Can this technology stack scale? [closed]

manpreet Best Answer 2 years ago

My client ask me to build a realtime application that could chat, send images and videos all in realtime. He asked me to come up with my own technology stack, so I did a lot of research and found out that the easiest one to build would be using below tech stack

1) Node.js and cluster to max out the CPU core for one instance of server - Language

2) Socket.io - realtime framework

3) Redis - pub/sub for multiple instances of server

4) Nginx - to reverse proxy and load balance multiple servers

5) Amazon EC2 - to run the server

6) Amazon S3 and CloudFront - to save the images/videos and to deliver

Correct me if I'm wrong for the above stack. My real question is, can the above tech stack scale 1,000,000 messages per seconds (text, images, videos)?

Anyone who have experienced with node.js and socket.io, could give me an insights or an alternatives of the above stack.
