Use Case
VDI Implementation for a Regulated Financial Organization
Empower. Secure. Scale.
— Seamless Remote Access for Compliance-Driven Environments
The Client
A regulated enterprise operating across multiple data centers and business units in Hong Kong. The organization required a strategic revamp of its legacy Microsoft Exchange and Active Directory (AD) infrastructure to support hybrid cloud adoption, improve operational resilience, and meet evolving compliance standards.
The Challenge
The organization’s legacy Citrix-based remote access infrastructure was nearing end-of-life and lacked the agility and performance needed for modern work scenarios. Key challenges included:
-
Limited scalability and performance for concurrent users
-
Complex management and high operational overhead
-
Inadequate support for modern authentication and user personalization
-
Need for seamless migration with minimal disruption to operations
The goal was to implement a next-generation VDI platform that supports secure remote access, improves user experience, and integrates with existing infrastructure.
The Solution
Amidas proposed and implemented Omnissa Horizon, a VMware-powered VDI solution tailored to the client’s operational and compliance needs.
Scope of Work
-
Provisioned infrastructure to support 700 concurrent Virtual Desktops (VDs) and 700 concurrent Virtual Applications (VAs), scalable to 1,200
-
Deployed Horizon components including Connection Server, Unified Access Gateway (UAG), Enrollment Server, Dynamic Environment Manager (DEM), and Edge Gateway
-
Configured desktops with 4 vCPUs, 16GB RAM, and 500GB SSD storage, running Windows 11 Pro
-
Integrated FSLogix for persistent user profiles and ADFS SAML SSO for secure authentication with MFA
-
Enabled secure remote access without VPN using UAG
-
Leveraged existing server hardware and vSphere infrastructure to minimize cost
