This curriculum spans the technical breadth and operational rigor of a multi-phase VDI deployment engagement, comparable to an enterprise infrastructure team’s end-to-end planning, integration, and governance workflow across hypervisors, access layers, security frameworks, and disaster recovery systems.
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.
- Determining host-to-VM density ratios while accounting for CPU overcommitment policies and memory ballooning risks.
- Designing network segmentation for VDI traffic, including separation of management, user, and storage networks to reduce latency and improve security.
- Calculating IOPS requirements for boot, logon, and peak usage storms using real-world user workload modeling.
- Choosing hypervisor-specific features (e.g., VMware vSphere HA vs. Hyper-V Failover Clustering) for desktop resilience.
- Planning for scalability by defining thresholds that trigger horizontal expansion of connection brokers or desktop hosts.
Module 2: Hypervisor and Infrastructure Integration
- Configuring VM hardware versions and paravirtualized drivers to optimize performance across hypervisor platforms.
- Implementing storage tiering policies using SSD caching or all-flash arrays for VDI workloads with high random read/write demands.
- Integrating VDI hosts with centralized monitoring tools (e.g., vCenter, SCOM) to track resource contention and VM health.
- Aligning VM snapshot policies with backup windows while avoiding performance degradation during snapshot consolidation.
- Enabling CPU and memory resource reservations for critical desktops to prevent resource starvation during peak loads.
- Validating VM live migration compatibility across clusters with differing CPU generations or firmware levels.
Module 3: Connection Broker and Access Layer Configuration
- Deploying load-balanced connection brokers (e.g., VMware Horizon Connection Server, Citrix Delivery Controller) in active-passive or active-active mode.
- Configuring secure remote access via Unified Access Gateway or Citrix Gateway with TLS 1.2+ and certificate rotation policies.
- Mapping user groups to desktop pools using Active Directory security groups and GPO-based targeting.
- Setting up smart card or RADIUS-based authentication for regulated environments requiring two-factor access.
- Defining display protocol policies (e.g., PCoIP, Blast Extreme, HDX) based on bandwidth constraints and multimedia requirements.
- Implementing session timeout and reconnection rules to manage idle desktops and license consumption.
Module 4: Image Management and Golden Image Lifecycle
- Designing a layered image strategy using tools like VMware Dynamic Environment Manager or Citrix App Layering to separate OS, apps, and user settings.
- Scheduling regular recomposition of non-persistent desktops to apply OS patches and application updates.
- Managing driver injection for diverse endpoint devices (zero clients, thin clients, laptops) within a single golden image.
- Validating application compatibility in the golden image under concurrent multi-user conditions.
- Implementing version control and rollback procedures for golden images using image repositories and change logs.
- Reducing image bloat by removing unnecessary services, background processes, and default applications.
Module 5: User Profile and Data Management
- Selecting between roaming profiles, FSLogix, or UE-V based on profile size, login time, and application compatibility.
- Configuring profile container locations on high-performance file shares with appropriate NTFS permissions and quotas.
- Excluding temporary and cache directories from profile synchronization to reduce logon/logoff times.
- Implementing folder redirection for Documents, Desktop, and AppData to central storage with offline access via OneDrive or DFS.
- Planning for profile corruption by defining automated backup and restore procedures during login failures.
- Monitoring profile growth trends to enforce cleanup policies and prevent storage overruns.
Module 6: Security, Compliance, and Access Governance
- Enforcing encryption of VDI traffic using TLS for broker communication and AES for display protocols.
- Applying least-privilege access controls to administrative consoles and restricting console access to jump hosts.
- Integrating VDI events with SIEM systems for audit logging and anomaly detection (e.g., multiple failed logins).
- Configuring anti-virus exclusions for VDI-specific processes to prevent performance bottlenecks without reducing protection.
- Implementing data loss prevention (DLP) policies to restrict clipboard, USB, and print redirection based on user role.
- Aligning VDI configurations with regulatory standards (e.g., HIPAA, GDPR) for data residency and access logging.
Module 7: Monitoring, Performance Tuning, and Troubleshooting
- Deploying end-user experience monitoring tools (e.g., VMware User Environment Manager Troubleshooting Tool, Citrix Director) to diagnose login delays.
- Correlating hypervisor metrics (CPU ready, memory ballooning) with user-reported performance issues.
- Using display protocol telemetry to identify bandwidth constraints and adjust image quality settings.
- Establishing baseline performance metrics for login duration, application launch time, and I/O latency.
- Conducting root cause analysis on desktop provisioning failures by reviewing logs from brokers, hypervisors, and image stores.
- Optimizing storage performance by adjusting disk alignment, enabling UNMAP, and tuning storage queue depth.
Module 8: Business Continuity and Disaster Recovery Planning
- Defining RPO and RTO for VDI components and aligning replication strategies (e.g., SRDF, vSphere Replication) accordingly.
- Replicating connection brokers and databases to a secondary site with automated DNS or GSLB failover.
- Testing failover procedures for desktop pools by redirecting users to a standby data center without data loss.
- Storing golden images and configuration backups in geographically separate locations with version retention policies.
- Coordinating VDI recovery with dependent systems such as Active Directory, DNS, and certificate authorities.
- Documenting manual recovery steps for scenarios where automated failover mechanisms are unavailable or compromised.
