How AWS, Microsoft, Google, Adani and Reliance are driving India’s data centre boom

The rapid expansion of data centres in India is being propelled by major global players such as AWS, Microsoft, Google, Adani, and Reliance. This surge is not merely a reflection of increasing digital activity but is also a response to the growing demands of artificial intelligence (AI) and cloud computing. As digital interactions—ranging from online payments to streaming services—become ubiquitous, the infrastructure supporting these activities is evolving into a critical component of the global economy.

Data centres, often referred to as the 'invisible plumbing' of the Internet, are now recognized as essential hubs for processing vast amounts of data. The industry has adopted a unique way of measuring capacity, using the electrical power available to IT equipment, expressed in megawatts (MW) or gigawatts (GW), rather than traditional metrics like floor area or server count. According to real estate consultant Knight Frank, global live IT capacity is projected to reach approximately 60 GW by 2025, with estimates suggesting it could exceed 93 GW by 2027. Another consultancy, JLL, anticipates that up to 100 GW of new capacity could emerge by 2030, underscoring the urgency and scale of this growth.

The Evolution of Data Centres

The evolution of data centres has been closely linked to technological advancements and changing computing needs. Their origins date back to the mid-20th century when early mainframe computers necessitated dedicated spaces with specialized cooling systems. The U.S. Army's ENIAC, completed in 1945, is one of the earliest examples of such facilities.

As businesses adopted mainframe systems in the 1960s and 1970s, dedicated computer facilities became more prevalent. IBM played a significant role in standardizing these sites, which catered to the growing demand for large-scale data processing. The 1980s marked a shift to client-server architecture, leading to the establishment of centralized data centres.

The 1990s saw a surge in demand driven by the Internet, as companies required reliable infrastructure to host websites and online services. The advent of virtualization in the 2000s further transformed data centres, making them more scalable and flexible. The 2010s introduced hyperscale data centres designed for technology giants, while edge computing began to emerge, bringing processing closer to users.

Today, data centres are being reshaped by AI, which demands significantly more computing power. This shift is accompanied by an increased focus on sustainability, as operators seek to reduce energy consumption and environmental impact. Modern data centres resemble military facilities, characterized by stringent security measures and advanced infrastructure designed to handle immense volumes of data.

The Indian Data Centre Landscape

In India, the data centre market is experiencing rapid growth, albeit from a smaller base compared to countries like the United States and China. Despite generating about 20% of the world's digital data, India's data centre capacity is projected to rise from approximately 0.375 GW in 2020 to around 1.5 GW by 2025, with estimates suggesting a potential three to seven-fold increase by 2030, reaching capacities of 4.5 to 10 GW. Major cities like Mumbai and Chennai dominate the landscape due to their proximity to sub-sea cable landing stations.

Hyperscalers, which are large cloud providers, currently account for over half of India's data centre IT capacity. Other significant sectors include banking, financial services, insurance (BFSI), and IT & Telecom. The rise of hyperscale data centres is indicative of the increasing demand for cloud services, as these facilities are designed to accommodate the massive processing needs of modern applications.

The financial dynamics of data centres are complex, with costs largely driven by IT equipment, engineering, and cooling systems. Traditional data centres are built on-site and expanded gradually, while modular facilities utilize prefabricated units, significantly reducing construction time. However, the rapid scaling of data centres raises concerns about their impact on local power grids, water resources, and infrastructure.

Why it matters

The implications of this data centre boom are profound for both creators and technologists. For creators, the increasing availability of cloud computing resources means more opportunities to leverage AI and other advanced technologies in their projects. As data centres become more efficient and scalable, creators can access powerful computing capabilities without the need for significant upfront investment in hardware.

For technologists, the evolving landscape of data centres presents both challenges and opportunities. The demand for AI-capable infrastructure necessitates a focus on energy efficiency and sustainability, pushing technologists to innovate in areas such as cooling technologies and power distribution. Furthermore, the rapid growth of data centres highlights the need for robust cybersecurity measures, as these facilities become prime targets for cyberattacks.

As India continues to expand its data centre capabilities, the interplay between technological advancement, energy consumption, and infrastructure development will shape the future of digital interactions. The ongoing evolution of data centres will not only support the burgeoning digital economy but also redefine how businesses and individuals engage with technology in the years to come.
