Background & Challenges

A leading pharmaceutical company in India improving healthcare with innovation, commitment, and trust. The Company is vertically integrated with the ability to develop, manufacture and market pharmaceutical products, pharmaceutical substances, and intermediates.

The IT infrastructure had grown organically since its inception and it was becoming difficult to manage across three locations, including Corporate and manufacturing locations. It was becoming imperative to upgrade their systems, OS and infrastructure and thereby transform the business capabilities by adopting IT best practices, tools, and architecture. Optimizing and improving the network connectivity between the manufacturing facilities at 3 different locations was required. The in-house IT team found it difficult to keep up with the changing pace of desktop technology, end-user computing devices, security policy implementation, standardization of operating systems and, backing up of end point devices due to lack of skilled in-house resources. The enterprise wanted a partner to implement and manage the VDI setup for 1000 users spread across 3 locations.

Anunta engaged to provide a VDI environment with maximum benefit by improving manageability, security, and enhanced user experience for applications that are accessed by its employees. We also provided centralized remote management and monitoring services for the VDI environment and currently supporting 2700+ users.

Complex IT Management:

Difficulties in managing the complexity of the operations, particularly change management was resulting in lack of end-user satisfaction and productivity loss. Additionally, poor control over the application environment and license compliance requirements further increased IT inefficiencies. IT teams were facing difficulties while managing network issues, server errors, misconfigurations, and security breach.

On-going Monitoring:

There was a lack of continuous monitoring of the virtual desktop environment like user issues, continuous peaks in a day or week, moving averages , consistent utilization level breaches, etc. The IT team wanted deeper insights into the overall health of the IT infrastructure of the company.


The IT team was finding it difficult to ramp up or down the capacity depending on the utilization and to manage any additions or deletions of the user profiles. There was no systematic process for capacity planning and sending capacity-based alerts resulting in delayed response to business needs.


The solution had to meet the company security requirements and create a complete data protected environment. The client wanted to ensure that the employees had secure access only to profile specific business applications.

What Anunta Did

Anunta identified the use cases and validated the desktop, OS, application requirements, policies, and licensing requirements. Based on information gathered about the applications, desktops, and user distribution landscape, it designed and implemented the virtual desktops on Citrix XenDesktop with Xenserver hypervisor for 300 users initially and additional 700 users with 100% concurrent users. High availability (HA) database servers, connection servers, and UAG servers were setup. The team created three golden images and deployed Key Management Server (KMS) for volume activation of Microsoft products (Windows OS and MS Office).

A cluster of two load balancers were recommended for two datacenters. The load balancers were integrated with VDI infrastructure to provide seamless load balancing and failover. Two Factor Authentication and biometric were integrated for all users to ensure secure access.

The virtual desktops were configured as part of the active directory domain with all group policies including password length, resets, and deletion or creation of users applied. The team ensured the desktops were built as per the security guidelines and applied patches, updates, and hot fixes to the systems with an end-to-end antivirus protection to ensure security.

Anunta designed and implemented end to end monitoring and management of the virtual desktop infrastructure using its cross-domain expertise and remote support capabilities. The ongoing support offered a unified framework for incident, change and problem management for desktop, servers, storage, data center, networks, telecom, and entire spectrum of IT services.

Anunta also provided service desk support services, including incident, problem, change, and patch management for the desktop environment that helped their IT team to focus on core business activities.
