I don't like this at all. "Scaling" usually refers to how easy it is to just add more hardware to the problem. But the thing that really irks me is the discussion of caching reverse proxies and partial page caching. Those optimization tec

nginx front end -> haproxy -> caching engine -> haproxy -> app instances (multiply this stack N times) haproxy's HTTP feature set is comparatively limited and we simply have too much traffic to put one machine in front of a

Nginx is incredible. It's my second favorite piece of software (haproxy wins by a hair). At justin.tv we serve tens of billions of requests per month using nginx, and it uses so few system resources that we can run our CPU-heavy caching e

How else are they going to pay for their free , high performance DNS servers and network? Not a bad tradeoff, really. Google can justify the expense of their DNS service w/ NXDomain's because it will speed up all of their web properties a

I would be very careful with gearman. We tested it at Justin.tv and managed to cause the main process (gearmand) to spin at 100%, stop accepting connections, and lots of other things. Not quite ready for production use, especially if you n

Actually we don't have any bitrate limitations. I've seen users push 8mb streams before, but most people chose lower bitrates because very few viewers have the bandwidth and CPU required to enjoy those streams. You make a very good point a

Try doing faster than realtime transcoding of 2000 simultaneous streams. Not that trivial.

Justin.tv and Weebly run their own networks. We have BGP-speaking routers that announce our own IP address prefixes to the global internet routing table via multiple transit providers.

Yes, that's exactly why it's more costly to serve static video. Live video can be served straight out of memory, which is cheap. The cost of software to stream live video has pretty much dropped to zero as well.

You're generally right on #2 and #3. Even the biggest IP transit networks in the world only have capacity on the order of a few terabits per second (or a few million simultaneous video streams). However, "bandwidth" isn't really what matte

We've tried several vendors at Justin.tv, but we always end up circling back to Dell. Pricing is great, spare parts are readily available on Ebay, and they're quality machines. Definitely get in touch will their sales guys and plan your p

You can broadcast in 720p resolution, but most users choose not to since the player is only 320x240 (unless you go to full screen mode).

We've been using these for about a month at Justin.tv. They are awesome. Capacity increased from about 350mbps per m1.x-large instance to nearly 700mbps per c1.x-large instance.
