This curriculum spans the equivalent depth and breadth of a multi-workshop technical engagement for designing, operating, and scaling enterprise VDI environments, addressing the same architectural, operational, and security decisions faced during large-scale deployments.
Module 1: Architecture Design and Sizing for VDI Environments
- Selecting between persistent and non-persistent desktop pools based on user profile requirements and IT support capacity.
- Calculating concurrent user density per host based on CPU, memory, and storage IOPS constraints under peak load conditions.
- Designing network segmentation for VDI traffic, including separation of management, user, and storage networks to reduce latency and improve security.
- Choosing hypervisor-specific features such as VMware vGPU, NVIDIA GRID, or Microsoft RemoteFX based on application graphics demands.
- Planning for high availability by configuring vSphere HA, DRS, or Hyper-V Failover Clustering with appropriate restart priorities.
- Integrating load balancers for connection brokers to distribute user logins evenly across multiple broker servers during peak login storms.
Module 2: Image Management and Golden Image Lifecycle
- Establishing a change control process for golden image updates to prevent configuration drift across desktop deployments.
- Using tools like VMware Horizon Composer or Microsoft FSLogix to manage layered images and minimize storage footprint.
- Implementing application packaging standards (MSI, App-V) to ensure compatibility and reduce conflicts during image updates.
- Scheduling regular patching cycles for base images while maintaining rollback capabilities via snapshot or backup.
- Managing driver injection for diverse endpoint hardware to ensure peripheral compatibility across thin and zero clients.
- Testing image performance using synthetic workloads to validate boot time and login duration before production rollout.
Module 3: User Profile and Data Management
- Choosing between roaming profiles, FSLogix, or UE-V based on application compatibility and profile size constraints.
- Configuring profile container storage on high-performance file shares with appropriate NTFS permissions and quotas.
- Implementing profile exclusion rules to prevent bloating from temporary files and cache directories.
- Monitoring profile load times and troubleshooting delays caused by large registry hives or network latency.
- Designing backup and recovery procedures for user profile containers to support disaster recovery scenarios.
- Enforcing profile size limits and alerting administrators when thresholds are exceeded to maintain system stability.
Module 4: Storage Optimization and Performance Tuning
- Selecting storage tiering strategies using SSDs for write-intensive operations like boot storms and link-clones.
- Configuring storage replication and deduplication settings to balance performance and capacity in all-flash arrays.
- Monitoring storage latency and IOPS per VM to identify bottlenecks during peak usage periods.
- Implementing storage quality of service (QoS) policies to prioritize critical desktop workloads over non-essential VMs.
- Planning for thin provisioning with headroom to avoid out-of-space conditions during unexpected growth.
- Using storage analytics tools to forecast capacity needs and justify hardware refresh cycles based on utilization trends.
Module 5: Connection Broker and Access Infrastructure
- Configuring secure LDAP or SAML authentication between connection brokers and identity providers for single sign-on.
- Deploying multiple connection broker instances in a farm with health monitoring and automatic failover.
- Setting up secure gateway or Unified Access Gateway (UAG) appliances for external user access with TLS inspection.
- Managing certificate lifecycle for broker servers and gateways to prevent authentication outages.
- Implementing IP affinity or session persistence to maintain consistent user-to-VM mappings when required.
- Monitoring connection success rates and troubleshooting authentication failures using broker logs and event tracing.
Module 6: Security, Compliance, and Endpoint Hardening
- Applying desktop VM security baselines (e.g., CIS benchmarks) to meet regulatory compliance requirements.
- Disabling unnecessary services and ports on VDI guests to reduce attack surface and improve patching efficiency.
- Enforcing encryption for desktop VMs at rest using BitLocker or vSphere VM encryption.
- Integrating endpoint detection and response (EDR) agents with exclusion rules to avoid performance impact on VDI hosts.
- Configuring group policies to restrict clipboard redirection, file transfer, and printing based on user role.
- Conducting regular vulnerability scans on desktop images and remediating findings before image promotion.
Module 7: Monitoring, Logging, and Performance Troubleshooting
- Deploying monitoring agents on VDI hosts and desktops to collect CPU, memory, and disk metrics for trend analysis.
- Setting up alerts for high logon duration, session drops, or broker unresponsiveness using tools like vRealize or SCOM.
- Correlating user complaints with infrastructure metrics to isolate issues to network, storage, or application layers.
- Using synthetic transactions to simulate user logins and detect performance degradation before user impact.
- Centralizing logs from brokers, connection servers, and desktops using SIEM or log aggregation platforms.
- Creating standardized runbooks for common issues such as failed logons, black screens, or printer mapping failures.
Module 8: Business Continuity and Scalability Planning
- Designing a VDI failover site with replicated desktop images and broker configuration for disaster recovery.
- Testing DR runbooks annually to validate RTO and RPO targets for critical user groups.
- Implementing auto-scaling policies for cloud-hosted VDI (e.g., Azure Virtual Desktop) based on user demand.
- Managing licensing mobility across on-premises and cloud environments to avoid compliance violations.
- Planning for seasonal workload spikes by pre-staging additional desktops or enabling burst-to-cloud capacity.
- Documenting dependencies between VDI components and third-party services (e.g., DNS, DHCP, PKI) for incident response.
