Caribbean Bank Transitions 850+ Users to Omnissa Horizon with Zero Disruption

Client Profile 

A leading private bank in the Caribbean, serving thousands of customers across multiple branches. The bank relies on fast, secure access to applications and desktops to keep operations running smoothly and deliver great customer service.

Challenges 

• The existing Citrix infrastructure incurred a 25% annual increase in licensing costs, posing a significant financial burden.
• Employees across all branches experienced application loading delays (3-5 minutes), frequent session disconnections, and performance degradation during peak hours, directly impacting daily operations and customer interactions.
• The outdated virtualization platform struggled to meet the demands of modern banking workflows, leading to reduced operational efficiency and potential risks to customer satisfaction and regulatory compliance.
• The IT team faced increasing difficulty maintaining and troubleshooting the complex Citrix environment. Vendor support costs were rising, and resolution times for critical issues exceeded acceptable service levels.
• The organization requires a new VDI solution to deliver consistent performance, reduce operational complexity, and provide a scalable foundation for future digital transformation, including potential hybrid cloud migration.

Anunta’s Solution 

• Anunta designed and executed a migration strategy prioritizing business continuity while modernizing the bank’s entire end-user computing infrastructure.
• The engagement began with a detailed assessment to create a risk-mitigated transition plan, followed by a carefully orchestrated three-phase approach.
• A pilot rollout with 75 users from critical departments helped validate Omnissa Horizon’s performance, ensure user satisfaction, and fine-tune the rollout approach before scaling.
• Omnissa Dynamic Environment Manager (DEM) ensures seamless user profile migration. Anunta addressed complex challenges, including load balancer optimization, App Volume Manager connectivity, and master image standardization.
• Critical components like SSL certificates for secure remote access, True SSO integration, and SAML authentication were methodically configured to maintain security policies.
• Anunta engineers worked closely with the bank’s IT team to establish robust monitoring and management tools.
• To ensure business continuity, both Citrix and Horizon environments operated in parallel. Department-wise migrations were carried out over weekends, with rollback options available until each move was confirmed successful.

Key Benefits

• Transition to a more flexible and scalable Omnissa Horizon VDI platform.
• Implementation of DEM ensures consistent and efficient user profiles.
• Gradual deployment minimizes potential disruptions during migration.
• Addressing initial deployment challenges ensures a stable foundation for the new environment.
• Establishing a platform that can evolve towards hybrid or cloud deployments.
