In this talk, we'll look at Limelight's global CDN architecture and the practice of large scale web operations with FreeBSD. We'll investigate how FreeBSD makes these tasks easier and the strategies and tools we've developed to run our operations. We'll then look at why the engineering team chose SaltStack to further improve our operations capabilities and reduce deployment and fault handling times. Finally, we'll finish up with an overview of metrics and monitoring at scale with Zabbix and OpenTSDB. Limelight Networks is one of the "Big Three" CDNs and runs its edge using FreeBSD.
