Operating Systems Used by IT Giants: Infosys, TCS, Wipro, and Cognizant

In today's rapidly evolving technology landscape, the choice of operating system (OS) is crucial for the successful management of projects by leading IT firms. This article explores the diverse operating systems used by Infosys, TCS, Wipro, and Cognizant, highlighting their specific requirements and the reasons behind their choices.

Overview of Operating System Usage in Major IT Firms

IT organizations like Infosys, TCS, Wipro, and Cognizant operate in complex environments with varied project needs. Consequently, they employ a wide range of operating systems depending on specific project requirements, client preferences, and technological compatibility. Here’s a detailed look at the operating systems predominantly used by these companies:

Windows

Windows remains a popular choice for general office tasks, development, and testing purposes. Given its widespread compatibility and extensive software ecosystems, it is widely utilized in a variety of roles. In a recent survey, it was noted that around 80% of IT organizations prefer Windows 7 for their projects. For specialized environments, modifications and updates often occur via a virtual machine (VM) environment such as VMware VDI, primarily using Windows 10.

Linux

In server-side applications and environments where open-source solutions are cherished, Linux is a common choice. This operating system is particularly favored by developers and IT professionals due to its flexibility and robustness in handling complex and scalable projects. Organizations like Wipro and Cognizant often use Linux for its stability and low maintenance costs, especially in cloud and web server environments.

Unix

Projects that involve legacy systems or specific enterprise applications may opt for Unix-based systems. Unix offers a reliable and secure operating environment that supports both traditional and modern applications. For example, Unix can be seen in mainframe environments and specific vertical market solutions where robustness and reliability are critical.

MacOS

For roles involving design and development, MacOS is sometimes preferred due to its user-friendly interface and specialized tools for designers and creatives. Professionals in areas such as graphic design, animation, and advanced coding may opt for MacOS for its advanced features and integration possibilities with web-based tools.

Project-Specific Requirements and Client Specifications

The choice of operating system is not without variability. It often depends on the project requirements, specific objectives, and client specifications. A diverse range of operating systems is typically employed, ranging from Windows 10 to legacy versions like Windows 7 and even Windows 8. In a past experience at Cognizant, for instance, the choice of Ubuntu with IntelliJ IDEA and MacOS with Coda or vim highlighted the need for flexibility in operating system usage.

Earlier, the preferred OS was Windows XP, but due to its end-of-life status, Windows 7 and, in some cases, Windows 8 have become more prevalent. The transition from XP to newer versions underscores the dynamic nature of IT infrastructure management and the constant need for upgrading for improved security and performance.

Centralized Systems and Virtual Machines

The systems in these organizations are often centrally controlled and monitored, ensuring a standardized and secure environment. Updates are typically managed through a test-and-push approach, where new updates are first tested in a controlled environment before being deployed across the network. This ensures minimal disruptions to ongoing projects and maintains high levels of system reliability.

In conclusion, the operating systems used by Infosys, TCS, Wipro, and Cognizant reflect the diverse and complex nature of their operations. The flexibility in choosing between Windows, Linux, Unix, and MacOS allows these organizations to meet the varied demands of their projects and clients effectively.
