Agenda entry: The CentraStage experience, Ian van Reenen, CTO CentraStage: With 200,000 distributed agents with persistent SSL connections, keeping them all alive in the cloud can be a challenge. In this talk Ian will share the learnings of CentraStage regarding ELB vs HAProxy, and give insight into their strategies to cater for connection avalanches after outages.

Organiser's comment: Our first double-act as Ian from CentraStage brought up his DevOps lead, Jason, for a strong discussion-led session about how CentraStage have worked with ELB and HAProxy. This was a great talk with some really engaging Q&A, thanks guys for bringing us an interesting topic.
