Do you know how to implement a website like that? And what computer hardware should be using?
Should we run an actual Android/iOS phone behind?
Welcome to talk!
How powerful those servers should be? You know, even on a plain PC, it would take dozens of seconds and 512MB/1GB+ RAM to boot.
If they did what you assume, the powerful PC should be very powerful.
And in the frontend-programming, the webpage can talk with VMs in Ajax or persistent socket connection, e.g. TCP connection via websockets. And the message protocol for persistence can be specific.
"jslinux" uses ajax to fetch binary from server and runs it locally in web browser. It does not need any internet connection after that. The JS VM actually runs in your browser other than from any server. I think this is different from what http://manymo.com does.
Here's is the picture. http://imgur.com/XRvvw8N
I did an investigation of its internet traffic in Chrome and see this http://imgur.com/XI3Rpy0 and this http://imgur.com/EEutJ6a .
It shows that Manymo uses Ajax and Websockets to talk with clients. Ajax for fetching materials and websockets for keeping persistence.
I did several projects using both/either Ajax and/or websockets, this web tech is so familiar. But what I am concerned now is what behind the VMs are and how they implement those VMs.
Using QEMU??
