how much ram do i need to run a server with red5 and broadcast live video
I am starting a project that will include live video broadcasts from all over the world and it is expected to have at least 1000 users viewing those videos in real time.
After looking around a bit i have decided to use RED5 to handle all the video streaming/recording, based on the fact that it is free and open source, but i am still open to other options (that don't include buying a FMS license).
now i need to know how many resources will red5 be demanding to the server if lots of users start accessing the site and watching the videos that maybe 50 different people are broadcasting.
i was thinking on renting a VPS with 512 MB of ram and 800 GB of bandwidth,
will that be enough? will i need to get something with more resources?, maybe a dedicated server?
or maybe the best thing for me to do is rent some hosting that offers video streaming services of some kind?
