folders from profile persistence to prevent bloat and login delays.
- Implementing folder redirection for Documents, Desktop, and AppData to centralized file servers or OneDrive.
- Planning for concurrent user sessions and profile conflicts in shared or task-worker environments.
- Monitoring profile size growth and enforcing quotas to prevent storage overruns and login performance issues.
Module 5: Network Optimization and Display Protocol Configuration
- Tuning display protocol settings (PCoIP, Blast Extreme, HDX) for varying bandwidth and latency conditions.
- Configuring QoS policies on network infrastructure to prioritize VDI traffic over other applications.
- Deploying WAN optimization or SD-WAN solutions for remote users accessing VDI from branch offices.
- Setting up adaptive codec selection based on client device capabilities and network conditions.
- Limiting USB redirection and clipboard sharing to reduce bandwidth consumption and security exposure.
- Monitoring round-trip time and frame rate metrics to identify and troubleshoot user experience degradation.
Module 6: Security, Access Control, and Endpoint Management
- Enforcing multi-factor authentication for VDI access using RADIUS or SAML integration with identity providers.
- Configuring role-based access control (RBAC) for administrative tasks in Horizon or Citrix Studio consoles.
- Implementing client-side certificate authentication for thin client devices connecting to VDI brokers.
- Applying host-based firewall rules on virtual desktops to restrict outbound traffic to approved services.
- Integrating endpoint detection and response (EDR) agents into desktop images without impacting boot performance.
- Disabling local USB storage and printer redirection in high-security environments based on compliance requirements.
Module 7: Monitoring, Logging, and Performance Troubleshooting
- Deploying centralized logging for VDI components using tools like Splunk or ELK to correlate events across layers.
- Setting up performance baselines for login duration, boot time, and session responsiveness per user group.
- Using synthetic transactions to simulate user logins and detect broker or agent failures proactively.
- Interpreting hypervisor-level metrics (CPU ready time, memory ballooning) to identify resource contention.
- Diagnosing display latency issues by analyzing protocol-specific performance counters and packet captures.
- Creating automated alerts for critical thresholds such as connection broker service downtime or datastore full conditions.
Module 8: Scalability, Disaster Recovery, and Cloud Integration
- Designing a scalable connection broker farm with DNS round-robin or GSLB for global VDI deployments.
- Implementing automated desktop provisioning and de-provisioning based on user demand and schedule.
- Configuring replication of virtual desktop VMs and profile stores to a secondary data center for failover.
- Integrating Azure Virtual Desktop or AWS WorkSpaces with on-premises VDI for hybrid burst capacity.
- Testing disaster recovery runbooks that include reconnection of user sessions and reauthentication workflows.
- Managing licensing portability across on-premises and cloud-hosted virtual desktop instances.
