This curriculum spans the equivalent depth and structure of a multi-workshop operational readiness program, addressing the same technical and procedural rigor applied in enterprise VDI resilience engagements, from dependency mapping and cross-site architecture to automated failover orchestration and compliance-aligned maintenance.
Module 1: Assessing VDI Environment Dependencies and Recovery Requirements
- Map critical dependencies between virtual desktops, connection brokers, identity providers, and backend databases to identify single points of failure.
- Classify desktop workloads by business criticality to define recovery time objectives (RTO) and recovery point objectives (RPO) for each tier.
- Document integration points with enterprise storage arrays, network infrastructure, and endpoint management tools that impact recovery sequencing.
- Validate DNS, DHCP, and time synchronization dependencies across sites to ensure consistent service restoration.
- Inventory third-party applications with local installations or user-specific configurations that may not persist across recovery events.
- Establish ownership roles for desktop images, user profiles, and policy templates to coordinate recovery responsibilities across teams.
Module 2: Designing Multi-Site VDI Architecture for Resilience
- Configure connection broker farms with cross-site load balancing and failover capabilities using DNS round-robin or global server load balancing (GSLB).
- Implement synchronous or asynchronous replication of master image storage repositories based on WAN bandwidth and RPO constraints.
- Deploy redundant Unified Access Gateways or Blast Secure Gateways in active-passive mode across data centers to maintain secure remote access.
- Align virtual desktop resource pools with compute clusters in secondary sites to enable rapid recommissioning during failover.
- Size standby capacity in the recovery site to accommodate peak concurrent login storms post-failover.
- Configure vSphere HA and DRS settings to prevent resource contention during partial outages without triggering unnecessary migrations.
Module 3: Protecting and Replicating VDI-Specific Components
- Schedule application-consistent snapshots of connection broker servers using hypervisor-level backup tools to preserve configuration state.
- Replicate user profile stores using DFS-R or storage-based replication while managing latency impact on logon performance.
- Implement change block tracking (CBT) for linked clone replicas to minimize replication bandwidth during recompose operations.
- Back up Persona Management configuration files and policy GPOs separately from user data to enable independent restoration.
- Test failover of SQL Server instances hosting Horizon View Events or Composer databases under load to validate transaction log replay integrity.
- Encrypt replicated desktop images in transit and at rest when crossing untrusted network zones or cloud boundaries.
Module 4: User Data and Profile Management in Disaster Scenarios
- Enforce mandatory redirection of user data folders (Documents, Desktop) to highly available file shares with continuous availability enabled.
- Configure roaming profile fallback mechanisms to prevent login failures when primary profile servers are unreachable.
- Implement FSLogix profile container failover by attaching VHDX files from replicated Azure Files or SMB shares during site recovery.
- Pre-stage frequently accessed user data in the recovery site using tiered caching or proactive seeding to reduce post-failover latency.
- Define cleanup policies for stale profile containers to prevent uncontrolled storage growth after temporary failover events.
- Monitor profile load times during simulated outages to identify oversized profiles that degrade recovery performance.
Module 5: Orchestrating Failover and Failback Procedures
- Develop runbooks that sequence the activation of connection brokers, domain controllers, and storage gateways in dependency order.
- Modify DNS records or GSLB policies to redirect clients to the recovery site’s connection brokers with minimal TTL windows.
- Re-register desktop agents in the recovery site with the failover connection broker using automated scripts or powercli.
- Validate certificate trust chains for SSL/TLS termination points after IP address changes during site switchover.
- Coordinate failback timing with application teams to avoid conflicts with backend system cutover schedules.
- Re-synchronize user write-back disks or differencing disks after primary site restoration to prevent data loss.
Module 6: Testing and Validating VDI Disaster Recovery Plans
- Conduct tabletop exercises with desktop support, network, and security teams to validate escalation paths during declared outages.
- Execute isolated failover drills using VLAN segmentation to prevent client redirection while testing broker and desktop startup.
- Measure actual RTO by timing from recovery initiation to first successful interactive desktop login in the secondary site.
- Verify peripheral redirection (printers, USB devices) functionality in the recovery environment using representative client devices.
- Test multi-factor authentication workflows with external identity providers to ensure uninterrupted access during failover.
- Document gaps in application availability or performance and adjust replication schedules or resource allocation accordingly.
Module 7: Governance, Compliance, and Ongoing DR Maintenance
- Integrate VDI recovery runbooks into enterprise-wide incident management systems with defined escalation thresholds.
- Track configuration drift between primary and recovery site desktop images using automated comparison tools after patch cycles.
- Enforce change control procedures that require DR impact assessment before modifying connection broker topology or storage layout.
- Archive test results and remediation actions to demonstrate compliance with regulatory requirements during audits.
- Review replication job logs weekly to detect missed backups or latency spikes affecting RPO adherence.
- Update recovery documentation quarterly to reflect changes in IP addressing, firewall rules, or third-party service dependencies.
