The AI Infrastructure Boom
Artificial Intelligence is no longer a futuristic concept; it's the primary engine driving a colossal global infrastructure expansion. The overwhelming
message from the AI Impact Summit 2026 underscored the unprecedented acceleration in AI demand, necessitating stronger, faster, and more dependable data centers. From everyday AI queries and the intricacies of electric vehicles to the vast consumption of streaming platforms, data centers have evolved into the foundational pillars of our digital economy. In India, the world's third-largest economy, this trend is particularly pronounced. The nation is actively preparing to potentially host the planet's largest data center in Jamnagar, signifying a significant move in the ongoing global AI competition. This burgeoning momentum is already evident, with a major tech company recently announcing a substantial $15 billion investment dedicated to an AI data center in Andhra Pradesh, representing its largest investment in India.
