Aegis leverages end-to-end Citrix solution to centralize architecture

Aegis is a leading global outsourcing and technology services company wholly owned by Essar. Present in 44 locations across 9 countries and with over 40,000 employees, it manages almost 500 million customer interactions every year for over 150 clients across diverse sectors.

In India, Aegis operates over 30 delivery centres across multiple cities, with each delivery centre having an independent IT setup, be it an Active Directory or an anti-virus server. Having a distributed architecture brought along the challenge of having distributed data backup solutions and stand-alone storage across the enterprise.

The management of desktops was an even bigger issue with too many sites and endpoints to look after and manage. “Considering we serve multiple customers from all these 30-plus delivery centres, there are a wide variety of applications that we need to run on each and every desktop as per the clients’ requirements. Thus, desktop management was becoming very difficult,” says Ganapathy Subramaniyan, Aegis SVP and CIO.

This also had an impact on the lead time to update any changes or install new applications for a specific customer or a new business opportunity. “Having a distributed architecture, every site would have its own problems. So, when we actually wanted to install anything common across all sites, we had bigger issues,” explains Subramaniyan.

To overcome these challenges, Aegis decided to move toward a centralized architecture through desktop and server virtualization. “After evaluating our server footprint, we realized that virtualization provided the solution to many of the problems that we faced with a distributed architecture,” says Subramaniyan.

Holistic solution from Citrix simplifies distributed IT architecture

Aegis chose Citrix because of its holistic solution that included desktop, server, and application virtualization with XenApp, XenDesktop, and XenServer, and application delivery control with NetScaler.

Specifically with XenServer, the biggest advantage it offered Aegis was an unlimited number of licenses.

“There was a compelling reason for us to go for a complete Citrix solution. Citrix had the complete and right set of products to help us get all the benefits together and to address all the issues from having a distributed IT infrastructure. Also, getting the entire portfolio from one vendor ensured seamless integration, better management and convenience,” explains Subramaniyan.

Citrix also offered professional consulting services to perform a health check and audit of the complete IT environment, and provide recommendations around optimizing the infrastructure, including network parameters, network core configuration, and WAN configuration.

Aegis deployed rolled out the Citrix solutions in phases across the 30 data centers. In terms of footprint, the company has covered around 3,000 users on VDI with 9,000 users accessing applications delivered by XenApp. Both VDI and XenApp are hosted by 350-plus instances of XenServer. Besides these two, some of the other workloads hosted on XenServer are database, application servers, and all Windows Infrastructure Services (AD, DHCP, etc.).

During the implementation process, the biggest challenge faced by Subramaniyan’s team was that most of the applications needed to be tested on the VDI for each and every customer that Aegis was serving. This entire exercise took the company almost a year to complete considering the large portfolio of customers.

After moving to the Citrix environment, the company has benefitted on both business and IT management fronts. XenServer has helped consolidate the IT infrastructure, bringing the server footprint down by almost 40 percent while drastically shrinking the storage footprint by 60 percent, leading to cost savings.

Aegis also benefited significantly from having a central access to everything, as it made the deployment and management of applications much easier and less time consuming. “Earlier it was a nightmare for us to roll out any new applications that my client would want to install on some of the desktops across multiple sites. Now it is just a matter of few hours for us to release a new application across the organization as compared to what used to take days earlier,” says Subramaniyan.

Aegis moved from desktop to a thin client environment, considerably reducing the time it takes to deploy a new workstation. They also don’t need local support at the sites, which helps them better utilize resources. VDI has also allowed them to reduce power consumption, leading to savings in utility costs.

The centralized architecture has simplified overall and end-point audits. Considering everything is now consolidated and centrally done, the auditor is able to conduct the checks at the data center level and doesn’t have to visit individual delivery centers.

“Today our IT infrastructure runs like well-oiled machinery, without any issues. All that is possible by having the complete set of Citrix solution in our environment,” concludes Subramaniyan.
