Yesterday, I gave a talk at SLUG (the Sydney Linux Users Group) about the open source software that we’re using in Vquence. The talk was basically structured into three areas: open source software in business operations, in software development, and in system operations. John joined in for the harder questions on the systems operations. We also explained how we’ve set our systems up so we are scalable on data (in particular on video slices, images and video use statistics) at a minimum cost – which includes the use of Amazon’s EC2 and S3 services. We also use reverse proxies to be scalable with bandwidth cost. Here are the talk slides.
