• I. Use AWS S3
• II. Standard process

I. Use AWS S3

AWS S3 has huge internet bandwidth and resources. Basically we can pay for their service only.

• Generate S3 signed URL to upload
• Upload file from client (browser) to AWS S3 directly
• Use AWS Lambda to execute file processing such as Media convert, capture thumbnail, etc…
• Notify to backend server and update related data

II. Standard process

Standard process will be applied to single server or media server over nginx web server with these steps

• Upload file from browser to server
• Create Queue process for video converting, capture thumbnail, etc…
• Update status of media file once done
• Notify to API server (can use redis pub/sub, kafka, or simple with internal restAPI)
