Video Pipeline for VOD And Live Streaming

Server Bandwidth Usage Analysis with/without CDN

Media Server Specs (AWS EC2):

OS:	 x64_linux_4.14.181-142.260.amzn2.x86_64
CPU:	 1 x Intel(R) Xeon(R) CPU E5-2676 v3     @ 2.40GHz
Memory:	 983 MB
Node.js: v14.5.0

Start of Node Media Server - 0 Viewer

- 0 HTTP request
- Server output bandwidth = 6 mbps.

Node Media Server without AWS Cloudfront(CDN) - 25 Viewers

- 25 HTTP requests (1 request for every viewer)
- Server output bandwidth = 200+ mbps.

Node Media Server with AWS Cloudfront(CDN) - 25 Viewers

- 1 HTTP requests 
- Server bandwidth = stable 10 mbps.

Observation

• As we can see from the bandwidth usage, without using CDN all viewer will request video from server thus increasing server burden on uploading bandwidth.
• By using AWS Cloudfront(CDN), it effectively reduced server bandwidth by making only one request to server and serve them through it's own CDN servers.
