Yotta Data Services and BHASHINI have completed deployment of a sovereign AI cloud on Yotta's Government Community Cloud and Shakti Cloud, advancing India's capacity for self-reliant, scalable AI. The migration places language datasets, models and citizen interactions within Indian jurisdiction. The initiative aligns with IndiaAI Mission objectives and establishes a national reference architecture. The deployment was presented at the India AI Sovereignty Dialogues, a pre-summit event of the AI Impact Summit, and described in the Sovereign AI Cloud Transformation Report. The report draws on a trial at the Maha Kumbh 2025 where multilingual services operated at population scale. Powered by Yotta's NVIDIA H100-enabled Shakti Cloud, the platform delivered real-time translation and voice assistance across 11 or more Indian languages and introduced a multilingual assistant named Kumbh SahAIyak. The migration yielded up to 40 per cent performance improvement, 20 to 30 per cent cost savings and sustained 99.99 per cent uptime. The transition recorded zero data loss across more than 200 TiB of data and three point five billion (bn) files. These results were achieved while operating a full AI stack including datasets, models, APIs and containerised services. The migration was executed over a two-to-three-month period and adopted open-source, cloud-agnostic components to reinforce vendor neutrality and strategic autonomy. The architecture is modular and designed as a reusable national framework for ministries, public sector units and large national programmes. The design provides a clear blueprint for hyperscaler-to-Indian-cloud transitions. Officials described the deployment as a defining moment for India's data sovereignty and as validation that mission-critical AI platforms can be operated entirely on sovereign infrastructure. They indicated that the platform strengthens capacity to deliver inclusive, real-time multilingual services at population scale and will serve as a blueprint for future public sector AI initiatives. The development supports India's ambition to position AI as a secure, inclusive public utility that promotes economic growth and digital inclusion.
