File Storage System Design
A startup is building a cloud file storage service to compete with established players. The initial version needs to allow users to securely upload their personal files to the cloud and access them from anywhere. The system must handle files up to 100MB in size, support concurrent uploads and downloads, and ensure file integrity throughout the process. User experience during slow network conditions and interruptions is critical for adoption.
As the Technical Lead, you've been tasked with addressing this challenge. The CTO and CPO have outlined the following requirements:
Design a system that allows users to upload files up to 100MB in size
Implement reliable and resumable upload/download mechanisms
Ensure file integrity verification for all transfers
Create efficient file metadata indexing for quick retrieval
Build secure authentication and authorization for file access
