This curriculum spans the equivalent of a multi-phase VDI migration advisory engagement, covering technical and operational considerations from initial assessment through disaster recovery, comparable to the scope of an enterprise-wide virtual desktop transformation program.
Module 1: Assessment and Readiness Evaluation
- Conduct inventory audits of existing physical and virtual desktops to determine application compatibility with target VDI platform.
- Profile user workloads by department to classify desktop requirements into knowledge worker, task worker, and power user categories.
- Evaluate network latency and bandwidth between user locations and data centers to identify sites unsuitable for centralized VDI.
- Assess storage IOPS requirements during peak boot and login storms using historical performance data from current desktops.
- Determine licensing eligibility for Windows client operating systems under VDI scenarios based on existing Microsoft volume licensing agreements.
- Engage application owners to test critical line-of-business applications in non-production VDI environments for rendering and performance issues.
Module 2: Architecture Design and Sizing
- Select between persistent and non-persistent desktop pools based on user personalization needs and IT support overhead tolerance.
- Size connection broker infrastructure to handle concurrent user logins, factoring in failover capacity and geographic distribution.
- Design storage tiering strategy using SSD and HDD arrays to balance cost and performance for OS, user profile, and application layers.
- Calculate GPU requirements for engineering and design users and decide between physical GPU passthrough and virtual GPU (vGPU) allocation.
- Define network VLAN segmentation and QoS policies to prioritize PCoIP, Blast, or RDP traffic over WAN links.
- Architect high availability for critical VDI components including brokers, gateways, and database servers using clustering or load balancing.
Module 3: Image Management and Golden Image Strategy
- Establish a change control process for golden image updates, including testing cycles and rollback procedures.
- Decide between full image cloning and layering technologies (e.g., App Layering, FSLogix) based on application delivery complexity.
- Integrate golden image builds into CI/CD pipelines using automation tools like HashiCorp Packer or VMware Image Builder.
- Implement driver management strategy to support diverse endpoint devices accessing the same base image.
- Define patching cadence for OS and security updates within golden images, balancing compliance and stability.
- Optimize image size by removing unnecessary components and pre-installing common software to reduce provisioning time.
Module 4: User Profile and Data Management
- Deploy profile containerization using FSLogix or UE-V to ensure consistent user experience across non-persistent desktops.
- Configure OneDrive and Teams redirection policies to minimize profile bloat and improve logon performance.
- Establish file share access controls and quotas for redirected folders (Documents, Desktop, AppData).
- Design profile backup and recovery procedures for disaster scenarios involving profile store corruption.
- Implement exclusion rules for large or frequently changing files in profile containers to prevent performance degradation.
- Evaluate on-premises versus cloud-based profile storage based on latency, cost, and data sovereignty requirements.
Module 5: Security and Access Control
- Enforce multi-factor authentication for external access via VDI gateways using RADIUS or SAML integration.
- Configure role-based access control (RBAC) in the VDI console to limit administrative privileges to specific desktop pools.
- Implement endpoint compliance checks through NAC or conditional access policies before allowing broker connections.
- Apply Just Enough Administration (JEA) principles to limit PowerShell and console access for support staff.
- Encrypt desktop images and profile stores at rest using platform-native or third-party encryption tools.
- Integrate VDI session logging with SIEM systems to detect anomalous user behavior or data exfiltration attempts.
Module 6: Network and Performance Optimization
- Select display protocol (PCoIP, Blast Extreme, HDX) based on WAN conditions, client device capabilities, and security posture.
- Deploy WAN optimization appliances or SD-WAN solutions to reduce latency and packet loss for remote users.
- Configure adaptive transport settings to dynamically switch between UDP and TCP based on network quality.
- Implement client-side rendering for multimedia content to reduce server CPU and bandwidth consumption.
- Monitor and tune MTU settings across network paths to prevent fragmentation in UDP-based display protocols.
- Establish baseline performance metrics for login duration, application launch time, and input responsiveness for SLA tracking.
Module 7: Monitoring, Support, and Lifecycle Management
- Deploy synthetic transaction monitoring to simulate user logins and detect broker or infrastructure failures.
- Configure alerts for storage latency spikes, connection broker queue depth, and VM power state anomalies.
- Integrate VDI event logs with existing ITSM platforms to automate incident ticket creation for common failures.
- Develop escalation paths for resolving issues involving multiple domains (network, storage, AD, VDI).
- Plan desktop refresh cycles to phase out older VM hardware versions and maintain hypervisor compatibility.
- Conduct quarterly capacity reviews to adjust host, storage, and license allocations based on usage trends.
Module 8: Business Continuity and Disaster Recovery
- Define RPO and RTO for VDI workloads and align replication frequency of desktop VMs and profile stores accordingly.
- Replicate critical VDI components (brokers, databases, connection servers) to secondary site with automated DNS failover.
- Test failover procedures for non-persistent desktop pools, ensuring image repositories are accessible at DR site.
- Validate user profile replication consistency between primary and secondary file servers.
- Document manual connection procedures for users to access desktops during automated broker failover delays.
- Include VDI in enterprise-wide backup validation exercises to confirm recoverability of configuration databases.
