Inventor(s) include Dr. Subasree S; Surendiran; Vijayaragavan G; Sarvanth D; and Ruban K.
The application for the patent was published on Jan. 23, under issue no. 04/2026.
According to the abstract released by the Intellectual Property India: "The increased use of centralized public cloud infrastructures brings many challenges concerning data sovereignty, unpredictable egress costs, and adherence to stringent compliance regulations. The following work proposes HostVault, a self-hosted cloud storage platform that can work as a resilient and autonomous private-cloud platform to address these core limitations. It is a system that embodies an architectural model based on High Availability (HA), service segregation, and multi-host deployment, reflecting enterprise-level reliability. Successful implementation required establishing continuity of service through a redundant framework. This includes the Nginx load balancer, which constantly conducts health checks of two different instances of the Python Flask application to ensure seamless failover upon node failure. Data integrity was ensured by the use of a centralized PostgreSQL database acting as the authoritative source for metadata, with streaming replication providing real-time redundancy to a standby instance. Unstructured data is stored on a distributed MinlO object storage cluster. Efficiency in the system is enhanced with direct stream processing for file I/O, enabling the Flask application to serve as a lightweight conduit rather than as a memory buffer for large files. Security has also been enhanced through rate limiting with Flask-Limiter, backed by the Flask-SQLAIchemy ORM to prevent SQL injection. The key utilization of this project is to deliver a functional and strategically favorable alternative to public cloud services. HostVault provides full data sovereignty and absolute control over digital resources, meeting critical compliance needs. Economically, the architecture counters the variable cost structure of the public providers on a direct basis. By eliminating unpredictable egress fees, the system offers a highly predictable TOO based on fixed capital expenditure, thereby showing how a resilient, cost-efficient, and fully autonomous private cloud model-essential for organizational operations- requires predictable operating costs and strict data sovereignty."
