Building a Serverless Multi-Tenant Platform for Secure Document Sharing
Founder’s Data Room is a secure, multi-tenant web platform designed for managing and sharing confidential documents across organizations. The client required a scalable, serverless, and highly secure environment to handle sensitive data, automate user access workflows, and ensure seamless document synchronization through Google Drive integration all while maintaining strict role-based access control and compliance standards.
Client Overview
Founder’s Data Room is a secure, multi-tenant platform designed for managing and sharing sensitive documents. It provides role-based access (Admin/Super Admin), cross-tenant permissions, and seamless integration with Google Drive for document organization and sharing. The client required a highly secure, scalable, and automated backend environment capable of handling dynamic document workflows and user management across multiple tenants.
Business Challenge
The client faced challenges with securely managing multi-tenant data, handling document synchronization at scale, and automating backend processes without compromising performance. Manual operations limited scalability, while maintaining consistent file-sharing permissions across tenants proved complex. The solution required a serverless architecture that could ensure real-time document processing, minimize infrastructure overhead, and maintain strict data isolation for each tenant.
Multi-Tenant Data Management
Managing separate data environments for each tenant while ensuring complete isolation and security.
Automation Gaps
Manual file synchronization and user management processes slowed operations.
Access Control Complexity
Difficulty maintaining role-based access across different tenants and user types.
Scalability Limitations
Existing architecture couldn’t handle growing workloads efficiently.
Cost Overhead
Maintaining traditional infrastructure increased operational expenses and maintenance time.
Engagement Objectives
Primary goals of the engagement included:
- Design a serverless and scalable AWS-based backend architecture.
- Enable secure document sharing with Google Drive integration.
- Implement automated workflows for user onboarding and notifications.
- Ensure multi-tenant isolation with granular access control.
- Achieve cost efficiency through pay-per-use compute services.
- Deliver zero-downtime deployments via automation.
