A web-based application for uploading, downloading, previewing, and managing PDF and DOCX files. Built to provide secure, scalable, and efficient file management.
- File Upload & Download: Upload PDF/DOCX files to the server and download them as needed.
- File Preview: Preview files before downloading to review their contents.
- File Management: Delete files from the server and save downloaded files to your device.
- Responsive UI: Mobile-friendly and accessible on various devices.
- Secure Storage: Leverages AWS S3 for secure, reliable, and scalable file storage as files grow.
- Automated Server Management: Configured Systemd on Linux to run the application server as a background service for automatic startup and reliable request handling.
- Optimized Deployment: Deployed on AWS EC2 (t2.micro) with Nginx as a reverse proxy and static file server for optimized performance and security.
- Reduced Latency: Integrated AWS Cloudfront CDN for caching files, enabling faster delivery and reduced latency.
- AWS S3: Used for secure, scalable file storage.
- AWS EC2: Hosts the application server.
- AWS Cloudfront: Integrated Cloudfront CDN for caching files.
- AWS Lambda: Integrated AWS Lambda for deleting files in the background asychronously.
- AWS SQS: Integrated AWS SQS to capture failed delete operations for processing later.
- AWS IAM: Assigned IAM roles to different services like Lambda, EC2, SQS to interact with each other.
- Nginx: Acting as a reverse proxy and static file server for React build files.
- Multipart Uploads: Integrating S3 multipart file uploads enabling to upload large files conveniently and at a faster rate
- Load Testing: Integrating load testing for APIs to understand bottlenecks and latency
- Pagination: Implement for listing publicly available files, reducing bandwidth and resource overload.
- AWS OpenSearch: Integrate for faster document search functionality.
