Sharing Slides with 10,000 People in r/t: Socket.IO and Node.JS in Production

Wednesday 20 Mar 2013 from 6:30pm - 8:30pm

Cinchcast is an innovative new platform that enables large-scale conference calls and webcasts for your business. Our webcasting solution must be able to securely push out slides to tens of thousands of people while synchronizing with the audio stream. In this talk, we will discuss how we used NodeJS and Socket.IO to achieve this goal. Socket.IO has tremendous capabilities to overcome limitations of the web sockets in the browser ecosystem today. However, leveraging and scaling this framework can be both challenging and interesting across multiple servers: How do you keep state? Why do connections begin getting dropped? Is it really secure? We will answer all of these questions in this talk. We will focus on understanding Socket.IO scalability and high availability, and discuss some security pitfalls that you need to watch out for.
