Justin.tv was an early live video streaming platform that grew rapidly after launching in 2007, reaching 300 broadcasters and 6 million monthly page views within a few months. As traffic increased, the engineering team encountered challenges scaling their initial architectures to support thousands of concurrent streams. They eventually found success using Amazon Web Services, which allowed them to scale elastically and reliably support over 1,000 broadcasters streaming to 100,000 concurrent viewers at lower cost compared to traditional hosting options.
