Defining Sovereign Cloud in the Indian Context

Sovereign Cloud in India is an infrastructure model where data storage, processing, and management occur solely under Indian jurisdiction, governed by local entities, using compliant infrastructure stacks. It mandates:

• All data and compute remain in-country.

• Legal and operational control by Indian entities.

• Adherence to DPDPA 2023 and sector-specific regulatory norms (RBI, IRDAI, SEBI).

• Limits on cross-border flow unless via approved frameworks.

This ensures digital sovereignty, regulatory compliance, and the capture of economic value from digital infrastructure.

Strategic Opportunities & Challenges

Strategic Advantages

• Ensures legal, regulatory, and cyber-resilience for sensitive and government-critical workloads.

• Supports AI/ML infrastructure sovereignty, enabling training & inference on in-country GPUs without foreign reliance (e.g., E2E’s TIR platform with H100/H200 GPUs) Elets eGov+4TimesTech+4The Times of India+4NDTV Profit+2TCS+2Forbes India+2.

• Positions India as a digital infrastructure hub for Asia–Africa, capturing economic value and enabling policy control.

Key Constraints & Frictions

• High cost and duplication: maintaining parallel architecture for sovereign vs global workloads raises CAPEX.

• Vendor lock‑in: limited local operators with fully sovereign stacks; reliance on global JV/cloud players.

• Fragmentation risk: segmenting global vs sovereign services may disrupt multi-region replication efforts.

• Permitting friction: average 24–30 month timelines for new builds hamper speed at scale Intelics Cloud+2Value Research Online+2The Times of India+2TimesTechForbes India.

• Skill scarcity: shortage of certified sovereign-stack designers, engineers, and localizable tech.
