It includes an AI-optimized hybrid cloud management solution, enabling efficient AI training and inference.

Background

To date, government and critical-sector applications in India have been hosted in on-premises environments. But with interoperability issues, high total cost of ownership, non-scalable architecture, and difficulties integrating new technologies, the cloud has become the alternative of choice. That said, exposing sensitive data in U.S. public clouds—which are subject to US FISA and the Cloud Act—is simply not an option.

After launching its offering in India’s public and regulated sectors, TCS is now expanding into the European sovereignty market

TCS: The choice partner for building India's sovereign cloud

TCS has been a strategic IT partner of the Indian government for many years. The digital services company has designed and managed several national programs aimed at strengthening digital infrastructure and citizen services, including passport issuance, health insurance, financial inclusion, investment facilitation, and pension management.

This expertise in the public sector gives it a unique advantage in building India’s sovereign cloud—a secure platform powered by AI.

A sovereignty built on the European model with extensive european partners

Europe sovereignty sets an example beyond its borders. TCS SovereignSecure Cloud will provide a dedicated infrastructure and a governance layer (Framework), enabling companies to define their sovereignty with regards to data and services criticality levels.

TCS guarantees that the data and application environment will remain under european jurisdiction and control. The only way to achieve this, aside from encryption and zero-trust access, is to minimize reliance on foreign software and services. Which is why OpenStack was chosen.

Through a risk-based approach, its Sovereign consulting and delivery framework will help companies strike the ideal balance between total control and flexibility

TCS will also rely on an extensive partner ecosystem (European infrastructure and data centre partners to support sovereign models deployments.

TCS SovereignSecure Cloud will also feature sovereign AI, a ready-to-use, AI-optimized hybrid cloud with high-performance computing (HPC) capabilities, scalable storage, and on-demand GPU availability to efficiently support training and inference.

Preconfigured modules and APIs will ensure seamless integration into government workflows and high-level security (fully private AI models, boxed LLM hosting with end-to-end encryption, and access controls).
