Beyond Websockets: turbocharged toolbox for realtime in the Cloud

When we say “realtime” in a web context, we generally think about Websockets or comet (long polling or streaming). Those are often the best options when a browser is involved (let alone native push on some mobile devices).

But let’s think out of the browser for one second, and review other options. Do we want all our services to talk among one other using HTTP? What about DNode, or ZeroMQ?

We will review a non-exhaustive list of some awesome tools that can help you to develop better realtime apps. Have one node handle millions of concurrent connections, hundreds of thousands of queries per second.

Moving to deployment options, we will discuss how we apply these concepts to run realtime apps at scale on dotCloud.

Half sysadmin, half developer, Jérôme is now working at the PaaS provider dotCloud, where he wears the hats of Evangelist, Support Ninja, and Ops Guru.

Before joining dotCloud, he also co-founded Enix, french provider for cloud and virtualization services since 2005. He holds a Master's Degree in Fundamental and Applied Computer Science from the University of Marne-la-Vallée in Paris, France.

When he's not hacking on his computer, he can be seen cooking, or heard playing the piano, the bass, or the theremin.
