Vex.dev is a startup that provides APIs for video and audio streaming. The hard part is real-time combined with massive scale - think hundreds of thousands of concurrent connections. They achieve this by using a combination of Fly.io, AWS and GCP. Jason Carter, founder of Vex Communications, is joining us today to talk about the multi-cloud setup that vex.dev runs.
